Techniques for minimizing latency and latency jitter in communication transmission systems are provided. In some embodiments, a first communication transmission system in a chain is configured to operate in accordance with a particular signal processing mode. Operating in accordance with the particular signal processing mode causes user data received in a first wireless signal to bypass a first set of one or more processing modules in an upstream receiver and a second set of one or more processing modules in a downstream transmitter. After the user data has bypassed the first and second set of processing modules, a second wireless signal that includes the user data is transmitted to a third communication transmission system in the chain. In other embodiments, the signal processing mode may be adaptively changed based on one or more conditions that are monitored along the chain.

Data communication over a frame synchronized digital transmission network

A multi-radio device system includes a set of sending radio devices and a set of receiving radio devices. Among the sending radio devices is a load-balancing radio device that receives data packets from an originating network. The load-balancing radio device labels data packets with sequence numbers and distributes the labeled data packets among the sending radio devices based on the relative capacities and statuses of those sending radio devices. The sending radio devices transmit the labeled data packets to the receiving radio devices. The receiving radio devices send the labeled data packets to an aggregating radio device within the set of receiving radio devices. The aggregating radio device uses the sequence numbers to ensure that the data packets are forwarded to a destination network in the correct order, extracting original data packets from the labeled data packets before forwarding the original data packets on toward the destination network.

Radios synchronize their timing mechanisms using a timing signal that those radios propagate from one radio to another. Radios that are close to each other transmit only during times that none of the other nearby radios is trying to receive. In one scheme, a 'master' radio initiates communication while another 'slave' radio responds in a pre-determined manner. The master generates and propagates an inverted timing signal to the slave, which propagates approximately the same inverted timing signal to other radios in the slave's cluster. Each radio can be in one of three different modes: &#x201c;source,&#x201d; &#x201c;auto,&#x201d; and &#x201c;recipient&#x201d; modes. A &#x201c;source&#x201d; radio generates a timing signal independently. A &#x201c;recipient&#x201d; radio uses a received timing signal and forwards it to other radios. An &#x201c;auto&#x201d; radio behaves as a &#x201c;recipient&#x201d; radio while a timing signal is detectable, but behaves as a &#x201c;source&#x201d; radio if the timing signal is lost.
