(English Abstract)
The mobile service was focused on voice and low rate data service. But recently high data rate service is getting more important, so mobile service operators are providing 1x EV-DO services for high data rate service. Many mobile repeaters were deployed for service coverage, but most of them were deployed when voice and low rate data service were main service. It is necessary to test whether these repeaters are suitable for 1x EV-DO networks for high rate data services. In field test, 1x EV-DO data rates were measured through various repeaters. Some repeaters showed data rates degradation compared with 1x EV-DO AN. The specifications of the repeaters were analyzed. And under the various radio environments such as fading and RSSI, data rates through repeater were tested. These test results will be useful for operation guide of repeaters in high data rate service networks.
