A cellular telecommunications network base station repeater for a mobile terminal in a network having a power control function causes, during an active communication session, mobile terminal uplink transmit power to decrease in response to an increase in signal strength of the received uplink signal. The gain of the repeater is increased in response to an increase in the uplink signal received at the repeater above a threshold, and subsequently decreasing the gain until the measured power in the received uplink signal exceeds the threshold. Due to the power control function, increasing the gain causes the transmit power of the mobile terminal, and hence the uplink signal received at the repeater, to decrease. Decreasing the gain causes the transmit power, and hence the received uplink signal, to increase. The threshold not being exceeded is indicative of the communication no longer being active, and the repeater will eventually deactivate.

Base station repeater

An arrangement for determining radio coverage provided by a telecommunications system to a user of a mobile device is disclosed. In the case of a GSM or UMTS mobile device, if the device is in the idle mode (step A) and if a paging operation is not scheduled (step B), the mobile device records and stores on the mobile device a characteristic of the radio coverage provided when the mobile device is at each of a plurality of locations visited by the user of the mobile device (step C). The arrangement also enables retrieval of the recorded and stored characteristic so that radio coverage provided to the device for the user at the locations can be evaluated. If the telecommunications system includes a plurality of networks, the mobile device will record and store the characteristic for each of the plurality of networks. The arrangement then enables the radio coverage provided by the respective networks to be evaluated, and an informed choice as to the best network for that particular user can be made.

Radio coverage mapping for telecommunications network

A system for distributing a radio frequency (RF) signal using a data cable system includes a method and apparatus with components that receive the RF signal, determine the passband of the data cable system, spread the RF signal within the passband as a spread signal, insert the spread signal into the cable system, extract the spread signal from the data cable system as an extracted signal, convert the extracted signal to a transmission frequency as a converted signal, and transmit the converted signal.

Radio frequency distribution with spreading

A system for distributing radio frequency signals using a data cable system includes a method and components that receive a radio frequency (RF) signal, identify at least one unoccupied channel on the data cable system, convert the RF signal to the frequency associated with an unoccupied channel as a converted signal, insert the converted signal into the cable, extract the converted signal from the cable as an extracted signal, convert the extracted signal to a transmission frequency as a transmission signal, and transmit the transmission signal at the transmission frequency.
