Two Way Radios Move from Analog to Digital with a Gateway

For companies to be efficiently functional in today's digital world, tapping modern communication tools is inevitable. Communication, after all, is fundamental to virtually all types of organizations. Supervisors communicate to team members to relay instructions; team members communicate with each other to accomplish tasks. And if you're organization is relying on two-way radios to communicate, it's high time to invest in radio over IP rather than analog methods in today’s digital landscape. 

What Is Radio over IP In The First Place?

Today, almost everyone relies on the Internet, and Internet Protocol (IP) infrastructures are ubiquitous.

RoIP or Radio over IP, voice packets are sent and received by radio devices over an existing IP infrastructure such as a Local Area Network (LAN’s) or a Wide Area Network (WAN’s). This means that when you call someone through a radio device, your voice won't be transmitted via the conventional cables, radio frequencies, microwave transmitters, and antennas. It will be sent via the internet, which is way faster, more secure, and more reliable. 

However, RoIP isn't just limited to transmitting voice data. They can also transfer any other data signals produced by Land Mobile Radios (LMRs). 

What Are RoIP Gateways?

Gateways for RoIP systems are designed to transmit and receive audio signals used by radio devices over the internet, providing advanced connection options to established IP networks. These devices are meant to help entities leverage RoIP as a cost-effective way of interconnecting radio systems, including a radio dispatch console and dispatch operators. 

A great thing about a RoIP gateway is that it's not just the traditional analog radios or push-to-talk devices that can be integrated into it. Because this technology is interoperable with other communication devices, you can also use it with more modern VoIP phones, tablets, and even desktop computers. 

With this integration of traditional radio devices with advanced digital gadgets, your organization can enjoy a unified network where you can communicate — minus the gaps, lags, and limitations attached to analog radio systems without having to upgrade your analog radio hardware right away. 

Typically, the management and configuration for RoIP gateways are done using a web browser. You can use a standard web interface to achieve a setting that meets your organization's unique communication needs. 

If you're looking for a gateway for your RoIP system, it's also better to invest in a device that can simultaneously run multiple protocols, serving as a conference bridge across several interfaces. 

Why Move From Analog To Digital?

Now the help of gateways for RoIP systems, you can shift your organization's communication system from a costly analog-based system to a digitally powered one without having to update the more expensive radio frequency architecture. But why tap the power of this kind of technology? 

One of its greatest advantages using a small radio over IP systems is cost-effectiveness. The infrastructure used to facilitate and maintain traditional radio communication systems is expensive and unreliable. But with RoIP, you can economically connect your communication devices all while getting a cleaner signal and more reliable connection. And as mentioned, it boasts superior interoperability, making it easier for you to scale up or down your communication system. 

RoIP also features better security. With routers and firewalls, your organization's network — and the voice packets and other data signals that you transmit — remain protected against various security threats. 

Radio Over IP Is Not New Just More Affordable

Radio over IP is an effective and low cost solution for those companies that are using older hardware for two way radio communications to connect with employees, security teams and service personnel and just don’t have the dollars to upgrade to all new digital mobile radios throughout their organization.

Using radio over the Internet is no longer a new means of communication. Just like VoIP communications, the sound of your voice needs to be converted into a digital signal that travels over your existing network or the internet. The device that does this conversion is called a voice encoder or vocoder. Converting analog voice signals to a digital format also is old technology that dates back to the 1950’s. The telecom giants have been digitizing and packetizing digital voice for many years. What is new is how analog radio communications are able to take advantage of digital vocoders and RoIP gateways to transmit digital voice with a minimal investment.

RoIP is a smarter alternative to the more conventional radio systems. Some of the radio over IP applications are large entertainment venues, metropolitan bus and train transportation networks, large field services teams that deploy engineers and technicians for repairs and campus security teams for universities, business campuses and manufacturing organizations that are spread across acres. If you have people in the field at different locations, it is more practical and less costly to have a digital mobile radio communications rather than using cellular networks. The system works by establishing a Session Initiation Protocol. A connection is made between two parties on the Internet. The server compresses the voice traffic into digital streams and sends them through this connection.

RoIP systems have proven to be cost-effective, reliable, and highly flexible. It has enabled workers and managers involved in large projects that are spread over a large geographic area to communicate with one another. You can put your RoIP system on the same network as your computer system, which makes it easy to maintain the security of both.

If you have decided to invest in this technology, it is important to take robust measures to secure it. Red/black switching is a type of encryption protocol that has been in sue by the department of defense and public safety operations for years and is now available to more commercial applications. Working with a company that is familiar with secure voice communications would be an important criterion in your selection process. Deploying a red black encryption system on your own is not advisable.

Gateways for RoIP systems have become smaller, smarter and more affordable in the past few years. The vendor you work with should be transparent from the beginning. They should offer you a range of options and be open about the advantages and disadvantages of each. Your people will also need training on the new system and therefore the communication systems provider you choose should include training into their package. This is especially important if you plan to put the RoIP system in the field right away.

In addition to training your people, the vendor should commit themselves to providing maintenance for at least a 2-year period. Should anything go wrong with the system, then the communication systems company in the USA you had install and program your RoIP gateways must be available to resolve any issue.

Radio Over IP Provides Reliable Communication for Bus Fleets

Reliable communication is vitally important for a bus fleet for reasons of safety as well as logistics. However, the analog communication systems used in the past to connect fleet drivers and dispatchers have distinct disadvantages when it comes to reliability. Drivers that have to drive long distances on their routes may travel out of range of the traditional land mobile radio system. Additionally, geographic features and topographic variations can interfere with the operation of an analog LMRS system. Transportation companies are increasingly turning to radio over IP systems to increase both the range and reliability of communications, as well as reaping additional benefits.

What Exactly Is RoIP?

To understand what radio over internet protocol means, it is first necessary to understand its predecessor: voice over IP. VoIP involves voice and data communication over the internet as opposed to the analog system which delivered voice communications over a system of traditional telephone networks, T1 lines and copper wires. VoIP involves converting the sound waves into digital signals for transmission via broadband and then translating them back into audio signals once they have reached their destination.

Radio over IP functions according to the same principle as VoIP and utilizes the same type of technology. The main difference is that RoIP converts two way radio signals between two points. Analog radio communications uses VHP and UHF frequencies, In the digital space, the voice data is converted into digital voice packet and now piggyback existing IP networks.

Why is RoIP More Reliable?

With an analog radio system, communication can be disrupted by geographic features that can interfere with the transmission of radio waves. These include hills, mountains, buildings with thick walls, tall or dense trees, etc. Since RoIP communication takes place over existing LAN and wide area networks, the digital voice packets and not impacted by physical features and are uninterrupted data packets. The lack of interference makes it more reliable.

Even the most sophisticated LMRS has limitations to its range of functionality. If a fleet driver travels beyond that area from necessity, communication can no longer take place between the driver and dispatch and/or other members of the fleet. Gateways for RoIP systems are the tools that convert the voice signals to digital packets and therefore are very important to the entrance into the IP networks they will travel. IP networks are as ubiquitous today as cell phones. Evan an eskimo in a remote region of Alaska can access the internet today.

Outages are a concern for anyone who uses the public internet but in most cases, RoIP communications tap into private networks for travel. Providers understand the need for consistent services when providing RoIP for transportation and therefore the routing configurations are a key ingredient when programing the gateway for RoIP systems. Therefore, the networks they are programed for are set up to continue to function fully even during a partial failure. The rare outages that do occur are usually resolved quickly.

What Are Additional Benefits of RoIP for a Fleet?

In addition to increased reliability, radio over IP offers additional benefits to a transportation company:

• Interoperability

• Speed

• Affordability

From the point of view of the end-user, there may be little discernible difference between RoIP and traditional LMRS. The former's interoperability allows drivers and dispatchers to use the same legacy devices to which they are already accustomed, while at the same time enjoying the additional benefits of clarity and reliability. Because the investment into hardware is minimal, RoIP for a fleet of buses, service vehicles or event a network metropolitan trains is a less expensive way for a fleet to upgrade their communications. RoIP for transportation networks is more common in 2019 than ever before. The technology is sound and chances are your communications system provider can point you in the right direction.
