What is IEEE 802.11b Wireless LAN(WLAN) technology?

• When you already have a large investment in 802.11b devices:

The relatively high costs associated with migrating from a large-scale 802.11b system to 802.11a will be difficult to sell to the company's financial decision makers.

• When End users are sparsely populated:

If there are relatively few end users that need to roam throughout the entire facility, then 802.11b will likely meet performance requirements because there are fewer end users competing for each access point's total throughput. Unless there are significant needs for very high performance per end user, then 802.11a would probably be overkill in this situation.
