Abstract: The preferred embodiment comprises a rack with frames that facilitates easy installation of rack mount servers. Each frame consolidates the individual power receptacles into a single line cord by offering individual power control over each installed server. Each frame further consolidates the individual K/V/M connections into a concentrator switch embedded in the frame itself. This presents the user with a single K/V/M connection that is switchable between the installed servers via a user interface. Also included is a USB hub connecting all servers to a common USB interface. Alternatively, network, serial, and parallel ports can also be included.

The method comprises the steps of receiving a signal transmission 124A from a remote station 112, determining if the signal transmission 124A includes a discriminant applied to the signal transmitted from the remote station 112 and designating the signal transmission 124A as being transmitted via the repeater 120 if the signal transmission 124A includes the discriminant.

Abstract: The system monitors traffic on a CDMA repeater. The system receives a metric related to the operation of the CDMA repeater and automatically determines the amount of call traffic on the CDMA repeater based on the metric. The metric related to operation of the CDMA repeater could be the signal power from the CDMA repeater. The amount of the call traffic on the CDMA repeater could be measured by determining the number of users on the CDMA repeater. The number of users could be determined from a formula where the signal output is proportional to the number of users on the CDMA repeater. The system may also store or transmit to a remote location the metric or the amount of call traffic on the CDMA repeater.

Abstract: The invention includes methods and systems for use in a wireless communications system, such as a CDMA mobile communications system. A communications device transmits a wireless signal. A repeater system receives a first version of the wireless signal using a first receiver system and receives a second version of the wireless signal using a second receiver system. The repeater system switches between the first version of the wireless signal and the second version of the wireless signal to generate a third version of the wireless signal. The repeater system transmits the third version of the wireless signal and a base station system receives the third version of the wireless signal. In some embodiments of the invention, the wireless signals are Code Division Multiple Access (CDMA) signals. In some embodiments of the invention, the switching occurs at a rate of 4 MHz.

Abstract: The invention includes methods and systems to improve the signal diversity between a repeater and a base station in a wireless communication system. A communications device transmits a wireless signal. The repeater receives two versions of the wireless signal using a first receiver system and a second receiver system. The repeater transmits two versions of the wireless signal that correspond to the two received versions. The repeater transmits the two versions with different signal polarizations so they can be isolated from one another at the base station. The base station receives the two versions from the repeater and isolates each version based on the difference in polarization. The base station processes the two diverse versions to produce a high-quality signal. The use of different polarizations to provide diverse signals between the repeater and the base station lowers signal power requirements and increases the capacity of CDMA systems.

Abstract: The present invention is a novel and improved method and apparatus for transmitting and receiving code division multiple access (CDMA) signals. In a described embodiment of the invention, the radio frequency (RF) signals are received through a first polarization RF unit and a second polarization RF unit generating right slant samples and left slant samples. The right slant samples and the left slant samples are each searched and multipath processed independently and the resulting sets of soft decision data combined and decoded. In a preferred embodiment of the invention, right slant and left slant instances of the signal are generated and transmitted to increase the likelihood of differently polarized instances of the signal being available at the receive system.

Abstract: In a communications network, a network user communicates using a remote unit with another user via at least one base station. The network is comprised of first and second mobile switching control stations respectively controlling communications through a first set of base stations including a first base station and through a second set of base stations including a second base station. To direct communications between the remote unit and the first and second base stations the first base station measures a round trip delay of an active communication signal between the first base station and the remote unit. The remote unit measures a first phase offset of a pilot signal received from a first candidate base station and reports it to the first mobile switching center via the first base station.
