Not only does that resolve any system conflicts on a campus (let’s say the engineering department uses 802.11a,
but marketing uses 802.11b), it also allows users with home wireless LANs (typically using 802.11b) to connect
to their wireless LAN at work (using high-speed 802.11a). It also means universal compatibility for public hot
spot users. Users with dual-mode cards can connect to wireless LANs wherever they go.
The bottom line is that 802.11a not only allows greater speed and capacity, but because it is backwards
compatible with existing 802.11b systems, 802.11a protects the technology investment in existing WLANs.
Harmony 802.11a—the best enterprise solution
on the market.
Though, like 802.11b, 802.11a is a worldwide standard, not all 11a solutions are equal. There are differences
in security, distance, and functionality that can affect the choice of a particular solution. Harmony 802.11a is
the leading enterprise solution available today and has important advantages over its competitors.
“We consider Proxim’s Harmony the most appropriate 11a access point for deployment in the
enterprise…Harmony’s transmission range far exceeded that of its rivals…Proxim’s two-tier hard-
ware architecture uses clusters of access points connected to APCs (Access Point Controllers). This
design is unique in the WLAN industry and allows for centralized configuration and management
of both 11a and hybrid 11a/11b/OpenAir networks while enhancing roaming capabilities.”

Harmony 802.11a—industrial strength privacy and authentication.
Security issues—privacy, authentication, and data integrity—are more important today than ever. A wireless
LAN that does not adequately address these issues is an open door to the enterprise. Fortunately, 802.11a is
easily configured to provide optimum security.
Network administrators using 802.11a have all of the most advanced data encryption and authentication
techniques at their disposal in order to secure the network. Systems from Proxim Corporation are noteworthy
for their enterprise-class security advantages. Passive eavesdropping and brute force attacks due to weaknesses
in Wired Equivalent Privacy (WEP) are blocked. And unauthorized network access, a problem for systems
using MAC addresses for access control, is foiled.
