TP-Link Archer MR600

Trying to find a way (without tethering) to turn your mobile data plan into a useful Wi-Fi network supporting ethernet connections at home, at the office, or on the go used to be an almost impossibility.

The hardware to pull this off either wasn’t all that great, affordable or flat out didn’t perform to expectations until just a few short years ago. Today, however –…

Nowadays we often hear that customers want to use a router feature called Link Aggregation. Here we can simply discuss about the Link Aggregation, also called Link Bonding by other users.

What is link aggregation? Link aggregation is a way of bundling a bunch of individual (Ethernet) links together so they act as a single logical link. Why we will use link aggregation? If you have a switch with a lot of Gigabit Ethernet ports, you can connect all of them to another device that also has a bunch of ports and balance the traffic among these links to improve performance.

Another important reason for using link aggregation is to provide fast and link recovery in case one of the individual links fails.

Individual packets are kept intact and sent from one device to the other over one of the links. In fact, the protocol usually tries to keep whole sessions on a single link. A packet from the next conversation could go over a different link.

The idea is to achieve improved performance by transmitting several packets simultaneously over different links. But standard Ethernet link aggregation never chops up the packet and sends the bits over different links.

The official IEEE standard for link aggregation used to be called 802.3ad, but now is 802.1AX, which I will explain later. A group of ports combined together is called a link aggregation group, or LAG. Different vendors have their own terms for the concept. A LAG can also be called a port-channel, a bond, or a team.

The rule that defines which packets are sent along which link is called the scheduling algorithm. The active monitoring protocol that allows devices to include or remove individual links from the LAG is called Link Aggregation Control Protocol (LACP)

The first important thing to know is that all links in a LAG must be a type of Ethernet (10/100/1000/10G, etc) and they must all be identical. LACP can’t balance traffic among two Gigabit Ethernet links and a 100Mbps Ethernet link, for example. If you try, the devices will refuse to include the different link in the LAG. They might even refuse to bring up the LAG.

Further, all the links must be configured the same way. You can’t have a mix of duplex settings or different VLAN configurations or queuing features. You can put a maximum of eight individual links in a LAG group, although some devices will restrict you to a smaller number. That said, because of the simple way most of the scheduling algorithms work, you’ll generally get better, more even load balancing if you use an even number, and preferably a power of 2 such as 2, 4, or 8.

An important concept of link aggregation is that all the packets belonging to any individual session should go down the same single link. Otherwise you risk out-of-order packets, which would cause serious problems for a lot of applications.

It’s important to note that two devices connected by link aggregation don’t need to agree on the load balancing algorithm. The goal is to select an algorithm that randomizes your packets as much as possible. That way you can expect fairly use of all the links, which will provide the best possible performance.

On a general switched Layer 2 network with a lot of devices talking across the aggregated link in arbitrary patterns among themselves, the simplest MAC address hashing algorithm works well. Even if most of the traffic involves devices talking to a single central server, the algorithm still works well because the randomness of the MAC addresses of the other devices ensures reasonably even load balancing.

However, if the link is basically just two devices talking directly to one another across an aggregated link, then a MAC-based load balancing algorithm means all the traffic uses just one of the links.

This is the case, for example, if you have two routers (or Layer 3 switches) or two firewalls, or one of each talking across the link. You might be communicating with the whole Internet, but if all the packets are going to the same firewall, that’s one MAC address. And if all the packets are coming from one core switch, that’s also one MAC address. So a hash based only on MAC addresses won’t give you any performance advantage in such cases. In situations like this, it’s useful to use IP addresses in the load balancing algorithm.

You can easily tell whether your load balancing algorithm is appropriate by looking at the link utilizations on each of the individual links in a bundle using the “show interface” command. If you see that one link is consistently more heavily utilized, then it might be a good idea to change your algorithm.

Note that when you change the algorithm on a device, you only change how that device behaves when sending packets. If the traffic imbalance is in the inbound direct, representing received packets, then you need to adjust the device on the other end.

A big question you’ll have to answer when configuring a port-channel is whether to configure it to be active or merely on. The active option means the device will actively monitor the status of the link and automatically remove any failed links from the bundle. This is obviously a very good idea because it gives you fault tolerance as well as load sharing. So why would anybody ever opt not to use it? The short answer is compatibility. If the device on one side of the link decides one of the individual connections is bad, then the device on the other end should really agree. Otherwise one device will keep dumping packets down a link that the other device isn’t watching.

A lot of server implementations don’t seem to implement the standard properly, or they cut corners and don’t implement the active monitoring function at all. I usually make everything active and only change to on if I run into trouble with it.

The 4G industrial router is simply based on the common router, providing the industrial version design and 4G network access to high-speed networking equipment. It usually has WIFI wireless LAN function, supports 4G LTE network system, and is compatible with 2G/3G network. And according to the priority of 4g-> 3g-> 2G, the network is automatically selected.

How 4G industrial routers work

The principle of 4G industrial router is also very simple. Users can only insert a SIM card into the 4G industrial router, and the dial-up network through 4G network can realize high-speed Internet access and remote data exchange transmission. The WIFI function of 4G industrial routers can also realize network sharing and data transmission within short distance or local area network. From the point of view of using method alone, the idiotic operation of 4G industrial router is favored by the market public.

Features of 4G industrial routers

4G industrial routers tend to be outdoor and practical. They are mainly used for industrial control projects, so they have high requirements for environmental adaptation, safety protection and appearance protection.

Application range of 4G industrial routers

Currently widely used in the industries of M2M in IoT industry chain, such as industrial control network, the smart grid, personal health care, intelligent transportation, smart home, financial, mobile POS terminals, supply chain automation, industrial automation, intelligent building, fire control, public security, environmental protection, meteorology, digital medical treatment, remote sensing survey, agriculture, forestry, water, coal, petrochemical and other fields.

Influence factors of the transmission range

In practical application, the transmission range of industrial wireless routers is affected by many factors.

First of all, many people don't have a clear understanding of the transmission range of industrial wireless 4g routers. Generally, the wireless network signals of industrial wireless routers are marked in the manual.

However, this is not the case. The theoretical data are obtained in an ideal test environment. The specific influencing factors are as follows:

Factor 1: Affected by the router's own transmitting power. This is the decisive factor affecting the transmission range of industrial wireless routers. The higher the power, the wider the transmission range, but according to relevant national regulations, the maximum transmission power shall not exceed 100MW, i.e., 20dBm (2.4 GHz frequency band). Because the higher the power, the greater the radiation, this is harmful to the human body.

Factor 2: Affected by terrain and obstacles. The practical application environment of routers is complex and changeable, so it is hard to find the wireless signal range value in the test environment, which is mainly affected by the environment and obstacles and interferes with the wireless network. Among them, the barrier walls with glass and metal have the biggest influence on the signal of industrial wireless routers.

Factor 3: High gain antenna can increase the stable receiving distance. Gain is to increase the power density ratio of the signal generated at the same point in space between the actual antenna and the ideal radiation unit and enhance the transmission range when the transmission power is certain.

Factor 4: Weather. Industrial wireless routers are different from ordinary routers in home. They are mostly used in outdoor environments, which determines that they are greatly affected by weather. The harsh outdoor environment also puts forward high requirements for the anti-oxidation and high protection of the router chip.

When users choose industrial wireless routers, they can choose products with appropriate power and gain antennas according to their own needs and use them in open areas as far as possible, which can maximize the transmission range of routers.

 ----------------------------------------------

A router (Router, also known as a path) is a computer network device that transmits packets through a network to the destination (selecting the transmission path of the data), a process called routing. A router is a device that connects more than two individual networks, and routing works on the third layer of the OSI model-the network layer, such as the Internet Protocol, IP layer.

Basic introduction

Router (Router), is connected to the Internet in each LAN, WAN equipment, it will automatically select and set the route according to the situation of the channel, to the best path, in order to send the signal before and after. Routers are the hub of the internet, "traffic police". At present, routers have been widely used in all walks of life, a variety of different grades of products has become the backbone of a variety of internal connections, backbone network interconnection and backbone network and Internet interconnection business. The main difference between routing and switching is that the switch occurs at the second layer of the OSI Reference Model (the Data Link layer), and the routing occurs on the third layer, the network layer. This difference determines that the routing and switch need to use different control information in the process of moving information, so the two ways to achieve their respective functions are different.

Main Features

The router has the function of judging the network address and choosing the IP path, it can establish the flexible connection in the multi-network environment, the different data grouping and the media access method may connect each kind of subnet, the router only accepts the source station or other router's information, belongs to the network layer one kind of interconnection equipment.

It does not care about the hardware devices used by each subnet, but requires running software that is consistent with the Network layer protocol.

Routers are local routers and remote routers, the local routers are used to connect network transport media, such as optical fiber, coaxial cable, twisted pair; a remote router is used to connect remote transmission media and requires appropriate devices such as telephone lines to be equipped with modems, wireless via wireless receivers, transmitters. Routers are the main node devices of the Internet. Routers determine the forwarding of data through routing. The forwarding strategy is called routing (routing), which is also the origin of the router name (router, forwarding). As the hub of interconnection between different networks, the router system constitutes the main thread of Internet based on TCP/IP, and it can be said that routers constitute the skeleton of the Internet. Its processing speed is one of the main bottlenecks of network communication, and its reliability and stability directly affect the quality of network interconnection.

Therefore, in the park intranet, regional intranet, and even the whole Internet research field, the router technology is always at the core position, its development course and direction, become a miniature of the whole internet research.

In the current China's network infrastructure and information construction in the ascendant, to explore the role of routers in the interconnection network, status and development direction, for the domestic network technology research, network construction, and clear network market for routers and network interconnection of various plausible concepts, are of great significance. In recent years, the Exchange router products, in essence, it is not a new technology, but to improve communication capabilities, the principle of the switch to the router, so that the data transmission capacity faster and better.

Action function

1. Connect to different networks

From the point of view of filtering network traffic, the function of router is very similar to that of switch and Network Bridge. However, unlike the switches that work on the network physical layer and physically divide the network segment, routers use specialized software protocols to logically divide the entire network. For example, a router that supports IP protocols can divide the network into multiple subnet segments, and only network traffic that points to a particular IP address can pass through the router. For each received packet, the router recalculates its checksum and writes the new physical address. Therefore, the speed with which data is forwarded and filtered by routers is often slower than the switch that only looks at the physical address of the packet. However, for those networks with complex structures, using routers can improve the overall efficiency of the network. Another obvious advantage of routers is that they can automatically filter webcasts. Overall, the entire installation process of adding routers to a network is much more complex than a Plug and play switch.

2.     Select a route for information transfer

Some routers only support a single protocol, but most routers can support the transmission of multiple protocols, that is, multi-protocol routers. Since each protocol has its own rules, it is bound to degrade the performance of routers in order to complete multiple protocols in a router. The main task of the router is to find an optimal transmission path for each data frame passing through the router and to effectively transfer the data to the destination site. This shows that the choice of the best path strategy is the routing algorithm is the key to the router. In order to do this, the relevant data-the path table (Routing table) of various transmission paths are stored in the router for routing purposes. The path table holds the logo information of the subnet, the number of routers on the network, and the name of the next router.

The path table can be fixed by the system administrator, or can be dynamically modified by the system, can be automatically adjusted by the router, can also be controlled by the host.

Static routing table: by the system administrator set up a fixed path table is called a static path table, is generally installed in the system according to the configuration of the network pre-set, it will not change with the future network structure changes. Dynamic routing Table: Dynamic path table is the path table that the router adjusts automatically according to the network system's operation. Routers provide the functions of the routing protocol (Routing Protocol) to automatically learn and memorize network operations and automatically calculate the best path for data transfer when needed.

Router level

1.     Access router

The access router connects Small business customers within the home or ISP. The access router has started not only to provide slip or PPP connections, but also to support virtual private network protocols such as PPTP and IPsec. These protocols should be able to run on each port. Technologies such as ADSL will quickly increase the bandwidth available to households, which will further increase the burden on access routers.

As a result of these trends, access routers will support many heterogeneous and high-speed ports in the future, and will be able to run multiple protocols on each port while avoiding telephone switching networks.

2.     Enterprise-Class Routers

Enterprise or campus-level routers connect many terminal systems with the primary goal of achieving as many endpoint interconnects as possible, and further requiring support for different quality of service. Many existing enterprise networks are Ethernet segments that are connected by a hub or network bridge. Although these devices are inexpensive, easy to install, and require no configuration, they do not support service levels. In contrast, a network with routers involved can divide a machine into multiple collision domains, and thus be able to control the size of a network. In addition, routers support a certain level of service, allowing at least several priority levels to be divided. However, the cost per port of a router is more expensive, and a lot of configuration work is needed before it can be used. Therefore, the success of the enterprise router is whether to provide a large number of ports and the cost per port is very low, whether it is easy to configure, whether to support QoS. Enterprise-class routers are also required to effectively support broadcast and multicast. The corporate network also handles a variety of legacy LAN technologies and supports a variety of protocols, including IP, IPX, and Vine. They also support firewalls, packet filtering, and a large number of management and security policies, as well as VLANs.

3.                  Backbone-level routers

Backbone routers realize the interconnection of enterprise-level networks. The demand for it is speed and reliability, while the price is subordinated. Hardware reliability can be obtained by using the technology used in telephone switching networks, such as hot backup, dual power supply, and dual data access. These technologies are almost standard for all backbone routers. The main performance bottleneck of a backbone IP router is the time it takes to find a route in a forwarding publication. When a packet is received, the input port looks for the destination of the packet in the forwarding address to determine its destination port, which increases the cost of routing lookups when the packet is shorter or when the package is destined for many destination ports. Therefore, putting some of the frequently accessed destination ports into the cache can improve the efficiency of routing lookups. Both the input buffer and the output buffer router have the bottleneck problem of routing lookup.

In addition to performance bottlenecks, the stability of routers is a frequently overlooked issue.

4.                  Too-bit routers

Of the three main technologies used in the future of the core Internet, fiber optics and DWDM are already mature and readily available. The development of high-performance backbone switching/routers (too bit routers) has become an urgent requirement without routers that correspond to the original bandwidth provided by existing optical fiber technology and DWDM technology, and the new network infrastructure will not be able to fundamentally improve performance. Too-bit router technology is now mainly in the development of experimental phase.

5.                  Multi-Wan router

Dual-Wan routers have a physical 2 WAN ports as external network access, so that the intranet computer can go through the dual WAN Router load balancing function at the same time using 2 external network access lines, greatly improve the network bandwidth.

The current dual-WAN router has the advantage of "bandwidth convergence" and "one Network and two lines", which is not to be done by traditional single WAN routers.

Functional level

1. Broadband router

Broadband router is a new network product in recent years, it comes into being with the popularization of broadband. Broadband routers in a compact box integrated router, firewall, bandwidth control and management functions, with fast forwarding capabilities, flexible network management and rich network status and so on. Most broadband routers are optimized for China's broadband applications, which can meet different network traffic environment, and have good adaptability and network compatibility. Most broadband routers use highly integrated design, integrated 10/100mbps Broadband Ethernet WAN interface, and built-in multiple-port 10/100mbps adaptive switch, convenient for multiple machines to connect the internal network and the Internet, can be widely used in families, schools, offices, Internet cafes, community access, government, enterprises and other occasions.

2. Modular Router

The modular router mainly refers to the router's interface type and the partial extension function is can according to the user actual demand to configure the router, these routers in the factory generally only provides the most basic route function, the user may choose the corresponding module according to the network type which the connection wants to connect, Different modules can provide different connection and management functions. For example, most modular routers allow users to choose the network interface type, some modular routers can provide functional modules such as VPN, and some modular routers also provide firewall functions, and so on. Most routers today are modular routers.

3. Non-modular router

Non-modular routers are low-end routers, usually at home for this type of non-modular routers. This class of routers is primarily used to connect small business customers within a home or ISP. It not only provides slip or PPP connections, it also supports virtual private network protocols such as PPTP and IPsec. These protocols should be able to run on each port. Technologies such as ADSL will soon improve the broadband available to households, which will further increase the burden on access routers.

As a result of these trends, this class of routers will support many heterogeneous and high-speed ports in the future, and will be able to run multiple protocols on each port while avoiding telephone switching networks.

4. Virtual router

Virtual router to be virtual truth. Recently, a number of new breakthroughs in IP backbone network equipment have paved the way for the realization of new Internet services in the future. Virtual routers are a new technology that makes it possible for some new internet services. With these new services, users will be able to control the performance of the network, Internet address and routing, and network security.

The Israeli R&D Network company is a manufacturer of LAN to WAN solutions, which first proposed the concept of virtual routing.

5. Core router

The core router, also known as "backbone router," is a router located in the center of the network. The router at the edge of the network is called an access router. Core routers and edge routers are relative concepts. They all belong to the router, but they have different sizes and capacities. A layer of core routers is another layer of edge routers.

6. Wireless router

Wireless router is a wireless coverage of the router, which is mainly used for user access to the Internet and wireless coverage.

Popular wireless routers in the market generally support dedicated line xdsl/cable, dynamic XDSL, PPTP Four kinds of access mode, it also has some other functions of network management, such as DHCP service, NAT firewall, MAC address filtering and so on.

7. Single ARM router

The concept of a one-armed router is to appear in the three-tier switch, the network between the VLAN communication can be implemented with ISL, in that case, the router becomes a "single arm router", the data between the VLAN to enter the first router processing, and then output, In order to make most of the message in the same VLAN in the network will not need to pass through the router directly between the switching device for high-speed transmission. The disadvantage of this routing method is that it is still a centralized routing strategy, so the backbone network generally set up a number of redundant "single arm" routers to share data processing tasks, which can reduce bottlenecks caused by routers, but also can increase redundant links, However, if there is a large amount of data transfer between VLANs in the network, bottlenecks will be formed at the router.

Single-arm routers are now largely replaced by layer 3rd switches.

8. Wireless network router

A wireless network router is a communication device used to connect to a wired and wireless network, and it can send and receive wireless signals via Wi-Fi technology to communicate with personal digital assistants and laptops.

A wireless network router can easily set up a computer network without a cable. However, it is generally possible that the speed of the data transmission outside the wireless network is affected by the weather. Other wireless networks include infrared, Bluetooth and satellite microwaves.

9. Intelligent Flow Control Router

Intelligent flow Control Router can adjust the bandwidth of each node automatically, so that the speed of each node can reach the fastest, do not limit the rate of each node, this is its biggest feature. Intelligent Stream control routers are often used on the main roads of telecommunications, such as Huawei, Cisco.

Internet cafes, hotels and other common network star routers.

10. Dynamic Speed Limit Router

The dynamic speed-limiting router is a kind of bandwidth that can calculate the needs of each user in real time. Accurate analysis of user access type, and reasonable allocation of bandwidth, to achieve on demand, reasonable use, but also has a priority channel of intelligent provisioning function, this function is mainly used in Internet cafes, hotels, communities, schools and so on, the most commonly used internet cafes are audio center routers.

11. Soft Router

The use of desktop or server with the software to form a routing solution, mainly relying on software settings, to achieve the function of the router, the common grass soft routes, sea spiders and so on.

 -------------------------------------------

5G is the next generation of mobile networking technology following 4G. Much like every generation before it, 5G aims to make mobile communication faster and more reliable as more and more devices go online.

Unlike years before when mobile networks only needed to support cell phones that were just for browsing the web and text messaging, we now have all sorts of bandwidth-demanding devices like our HD-streaming smartphones, watches with data plans, always-on security cameras, self-driving and internet-connected cars, and other promising devices like health sensors and untethered AR and VR hardware.

As billions more devices connect to the web, the entire infrastructure needs to accommodate the traffic to not only support faster connections but also better handle simultaneous connections and provide broader coverage for these devices. This is what 5G is all about.

How Is 5G Different Than the Other “Gs”?

5G is simply the next numbered generation following 4G, which replaced all of the older technologies.

-1G introduced analog voice

-2G introduced digital voice

-3G ushered in mobile data

-4G paved the way for widespread mobile internet usage

What Will 5G Be Used For?

This might seem obvious given how ubiquitous smartphones are, but while phones are definitely a major player in mobile communication, they might not be the primary focus in a 5G network.

As you’ll see below, the key components with 5G are ultra-fast connections and minimal delays. While this is definitely great for anyone streaming videos from their phone, it’s more important in scenarios where minimizing delays is really important, like with the future of interconnected devices.

One application might be augmented reality devices or virtual reality headsets. These devices require a tremendous amount of bandwidth and need to communicate over the internet as quickly as possible to provide their intended effects. Any latency at all can drastically impact how real things feel in those environments.

The same applies to any other devices that need to act quickly, like autonomous cars to avoid sudden collisions and understand proper turn-by-turn directions, remotely operated hardware, and robotic systems that learn or abide by remote controllers.

With that being said, 5G will still pave the way for smoother connectivity from our everyday devices, too, like when gaming, making video calls, streaming movies, downloading files, sharing HD and 4K media, receiving real-time traffic updates, vlogging, etc.

5G is so fast that it won't just be available for mobile devices. It has the potential to even replace your cable through fixed wireless access! See our 5G Internet: The High-Speed Replacement for Cable article for more on this.

How Will 5G Work?

Standards for 5G aren't fully solidified just yet and service providers won't necessarily use the exact same technology to implement 5G, so it's hard to say exactly how it will work for every company in every country.

For example, in some cases, 5G will broadcast data at a totally different range of frequencies than existing networks. This higher range of waves is called millimeter waves, which operate at the 30 GHz to 300 GHz range (current networks use bands below 6 GHZ).

What makes this significant is that instead of a multitude of devices sharing a small space on that spectrum, they will be able to "spread out" on that line and use more bandwidth, which means faster speeds and less dropped connections.

However, while these higher frequency waves can carry more data, they can't broadcast as far as the lower ones, which is why some providers, particularly T-Mobile, will deliver 5G on the 600 MHz spectrum to start, and then likely other bands as time goes on.

Providers that do use higher frequencies might need to position small wireless stations between 5G towers to repeat the data in order to provide 5G speeds while at the same time covering more distance. Instead of broadcasting signals all over the place to reach nearby devices, these stations will probably use what's called beamforming to direct signals to specific targets.

This type of setup should allow for faster transmissions not only because there will be a number of stations to help relay the data at top speed, but because signals won't need to physically move as far to reach other devices. This device-to-device communication is what will allow for such low latency.

Once 5G is here and widely available, it's possible that it will be the last major advancement in mobile networking. Instead of a 6G or 7G later on, we might simply stick with 5G but get incremental improvements over time.

When Will 5G Come Out?

The timeframe for 5G service availability depends not only on where you live but also which service providers are available in your area.

See When Is 5G Coming to the US? For more information, or 5G Availability around the World if you're not in the US.

5G Specs: Data Rate, Latency, & More

5G seeks to improve several areas of mobile communication, from how fast you can download and upload data to the number of devices that can connect to the internet at the same time.

Data Rate

These are the minimum requirements for 5G peak data rates. In other words, it’s the bare minimum download and upload speed that each 5G cell must support, but it could fluctuate in some conditions.

-Download: 20 Gb/s (2.5 GB/s)

-Upload: 10 Gb/s (1.25 GB/s)

The numbers above are what each mobile station must support but that doesn’t mean that’s what your device will be capable of. That speed is split between all of the users connected to the same base station, making these rates a bit more realistic for each user:

-Download: 100 Mb/s (12.5 MB/s)

-Upload: 50 Mb/s (6.25 MB/s)

With 5G speeds, you could download a 3 GB movie to your phone in four minutes, or upload a 1 GB video to YouTube in just under three minutes.

For comparison, the average mobile download speed reported by Speedtest.net in 2017, for users in the United States, was around 22 Mbps—over four times slower than what's proposed by 5G.

Connection Density

At a minimum, 5G will support 1 million devices for every square kilometer (0.386 mile). This means that within that amount of space, 5G will be able to connect a whopping 1 million or more devices to the internet at the same time.

This type of scenario might seem hard to fathom considering cities with the highest population density (like Manila, Philippines, and Mumbai, India) only hold anywhere from 70,000 to 110,000 people for every square mile.

However, 5G doesn’t need to support a mere one or two devices per person but also everyone’s smartwatch, all the vehicles in the area that might be connected to the internet, smart door knobs in nearby houses, and any other current or to-be-released device that needs to be on the network.

Latency

Latency refers to the time lapse between when the cell tower sends data and when the destination device (like your phone) receives the data.

5G requires a minimum latency of just 4 ms assuming that ideal conditions are met, but could drop as low as 1 ms for some forms of communication, particularly ultra-reliable and low-latency communications (URLLC).

For comparison, the latency on a 4G network might be around 50-100 ms, which is actually more than twice as fast as the older 3G network!

Mobility

Mobility refers to the maximum speed at which a user can be traveling and still receive 5G service.

The 5G spec has defined four classes it will support, anywhere from a stationary person who isn’t moving to someone in a high-speed vehicle like a train, who’s traveling up to 500 kmh (310 mph).

It’s possible that different areas will require a different mobile base station to accommodate for varying speeds. For example, a small city that only has users traveling by car and foot might not have the same base station included in a larger city with a high-speed public transport system.

Power Consumption

Energy efficiency is another component called out in the 5G spec. Interfaces will be built to quickly adjust power usage based on their current load.

When a radio is not in use, it will drop down into a lower power state in less than 10 ms, and then readjust just as fast when more power is needed.
