all completely covered in small scales. All the adults in the Lepidoptera family start off as a caterpillar‚ which resembles a worm‚and grow up to be either a moth or a butterfly. The butterflies have very thin antennas and tend to fly during the day‚ while the moths have feathery antennas and are attracted by night lights. Orthoptera- Examples are: Gryllus campestris‚ Stenopalmatus fuscus and Schistocerca gregaria. These insects have large hind legs‚ used especially for jumping. They have hidden

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

ARTIFICIAL SATELLITES INTRODUCTION: An Artificial Satellite is a people-made machine that orbits a variety of other objects in space. Many Artificial Satellites orbit the Earth to gather information about the universe‚ to predict the weather‚ to help with the navigation of ships and planes‚ to assist in telephone calls over the ocean‚ to observe the Earth‚ and as a tool to improve military activities. Though Artificial Satellites have mostly orbited Earth‚ some have orbited the moon‚ the sun

Anatomy of contemporary GSM cellphone hardware Harald Welte April 16‚ 2010 Abstract Billions of cell phones are being used every day by an almost equally large number of users. The majority of those phones are built according to the GSM protocol specifications and interoperate with GSM networks of hundreds of carriers. Despite being an openly published international standard‚ the architecture of GSM networks and its associated protocols are only known to a relatively small group of R&D engineers

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
