Many times I've been asked to prove a regulation I swore happened. It was the one stating that once a radio manufacturer certifies a radio with an antenna of x gain, antennas with lower gain, but a similiar pattern and gain characteristics can be used without certification.
On various lists I have been basically laughed at. Well, I found a reference to it today, so I tracked it down. Here is the text of the R&O in question: 8. In order to support more flexible antenna requirements for unlicensed devices, the Commission proposed to allow that devices be authorized for use with multiple antennas. Although the Commission proposed to modify Sec. 15.203 to implement the modifications, it believes that the changes are better suited for Sec. 15.204. Accordingly, the Commission modifies Sec. 15.204 to permit intentional radiators to be authorized with multiple antennas of similar in and out-of-band gain and radiation pattern. Compliance testing for the intentional radiator must be performed using the highest gain antenna that will be used with the device. The manufacturer must supply a list of other acceptable antennas in the literature delivered to the customer. http://frwebgate.access.gpo.gov/cgi-bin/multidb.cgi?WAISdbName=2004_register+Federal+Register%2C+Volume+69+%282004%29&WAISqueryRule=%28%22page+54027%22%29&WAIStemplate=multidb_results.html&WrapperTemplate=aces140_wrapper.html&WAISqueryString=%22page+54027%22&WAISmaxHits=40 http://frwebgate2.access.gpo.gov/cgi-bin/waisgate.cgi?WAISdocID=949617394663+1+0+0&WAISaction=retrieve http://frwebgate2.access.gpo.gov/cgi-bin/waisgate.cgi?WAISdocID=949617394663+1+1+0&WAISaction=retrieve http://frwebgate2.access.gpo.gov/cgi-bin/waisgate.cgi?WAISdocID=949617394663+1+2+0&WAISaction=retrieve ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com -------------------------------------------------------------------------------- ** Join us at the WISPA Reception at 6:30 PM on October the 16th 2007 at ISPCON ** ** ISPCON Fall 2007 - October 16-18 - San Jose, CA www.ispcon.com ** ** THE INTERNET INDUSTRY EVENT ** ** FREE Exhibits and Events Pass available until August 31 ** ** Use Customer Code WSEMF7 when you register online at http://www.ispcon.com/register.php ** -------------------------------------------------------------------------------- WISPA Wants You!
