Link margin improvements using a variable physical layer symbol rate

A wireless communication system, comprising:

• a source wireless communication device that communicates wirelessly using a short-range wireless communication link, the source wireless communication device is configured to:
• transmit data using and asynchronous connection-oriented logical transport (ACL) of the short-range wireless communication link;
• determine an amount of time that has elapsed since a high throughput event on the ACL of the short-range wireless communication link;
• based on determining the amount of time, decrease a first physical layer (PHY) symbol rate of the ACL to a second PHY symbol rate, wherein a link margin between the source wireless communication device and a second wireless communication device is increased based on altering the first PHY symbol rate of the ACL to the second PHY symbol rate;
• and
• transmit data using the ACL and the second PHY symbol rate.

A wireless communication device, comprising:

• a wireless communication interface that communicates wirelessly using a short-range wireless communication link;
• and
• a processing system comprising one or more processors in communication with the wireless communication interface, wherein the processing system is configured to:
• transmit data using and asynchronous connection-oriented logical transport (ACL) of the short-range wireless communication link;
• determine an amount of time that has elapsed since a high throughput event on the ACL of the short-range wireless communication link;
• based on determining the amount of time, decrease a PHY symbol rate of the ACL to a second PHY symbol rate, wherein a link margin between the wireless communication device and a second wireless communication device is increased based on altering the PHY symbol rate of the ACL to the second PHY symbol rate;
