Wireless routing (mesh) networks provide robust wireless coverage through their unique architecture. Every device serves as both an access point and part of the network infrastructure, automatically forwarding traffic for other devices. This allows the network to:
1. Self-configure into a microcellular structure, dramatically decreasing needed link distances and increasing scalability.
2. Automatically select the best RF links and multihop routes based on current propagation conditions, taking advantage of the best paths rather than needing to overcome the worst cases.
As more devices are added to a wireless routing network, the probability that a new subscriber will have coverage increases exponentially. This ensures full and continuous coverage at lower overall cost compared to traditional point-to-multipoint networks.

5. High Transmit Power Radios
Indoor access points are limited to 100 mWatts
compared to outdoor units that are allowed to
transmit as high as 1 watt. The FCC has recognized
that outdoor networks require increased power levels
in order for access points to effectively support
backhaul links over increased distances. Higher radio
transmit power enables stronger client connections
and stronger mesh connections, which result in more
consistent and faster data speeds. An access point
with a transmit power of 100 mWatts (20 dBm) will
offer only 10 percent of the power of an access point
with a transmit power of 1 watt (30 dBm). Lower
power access points can require two to four times

Figures 3 and 4 show relative coverage for 802.11g and Motorola’s outdoor 802.11n solution. The dark areas
in the coverage map depict areas with no usable signal strength. Even when legacy 802.11g access points
are deployed closer to each other, some areas are left with no coverage. Network designs completed with
sophisticated planning tools, such as Motorola’s One Point Wireless Suite, reveal that 802.11g systems require
52 percent more access points to cover the same area compared to Motorola’s outdoor 802.11n technology.
