A WAN (Wide-Area Network) is a collection of LANs—or a network of networks. Get answers about WAN optimization and technologies. Read more What is OFDMA? Orthogonal frequency-division multiple access (OFDMA) is a technology in Wi-Fi 6 that improves wireless performance. Learn about how it ...
The saturation throughput of 802.11 wireless LANs is investigated by the developed method. The obtained numerical results are validated by simulation and lead to the change of the existing idea of the optimal access strategy in the saturation conditions. 展开 ...
Wireless LANs have become popular in the home due to ease of installation, and the increasing to offer wireless access to their customers; often for free. Large wireless network projects are being put up in many major cities: New York City, for instance, has begun a pilot program to provide...
Wireless LANs based on IEEE 802.11 use a distinct frame structure and a complex data link layer protocol. We'll talk about 802.11 shortly, but for now we should just note that the Illustrated Network uses USB-attached wireless NICs, and few wireless sniffers support these types of adapters. ...
