Abstract: A tentative location of a transmitter in an indoor environment is determined by triangulation, using at least two direction finders. The tentative location is made more accurate by performing at least one added action selected from the following: checking the likelihood that the tentative location is an accurate location by comparing measured transmitter signal strengths with calculated signal strengths, using a known indoor environment structure, using a record of the transmitter movement through the indoor environment for determining whether the transmitter is located in an obscured area of the indoor environment or performing an alignment procedure on the antennas to improve the triangulation.

Abstract: Traffic passing between remote terminals and corporate intranets through an access server provider network can encounter security and addressing problems. Intercepting and manipulating this traffic can overcome these, as well as other problems. For such traffic that is being transported over a plurality of Network Based Tunnels (NBT), this manipulation can be performed by manipulation equipment that may reside in the access server provider's network between an Access Gateway (AGW) and a Border Gateway (BGW). The manipulation equipment may manipulate received NBT packets by parsing the original packet that is encapsulated in the NBT packet, manipulating the original packet and reconstructing the NBT packet with the manipulated data of the original packet.

Abstract: A system and method or accurate location identification of a mobile cellular telephone in an indoor environment in case of emergency are provided. The system comprises elements of a distributed antenna system (DAS) and at least one location identification unit (LIU) coupled to the DAS and operative to extract the location of the mobile cellular telephone from RF signals obtained from the DAS. The LIU includes a receiver operative to receive the signals, preferably from a base unit (BU) of the DAS, and a processor operative to process the signals. The LIU obtains parameters of the emergency call that define a tuning window from an external system, and, using the tuning window, identifies a remote hub unit (RHU) of the DAS with the highest signal energy at the tuning window as the RHU through which the call was acquired. The location of the mobile cellular telephone is then determined as being in the area covered by this RHU.

Abstract: In a wireless communication system, each of a plurality of passive antennas is operationally connected to one or more WLAN access points via a respective active component, for example a bidirectional amplifier, of a WLAN service combiner. Optionally, for each antenna, a cross-band duplexer in the WLAN service combiner provides an operational connection to cellular services. Alternatively, the antennas are dedicated to the WLAN access point(s). Such a system provides WLAN services in areas of a building using only enough WLAN access points per area to provide adequate capacity.

Abstract: A method for proposing at least one transmission rate change including calculating a plurality of latency values, computing at least one derivative-based proposed change from the plurality of latency values, and proposing a rate change selected from the at least one derivative-based proposed change. Also provided is a system including a rate controller controlling the transmission rate of data between two stations over a network and a rate reporter in communication with the rate controller.

Abstract: As part of the system and method of the present invention, either a Client Agent and/or a Predictive Server intercept a request from a client to a server, and a response from the server to the client. Based on information derived from the client/server communication, either the Client Agent or the Predictive Server generates a predictive request for data. The server's response to the predictive request is stored at either the Client Agent or the Predictive Server, and is forward to the client when the client generates a request for the data contained in the response.
