_ Radio relay (mesh) networks are gathering momentum• many are based on 802.11 radio technology and therefore have a low cost base• back-haul is considerably less than for conventional cellular
WLAN access points
Fixed ‘seed’ nodes
User terminals
Infrastructure mesh:
Relaying between access points only These links are static or slowly changing
Mobile mesh:
Relaying between all devices with fast dynamic routing
Ad-hock and sensor networks

Ülesanne 1Signaali kodeerimiseks kasutatakse ühtlast
IKM kooderit. Kooder peab tagama dünaamilise diapasooni 30 dB. Nõutav signaal-kvantimismüra suhe on 26 dB. Diskreetimissagedus on 8 kHz. Leida bitivoo kiirus kooderi väljundis.
