Trapeze Unveils Next Gen Product

WiFi switching is back on the agenda this Monday with Trapeze Networks Inc. making bold claims for its new WLAN system, while broadband wireless grabs headlines as vendors introduce new gear ahead of the WiMax World show in Boston this week.

Trapeze Swings Again: WiFi switch startup Trapeze is back with a new architecture that it claims will offer the benefits of both centralized and stand-alone WiFi access points.

The Pleasonton, Calif.-based company calls the new architecture "Smart Mobile" and says it combines the benefits of centralized control and management with the efficiency of optimized traffic flows using "intelligent switching." Dan Simone, VP and chief technology officer at Trapeze Networks, says that this enables one system to support applications like fast device-to-device VOIP calls as well as separate guest access networks over the same system.

"We believe this is the right architecture for next generation wireless LANs," Simone tells Unstrung.

The system is different from many of the switching products out there today because it enables applications that require low latency -- such as voice over WLAN -- to be handled directly at the access points, enabling them to communicate directly in a peer-to-peer fashion without requiring round trips to the central controller. The company suggests that businesses could look at network deployments that handle voice at the AP but route data traffic back to the controller.

Simone says the firm will start shipping Smart Mobile later this month.

Fixing mobile WiMax: Ahead of the WiMax World show in Boston, smaller vendors are introducing new products that attempt to help operators move from fixed to mobile WiMax services. Unstrung will be at the show and reporting on the latest developments in the world of WiMax.

Airspan Networks Inc. (Nasdaq: AIRN) is showing off its new HiperMAX basestation portfolio, which will start shipping in the fourth quarter of 2006. The boxes have a software-defined radio (SDR), which Airspan says will make it simple for operators to update products in the field when they want to move to mobile.

The firm has also updated its standard and mini-base-stations with support for a boatload of new frequencies. Perhaps the most crucial update is due in 2007, when Airspan will add support for the 2.5GHZ to 2.7GHz bands.

These are the frequencies that operators like Clearwire LLC (Nasdaq: CLWR) and Sprint Corp. (NYSE: S) will employ for planned WiMax networks in the U.S.

Aperto's Burly Chassis: Aperto Networks Inc. has another take on how to move from fixed to mobile. The firm has updated its PacketMAX architecture with the PM5000 basestation, which enables operators to run fixed and mobile WiMax services side-by-side.

The PacketMax 5000 can be set-up with fixed WiMax blades, or with line cards supporting mobile WiMax, as such updates arrive on the market. The company says it will be important for operators to have options on which services to support as they plot initial WiMax networks.

re: Trapeze Unveils Next Gen Product So is this basically just one-arm on the AP? Where the caller hits the AP and connects to the another device on the same AP?

Sounds useful only when you're calling someone within your own vincinity.

re: Trapeze Unveils Next Gen Product Or maybe a voice-specific SSID that bridges the traffic locally, like a traditional AP and then a data SSID that backhauls the traffic. Can't image the APs are doing any ToS/diffserv tagging, call admission control or other intelligent features required for real voice deployments much less anything intelligent for converged devices. Unless, maybe, they are really FAT APs.

Alternative design would be to put switches closer to the edge if indeed the Trapeze switches are introducing jitter or a congestion point.

Would love to know what they are actually doing though as this could be interesting if implemented correctly.

re: Trapeze Unveils Next Gen Product From reading the release, an imperfect analogy could be the media gateway and softswitch architecture, where user plane traffic is switched locally, and control traffic is handled by the centralized server. In mobile phone networks this is sometimes called Gǣdistributed switchingGǥ.

If IGve understood correctly (thereGs a good chance I havenGt), this Trapeze initiative is similar in concept to what Colubris is doing with its multiservice controller.

See Colubris: Fat Is Back article from April 2005

"A local MAC is essential to do 802.11n -- a split MAC will fall flat on its face." claims Colubris's amusingly named CTO, Pierre Trudeau. The logic being that, as many vendors use systems that tunnel back to the switch, this will become a bottleneck as data gets faster on the edge.

And the same point was made years ago by CiscoGs Aironet group.
