REMOTE DISTRIBUTED ANTENNA SYSTEM
First Claim
1. A system, comprising:
- a memory to store instructions; and
a processor, coupled to the memory, to facilitate execution of the instructions to perform operations, comprising;
facilitating receipt of a first signal from a base station device;
selecting, according to a network traffic condition, a subcarrier from a set of subcarriers to identify a selected subcarrier for directing the first signal to a remote antenna of a remote antenna system;
converting, according to the selected subcarrier, a carrier wave signal with the first signal to generate a frequency converted signal at the selected subcarrier;
generating a first transmission that includes the frequency converted signal at the selected subcarrier, the first transmission further comprising metadata that indicates that the selected subcarrier in the first transmission is assigned to another system coupled to the remote antenna of the remote antenna system; and
directing the first transmission to at least a portion of the remote antenna system wirelessly.

Abstract
A distributed antenna system is provided that frequency shifts the output of one or more microcells to a 60 GHz or higher frequency range for transmission to a set of distributed antennas. The cellular band outputs of these microcell base station devices are used to modulate a 60 GHz (or higher) carrier wave, yielding a group of subcarriers on the 60 GHz carrier wave. This group will then be transmitted in the air via analog microwave RF unit, after which it can be repeated or radiated to the surrounding area. The repeaters amplify the signal and resend it on the air again toward the next repeater. In places where a microcell is required, the 60 GHz signal is shifted in frequency back to its original frequency (e.g., the 1.9 GHz cellular band) and radiated locally to nearby mobile devices.

10. A first system, comprising:
-
a memory to store instructions; and a processor, coupled to the memory, to facilitate execution of the instructions to perform operations, comprising; receiving a first wireless transmission, the first wireless transmission including a first modulated signal having a first subcarrier of the first wireless transmission, the first subcarrier assigned to the first system, wherein a second system generates the first wireless transmission by converting a first carrier wave signal with a first signal in a frequency band to generate the first modulated signal having an operating frequency different from the frequency band, wherein the second system selects the first carrier wave signal according to a network traffic condition, and wherein the first carrier wave signal selected by the second system places the first modulated signal at the first subcarrier of the first wireless transmission; generating the first signal from the first wireless transmission, wherein the first signal is in the frequency band; transmitting the first signal to a communication device; and retransmitting at least a portion of the first wireless transmission to generate a second wireless transmission. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17)

18. A method, comprising:
-
receiving, by a device comprising a processor, a wireless transmission directed to a first remote antenna, the wireless transmission generated by mixing a first carrier wave signal with a first signal of a plurality of signals in a frequency band to generate a first modulated signal having a first operating frequency different from the frequency band, wherein the first modulated signal is located in a first channel of a plurality of channels included in the wireless transmission, and wherein the first carrier wave signal is selected, according to a network traffic condition at the first remote antenna, for placement of the first modulated signal at the first channel of the plurality of channels included in the wireless transmission; determining, by the device, that the first signal at the first channel of the plurality of channels included in the wireless transmission is assigned to the first remote antenna for processing; generating, by the device, the first signal in the frequency band; transmitting, by the device, the first signal directed to a communication device; and retransmitting, by the device, at least a portion of the wireless transmission directed to a second remote antenna. - View Dependent Claims (19, 20)
