The Effects of Adjacent Channel Rejection and Adjacent Channel Interference on 802.11 WLAN Performance

Tags:
802.11

Overview The escalating deployment of wireless networking technology as well as other wireless technologies in the same unlicensed spectrum is rapidly increasing the radio frequency (RF) interference for Wi-Fi (802.11) products, threatening the data throughput performance of wireless local area networks (WLAN). At the same time, the market is demanding higher data throughput rates for new WLAN applications like multimedia audio and video, streaming media, voice over WLAN, and others that require quality of service (QoS) capabilities and low packet error rates. This white paper analyzes the sources of adjacent channel interference (ACI) and the radio design practices that can improve a WLAN´s adjacent channel rejection (ACR) for better overall performance.

3GSM: "Fastest" cellular technology gets alliance

However, as yet no tier-one mobile operators have made a TDD move, even though they have the spectrum to use the technology, which is a standardised variant of the better-known 3G. Any talk about faster data rates has typically focused on an...

Peter Cochrane's Blog: The search for spectrum

We have already adapted our work patterns to sit in a room full of people with laptops using Wi-Fi, or mobile phones, all operating interference-free. Every time I look at the allocation of radio spectrum channels I go to a brightly coloured wall...

Peter Cochrane's Uncommon Sense: Wireless everything

Adopting this technology as the dominant mode for the future would mean the disassembling today's radio spectrum rules in terms of frequency and power allocations. We have principally avoided interference by allocating specific frequencies of...

Peter Cochrane's Uncommon Sense: Mobile guesses

Only the allocation of spare frequency space, power limiting specifications to keep radio operation safe and interference free, and some really smart self-organising software. First, we have so far, only used up to 10 per cent of the frequency...
