A method and a system are provided for reducing collisions created between endpoints in a wireless local area network environment incorporated with a distributed antenna system (DAS), wherein the DAS comprises a plurality of station units (STUs) each adapted to communicate wirelessly with one or more wireless stations, and at least one access point unit (APU) connected to the plurality of STUs and adapted to communicate with a respective access point. The method comprises: at a first STU belonging to the plurality of STUs, receiving a first signal transmitted wirelessly; conveying the first signal towards the APU; and at the APU, adapting the conveyed signal to be transmitted to the access point associated with the APU, and in response to receiving the first signal, conveying a return signal towards at least two STUs belonging to the plurality of STUs.

Provided herein is a dynamically coordination of a distribution of radio signals via distributed remote radio units, with respect to changing numbers and locations of user equipment. A distributing and combining unit combines uplink radio signals from the remote radio units and distributes downlink radio signals from the access unit according to dynamically changing specified criteria. A measurement unit measures performance indicators of the communication between the remote radio units and the mobile communication devices into a matrix of performance indicator values, calculates cost functions therefrom and generates output execution parameters by applying a decision process based on the calculated cost function. Communication criteria are dynamically updated according to the generated output execution parameters and the process is continuously iterative. The invention allows incorporating smart capabilities into legacy networks without any major physical changes of the network.

A way of optimizing communication by minimizing the momentary overall radiated energy under constraints in respect to coverage and maintenance of communication with the users, is provided herein. Channel parameters are estimated from downlink and/or uplink communications or from user equipment messages and desirable gain factors are derived from the minimization. The optimization is reiterated continuously to dynamically adapt the communication system to varying conditions.

A method for carrying out a handover procedure, following which a mobile terminal (MS) currently in communication with a first base station (BS), will communicate via a second BS. The method includes upon initiating a handover procedure, determining that the MS will receive all future IP packets via the second base station, following this determination and prior to establishing a connection between the MS and the second BS, forwarding all IP packets being addressed to the MS to the second BS, and buffering the received IP packets thereat, and upon establishing a connection between the MS and the second BS, forwarding the IP packets that were buffered at the second BS to the MS, wherein the buffered IP packets are delivered to the MS before delivering any packets addressed thereto along a new path extending to the second BS which does not include the first BS.

A method device and system are provided for managing a wireless local area network comprising a plurality of station units (STAs), where each of the plurality of station units is adapted to wirelessly communicate with one or more access points. The method device and system comprises affecting power control over air time request packets transmitted by respective station units from among the plurality of STAs towards one of the one or more access points, so that all air time request packets are received at said access point at substantially the same Signal to Noise Ratio (SNR), and wherein said power control does not affect packets carrying payload data that proceeds the air time request packets transmitted by the respective station units.
