Internet Protocol (IP) radio is an excellent way of sending and receiving audio or data-based digital voice packets. Using radio through IP gateways will allow you to piggyback on various LAN (Local Area Network) and WAN (Wide Area Network) networks. You can also use data and voice encryption at the gateway to achieve secure mobile communications. The benefits of using this technology radio over IP technology is to reduce unnecessary hardware costs, improved reliability, and better interoperability.

How Does Radio over IP Work?

Radio over IP (Internet Protocol) is the process of sending and receiving radio transmissions using portions of the Internet. It takes advantage of existing data networking protocols. Vocoders are used to convert analog voice signals into digital voice packets prior to transmission over IP networks. Routers encryption protocols and firewalls are used to secure a client’s network and the digital voice packets.

Radio over IP offers a low-cost way to upgrade older radio systems. Most organizations already have LAN or WAN suites built for networking, digital sharing, data storage and trasnmissions, which means there is no need to build a new communications suite before deploying a radio IP solution. Digitized voice packets sent over IP can be easily channeled to many of the older radio systems as well as newer land mobile radios. You can connect HF, UHF, and VHF radios with cell phones, VoIP phones, and SIP enabled devices, which will move your organization closer to unified communications.

If your operation requires secure mobile communications, then you may need a separate layer for encrypting digital radio packets and transmitting secure radio transmissions using IPsec protocols. Using radio encryption terminals will allow your team to carry out vital tasks while maintaining operational security.

Re-Making Secure Mobile Communications in Your Organization

If you need to upgrade and better encrypted VoIP switch, a more secure radio communications system in your organization, then you will need the best radio IP devices and equipment. This can only be found with a communication systems provider that understands radio signaling too. You need to install the proper radio over IP gateways to convert analog to digital packets but that may be the only piece of hardware you require. More secure mobile communications can be achieved through encryption protocols.

After a hurricane has ravaged an area, such as the devastation caused by Hurricane Michael in the panhandle of Florida, it is critical for communication to be established with utility restoration teams as soon as possible. Many times companies will send linemen and technicians from all over the country to help restore electricity, water, and communication to a community. Restoring communication isn’t just important for the community, but it is critical to the success and safety of those working to clean up the damage.

Cell Phones Aren’t Practical

Even though many people feel their cell phone will keep them connected during an emergency, natural disasters absolutely have the potential for damaging the cell phone infrastructure. Emergency responders and cleanup crews are ineffective if they are unable to communicate with a dispatcher, understand a coordinate where assistance is needed, obtain driving or navigation instructions during hazardous conditions, and send a request for supplies. Natural disasters often cause unstable working conditions, such as downed power lines, fragile networks and crumbling structures can create safety hazards. The ability to instantly communicate with one another in these situations can save lives.

Connecting With the Community

Keeping response crews safe isn’t the only job of reliable communications after a natural disaster. If there was very little warning and time to prepare, it is important to connect with schools, churches, businesses, and other installations concerning evacuation, aid, or shelters. Without the dependable system to communicate that isn’t susceptible to drastic weather interference, it can be a dangerous and chaotic situation as the community tries to move to safety and implement preparedness plans.

High-tech Radios

Building out a network for reliable radio communications is a step in the right direction. A RoIP for utility and cleanup crews allows for two way radio communications between men in the field and a central dispatch can speak freely over frequencies not hindered by cellular and telco communication sensitivities. These IP networks for radio communications use low voltage LAN and WAN hardware and have flexibility. With the right devices, crews can establish secure mobile communications and connect in two-way conversations much like a telephone call. In a situation where distance, obstacles, and power failures are interfering with connectivity, RoIP gateways allow for push to talk devices to be connected through a single home base. With options for connectivity from an IP address, it can support the analog radio functions with more reliability, greater reach, and interoperability.

Nigerian Civil Aviation Authority is immediately starting to demolish telecommunication masts that pose security risks to aviation in different areas of the country.

NCAA says the demolition exercise would similarly affect some banks and financial institutions that had discountenanced its regulatory requirements on the clearance for any high structure within navigable airspace in the country.
