Cisco told the FCC an allocation plan for 71-76 GHz and 81-86 GHz shouldn’t channelize that spectrum. Cisco told the FCC in a filing that licensees should be allowed to use bandwidths of less than 5 GHz in each…

direction and expand as their need for capacity grows. In June 2002, the FCC proposed rules for 71-76 GHz, 81-86 GHz and 92-95 GHz that would let commercial users and govt. and scientific operations co-exist. The proposed rules would cover fixed point-to-point operations in that spectrum, with the objective of promoting more spectrum sharing between federal and nonfederal users in the band. Cisco said its idea for 70 and 80 GHz is akin to that of a “spatial pipe,” or a radio link between 2 points that would allow users to use some or all of the spectrum for a single pair of radios or multiple pairs, using any modulation scheme. “By defining such ’spatial pipes’ and recognizing them flexibly, the Commission can enable manufacturers to meet the user’s needs as precisely and as cost-effectively as possible and to provide the maximum possible flexibility for growth,” Cisco said. Meanwhile, a committee of the Wireless Communications Assn. (WCA) recently submitted proposals to the FCC for technical rules for terrestrial fixed operations at 70 and 80 GHz. The WCA’s Above 60 GHz Committee urged the FCC to adopt the proposals quickly “so that the 70/80 GHz frequencies can be employed to bring the public low cost, fiber equivalent wireless broadband connections in the very near future.” The committee includes Cisco, Endwave, Harris, Loea Communications and Terabeam. Among the issues covered in the proposals were interference protection criteria, which commenters have told the FCC in the past would need to differ from those that apply in lower frequency microwave bands because of different radio frequency propagation effects. When comments were previously submitted to the FCC, consensus on this issue was elusive, the WCA panel said. It said its proposal reflected the fact that rain fading will be correlated in these frequencies, in that both the carrier and the interference will fade together in rainy conditions.
