Radio Communications Using Internet Protocols

You might be familiar with VoIP, but RoIP allows you to enjoy the same benefits - and more.

Daily operations of organizations across several sectors are more productive since making the leap from analog to digital voice communications. Voice over Internet Protocol (VoIP) technology has allowed us to send voice data to digital devices more affordably. Instead of exchanging data through an aging network of copper wires, ethernet switches, transponders and PBX servers, data is transmitted today via the internet in the form of digital packets. Today's secure communication systems rely on voice encryption to relay and receive information promptly and minimize the risk of various security threats.

Radio over IP or RoIP works under the same principles as VoIP, although radio communications require a digital gateway. Previously, radio users communicated via radio frequencies with the help of microwave transmitters, extenders and antennas. Now they're sending data digitally through a local or wide area networks.

This digitization of voice data has also addressed many of the critical flaws of analog-based radio communications. When signals are jammed or when the location of the other user is too far away, the transmission of voice data was negatively affected. Today an organization enjoys a larger service area with a RoIP-integrated communication system — typically composed of two-way radios, consoles, routers, and a RoIP gateway.

Apart from greater coverage, here are the advantages of RoIP:

Enhanced reliability. In some organizations, there's information that needs to be quickly communicated. For instance, emergency response teams have to deploy respondents as quickly as possible, with respondents in the field reporting back to dispatchers. Because an IP network is generally more resilient than its analog counterparts, more efficient communications can be experienced. The quality of voice data being transmitted is also better and has better security features. Therefore, less prone to data breaches and eavesdropping.

Better interoperability. A RoIP gateway links several radio systems over an IP network. In a RoIP-powered system, the communications interoperability of radio types and brands is also permitted. By allowing device flexibility, it is easier for you as an organization to add (or replace) new users to an existing IP network. Additionally, you'll have more freedom when it comes to choosing which manufacturer or products you'll integrate into your system, depending on your needs, preference, and budget.

Improved productivity. When you can connect multiple base stations over huge areas, you can minimize errors and lags in communication. From the standpoint of those in the operation center, it facilitates a more streamlined remote management. In general, it can increase the productivity of the organization.

Lower expenses. Traditional analog radio hardware is costly to install and maintain. Switching to a RoIP-based communications network is more financially friendly in the long run. In addition, digital radios are becoming more affordable, you can also find hardware (e.g. Routers and extenders) to add to your network through many different resources. Interoperability is a key ingredient when buying digital radio hardware. The costs for digital radio devices continues to be more affordable as the technology improves.

Easier to maintain and repair. Especially if you frequently have critical and emergency situations, your need for secure communication systems becomes even more important than ever. Radio over IP software allows for high levels of digital encryption and is easier to repair and restore connectivity gateways. This is also another way you can save money and enhance productivity — while protecting your organization's reputation in the process.

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. 

Radios Now Use IP Connections To Extend Reach

Since its invention in the late 1890s, the radio has been a reliable tool for communication. Fast forward to today, more secure radio communications are now in place thanks to different technologies, including encrypted Radio over IP and secured IP consoles. 

RoIP (Radio over IP), in particular, offers a cost-effective way to connect radio systems and operators.  Radio over IP can extend their reach over analog UHF and HF transmissions. You can use RoIP to enhance connectivity both between established radio communication channels and and newer digital mobile radios by employing gateways for RoIP systems. These RoIP gateways are needed if an organization is transitioning from traditional to radio network systems that transport voice and data via internet protocols. 

How It Works

RoIP works the same as the Voice of Internet Protocol or VoIP. In a nutshell, VoIP works by transforming analog voice calls into data packets and sending these packets of data over to another party over an IP network. In RoIP, a push-to-talk (PTT) capability can be incorporated, ensuring more secure radio communications. Think of it as the integration of VoIP technology in an existing two-way radio network. An encrypted VoIP to radio over IP arrangement adds an encryption layer to the data packets after they have been encoded.

In this system, at least one node should be a radio device. The other nodes can either be a radio or any other device that you can access via the Internet (e.g., smartphones, dispatch consoles, desktop, or mobile applications). 

What Are Its Perks

Many organizations — both private and public sectors — have already incorporated RoIP into their communications system. If you are contemplating investing in this technology and wish to employ gateways for RoIP systems, here are some of the benefits that you will enjoy.

Expanded reach. Traditional radio systems rely on  microwave transmitters and frequency boosters. Not only is this expensive to maintain and scale — but there are also limits in terms of location and other geographic barriers. With RoIP gateways, you can increase your service area and boost your network’s flexibility (e.g., you can configure simultaneous connections to different sites or add repeater sites and dispatch locations more quickly). 

Improved interoperability. You can route calls made via RoIP to almost any type of radio system as long as there is a digital decoder on the other end. By allowing a mixture of radio types and manufacturers to transmit via IP, scaling your communication system can be much more convenient. You would not have to worry about the compatibility of devices or range limitations as you take on more devices to your network. 

Greater reliability. With the help of a Communication systems company in the USA, any type of organization, especially in the public safety sector and upgrade analog radios to use a digital network. In an RoIP-powered network, the interconnection between nodes, devices, and users is stronger. And because your network would not be subjected to a single point of failure, you can save resources by with digital re-routing. This boost in reliability also comes with a significant security improvement when encryption keys are part of an added layer. RoIP gateway software and hardware can safeguard your network from unauthorized access as well as data leaks through encryption. 

Increased productivity. In an RoIP network, configuration, command and control, and maintenance are centralized. Because operations are hosted via the Internet, remote management is also possible. Furthermore, as mentioned, downtime can be minimized in this setup whenever an issue arises. All these give a boost to the organization’s overall level of productivity without necessarily having to shell out a huge amount for the incorporation, scaling, and maintenance of the RoIP technology. This high return on investment is one of the many reasons why more radio networks now use IP connections to boost and strengthen their reach.

Radios and Cell Phone Interoperability

The concept of secure radio communication systems can be traced back to the 1800s. More than two centuries later, the use of two-way radios has become dominant across several industries — from the police workforce, emergency use, the military to businesses and academic institutions. 

While this technology offers a number of advantages over more modern communication tools — including durability and reliability especially in remote locations — it can still be maximized through the concept of radio and cell phone interoperability. This breaks radio’s limitations and allows it to be operated along with other voice networks. 

The Emergence of Network-Based Solutions

To connect radios with cell phone users, radio communication systems should be integrated with other types of networks. But how do these network-based solutions work? 

The base of these solutions is an intelligent network composed of a server, a push-to-talk management center, routers and other components, and land mobile radio (LMR) gateways. The LMR gateway, in particular, is tasked to convert traffic coming from analog radios into Internet Protocol (IP) packets. With this, the network-based solution will be able to expand the traditional radio’s reach. In this network, radio channels are mapped to an IP multicast address — and any user that has access to IP-linked gadgets can join the previously closed-off push-to-talk network. 

The Advantages of IP-based Radio System

The benefits of having secure radio communication systems has been proven the ability to have private, uninterrupted conversations that prevents hackers and malicious persons from misusing when is transferred by the two parties communicating.

Radios communications can be enhanced once they become interoperable with other voice networks, including cellular phones. 

IP-based radio interoperability. which allows user to connect radios with cell phone user, offers the following advantages: 

It is easy to install, deploy, and use. Compared to other alternatives, IP-based networks are easier and quicker to install than building out a high frequency radio infrastructure. They are also easier to use and deploy, further boosting their cost-effectiveness. 

It makes communications more efficient. Once you make secure radio communication systems interoperable, it will be easier for you to make operations more seamless and communications, more efficient. With cellular network usage dominating communication traffic, the ability to connect radios with cell phone users allows for more efficient communications. Additionally, command-and-control features will become more streamlined — allowing you to save more of your resources in the process. 

It is scalable and flexible. Communication needs change as time goes by. What makes IP-based radio interoperability a superior solution is its flexibility and scalability. Layering on gateways for RoIP systems has become very simple for the entities involved. 

It offers security. Communication networks should first and foremost be secure. So should the network that allows the interoperability of two different voice networks. IP-based interoperability is known to offer more layers of security before a user gets access to a talk group. 

It offers better access to crucial data. Once a user enters a network via an RoIP gateway, he or she can gain access to database information (e.g. Geographic Information Systems data) and relay that data to anyone who might be needing it. Ultimately, this will create a communication platform that’s more resilient, efficient, and collaborative.


Mobile Command Vehicles Are State of the Art

Never has the importance of mobile command vehicles been stressed more than during big disasters like hurricane Katrina or today, as the world struggles with the the civil unrest in the US and the Covid-19 calamity. The political division in communities and cities across the US have demonstrated the need for communications control centers which should have been able to respond to the victims’ needs. This is why a lot of states are now investing in mobile command centers. Hopefully, these measures would save lives in the event of future demonstrations that turn violent. 

Why Are Mobile Command Centers So Important

Investing in a command and control console to help manage radio communications from these command centers is now necessary because natural calamities like earthquakes and floods can easily cripple a municipality’s communications center. How could rescuers communicate with their citizens in need and with each other if the primary command center is down? During Hurricane Katrina, a number of police stations were disabled and abandoned because of the flood. If there was only a more mobile and flexible command center that could move away from the hazard, rescuers would have been able to act more swiftly and more efficiently. 

Why Radio over IP (RoIP)?

While going mobile is ideal, it can be expensive if the communication channels are not chosen properly. RoIP for municipalities can provide the same accessibility without breaking the city’s budget. Why is it so affordable? RoIP uses the Internet which is more accessible and less expensive than analog radio networks using traditional communications antennas for VHF, UHF and High Frequency bandwidths. 

When RoIP is also integrated with existing network infrastructures like VPN, LAN, and WAN, there is no need to build a new network infrastructure using expensive hardware. Most companies and communities already have well established digital networks that digital mobile radio communications can piggyback on. A privacy partition and firewall are often already in place to protect network data and a RoIP gateway is a smaller piece of hardware that would be needed to bridge the gap. 

Reliability and productivity

RoIP communications can be controlled remotely using internet protocols to manage communication pathways. Should something happen to the mobile command center, the communications can be rerouted easily. Another remote base station using a laptop computer is often supporting backup operations. The communication lines can remain open as long as one party is still connected to the Internet. 

This means more reliability for these mobile command centers. There is a Plan B, a Plan C, and a Plan D should things go wrong in the handling of the rescue operations especially during a disaster. The best thing about this arrangement is that these backup plans do not require expensive hardware and the specialized skills of a communications engineer. 

The internet is a global infrastructure and as long as the software is configured with the right device IP’s, location of the communicants is less important. Imagine the possibility of having centralized strategies during these calamities. Since not all states are hit during a single calamity, it’s so much easier to send out aid for those who need them. 

Any Security Issues

Of course, RoIP solutions also need to be secure for it to be the ultimate solution. However, with the affordability of these RoIP solutions for municipalities, it’s easy to pair them up with firewalls and other security measures to ensure that no data is ever compromised.
