Wireless terrestrial communications systems using a line-of-sight frequency for inbound data and a non-line-of-sight frequency for outbound data

A user unit that provides Internet access, comprising:

• a wireless receiver that is configured to receive inbound data from an Internet service provider from a first terrestrial link;
• and
• a wireless transmitter that is configured to wirelessly transmit outbound data to the Internet service provider from a second terrestrial wireless link;
• wherein the frequency band of the first terrestrial link is in a first frequency band between 11.0 GHz-13.0 GHz and wherein the frequency band of the second terrestrial link is in a second frequency band between 0.7 GHz-3.0 GHz.

A terrestrial communications system comprising:

• one or more terrestrial base stations for transmitting a first set of signals to a plurality of user units and receiving a second set of signals from the plurality of user units;
• and,
• each of the user units including a transceiver for transmitting the second set of signals to the base station and for concurrently receiving the first set of signals from the base station;
• wherein the first set of signals are in a first frequency band between 11.0 GHz-13.0 GHz and wherein said second set of signals are in a second frequency band between 0.7 GHz-3.0 GHz.
