Radio networks include all wirelessly operating networks. A certain classification of the radio networks is possible on the basis of the range. The wireless LANs used in the local area belong to the group with the shortest range. These are those specified by IEEE under 802.11, but also the short-range networks such as Bluetooth, ZigBee, Nanonet and the WPANs.
As with the wired networks, there are also radio networks for the connection area. These networks include the broadband wireless networks standardized under IEEE 802.16 and 802.20: Broadband Wireless Access( BWA) and Mobile Broadband Wireless Access( MBWA). In addition, the UMTS-baseduplink and downlink technologies High Speed Downlink Packet Access( HSDPA) and High Speed Uplink Packet Access( HSUPA).
The transition to mobile radio networks is relatively smooth. These radio networks include all networks used in mobile communications, from trunked radio networks and company radio networks to mobile radio networks with GSM networks with General Packet Radio Service( GPRS), High Speed Circuit Switched Data( HSCSD), EDGE, UMTS and Long Term Evolution ( LTE).
