Additionally, ANMS enables more precise hand-offs with fewer gaps in coverage because adjustments on multiple antennas can be made simultaneously. Previously, in Andrew?s opinion, clear trade-offs were needed even when individual cell sites or sectors were optimised. Now, whole networks can be adjusted simultaneously, records can be made, and analysis can lead to additional changes in much shorter intervals. The Windows(r)-based ANMS software communicates through a customer-supported Ethernet connection located at the base transceiver station or a wireless supported connection provided by Andrew. The secure virtual private network link is directed through the Teletilt(r) ATC200-1000 local rack-mounted controller installed at the base transceiver station to the operational maintenance centre, where an administrator will facilitate initial set-up rights to the end user and send them out through a secure VPN to any location with Internet connection. The new system is claimed to optimise radio frequency coverage by enabling antennas to be adjusted remotely without needing to put the entire cell site out of service or sending a crew to adjust the antennas. Operators quickly can adjust antennas to accommodate short-term changes in customer usage along specific sites in the network, such as high demand along urban highways during rush hour or during heavily-attended stadium events.
ANMS will be featured at Andrew's stand (Hall 1, Stand D08-D09) February 13-16, 2006 at 3GSM World Congress in
