ECC Form 442 Exhibit No. 1 Page 1 of 1 Response to Item 9 9(a)— This research project involves experimenting with a‘~ 45° polarization transmitting antenna for the applicant‘s B—band cellular operation. FCC rules currently specify only vertical (90°) transmit antenna orientation for cellular base station transmitters. Cellular mobile stations typically operate with a 45° polarization, since most are using handheld subscriber sets that, (when held to the user‘s ear) are effectively at a 45° antenna orientation. The applicant would like to demonstrate the benefit of 45° polarization such as reduced transmitter power requirements for Code Division Multiple Access (CDMA) . 9(b)— Empirical measurement of radio frequency performance will be required for this project to determine benefit of 45"polarization. 9(c)— No cellular transmitting facilities in the applicant‘s service area currently operate with 45° polarization.
