The most important regulatory aspect of WiMAX is the availability and subsequent use of spectrum (a frequency band on which the service provider will broadcast on). Unlicensed spectrum allows any one to broadcast on that frequency within certain power limits. Licensed spectrum protects the broadcaster by giving them exclusive right to broad-cast on that frequency (spectrum). Other broadcasters who interfere with that frequency are subject to governmental sanction. Licensed spectrum can be obtained directly through a national government (Federal Communications Commission in the US, for example) or via a sub lease from someone who has obtained spectrum from the national government (this varies from country to country). Spectrum is often allocated by location and frequency.

Municipal Wireless Networks

Many cities throughout the world have launched their own wireless (usually Wi-Fi) net-works. Most of these networks were initially deployed as a convenience to citizens and in some cases as an effort to narrow the digital divide. Many cities have also found great cost savings on their own internal telecommunications and manpower costs by deploying municipal wireless networks. Ultimately, many municipalities may find that internet access is similar to the access to businesses and places of work provided by public roads, streets and sidewalks. In addition, telecommuters pose a lower support cost for local governments in that they don't put wear and tear on roads and other infrastructure. Given potential savings to taxpayers and potential economic development benefits in deploying such wireless networks, municipalities will be a leading market for WiMAX deployments.
