TIA/EIA 97 F (January 2005): "4.2.1.1.3 ... For all base stations the pilot time alignment error should be less than 3 µs and shall be less than 10 µs.... 4.1.2.3 ... For all operating temperatures specified by the manufacturer, the average frequency difference between the actual CDMA transmit carrier frequency and specified CDMA transmit frequency assignment shall be less than ±5^10-8 of the frequency assignment (±0.05 ppm)." _______________________________________________ time-nuts mailing list [email protected] https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts
