Rozwój sieci bezprzewodowych
Obecny trend: unifikacji sieci i usług:
• Sieci komórkowe nowych generacji:
B3G (Beyong Third Generadon), LTE (Long Term Evolution)

• Lokalne mobilne sieci bezprzewodowe
(mobile IP networks, mobile ad-boc networks, vebicular ad-boc networks)
• Hybrid broadcast and cellular networks, m.in. standard DVB-H
Inne koncepcje:
• Sieci sensorowe ( Wireless Sensor Networks)
- systemy malutkich czujników zbierających dane o otoczeniu i przekazujących je drogą radiową do centrum kontrolnego
• Systemy UWB (Ultra WideBand)
- transmisja danych na niewielkie odległości (pojedyncze metry), wewnątrz budynków, w szerokim paśmie częstotliwości (3.1 -10.6 GHz)
