Abstract: Communications within a computer network may be controlled by determining that conditions within a first communication channel communicatively coupling components of the computer network are becoming unacceptable for continued utilization of the communication channel and then switching communications within the computer network to a second communication channel. Interference conditions therein preferably being less severe than interference conditions within the first communication channel. The switching may initiated by one of the network components and generally includes placing communications within the first communication channel in a standby condition while searching for an available communication channel. This may be accomplished by instructing the components of the computer network to remain quiet while one of the components searches for an available communication channel, for example by tuning an associated radio to listen in the second communication channel. Ultimately, network communications may be established in the second communication channel. This may include setting up bandwidth connection agreements with each of the components of the computer network for the second communication channel and/or polling for each of the components of the computer network in the second communication channel.

Abstract: A communication channel is controlled so as to dynamically accommodate network client requests for access thereto. The communication channel may be supported on a wireless link, such as a spread spectrum wireless link, and client requests for access thereto may be dynamically accommodated by allocating time slots for client transmissions on the wireless link. Providing a quiet time slot within which clients may request access to the communication channel may accommodate various client requests for access to the communication channel. These quiet slots may exist with other forward and reverse time slots which are superimposed on the communication channel, each forward and reverse time slot including one or more data frames. The forward and reverse time slots are preferably fixed, but negotiable, time periods. Each of the data frames may include a plurality of data packets, each of the data packets being variable in length. Preferably, each of the data packets includes error correction coding information as well as information which may be used to synchronize pseudo-random number generators of a transmitter and a receiver operating according to the communication protocol. Each of the data frames may further include link identification information that uniquely identifies a wireless link supporting the communication protocol.

Abstract: Within a computer network, a first one of a number of clients may be a consumer of information included within one or more data streams transmitted between a server and one or more others of the clients. However, each of the clients are also communicatively coupled to the server via a command channel independent of these data streams. In some cases, the first client receives the information as the data streams are transmitted from the server to the other clients, while in other cases the first client receives the information as it is being transmitted from the other clients to the server. In addition to the data streams, the first client may exchange additional information with the server. The data streams may be transmitted on a wireless communication link communicatively coupling the server and the clients. However, the first client may receive the information via a communication path separate from the wireless communication link. In some cases the information represents only a portion of the data streams transmitted between the server and the clients. Bandwidth within the network may be allocated by partitioning a communication channel into a number of slots according to bandwidth needs of information consumers and information providers within the network; and sharing at least one of the slots among two of the information consumers within the network.
