Wireless subscriber access equipment: certification procedure

The paper describes two types of equipment for the radio access of users. They are point-to-multipoint equipment and WLL equipment. The first type of equipment is designed for servicing groups of users who are dispersed over large territories. The second type should service a significant number of single and scanty groups, which are situated on a limited territory with a sufficiently large density of population. To provide multistational access, the following technologies are used: FDMA, TDMA and CDMA. The paper briefly describes these technologies and outlines the certification procedure for this equipment.
