Methods and systems for hybrid point to multipoint communication systems having multiple downlink channels and a single uplink channel, including the steps of centrally allocating bandwidth to, and synchronizing communications with, a first and a second wireless clients; transmitting, over a shared signal wired distribution line, a first downlink signal transported over a first frequency, a second downlink signal transported over a second frequency, and an uplink signal transported over a fifth frequency; converting the frequency of the first downlink signal to a third frequency, and bi-directionally wirelessly communicating with a first wireless client over the third frequency; converting the frequency of the second downlink signal to a fourth frequency, and bi-directionally wirelessly communicating with a second wireless client over the fourth frequency; and converting and superpositioning a first received wireless uplink signal having the third frequency and a second received wireless uplink signal having the fourth frequency to the uplink signal that is transmitted over the shared signal wired distribution line using the fifth frequency.

Methods and systems for hybrid point to multipoint communication systems, including the steps of: determining transmission synchronization and bandwidth allocation between a first wireless client and a second wireless client communicating via a common communication channel; transmitting a download multi carrier transmission, via a shared signal wired distribution line, wherein the download multi carrier transmission comprises the determined transmission synchronization and bandwidth allocation; receiving the download multi carrier transmission by a first hybrid converter and by a second hybrid converter connected to the shared signal wired distribution line; shifting the frequency of the download multi carrier transmission from a wired distribution line frequency to a wireless frequency in the first hybrid converter and in the second hybrid converter; and transmitting the frequency-shifted download multi carrier transmission to the air from the first hybrid converter and from the second hybrid converter.

Methods and systems for filtering and enhancing the uplink reception sensitivity of OFDMA hybrid point to multipoint communication systems, including the steps of: determining transmission synchronization and bandwidth allocation for a plurality of wireless clients; communicating with the wireless clients via a plurality of hybrid converters connected to a shared signal distribution line, by using a wireless point to multi point centralized synchronizing communication controller and an OFDMA modulation; receiving wireless upload transmission by using the hybrid converters; and blocking non-information carrying sub-carriers, received by at least one of the hybrid converters, before superpositioning the received wireless upload transmissions on the shared signal distribution line.

Filtering process for enhancing OFDMA uplink reception sensitivity

Methods and systems for simultaneous transmission of simulcast and single cast information over a hybrid point to multipoint communication systems, including the steps of: selecting an area to be ubiquitously covered by a common channel; assigning a first wireless client to the common channel; assigning a second wireless client to a first private channel; setting a first hybrid converter and a second hybrid converter having an aggregated coverage area that comprises the selected area; connecting the first hybrid converter using an orthogonal multi-carrier transmission having a first frequency and the second hybrid converter using an orthogonal multi-carrier transmission having a second frequency to a centralized synchronizing communication controller via a shared signal wired distribution line; converting, by using the first hybrid converter, the first frequency transmission to a third orthogonal multi-carrier wireless transmission having a third frequency; converting, by using the second hybrid converter, the second frequency transmission to a fourth orthogonal multi-carrier wireless transmission having the third frequency; and creating a downlink ubiquitous coverage in the selected area by transmitting the third and the fourth transmissions, each comprising a common MAP over a first sub-channel, a common payload over a second sub-channel, and a first private payload and a second private payload, correspondingly, over a third sub-channel, wherein the third and fourth transmissions are at least partially coverage-overlapping and are synchronizing and bandwidth allocating a first wireless client and a second wireless client.
