| How will he acquire the spectrum? I thought Wimax operates on licensed frequencies, and those frequencies were purchased recently at auction. How will he be able to build a Wimax network?

Mark The city may already have spectrum for use by police & city government. Some of that spectrum may be usable by a Wimax system.

He plans to use other types of city assets, such as an existing base station at City Hall with which he plans to demonstrate the system's capabilities, which would cover six miles in downtown Delray Beach. »en.wikipedia.org/wiki/WiMAX#Spec···n_issues
The 802.16 specification applies across a wide swath of the RF spectrum, and WiMAX could function on any frequency below 66 GHz.
There is no uniform global licensed spectrum for WiMAX, although the WiMAX Forum has published three licensed spectrum profiles: 2.3 GHz, 2.5 GHz and 3.5 GHz.
In the unlicensed band, 5.x GHz is the approved profile. Telecom companies are unlikely to use this spectrum widely other than for backhaul, as they do not own and control the spectrum.
It is possible to run Wimax on spectrum outside of that just auctioned by the FCC.

Does this mean anyone, including individual home owners will be able to use Wimax in an unlicensed band, If someone sells Wimax access points? That seems like it would be problematic because Wimax uses more transmit power. The range is two miles? It seems like people would clobber each other.

That seems like it would be problematic because Wimax uses more transmit power. The range is two miles? It seems like people would clobber each other. Mark The trick would be to find vendors to sell equipment that works in the desired frequency bands. They won't make hardware that will work on just any frequency. That is why the licensed bands will be the main sales for Wimax hardware vendors. Though for a contract, they may make the hardware work for other frequencies than the licensed ones. And that is where cities could cut special deals.

He need only apply for the FCC 3.65Ghz (special feature spectrum) which is a License Spectrum the FCC has set aside for just such a deployment. It is free to anyone registering for the spectrum and allows multiple providers to operate in the spectrum after they have registered their Radio/Tower SIte and end points. This way the FCC will assure each that they will not interfere with each other in any given space.
He need only focus on deploying a Fixed (PTP) and portable service (mobile is more difficult in this space) and avoid any heavy foliage areas if this is to be successful.

What is "x" in 5.x? "In the unlicensed band, 5.x GHz is the approved profile."
Not very specific. We already use 5.2/3 and 5.7/8 for 802.11, so what is "x" above for WiMax? |
