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 /> 1 <br /> 1 <br /> i <br /> Environmental Assessment <br /> PUC Docket E002/TL-11-223 Page 53 <br />
