Abstract
A method includes, in a physical layer of a communication stack of a wireless communication device, receiving a first radio frequency (RF) signal, converting the first RF signal to a first digital data signal, and passing the first digital data signal to a higher communication stack layer. The method also includes, in the physical layer, receiving a second digital data signal from the higher communication stack layer, converting the second digital data signal to a second RF signal, and transmitting the second RF signal. The method further includes, in the physical layer, forwarding a signal, wherein forwarding comprises receiving a third RF signal, converting the third RF signal to a fourth RF signal, and transmitting the fourth RF signal.
Claims21
A method comprising:
- in a physical layer of a communication stack of a wireless communication device, receiving a first radio frequency (RF) signal in a first time slot, converting the first RF signal to a first digital data signal, and passing the first digital data signal to a higher communication stack layer;
- in the physical layer, receiving a second digital data signal from the higher communication stack layer, converting the second digital data signal to a second RF signal, and transmitting the second RF signal;
- and
- in the physical layer, forwarding a signal by receiving a third RF signal in a second time slot, converting the third RF signal to a fourth RF signal, and transmitting the fourth RF signal, wherein a time period that elapses between the receiving of the third RF signal and the transmitting of the fourth RF signal is substantially equal to a delay in forwarding a packet from a receiver to a transmitter within the physical layer.
An apparatus, comprising:
- a wireless communication device configured to be coupled to an antenna, the wireless communication device comprising a communication stack, wherein the wireless communication device is adapted to:
- in a physical layer of the communication stack, receive a first radio frequency (RF) signal in a first time slot, convert the first RF signal to a first digital data signal, and pass the first digital data signal to a higher communication stack layer;
- in the physical layer, receive a second digital data signal from the higher communication stack layer, convert the second digital data signal to a second RF signal, and transmit the second RF signal;
- and
- in the physical layer, forward a signal by receiving a third RF signal in a second time slot, converting the third RF signal to a fourth RF signal, and transmitting the fourth RF signal, wherein a time period that elapses between the receiving of the third RF signal and the transmitting of the fourth RF signal is substantially equal to a delay in forwarding a packet from a receiver to a transmitter within the physical layer.
An apparatus comprising:
- a first antenna, wherein the first antenna is a directional antenna;
- a second antenna, wherein the second antenna is a directional antenna;
- and
- a wireless communication device coupled to the first antenna and the second antenna, the wireless communication device comprising a communication stack, wherein the wireless communication device is adapted to:
- in a physical layer of the communication stack, receive a first radio frequency (RF) signal in a first time slot, convert the first RF signal to a first digital data signal, and pass the first digital data signal to a higher communication stack layer;
- in the physical layer, receive a second digital data signal from the higher communication stack layer, convert the second digital data signal to a second RF signal, and transmit the second RF signal;
- and
- in the physical layer, forward a signal by receiving a third RF signal via the first antenna in a second time slot and transmitting a corresponding fourth RF signal via the second antenna, wherein a time period that elapses between the receiving of the third RF signal and the transmitting of the fourth RF signal is substantially equal to a delay in forwarding a packet from a receiver to a transmitter within the physical layer.
