Abstract :
“Radio in the Local Loop” for ATM transmission is expected to become economically important if transmission channels prove to be sufficiently well behaved. Using a PRBS channel sounder we have measured channel impulse responses at 29.940 GHz with a 5 ns temporal resolution for distances up to 3.8 km. We have further investigated the influence of polarization on fading and delay spread. Results obtained so far suggest “Radio in the Local Loop” should support ATM transmission over distances of a few hundred meters, but fading caused by multipath propagation may cause severe problems at larger distances along streets with heavy traffic load
