Those seeking the ultimate in wireless LAN speed will want to investigate the 2X mode from Proxim

Corporation, which increases the distance/performance ratio. Although not officially specified in the 802.11a

standard, 2X mode allows up to 108 Mbps connections.

802.11a—thirteen times the capacity of 802.11b networks.

Along with connection speed, capacity is the determining quality that can either inhibit or enable increased

productivity. More capacity allows more users to access the power of network computing, i.e., access to

databases, enterprise applications, and inter-activity with coworkers, wherever and whenever that power is

needed. There is, however, a distinct difference between 802.11a and 802.11b in their ability to deliver

network capacity via wireless.

802.11a is Faster than 802.11b at any Distance

The ideal wireless network consists of neighboring access points that operate on different channels. Using

different channels allows workers to connect to the network without experiencing interference from other users

or an unacceptable dilution of data rates. The greater the number of channels a network has, the less likely these

problems will occur.

This is why it is difficult to scale an 802.11b wireless network because the 802.11b standard only has three

channels. This means that, in a large deployment, it is likely that at least one access point with a competing

channel will be installed next to another. This is especially problematic with networks in multi-story buildings

because wireless signals radiate in all directions, not just horizontally.
