Abstract: A cellular communications network 10 comprises a plurality of basestations 12, 14, 16 and 18 connected to each other through an interface and to a core network through another interface. Each basestation has a coverage area referred to as a cell k. There are provided methods for estimating the load imparted on a cell in the cellular communications network by user equipments in the cell. The methods make it possible to estimate any potential increase in the load that may impact onto a target cell due to the handover of a UE from a serving cell.

Abstract: A wireless access device is operable in a mode in which its maximum transmit power is set to a value that means that the device has a range of less than 1 metre. This allows the device to operate as a basestation in a cellular communications network, even in locations in which it is not specifically licensed, because the power level is so low that it will not cause interference on the licensed frequencies. The wireless access device is designed such that a handheld portable device can be maintained in a close spatial relationship to it.

Abstract: An intelligent gain controller (IGC) for an on-frequency repeater implements a method for identifying a desired narrow band signal within a broadband RF signal. Thus, a candidate narrow band signal within the broadband signal is isolated. The isolated narrow band signal is then processed to detect repeating features of the narrow band signal. The detected repeating features are then analyzed to identify the signal type of the isolated narrow band signal. System gain of the in-frequency repeater can be controlled based on the power level of the identified narrow band signal.

Abstract: A repeater system of a wireless network includes at least one adaptive repeater module and a personality module. The adaptive repeater module includes a hardware signal path for processing an input RF signal to generate a corresponding output RF signal; and a controller unit including a micro-processor for controlling parameters of the hardware signal path in accordance with a software program. The personality module is removably connectable to the adaptive repeater module, and includes a computer readable medium for storing the software program.

Abstract: Methods are provided for compensating the electrical path delay imposed on signals traversing a repeater. In some embodiments, the repeater generates an output signal having an undelayed signal component. Detection of the undelayed signal component enables establishment of a low error timing reference. In other embodiments, the repeater superimposes a low level signature onto signals traversing the repeater. The signature includes embedded information, from which a receiver can determine an accurate time reference.

Abstract: In a system for monitoring stability of an on-frequency repeater, a wide-band signature (WBS) signal associated with the repeater is generated, and inserted into an output RF signal transmitted by the repeater. Signal components corresponding to the WBS signal in an input RF signal received by the repeater are detected and analyzed to estimate a feedback path loss L.

Abstract: A distributed adaptive repeater system includes a donor unit, two or more coverage units (CUs), and an intelligent hub. The donor unit operates to maintain bidirectional wireless communication with a base station of a wireless communications network. Each coverage unit maintains bidirectional wireless communication with transceivers located within a respective coverage area, and is further adapted to independently control a signal path gain to ensure stability of a respective feedback loop to the donor unit. Finally, the intelligent hub is operatively coupled between the donor unit and the coverage units, and adapted to monitor a status of each coverage unit.

Abstract: An intelligent gain controller (IGC) for an on-frequency repeater includes a broadband gain controller (GC) for amplifying a broadband radio frequency (RF) signal within a broadband signal path of the repeater. A narrowband receiver isolates a narrowband signal within the broadband RF signal. A processor determines a power level of the narrowband signal, and controls the gain of the broadband GC in accordance with the determined power level.
