Wireless router networks bypass the wired local loop with fast “always- on” wireless Internet access. The Nokia AIR™ Operating System (OS) provides intelligence, security and ease of use to make wireless networks practical, simple to deploy, and cost effective. Wireless Internet or intranet access across a network is completely transparent to the end user. - Page 8 1.1.2 Installation Components Each installation consists of a Nokia RoofTop™ Wireless Router, RF cabling, lightning protection, and an amplifier (optional). The antennas mount on the roof, or in a location in line of sight to other antennas in the network.
