Prism3 Chipsets?

Filed under: Wireless — Nathanxr @ 1:03 am

Hi everyone, I did a brief search of the forum and didn’t return any results but I was wondering if anyone here could point me in the right direction?
I want to get a b/g (maybe a as well) pc card for my laptop, but I have particular requirements. I’d like a Prism 2.5 or 3 chipset, good transmit /recieve power and a jack for an external antenna… I’m having alot of trouble finding something like this.
The reason I want a prism chipset is for application support and monitor mode.

Any suggestions or ideas for a product I should look at?
Thanks

Nath

Interference-Free WLAN Delivers Robust Mobile Telephony

Filed under: Wireless — evilbunny @ 10:04 am

While many vendors are trumpeting advances in voice over WLAN (also known as VoWiFi or wVoIP), they are nonetheless working against fundamental problems inherent in the IEEE 802.11 standard that underpins most wireless LAN technology—and therefore most wVoIP.

Extricom Ltd., an Israeli R&D company, claims to have overcome these problems while remaining compliant with all current flavors of 802.11—.11b, .11a, and .11g. The limited number of RF channels, interchannel interference from adjacent channels, and restricted range and capacity are all dragons Extricom technology has slain, according to CEO Gideon Rottem.

The result: a wireless LAN architecture highly friendly to voice traffic.

Helium Wireless Recon: A Sneak Peek

Filed under: Wireless — evilbunny @ 11:14 am

Over the past few months, I’ve been testing Helium Networks’ new Wireless Recon system for performing radio frequency (RF) site surveys and engineering wireless LANs. Helium had been referring to this product as Rollabout during the beta development phase while I’ve been testing. The commercial release of the Wireless Recon system, which includes some enhancements, was announced this at Interop in Las Vegas

The Wireless Recon system consists of SiteSense software that installs on a wireless-equipped laptop that you connect via a cable to their SiteScout cart (which Helium refers to as “mapping hardware”). The cart includes three wheels and a platform for holding the laptop. The SiteScout unit is easy to push around and conveniently folds up and fits within a sturdy case suitable for checking on airline flights.

LAN Dressed as MAN: Metro-Zone 802.11 Wireless

Link To Report

By Gabriel Brown | 10.27.04

Public-access 802.11 wireless LAN is a riddle � we’ve all used it in hotels, airports, or at conferences, and found it to be valuable. But in spite of this, the business of deploying and operating hotspots is fraught with cost and undermined by users that don’t like paying much, if anything, for WiFi.

Personally, I’ve all but abandoned paid WiFi hotspots since 3G data cards (300 kbit/s downstream, 64 kbit/s upstream) arrived in London (see Review: Vodafone’s 3G Data Card). Not only do I save a little money, but I also get to choose where I go to sip tea and access the Internet.

Intel to produce 802.11g WLAN module by year end

Filed under: Wireless — evilbunny @ 9:11 am

Intel will begin mass-producing its long-awaited 802.11g wireless networking module at the end of this month, a senior Intel Asia Pacific executive has said.

The Pro Wireless 2200BG unit will be offered alongside Intel’s existing 802.11b and 802.11a/b products, all components of the chip giant’s Centrino platform.

The new unit is based on the second generation of ‘Calexico’, Intel’s wireless chipset architecture. Calexico 2 comprises two chips rather than the previous generation’s four.

Tests confirm Atheros’ Super G degrades rival WLANs

Filed under: Wireless — evilbunny @ 9:09 am

Broadcom’s allegation that 802.11g Wi-Fi products based on chips developed by its rival, Atheros, will degrade the performance of nearby wireless networks appears to have been verified by independent tests.

Tim Higgins of web site Small Net Builder carried out a comprehensive series of tests to see if
Atheros’ Super G technology, which promises to double the range of WLANs built out of Atheros kit, interferes with adjacent networks not based upon the technology.
