Wireless Internet Technology!!!

Wireless Internet Technology!!!

Wireless Internet Technology!!!

(OP)
Hi,

I am trying to determine the best technology for wireless internet. I searched the internet and found a product by Motorola called "CANOPY". And onther technology developed by Intel which is "WiMax".

If anyone have any experience using any of these systems, please I need your advice.

I am trying to install this system in the middle-east!

Thanks for your inputs

RE: Wireless Internet Technology!!!

What crieria are you using to determine "best"?

I am looking for a system that is:

*Relaible
*Cost effective
*Eazy to built & mentain
*Wide coverage(for a hole City no a HotSpot)

RE: Wireless Internet Technology!!!

Wimax is specifically designed to cover large areas, and serve as a 'last mile' connection.  Wimax currently comes in 2 'flavors':  802.16-2004 which is for fixed subscriber stations, and 802.16e which is for mobile subscribers.  The currently available Wimax parts are built to 802.16-2004.  Mobile Wimax (802.16e) was ratified by IEEE in December 2005 and parts may finish interoperability testing in ~6 months.

Also, while Wimax is designed to cover large areas, in heavily populated areas you will inevitably use up your data bandwidth very quickly.

Some companies to look at for Wimax are:  Alvarion, Red Line Comms, and Aperto Networks.  Also, check out www.wimax.com, and if you're in the mood for some light reading the IEEE 802.16-2004 specification is available for free at http://standards.ieee.org/getieee802/portfolio.html.  802.16e will be available for free at the same site 5 months from now.

I thought that the two flavors of WiMax are: 'Really Soon Now' & 'Almost Here'.

How will the teeny (100's of mWatts) transmitters on the PC's going to transmit their signals all the way back to the MAN?

Wheels within wheels / In a spiral array
A pattern so grand / And complex
Time after time / We lose sight of the way
Our causes can't see / Their effects.

RE: Wireless Internet Technology!!!

Carriers can implement the standard in different ways, but it is possible in the standard to use different modulations on each direction of the link.  So there might be say 64QAM on the downlink and QPSK at a reduced data rate on the uplink extend the uplink range.  WiFi can also scale the data rates, but I believe (correct me if I'm wrong) that the uplink/downlink must both use the same data rate/modulation.
