Andy:You must not be getting ad $$ from Tropos.

It is about time someone in the analyst community exposes Tropos for what they are. A great 1st Generation single radio Mesh (Access and Backhaul with one 2.4Ghz radio)product that tried to do something it could not do with their single radio design.It cannot provide adequate throughput and will always be handicapped by latency related issues due to its poor backhaul performance between nodes.
Earthlink has know this limitation all along and it is beyond me as to why they have not bit the bullet and change to the latest Carrier Grade 4 & 6 Radio Mesh systems being installed in Boston suburbs (Strix) and Mpls Mn. (BelAir). These are and will be Carrier Grade Networks and will prove the Mesh concept. The Strix product is priced competively to the Tropos.
My concern as a service provider committed to the deployment of Mesh systems is that failure of Tropos based networks around the country to deliver on even the most basic level of Broadband (512Kbps is not Broadband) services. Latest I heard about is the Philadelphia network design going from an initial 20 Node/Sq Mile design to a 42Nodes/Sq Mile. I am sure they spin this as better coverage.
My concern: This has and will continue to open the door for the new WiMAX (especially when 700Mhz comes on line)and the Narrowband (512-768Kbps) Cell Nets to come in and replace these poorly designed networks.

Some one also needs to address the problems these 2.5Ghz WiMAX networks will have with Foliage blocking signal issues in many cities and in most all rural markets, especially while mobile.
WiMAX will shine when and if providers gain access to (spectrum)and deploy the 700Mhz based systems using WiMAX feature sets.
