Abstract	Spread spectrum microwave radio has become an increasingly popular choice for wireless full-duplex T1/E1 access. Primary applications include cellular site interconnect, local area network (LAN) extension, private branch exchange (PBX) extension, wireless local loop (WLL), private networks (such as utilities, transportation, government, etc.), and "last mile" connections. In the United States, spread spectrum radios that operate in the industrial, scientific and medical (ISM) bands provide the user with the unique benefit of being "license-free" (not requiring any FCC licensing or coordination). The license-free feature makes spread spectrum radios a valuable alternative to leased lines and/or traditional microwave radio, due to fast implementation and low cost. The demand for full-duplex T1/E1 services has risen sharply with the advent of cellular, personal communication services (PCS), Internet access and other communications technologies. Most regional Bell operating companies (RBOCs), or alternatively, national telephone carriers, in the case of international markets, are not able to meet the scheduling demands for leased T1/E1 services. Also, competitive local exchange carriers (CLECs) and Internet service providers (ISPs) are attempting to capture a portion of this market. Due to the growing acceptance of spread spectrum as a permanent solution for these applications, the RBOCs, CLECs, ISPs, cellular/PCS operators and other customers are placing increasing demands for improved performance and enhanced features.
