624 results about "IEEE 802" patented technology

IEEE 802 is a family of IEEE standards dealing with local area networks and metropolitan area networks. The IEEE 802 standards are restricted to networks carrying variable-size packets, unlike cell relay networks, for example, where data is transmitted in short, uniformly sized units called cells. Isochronous networks, where data is transmitted as a steady stream of octets, or groups of octets, at regular time intervals, are also beyond the scope of the IEEE 802 standards.

Secondary link access to a mobile soft access point multi-link device

An IEEE 802.11 wireless protocol which allows a non-Access Point Multi-Link Device (non-AP MLD) to access a soft AP MLD (e.g., an MLD which is not configured for Simultaneous Transmit and Receive (STR)) over a conditional link (Link2) when the primary / basic link (Link1) is occupied by another STA / MLD. Additional frame exchanges are described between MLDs to facilitate the Non-AP MLD's ability to accessing the soft AP MLD. Utilizing the approach can increase overall network throughput in a single BSS or OBSS.
