Wireless Network Standards University of Phoenix In 1997 802.11 was finally approved after a 7 year wait on the IEEE though this standard would only allow transmit ion rate of 1 Mps to 2 Mps do to the slow transfer rates soon after they came out with 802.11b providing a new standard that can run at 5.5 Mps to 11 Mps and data is to be sent via ISM band up from the 1 Mps to 2Mps standard and can broadcast up to 375 feet though the speeds got slower the further away the devices were away. The 802.11a came out at the same time as 802.11b the 802.11a standard that could run at bandwidths up to 54 Mps though this standard was more expensive do to the fact that they could not use semiconductors in the CMOS. The CMOS had to be made from gallium or germanium so increased the devices cost. The increase in bandwidth was a trade of on broadcasting distances though and was brought

Unformatted text preview: down to 100 feet under the U-NII unlicensed frequency range. Then the 802.11g was developed which combined the 802.11a and the 802.11b standards to run at 54 Mps and get the range back to 375 feet using the ISM frequencies. The 802.11n standard should run at a bandwidth from 100 to 500 Mps. The 802.11 was approved in October 2009 by the IEEE. I can see were standards are beneficial in the market place and for the consumers so that they have a product that is complaint and can work with other products and in the market place having cheaper and compatible product will increase sales and competition. I do think that standards can stifle new products and technology that do not fit the standards or might not even be pursued because of them. The IEEE from reading tend to take longer to ratify something than it takes for the technology to reach the next step....
