3e–527A3 Wireless Access Point – 8 Port
802.11a Turbo
802.11a Turbo technology provides speed and throughput of more
than double standard wireless LAN technologies in networking products
such as PCs, access points, routers and PC cards. It is very helpful to users
who require additional bandwidth (over standard WLAN technologies)
that results in higher throughput necessary for a variety of functions such
as: streaming media (video, DVD, MPEG), VoIP, etc., or for providing
multiple users on a single WLAN with optimal speeds despite network
demand.
108 Mbps is the maximum link speed available and the typical MAXI-
MUM end-user throughput ranges from approximately 40 Mbps to 60+
Mbps, depending on application demand and network environment.
NOTE: Turbo A's channel bonding feature can significantly degrade
the performance of neighboring 802.11a channel WLANs that don't use
Turbo A, because there isn't enough room in the 5GHz wireless LAN
spectrum for the increased spectrum used by channel bonding. Moreover,
Turbo A doesn't check to see if 11a standard-compliant devices are in
range before using its non-standard techniques.
The encryption must be applied in the 3e-527C, however, the CPU
power can not encrypt more than 12 Mpbs of data. Therefore, even in
turbo A mode, you will not see more than 12 Mbps of throughput. One
benefit of Turbo A is that it provides better RF range.
Network Configuration
The 3e–527A3 is an access point/gateway with bridging capability:
• Access point/Gateway plus:
• Wireless bridging with choice of:
- Point-to-point setup
- Point-to-multipoint setup
- Repeater setup
Bridging actually has more choices, but the above choices are popular
and are discussed later in this user guide (Chapter 4).
