I'm not going to get into an enormous amount of detail, but I know a well-known licensed 2.5ghz NLOS provider, has a maximum NLOS range around their towers of about 3-4 miles (with indoor units). That said, the Sprint-Nextel spectrum is very unlikely to be available on independent lease, and you would be better off contacting whoever is a non-profit or educational licensee in your coverage area for spectrum access.
Also, don't discount 2.3ghz, you may be in a coverage area where WCS is available. 4.9ghz is okay but I haven't seen a lot of case studies showing where it penetrates trees compared to 2.5/2.3ghz licensed. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Felix A. Lopez Sent: Thursday, June 21, 2007 9:24 PM To: WISPA General List Subject: RE: [WISPA] Call to Vendors..... Blair/Chris: I worked with my local WISP whose been in the business a long time and loved helping them to build their business. We installed a combination mobile mesh/fixed wireless system using equipment from a major manufacturer and provided the following: Wireless Mobile mesh network with the 4.9 GHz license Electric utility metering using the 2.4 GHz (WiFi) in a Point to Point and Point to MultiPoint. The fleet manager will eventually have the modem and mobile server installed in each truck. The utilility meters used a 2.4 Ghz chipset but we had to select the best channel out of 1-13 channels and locked in SSID at Channel 5 after RF spectum analysis (which really means we walked around with a sniffer). There are other "mobile modems" that you can utilize. I can hardly wait for the new WiMax 802.16(e)/WiFi 802.11(n) Intel Montevina (Centrino) platform to arrive. But of course that means you need a 2.5 GHz license. But as one reader posted I think Sprint may be eager to work with someone on a lease basis to build the business case. I hesitate to mention any manufacturers for fairness. With that being said IMHO it can be designed, commissioned and installed with good RF Planning. I prefer and my field advice is to identify and work through a VAR, channel partner or disributor type VAR who can give you personalized service. Some WISP may have that capability. I built my local WISP into a solutions provider and certified on Mesh.
