Abstract
A technique is disclosed to schedule frame transmissions in a wireless network utilizing scheduled TDMA by synchronizing clocks in repeater and backhaul access points.
Claims19
A system of regulating wireless traffic between a plurality of backhaul access points and a plurality of repeater access points, each of the repeater access points to communicate with at least one of the backhaul access points over a first frequency range, at least one of the repeater access points to communicate with a client device over a second frequency range different from said first frequency range, said system comprising:
- a central controller communicatively coupled to each of said backhaul access points, said central controller to schedule wireless transmissions between said repeater access points and said backhaul access points based on estimated signal conditions at designated receivers of said wireless transmissions, the central controller to enable said client device to communicate with a said backhaul access point over a multi-hop connection through said at least one of the repeater access points;
- the central controller further to
- determine which wireless transmissions between said repeater access points and said backhaul access points that can be executed simultaneously;
- and
- schedule said wireless transmissions to maximize a number of simultaneous wireless transmissions between said repeater access points and said backhaul access points.
A method comprising:
- wirelessly communicating between a first backhaul access point and a first repeater access point using a first frequency range;
- wirelessly communicating between a second backhaul access point and a second repeater access point using said first frequency range;
- wirelessly communicating between the first repeater access point and a first client device using a second frequency range different than the first frequency range, such that the first client device communicates with the first backhaul access point over a first multiple-hop connection using the first said repeater access point;
- wirelessly communicating between the second repeater access point and a second client device using said second frequency range, such that the second client device communicates with the second backhaul access point over a second multi-hop connection using the second said repeater access point;
- scheduling wireless transmissions between said first backhaul access point, said first repeater access point, said second backhaul access point, and said second repeater access point based on estimated signal conditions at designated receivers of said wireless transmissions;
- determining which wireless transmissions between said repeater access points and said backhaul access points that can be executed simultaneously;
- and
- scheduling said wireless transmissions to maximize a number of simultaneous wireless transmissions between said repeater access points and said backhaul access points.
An apparatus, comprising:
- a processor;
- a memory communicatively coupled to said processor, said memory comprising executable code stored thereon, said processor being configured to, upon execution of said executable code:
- receive signal strength information from a plurality of repeater access points and backhaul access points;
- estimate wireless signal conditions at said repeater access points and said backhaul access points;
- schedule wireless transmissions between said repeater access points and said backhaul access points based on said estimated wireless signal conditions;
- determine which wireless transmissions between said repeater access points and said backhaul access points that can be executed simultaneously;
- and
- schedule said wireless transmissions to maximize a number of simultaneous wireless transmissions between said repeater access points and said backhaul access points.
