by adding multiple-input multiple-output (MIMO) and 40 MHz channels to the physical (PHY) layer‚ and frame aggregation to the MAC layer. MIMO is a technology which uses multiple antennas to coherently resolve more information than possible using a single antenna. Two important benefits it provides to 802.11n are antenna diversity and spatial multiplexing. 802.11g The 802.11g specification is the most recent of the Wi-Fi specs to be approved and is currently the most commonly implemented

radio by Nikolai Telsa in the 1880s. When these two great technologies are combined it made the cell phone. People who needed mobile-communication devices had radio telephones in their cars. In the radio-telephone systems‚ there was one central antenna tower per city‚ and perhaps 25 channels available on the tower. In your car you needed a powerful transmitter. Not everyone could have a radio telephone because there were only 25 channels available per city. Each cell phone has a cellular system

ABSTRACT The aim of technology is to make products in a large scale for cheaper prices andincreased quality. The current technologies have attained a part of it‚ but themanufacturing technology is at macro level. The future lies in manufacturing productright from the molecular level. Research in this direction started way back in eighties. At that time manufacturing at molecular and atomic level was laughed about.But due toadvent of nanotechnology we have realized it to a certain level. One such

example‚ Tampa International airport offers free Wi-Fi in many areas of the airport. Signs direct users to “hotspots” serving travelers iternet access between flights. Hotspots are within 300 feet from an antenna broadcasting a signal. This service is limiting since a person cannot move far from the antenna without losing connection. The biggest downside to this technology is security—it has none. Therefore‚ a person would never want to pass personal‚ private‚ or sensitive information over a Wi-Fi network

As such antennas made with a Quaker Oats container and aluminum foil can intercept radio transmissions if they do not encrypt or otherwise secure the source of the communications. This is a primary risk of wireless communications that many users fail to appreciate

Contents 1. Introduction Almost 200 years after Charles Darwin’s death his theory of the „Survival of the Fittest“‚ that creatures adapt to their environment‚ is still omnipresent. Putting this theory to the business world‚ one can see that the companies are also under a natural selection. Only the best adapted companies can take on the challenge of our more and more globalized world in the long run. In this process‚ it is clear that some companies can handle the selection better than

Copper vs Fiber Some advantages of Copper Cabling are Power over Ethernet this gives you the ability to power phones‚ surveillance cameras‚ Wireless Access Points‚ and many other devices right through the networking cable itself. That means that you don’t have to schedule an electrician in to run power to your surveillance cameras to power them. Another advantage is the ability to have an emergency power supply that will continue powering mission critical devices even if your electricity goes
