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.

Protect Yourself Against Top VoIP Security Threats

You must protect data, information, and confidentiality in your company. Nowadays that is not an easy thing to do. Hackers and snoopers of all sorts are constantly scavenging for information. You should assume that your company has been targeted and take appropriate action. 

One of the most effective ways to keep your voice communications secure is to install a VoIP phone system. VoIP stands for Voice over Internet Protocol. It is an alternative to the conventional telephone systems, which is also known as a public switched telephone network. VoIP is used by companies that have a distributed management and operations organization. If your company has people and business units all around the world, it is more practical and less costly to have a cloud-based phone systems.

There are plenty of companies that offer VoIP services. Radio communications are a bit more challenging to secure. More field based personnel are using digital mobile radio communications today. Using encrypted radio over IP (RoIP) is how to lock down those conversations. Security is one of the most important features of VoIP and RoIP systems. You and your colleagues should be able to make secure voice calls over ip but may require a communications system integrator to configure the encrypted VoIP to radio over IP components. 

How VoIP Works

In VoIP, calls are established using Session Initiation Protocol (SIP). A connection is made between two parties over the Internet backbone. The SIP server compresses voice traffic into digital streams and sends them through this connection. 

Companies have shifted to VoIP because it is cost-effective and flexible. If a large section of your workforce regularly works from home, using a VoIP network allows everyone to keep in contact and to share data and information. VoIP and computer systems use the same network, which means that your IT staff or IT provider must maintain only one secure network. 

The Realities of VoIP Security

The lower costs, increasing popularity and accessibility of VoIP makes it a target of attackers who wish to exploit it. The placement of malware on VoIP systems, the breaching of databases, and the institution of payment fraud are just some of the many threats and breaches that have occurred in VoIP networks. It is estimated that the cost of such breaches reached $8.1 million in the United States in 2019. Healthcare, finance, and energy are the industries most affected by VoIP hackers and cyber criminals. 

The top threats to VoIP systems include:

1. Denial of service 

This attack saps resources from the network to interrupt phones service.

2. War dialing 

In this attack, the assailant seizes control of your hosted PBX and uses it to scan other telephone networks. 

3. Phishing 

In this type of attack, unsuspecting victims are lured into divulging passwords and other sensitive data. 

5. Spam 

Involves the use of robocalls and other phone scams.

6. Malware 

This uses malicious software to infiltrate your network and gather sensitive data and information.

A typical communication systems company in the USA can make sure you own secure, quality products and you as the customer are completely satisfied. If you are looking for ways to improve your company’s communications system, you should make the switch to Voice over Internet Protocol (VoIP) and Radio over Internet Protocol (RoIP).

Bridging VoIP and Radio Communications With a Gateway

Radio transmission is used in many applications, including first responders, helicopters, hospitality, construction, maintenance and campus security. Voice over IP is used by large service providers to connect users for voice communications across broadband instead of traditional phone lines. RoIP or radio over IP is a similar philosophy but focuses solely on radio frequencies. It is made possible with RoIP gateways.

Voice over IP and radio over IP both use the same mechanism to transmit voice data. CODEC is used on the transmitting end to convert spoken messages to digital data. It is then assembled into UDP packets and transmitted at intervals. On the receiving end, the digitized UDP packets are converted by CODEC into the spoken voice you hear.

Common Applications of RoIP

If you are considering RoIP gateways but aren't sure if it is the right move for your business, it can be helpful to understand how it can expand your radio coverage. The most common applications are replacing a UHF/VHF link between repeaters, replacing the leased line connection from a console to a repeater, replacing the leased line connection between multiple repeaters, or increasing coverage over remote or steep terrain. Other applications include bridging multiple repeaters and connecting radio with PBX networks.

RoIP Connections

With RoIP, you can achieve access to remote radios and connect radios to dispatch consoles or a telephone gateway. The connections may be point-to-point, point-to-multipoint or cross-band, also known as unicast, multicast and conferences.

When one-to-one communication is critical, unicast transfers voice data to a single IP address. A point-to-multipoint or multicast transmission sends one RoIP packet simultaneously to several devices via a shared IP address. Cross-band or conferences allow multiple devices to share the same RoIP packet within the group. Conferences are similar to multicast but are much easier and more effective when used in larger networks.

Benefits of RoIP

There are many benefits of implementing gateways for RoIP systems:

• Interoperability between disparate radio systems like HF, UFH and VHF and corporate Voice over IP systems

• Less cost to upgrade infrastructure such as when replacing wireless links, leased lines and reduced cabling

• More reliable communication within an IP network

Voice and Video Conferencing Technology in the IP World of VoIP

Video conferencing is becoming an increasingly important part of how today’s companies do business. Throughout various sectors, companies are opting to conduct long-distance meetings and conversations via videoconferencing rather than the traditional conference call. The benefits of this approach include improved communication and stronger relationships. When video is not optimal for whatever reason, a high-quality voice conferencing system is best for facilitating the effective communication you may need.

For this reason, it is important to source voice and video conferencing technology that is cost-effective, reliable and meets your company’s specific needs. High-quality imaging is a must to reap the benefits of video conferencing, especially when you need to display video or image content. Priorities for this technology often include high audio and video quality as well as transmission speed.

Circuit Switching and Packet Switching

Standard phone systems use circuit switching to transmit data. This means the system selects a specific path to transmit all the data from the conference. This route is only used for that data so long as the session continues. Because you pay for the exclusive use of the bandwidth, this method tends to be more costly. Some types of videoconferencing use circuit switching.

The most common protocol for video and audio conferencing is packet switching, which uses IP-based networks. This protocol converts the information to a sequence of packets, then sends them. Each packet travels through the network separately. Because these routes are also used by others, this method does not cost as much.

On the other hand, this protocol on its own can result in a lower transmission quality, as the data packets do not have a dedicated circuit open for them and compete with other data traveling along the same route. VoIP uses packet switching; a high-quality communication systems provider will typically use additional protocols to increase reliability and transmission quality. There are also several methods to keep network conditions from affecting quality.

Types of Systems

Conferencing technology systems can come in a variety of configurations. These include systems that individuals can use on desktop computer or full featured smartphone. Set-ups for large audiences in a single room often rely of broadcast quality bandwidth dedicated to that production. A configuration optimal for conferencing in a large number of people in disparate locations may use an IP voice switch for the audio and a larger bandwidth on the same IP network for the video packets. Some video conferencing systems may have a voice switch baked into the system, allowing one person to speak and appear at a time. Others create the atmosphere of a meeting by showing everyone simultaneously.

Radio Over IP

Some companies, such as those operating mobile fleets, need to integrate their radio network to work over IP. VoIP to radio switching can be a cost-effective and reliable way to connect radio users and operators via dispatching hardware. Because the IP protocol can route the audio to a wide variety of radio types, it can make system-wide integration easier.

Benefits of Using Radio Over IP as Part of the Utility Storm Preparedness Plan

Utility workers need to communicate within a municipality during a storm. Communication is essential to shoring up flood areas, blocking off low water crossings overflowing with water, finding storm shelters, fixing downed power lines, testing the accessibility of clean water and more. Radio over IP helps workers go beyond the current analog signals. RoIP networks offer better interoperability and greater reliability if the local Wan or Lan access is still up and running. RoIP gateways can be the ticket to improved storm preparedness for your utility company.

Improved Function

Storm preparedness plans often include radios as the communication method of choice to deliver necessary information between various departments including utility companies, military personnel, emergency services and municipality offices. Relying only on radio frequencies can mean intermittent communication during a raging storm. Radio over internet protocol uses the internet to send and receive messages. Analog signals are converted to digital signals that travel over IP networks with a vocoder. These digital voice packets are protected with routers and firewalls using what is currently securing the IP network. The added avenues for communication allowed by RoIP for municipalities improves communications for improved efficiency and effective deployment of the storm preparedness plan. When departments can communicate with each other, they can effectively communicate with residents, help affected residents faster and set up barriers efficiently.

Cost Effective

Leveraging RoIP for municipalities is a cost-effective way to streamline effective communications between the various entities mobilized during a storm. RoIP gateways allow the utility companies to use existing LAN lines whether private or public without having to build new pathways for communication. The cost savings of RoIP for utility workers allows for more money to go toward necessary emergency items such as sand bags, storm shelters and life-saving equipment.

Improved Interoperability

Radio signals can send their digitized communications over IP networks. Interconnecting RoIP for utility workers with SIP enabled devices, cell phones and VoIP phones allows the workers to tap a larger network. Communicating between departments and units is faster and more reliable. Installing RoIP for municipalities as part of the storm preparedness plans ensures the utility companies receive training and practice to employ the devices with accuracy during an emergency. Using more than one pathway to communicate naturally increases the reliability of radio communication systems.

The benefits of RoIP for utility workers cannot be overstated. When it comes to storm preparedness, radios can be life savers. Increasing their effectiveness and reliability helps residents and workers alike. Homeowners wishing to increase their ability to communicate with the outside world during a storm may benefit from RoIP if they have the necessary devices.
