Abstract :
The factors which affect the choice of the LuckyNet radio link design, involving data rates on the order of 2.5 Gb/s, are discussed. The specific design of the 2.5-Gb/s radio link for the 23-mile path between the Murray Hill and Crawford Hill locations of AT&T Bell Laboratories is described, along with preliminary performance results. The propagation factors which have the dominant effect on link availability are fading due to rain, water vapor, and multipath. Less than 10-11 bit error rate (BER) is achieved with an estimated availability of about 95%/yr. The link provides 2.5 b/s/Hz of bandwidth by using dual polarization and QPSK modulation
