Much of this book focuses on Wi-Fi, and Wi-Fi derived protocols (such as AirMAX, and the Canopy system). However, it is worth remembering that there are other options. Both WiMAX and LTE primarily target the cellular telephony market, but are available for Internet distribution as well. The primary disadvantage of both systems is cost: equipment for a WiMAX tower can easily cost $20,000 or more, and most vendors require a network core that can cost ten-times as much. The same is true for LTE: tower equipment is expensive, and an LTE “packet core” is prohibitively expensive to most deployments.
Both WiMAX and LTE are worth considering if you are looking for a high-density of deployments, can afford dedicated spectrum licenses, and have the funding for a very expensive initial build-out.« Chapter 2, Wireless Protocols Up To Contents Chapter 2: Channel Widths »
