Matt,

A multi-band mesh node does the backhaul on 5 GHz (sometimes with more than one 5 GHz radio). This reduces (but certainly doesn't eliminate) the 2.4 GHz self-interference and other-network-interference level.

The reason the big muni projects often select Tropos is that Tropos has the best marketing effort out there and has been "in the game" longer than most other mesh equipment vendors.

I predict it won't take too may big Tropos-based muni networks to fail before future big-city muni administrators will "see the light" and chose other, more throughput-capable mesh vendors.

In recent post I explained that here in Atlanta you can only use a single 2.4 channel because of the noise floor. How is a multi-band mesh node going to work?

Maybe there is a reason the big muni projects keep selecting Tropos.

Dawn,

Thanks for posting the St. Cloud PepLink and HP info.

Using standard CPE (PePLink)is very good but using Tropos nodes is very, very bad. Very bad because they only have one single 2.4 GHz radio so after 2 or 3 hops, all the throughput capability is gone not to mention that the interference level from having all the access and backhaul packets colliding on 2.4 GHz (along with any WISP and other 2.4 GHz network packets) will slow all the networks (muni and WISP) down further. I hate to "finger" anyone but Tropos' stubborn refusal or inability (anyone at Tropos listening???) to produce a 2-band mesh node is going to doom them to failure along with any big city that deploys their nodes without an extremely efficient point-to-multipoint backbone design on 5 GHz.

PePLink announces as the official Citywide Wireless CPE provider for City of St. Cloud in Florida *

*Hong Kong, Mar 7, 2006 - *PePLink, a leader in citywide WiFi wireless broadband devices today announced the City of St. Cloud, FL, a suburb of Orlando, has chosen PePLink to be the official wireless CPE provider for the Cyber Spot, the City's 100% free citywide high-speed wireless Internet service.

With a reliable, secure, ease of use wireless CPE - PePLink Surf, every citizen or business in the city of St. Cloud can connect to the citywide wireless network at a high speed. The CPE greatly enhances the throughput and reliability of both up and down link compared with a wireless-enabled computer desktop or notebook computer.

The simple true plug and play nature of the PePLink Surf helps the citizens in St. Cloud to bring the wireless signal indoors with ease. At the same time, the PePLink Surf units can be remotely managed, monitored and provisioned by PePLink's carrier-grade management and reporting solution, PCMS (or PePLink Centralized Management System). This can ensure a scalable and rapid rollout of the wireless systems within a short period of time. This eliminates an onsite installation charge.

"Being chosen by City of St. Cloud has further endorsed our capability to offer reliable wireless solutions to municipal wireless networks built with mesh network technology," said Alex Chan, Managing Director of PePLink. "PePLink Surf together with PCMS is the complete solution specifically designed for today's citywide wireless networks."

PePLink Surf series consists of Surf 200BG and Surf 400BG. For more information on PePLink Surf series, please visit http://www.peplink.com <http://www.peplink.com/>.

The city is selling "signal boosters" (I read that as amps) to anyone that wants them for $170?

Oh man, this deployment is gonna come CRASHING down.  Hard.

It's really too bad these people are too ignorant, stubborn or just plain stupid to call any of us in to help.

sigh

I am not a fan of muni wireless.
