coverage at comparable performance. Future expectation is that wireless WAN will reach tens
of Mbps and WLAN will be blazing at many Gbps.
It is easy to get mesmerized by the throughput numbers of the wireless technologies, but factors
such as air-link efficiency, radio access network latency, and capital and operational cost vary
among them. Each technology has its strengths and weaknesses in terms of coverage area, cost,
bandwidth, latency, and supported speed of movement. Maximizing the wireless data
experience requires situational usage. Therefore, it is wise to have a mobility infrastructure that
keeps up with the ...
