Network Radios
Network Radios are a relatively new development that provide easy to operate simplex communications with no licensing requirements. Anyone can purchase and use network radio hardware without training or examinations.
There are several manufacturers producing a growing range of network radios for use at home, in vehicles and for handheld portable use. Global communication between network radios is achieved through mobile telephone network infrastructure.
Network Radio devices operate by transmitting and receiving low power radio frequency energy propagated through free space to connect to RF equipment at 'cell towers' using GSM/2G/3G/4G modes/protocols.
Network radios (and mobile telephones) communicate with the cell-towers operating on several allocated bands including 700MHz, 800MHz, 900MHz, 1800MHz, 2100MHz and 2600MHz The specific band used depends on the device in use and network coverage at current location. The network radio deals with mode, frequency and band switching automatically as propagation conditions change.
Network radios are 'license exempt radio communications equipment' as the end user does not require a license to operate these devices, the bands of radio spectrum used are licensed to the network infrastructure owners/network operators.
Although You will hear some people stating that network radios are 'not real radio' they are indeed mistaken.
It is correct to state that Network Radios are not 'HAM radios' as they do not operate on allocated licensed amateur 'HAM' frequencies and fall outside the scope of Amateur Radio licensing.
Many business and commercial organisations have been using network radio equipment for years with proprietary firmware/software.
There are growing numbers of unlicensed radio enthusiasts and licensed amateur radio operators using network radio devices, mobile phones, laptops, home PCs, tablets, netbooks etc with Apps like the free Personal version of Zello PTT and the ZelloWork system (the commercial version of Zello) to communicate around the world with ease and clarity.
