Third generation (3g) mobile service over catv network
First Claim
1. A method for providing bidirectional wireless RF cellular communication through a CATV network, comprising:
- providing a bypass device at an active point in a CATV network; and
communicating frequency shifted wireless RF cellular signals and CATV signals, over the CATV network, between an access point of the CATV network and an indoor termination point of the CATV network;
wherein the CATV signals are communicated via the active point and the shifted wireless RF cellular signals are communicated via the bypass device.

Abstract
A CATV network (141) designed to distribute television and other services in using radio frequencies below a certain frequency (typically 860 HMz) is modified to add a secondary transmission bi-directional capability above this frequency. The secondary bi-directional network (101, 102) is established by adding filters to separate modified mobile-communications frequencies (above 860 MHz) from conventional CATV services (below 860 MHz). Third generation (3G) networks and second generation (2G) networks are together merged with CATV networks. Cable TV networks are used to provide in-building access for 3G and 2G mobile radio terminals, in a mobile radio network. A Cable Mounted Third Generation Module acts as a transmit receive antenna and frequency translator for the 3G signals.

19. A system for simultaneously communicating Third Generation (3G) cellular traffic and Second Generation (2G) traffic over a cable television (CATV) network, comprising:
-
a Cellular Entrance Module (CEEM) at an access point of the CATV network, receiving original downlink signals, including original 3G downlink signals and original 2G downlink signals, and shifting the original downlink signals to a frequency band higher than television signals of the CATV network to provide shifted cellular signals, including shifted 3G downlink signals and shifted 2G downlink signals;
a Cable Mount Third Generation Module (CMTGM) at an indoor termination point of the CATV network, receiving original uplink signals, including original 3G uplink signals and original 2G uplink signals, and shifting the original uplink signals to a frequency band higher than television signals of the CATV network to provide shifted cellular signals, including shifted 3G uplink signals and shifted 2G uplink signals; and
a Cellular Transport Module (CETM) at an active component of the CATV network, the shifted cellular signals being communicated over the CATV network between the CEEM and CMTGM via the CETM. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)
