Abstract

Oppfinnelsen angår et pakke-radiosystem og en fremgangsmåte for å benytte SDMA for kanaletablering. Pakke-radiosystemet omfatter en nettverksdel (100), minsten abonnentterminal (102) og en dupleks- radioforbindelse (104) mellom nettverksdelen (100) og en abonnentterminal (102). Dupleks-radioforbindelsen (104) benyttes for oppsetting av forbindelse og pakkeoverføring. Oppfinnelsen kjennetegnes ved at for oppsetting av forbindelse er nettverksdelen (100) og abonnentterminalen (102) innrettet fora etablere en spesiell kanal (210) med betraktelig lengere rekkevidde enn en normal kanals (200) rekkevidde. Den spesielle kanalen (210) har et bitenergi/støy-forhold som er omkring 5 -12 dB bedre enn den normale kanalens (200).The invention relates to a packet radio system and a method for using SDMA for channel establishment. The packet radio system comprises a network portion (100), at least subscriber terminal (102), and a duplex radio connection (104) between the network portion (100) and a subscriber terminal (102). The duplex radio connection (104) is used for setting up connection and packet transmission. The invention is characterized in that for setting up a connection, the network part (100) and the subscriber terminal (102) are arranged forums to establish a special channel (210) with a considerably longer range than a normal channel (200) range. The special channel (210) has a bit energy / noise ratio that is about 5-12 dB better than that of the normal channel (200).
