Problems solved by technology

Although standard 2x2 MIMO solutions utilize both vertical and horizontal links, performance at long distances is limited by the use of only a single radio on each side of the wireless link in a half-duplex configuration

Embodiment Construction

[0028] Three-sector design

[0029] Currently, standard MIMO outdoor base stations utilize 2x2 (2 transmit chains, 2 receive chains) MIMO radio chips along with bipolar (vertical and horizontal) antennas. This setting only uses 1 vertical chain and 1 horizontal chain and combines part of the received signal between the two chains.

[0030] In an embodiment of the present invention, the base station can optionally utilize a 2x3 (2 transmit chains, 3 receive chains) MIMO radio chip, which provides additional received signal gain compared to a conventional 2x2 MIMO system, such as figure 2 This is discussed in further detail. For example, the system may still only transmit in two streams, but the radio in the base station may utilize a third receiving chain, for example, one radio uses the vertical polarization of the additional antenna and the other radio uses the horizontal pole of the additional antenna. 化. This will not create additional interference between the two radios in t...

Abstract

System enhancement(s) are disclosed that can add capabilities, such as, using Frequency Division Multiple Access (FDMA) and/or Time Division Multiple Access (TDMA) and/or Frequency Division Duplex (FDD) capabilities along with Multi-Input Multi-Output (MIMO) antennas and/or Global Positioning System (GPS) synchronization. The use of two radios in both the base-station and the subscriber-station, i.e., customer premises equipment (CPE), e.g., can allow frequency division to be utilized, exploiting higher receive gains at the CPE while not affecting transmissions occurring on the other radio's frequency.
