Some Wireless History – Remember the NII?
In 1995, Dewayne Hendricks wrote a paper, Spread Spectrum and the Amateur Radio Service (1995), that was very forward looking. In it he reviews a good deal of early history, for example:
Since the Broscius article in 1989, there has been a lot of activity in the commercial sector regarding SS. As a result of the request and feedback of many manufacturer’s of Part 15 devices, the FCC changed the rules in 1990 in order to make it possible to product devices under Part 15 which could operate at higher data rates and to close up some of the holes in the previous version of the regulation that had been issued in 1985.
In January, 1991, Apple Computer filed the now famous Data-PCS petition with the FCC which asked for the allocation of 40 MHz in the 1850-1990 MHz band for a new radio service to be used for high-speed, local area network services. Some important points of the petition include:
* be accessible to users of personal computers without imposition of licensing obligations, network connection fees, or air-time charges;
* be open to any computer manufacturer’s products and any network access and usage scheme that complies with the regulatory requirements.
* be regulated in a manner that assures non-discriminatory access to assigned frequencies by compatible devices for like purposed; and
* Have flexibility built into the initial regulatory scheme to encourage innovation in and the evolution of Data-PCS technologies and services.
