An outdoor antenna can be used to solve issues with multipath reflections. <br />Satellite television is transmitted in the K, Band of radio frequency and is not very susceptible to <br />corona generated noise. <br />Line of sight for satellite television users could be obstructed by a transmission line structure. Line <br />of sight can usually be restored by moving the consumer satellite dish to a slightly different location. <br />Internet and Cellular Phones <br />Wireless internet and cellular phones use frequencies in the ultra-high frequency (UHF) range. The <br />specific UHF frequency used by a cellular phone would depend on the technology (global system for <br />mobile communications (GSM), 3G, etc.) of the provider. All radio frequencies used for both <br />cellular phones and wireless internet are high enough that the effect of corona generated noise near <br />the line would be negligible, no impacts are anticipated. <br />GPS -Based Navigation Systems <br />Corona -generated noise and not the EMF from transmission lines could be a source of <br />interference for GPS systems. Satellite GPS signals are broadcast at 1.57542 GHz (L1 signal) and <br />1.2276 GHz (L2 signal) and are high enough that they would have minimal interference. <br />Differential correction signal beacons on the nationwide Coast Guard network transmit at <br />frequencies around 283-325 kHz and are susceptible to electrical noise. Interference with correction <br />signals could result in reduced accuracy while operating directly under a high-voltage transmission <br />line. <br />Impacts to GPS systems are typically an issue in agricultural areas because of concerns with <br />interference with farm machinery. The Project is not located in an agricultural area and no impacts <br />with GPS systems are anticipated. <br />Environmental Assessment <br />PUC Docket E002/TL-11-223 Page 53 <br />
