Network hardware manufacturer US Robotics launched a firmware upgrade at the WLAN show in London on Tuesday that boosts the performance of its 802.11g wireless products to 125Mbps.
The 54Mbps 802.11g standard, which was ratified last year, has already been boosted to around 108Mbps by the majority of wireless hardware manufacturers but USR is one of the first to further increase this speed. In January, Broadcom updated to 125Mbps, and manufacturers such as Buffalo Technology, Belkin, and Linksys are expected to release equivalent updates in the very near future.
Peter Blampied, European director of sales and operations at US Robotics, said in a statement that the company will offer a free firmware and driver upgrade to existing 802.11g customers from its Web site: "Customers purchasing US Robotics wireless solutions today should be assured that they are buying 125Mbps-capable products,” he said.
Earlier this year, Synergy Research Group reported that revenue for wireless networking gear reached $2.5bn in 2003, up about 40 percent on the previous year.
Market-research firm Allied Business Intelligence said that next year the market will change again as shipments of dual-band 802.11a/g networking products surpass those of 802.11g equipment, driven largely by multimedia applications. By 2009, the company said, 95 million Wi-Fi networking equipment devices will be shipped.
The 802.11g wireless standard is a follow-on to 802.11b, running at a higher speed and offering greater security. The two specifications, which are interoperable, function on the 2.4GHz frequency, along with microwave ovens and Bluetooth products. The 802.11a standard operates on the 5GHz spectrum, reducing interference problems; it is interoperable with the "g" specification but not with "b."

Please get facts straight. (a) is not interoperable with (b) or (g). Some (b) devices reduce the effectiveness of (g) devices and some devices are (a) and (b) or (a) and (g). Now what did you mean by interoperable?
6 Apr 04 23:38 ReplyAlso, there was no mention of how many of the 3 interference free 2.4GHz channels are used up by the usr devices...
Yes but it's never going to achieve 125mbps, its not really that speed is it. Why can't they say what it is, my 512 connection does not transfer at that rate but I pay for a 512 connection, why can't they design a 125mbps connection and market it at a guaranteed d/l rate of 90mbps?!!!
7 Apr 04 00:47 ReplyIs it not a half duplex standard? meaning actual data rate will be half of 125mbits? (62.5mbits). Also you will have to be close to get the max speed.
14 May 04 11:27 ReplyNo, Half duplex just means that data can only be sent one way at a time.
29 Sep 04 11:40 Reply125Mbps is how fast the PHY (Physical Layer) can spew bits in one direction.
62.5Mbps is the "ideal" bandwidth you'd see if you going full pelt in both directions, but the actual bit-rate would be lower due to latencies in the equipment.
