The main advantage of radio communication is its independence. There are mostly used licensed frequencies, i.e. dedicated radio channel is private and its purity is guaranteed by government body. Communication distance is depended on RF power, antennas and their high above the ground and the next factors, however it is in tens of km, direct line-of-sight
is not required. The user has got everything under his control. From technical point of view radio network has got very fast response time
with a minimal jitter.
When there are a long distances among sites and GPRS/EDGE/UMTS network covers the territory, GPRS/EDGE/UMTS router is possible to use. However essential characters is necessary to keep in mind: public service, technical features are not guaranteed. On the other hand GPRS/EDGE/UMTS networks have got higher throughput

Radio modem
Radio modems transfer data wirelessly across a range of up to tens of kilometres.Using radio modems is a modern way to create Private Radio Networks . Private radio networks are used in industrial critical applications, when real-time data communication is needed. Also Radio Data Modem enables user...
