Abstract
A wireless data access system is provided to ameliorate bursty traffic occurring in a radio communications link such as a WiFi, WiMAX, 3G or cellular telephone link to a wireless network access device. A data traffic event is detected relating to traffic in the link. The traffic event may be a traffic burst exceeding a predetermined threshold. Based on detecting the data traffic event, a free-space optical communications link is established to the network access device to handle the traffic burst. The established radio link may be used to set-up and coordinate the free-space optical link.
Claims16
A method performed in a wireless access point for providing wireless network services, the method comprising:
- establishing a first communications link between a first network access device and a second network access device via the wireless access point, the first and second network access devices being independent wireless network access devices, the first communications link comprising a first wireless radio link between the first network access device and the wireless access point, and a second wireless radio link between the second network access device and the wireless access point;
- detecting at the wireless access point a data traffic event relating to traffic in the first communications link;
- based on detecting the data traffic event, establishing a direct free-space optical communications link from the first network access device to the second network access device, the direct, free-space optical communications link bypassing the wireless access point;
- and
- at the wireless access point, coordinating the direct, free-space optical communications link between the first network access device and the second network access device, the coordinating using the first wireless radio link between the first network access device and the wireless access point, the coordinating further using the second wireless radio link between the second network access device and the wireless access point.
A non-transitory computer-usable medium having computer readable instructions stored thereon for execution by a processor to perform a method performed in a wireless access point for providing wireless network services, the method comprising:
- establishing a first communications link between a first network access device and a second network access device via the wireless access point, the first and second network access devices being independent wireless network access devices, the first communications link comprising a first wireless radio link between the first network access device and the wireless access point, and a second wireless radio link between the second network access device and the wireless access point;
- detecting at the wireless access point a data traffic event relating to traffic in the first communications link;
- based on detecting the data traffic event, establishing a direct free-space optical communications link from the first network access device to the second network access device, the direct, free-space optical communications link bypassing the wireless access point;
- and
- at the wireless access point, coordinating the direct, free-space optical communications link between the first network access device and the second network access device, the coordinating using the first wireless radio link between the first network access device and the wireless access point, the coordinating further using the second wireless radio link between the second network access device and the wireless access point.
