New Roku XR will add 802.11n Wi-Fi upgrade to cheap media streamer

Stability and antenna more important than 802.11nVideo streams are 4.5 Mbps at best. Even 802.11b can handle it so long as you have a very stable stream with no radio interference. In come cases, 802.11b is more resilient against interference because each pulse of data occupies a longer...

ZigZag Decoding: Combating Hidden Terminals in Wireless Networks

This paper presents ZigZag, an 802.11 receiver that combats hidden terminals. ZigZag exploits 802.11 retransmissions which, in the case of hidden terminals, cause successive collisions. Due to asynchrony, these collisions have different interference-free stretches at their start, which ZigZag uses to bootstrap its decoding. ZigZag makes no changes to the...

An Approach to WLAN Security

802.11b's low cost of entry is what makes it so attractive. However, inexpensive equipment also makes it easier for attackers to mount an attack. "Rogue" access points and unauthorized, poorly secured networks compound the odds of a security breach. The 802.11b standard shares unlicensed frequencies with other devices, including Bluetooth...

Energy Savings by Intelligent Interface Idling in 802.11 Based Wireless Networks

This paper proposes and analyzes a new interface idling mechanism for improving carrier-sense energy expenditure of IEEE 802.11 based wireless network interfaces. A novel protocol state analysis technique is developed for detecting time windows during which a node consumes energy due to erroneous carrier sensing. During this window, energy savings...

Extended Abstract: Understanding the Effect of Access Point Density on Wireless LAN Performance

This paper presents a systematic experimental study of the effect of inter-cell interference on IEEE 802.11 performance. With increasing penetration of WiFi into residential areas and usage in ad hoc conference settings, chaotic un-planned deployments are becoming the norm rather than an exception. These networks often operate many nearby access...

An Experimental Study on the Capture Effect in 802.11a Networks

In wireless networks, a frame collision does not necessarily result in all the simultaneously transmitted frames being lost. Depending on the relative signal power and the arrival timing of the involved frames, one frame can survive the collision and be successfully received by the receiver. Using the IEEE 802.11a wireless...
