Wireless communication protocols have evolved rapidly since the introduction of 802.11 Legacy over a decade ago. Over the last 10 years we have seen efficiency and performance increases on all fronts‚ which have lead to greater range and faster transfer speeds. With Legacy 802.11 protocols‚ speeds maxed out at around 2 Mbits/sec and indoor range was only about 20 meters. In 1999‚ the 802.11 protocol got a couple of amendments in the form of 802.11a and 802.11b. Both offered higher speeds and slightly

also serves as my access point to the network provider. The access point is where your wireless signal is turned into a digital signal and sent through a cable. The last two pieces are antennas and repeaters. Antennas and repeaters allow you to extend the range of your wireless network. First you place an antenna to attempt to reach all the client systems within your area of coverage. If you have outlying systems that are not within the gain of the antennae you can use a repeater. It acts as a

is a wireless identification. Normally the RFID system comprises of two main parts: RFID Reader and RFID Tag. RFID Reader is an integrated or passive network which is used to interrogate information from RFID tag. The RFID Reader may consist of antenna‚ filters‚ modulator‚ demodulator‚ coupler and a micro processor.

Radio Waves In the modern society‚ radio is the most widely used medium of broadcasting and electronic communication : it plays a major role in many areas such as public safety‚ industrial manufacturing‚ processing‚ agriculture‚ transportation‚ entertainment‚ national defense‚ space travel‚ overseas communication‚ news reporting and weather forecasting. In radio broadcasts‚ they use the radio waves which can be both microwaves and longer radio waves. These are transmitted in two ways: amplitude

The types of language the author used made me more interested in the book because they would appeal to me more because they seemed more scientific. As well as this the author used many acronyms like HAB (habitation module). The beginning of this text made me want to keep reading because I thought he died By getting impaled on a radio antenna that was his only way to contact earth and I wanted to

If each cell is to offer capacity that is 90% of perfect scheduling‚ find the maximum number of users that can be supported per cell where omnidirectional antennas are used at each base station. c. What is the blocking probability of the systems in (b) when the maximum number of users are available in the users pool? d.

RFID based Library Management system (LMS) would allow fast transaction flow for the library and will prove immediate and long term benefits to library in traceability and security. The proposed system is based on UHF RFID readers‚ supported with antennas at gate and transaction sections‚ and library cards containing RFID-transponders which are able to electronically store information that can be read / written even without the physical contact with the help of radio medium.
