![]() Digital AES P25 provides the maximum security with 256 bit encryption.Digital DES P25 secure 56 bit encryption (mostly used by public services).DES 20 provides protection against more advanced types of listening technology.Rolling Code Encryption, This is available on more professional units and is a more robust technology for encryption.Voice Inversion Encryption this is a simple voice scrambling system used to prevent other radio users in your immediate area from listening to your conversations.Others offer a higher level of protection and do not unscramble easily by scanners or other surveillance devices. ![]() They range from basic to advances forms of protection. There are different types of encryption on walkie talkies, so it is important to find the level of privacy that meets your business requirements. EncryptionĮncryption scrambles the voice signal so other radios in your vicinity cannot listen in on your conversations. Also, radios that meet this standard have ‘Intrinsically Safe’ or ‘FM Approved’ written on their documentation. In order for manufacturers to sell these radios, they need to meet specific standards in order for a product to be certified as ‘Intrinsically Safe’. Furthermore, Intrinsically safe radios are designed so the electrical energy in the radio is low enough that ignition of the explosive gases do not occur. (IS) is a certification for electronic equipment in locations where explosive gases may be present. Think of it as lanes on a motorway people can share the same motorway (frequency), and PL tones are the lane markings that prevent drivers from running into each other (hearing each other). This allows channels in the same user environment to be shared but still maintain private conversations between users. PL tone and a PL code (also known as CTCSS)ĬTCSS is a sub-frequency that filters out other transmissions on the same frequency, in order to maintain privacy. ROIP allows two-way radio communication over the internet, thus letting you speak anywhere in the world. Consequently, this across a large geographic area. Usually, police forces and emergency services require trunking systems so that they can maintain contact with different departments. They consist of a network of multiple repeaters which let users communicate over great distances over a unified network. Trunking systemsĪ trunking system is like a mobile network for walkie-talkies. For example, Large construction sites, parks or heavily urbanized areas are places where a repeater would be necessary. Having a repeater allows for a strong signal in environments where there are multiple obstructions. RepeatersĪ repeater extends the range of a radio by boosting the signal. In the early days when most two-way radio communication used Morse code (radiotelegraph), operators used very short procedural signals to save time. Therefore, in this jargon buster, we can explain some of those frequently used terms by two-way radio manufacturers. Walkie talkie lingo can be difficult to understand for first time users. comes with highly sophisticated features that can often be difficult to understand for first time users.
