    Abstract: A method for communication over a communication link, which includes a transmitter and a receiver, includes transmitting and receiving data, which is encoded using a specified forward error correction (FEC) code, modulated using a specified modulation scheme and transmitted at a given power level.One or more parameters of the communication link are monitored. A condition, which is based on values of one or more of the parameters monitored at a plurality of historical time instants, is evaluated. At least one feature of the transmitted data, selected from a group of features consisting of the FEC code, the modulation scheme and the power level, is modified based on the condition.

    Abstract: A network controller for facilitating roaming of a mobile wireless communications device between access points communicates with at least one access point over a wired network which, in turn, communicate with a mobile wireless communications device over a wireless network. The network controller includes a data processing system including a protocol stack that facilitates a communication session between the mobile device and a network device on the wired network, and a session table identifying session information for each said communication session. The session information identifies the current access point with which the mobile device is currently associated. The protocol stack updates the session table from session information received from the current access point, maintains a first virtual circuit with the network device, maintains a second virtual circuit with the current access point, and bridges communication between the virtual circuits in accordance with the session information.

    Abstract: In a wireless system comprising at least one transceiver configurable for communication over a wireless communication channel, the transceiver comprising a transmitter and a receiver, a method for controlling a data transmission rate of the at least one transceiver comprises the steps of: (i) determining a signal quality characteristic corresponding to a signal received at the receiver by measuring a difference between one or more reference constellation points and one or more received constellation points, the signal quality characteristic representing an estimation of signal degradation; and (ii) modifying a data transmission rate of the transmitter based, at least in part, on the signal quality characteristic.

    Abstract: A telecommunication arrangement with modems (MCO; MCPE) having a receiving module (URx; DRx) able to receive channels of signals via a communication line (LN). The arrangement preferably operates according to the xDSL protocol. The receiving module of each modem is associated to storage means (USN, DSN; LDN) storing a “channel condition model” corresponding to operational conditions of the channel, preferably to the “worst case”. The channel condition model is determined by previously measured operational conditions of this channel and/or by a channel condition model managed externally to the modem, and which is stored in the storage means before the initialization of the modem. In different variants, the channel condition model is a model of the noise level, the signal-to-noise ratio, the actual or the maximum bitloading (bi) per carrier of the channel and/or mathematical operations on these. The channel condition model is further updated at regular time intervals during initialization or showtime. The modem may be located at the Central Office (CO) or at the Customer Premises Equipment (CPE). The receiving module (URx) of the CO modem (MCO) may receive the channel condition model from the central office management device via a management interface. The channel condition model may also be transmitted from the central office management device to the receiving module (DRx) of the CPE modem (MCPE), and channel condition measurement information may even be fed back.

    Abstract: A method for calibrating rates at which data is transmitted in a communication system. There is a short transmission utilizing a first set of communication parameters comprising first and second communication parameters. The first set of communication parameters are different from the second set of communication parameters used to create stable communication between the transmitter and receiver. The second set of communication parameters comprise first and second communication parameters. Then determining that there are substantially no errors associated with reception of the short transmission by the receiver. Then transmitting a long transmission utilizing a third set of communication parameters comprising first and second communication parameters. The first communication parameter of the third set is equal to the first communication parameter of the first set. The second communication parameter of the third set is equal to the second communication parameter of the second set.
