Hi,
802.11a specifies 54Mbps, but is easily capable of 108Mbps with some
modulation modifications. This is probably the technology behind the Proxim
wireless LAN AP. It's a similar story to the 22Mbps access points that were
floating around a few years ago, which essentially extended the 802.11b
standard.
In terms of LEAP etc, it is important to understand that LEAP is an
authentication protocol used in an 802.1x/EAP framework. In other words,
LEAP is a specific EAP authentication mechanism, and EAP is open to using
any authentication mechanism. Here is a list of others that you'll see on
the WLAN:
1. EAP-TLS - uses server-side and client-side certificates for
authentication
2. EAP-TTLS - uses server-side certificate and any type of client-side
authentication (e.g. username/password, OTP). Server-side certificate is
used to authenticate access point/RADIUS server and then used to establish a
secure communications channel over which a second phase of authentication
(client-side authentication) occurs.
3. Protected EAP - almost identical to EAP-TTLS, except developed primarily
by Microsoft, as opposed to EAP-TTLS which was developed primarily by Funk
software. PEAP is most likely the successor to LEAP, as it is now supported
on Windows 2000 SP3 + Hotfix and Windows XP SP1. Windows 2000 RADIUS also
now supports PEAP. PEAP also provides domain login over the WLAN, provided
you are using Active Directory.
4. EAP-SIM - uses GSM SIM cards to provide authentication for public WLAN
access. This has a promising future in terms of the billing infrastrucuture
already in place around SIM cards.
Regards,
Justin

Hi Eric
Thanks for your help.
Are you talking about ths product.
http://www.proxim.com/about/pressroom/pressrelease/pr2001-10-08.html
What is the technology behind 100 Mbps wireless networking of Proxim.
Is it also available on Harmony AP ? I think AP supportteh data rate 54 Mbps
max.
Regards
Jotiram

There is a company called Proxim that makes a 100Mb WLAN AP, but again no
LEAP. They use proprietary security measures, which I'm not real sure
about. They even have a produce that they say can do 1Gbs for site to site
wireless solutions. It's actually something like 800Mb full duplex, but I
guess that is close enough for marketing.

Cisco is no longer the only player in enhanced security because of PEAP, a
standard in which other vendors, including Cisco, are now supporting.

No 100mb as of yet. Hell, 56mb just came out. It won't be too long.
LEAP is Cisco proprietary. Until the standard is ratified, they are the
only player of enhanced wireless security. I have not heard of any other
maker with any other form of LEAP.

Hi all
I appreciate if anyone know about
* 100 Mbps wireless LAN
* Access point using LEAP protocol other than Cisco Aironet.
Thanks in advance.
