Abstract
Multi-radio antenna apparatuses and stations for wireless networks including multiple radios coupled to a single transmit/receive antenna, in which the antenna is highly synchronized by an external (e.g., GPS) signal. These multi-radio antenna systems may provide highly resilient links. Synchronization may allow these apparatuses to organically scale the transmission throughput while preventing data loss. The single transmit/receive antenna may have a single dish or a compound (e.g., a single pair of separate transmitting and receiving dishes) and connections for two or more radios.
Claims20
A method for operating a radio system, the method comprising:
- transmitting, by a plurality of radios, a preamble, wherein the preamble is transmitted simultaneously by the plurality of radios;
- generating an output signal by at least a subset of the plurality of radios, wherein a respective frequency channel of a given output signal for one radio is different from a respective frequency of a given output signal for each other radio;
- combining respective output signals from the plurality of radios to form a transmission signal;
- and
- transmitting the transmission signal from a single antenna.
An apparatus for transmitting radio signals comprising:
- a plurality of radios configured to:
- transmit, by a plurality of radios, a preamble, wherein the preamble is transmitted simultaneously by the plurality of radios;
- generate, from at least a subset of the plurality of radios, an output signal, wherein a respective frequency channel of a given output signal for one radio is different from a respective frequency of a given output signal for each other radio;
- combine, by a combiner, a respective output signal from the plurality of radios to form a transmission signal;
- and
- a single antenna configured to transmit the transmission signal.
A method for operating a radio system, the method comprising:
- Synchronizing a plurality of radios to operate with identical transmit and receive duty cycles based on an external clock signal received at each of the plurality of radios, wherein the external clock signal is a based at least in part on a global positioning satellite (GPS) signal;
- generating an output signal by at least a subset of the plurality of radios, wherein a respective frequency channel of a given output signal for one radio is different from a respective frequency of a given output signal for each other radio;
- and
- simultaneously transmitting respective output signals from the plurality of radios through a single antenna.
