Abstract

A system and method for improved data transmission on a wireless link to a remote receiving node includes a communication device for converting packets to RF at a physical data rate, an antenna apparatus having a plurality of antenna configurations for transmitting the RF, and a processor for selecting the antenna configuration and the physical data rate based on whether the remote receiving node indicated reception of the data transmission. A plurality of antenna configurations may be mapped, as well as a plurality of physical data rates. A logical antenna and a logical data rate may be selected for transmission of a packet. The logical antenna may be changed based on whether the packet is received by a remote receiving node.

Claims (34)

1. A method for transmission parameter control, the method comprising:

mapping each of a plurality of selectable element antenna configurations of an antenna apparatus to a logical antenna;

mapping each of a plurality of physical data rates to a logical data rate;

selecting a first logical antenna;

selecting a first logical data rate, wherein the first logical data rate provides a first effective user data rate at a remote receiving node;

transmitting a packet to the remote receiving node with the first logical antenna at the first logical data rate;

determining whether the remote receiving node received the packet;

changing the first logical antenna based on the determination;

selecting a second logical data rate;

transmitting a probe packet to the remote receiving node at the second logical data rate;

determining a second effective user data rate based on a determination whether the remote receiving node received the probe packet; and

changing the first logical data rate to the second logical data rate based on the second effective user data rate.

2. The method of claim 1 , further comprising:

computing a first link quality metric for the first logical antenna;

selecting a second logical antenna;

transmitting a probe packet to the remote receiving node with the second logical antenna;

determining a second link quality metric based on a determination whether the remote receiving node received the probe packet; and

changing the first logical antenna to the second logical antenna based on the second link quality metric.

3. The method of claim 2 wherein each link quality metric includes a success ratio computed by comparing a number of packets transmitted to the remote receiving node with the logical antenna and a number of the packets indicated as received by the remote receiving node.

4. The method of claim 2 wherein each link quality metric includes a received signal strength indicator.

5. The method of claim 1 wherein selecting a first logical antenna is based on a ranking of available antenna configurations.

6. The method of claim 1 wherein changing the first logical antenna is based on a threshold value in a ranking of available antenna configurations.

7. A non-transitory computer-readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for transmission parameter control, the method comprising:

mapping each of a plurality of selectable element antenna configurations of an antenna apparatus to a logical antenna;

mapping each of a plurality of physical data rates to a logical data rate;

selecting a first logical antenna;

selecting a first logical data rate, wherein the first logical data rate provides a first effective user data rate at a remote receiving node;

transmitting a packet to the remote receiving node with the first logical antenna at the first logical data rate;

determining whether the remote receiving node received the packet;

changing the first logical antenna based on the determination;

selecting a second logical data rate;

transmitting a probe packet to the remote receiving node at the second logical data rate;

determining a second effective user data rate based on a determination whether the remote receiving node received the probe packet; and

changing the first logical data rate to the second logical data rate based on the second effective user data rate.
