LMDS (Local Multipoint Distribution Service) is a broadband wireless point-to-multipoint specification utilizing microwave communications. LMDS operates on FCC licensed frequencies. The FCC divided the United States into 493 BTA's (Basic Trading Areas) and auctioned the rights to transmit on the LMDS bands in each of those areas to LMDS service providers. Each BTA is licensed to two LMDS service providers. The LMDS bandplan is available from the FCC at http://wireless.fcc.gov/auctions/data/bandplans/lmds.pdf. LMDS Specifications Fixed/Mobile Fixed Circuit/Packet: n/a Max Bandwidth 1.5Gb downstream, 200Mb upstream Range 4 miles Frequency 27.5GHz-28.35Ghz, 29.1Ghz-29.25Ghz, 31.075Ghz-31.225Ghz, 31.Ghz-31.075Ghz, Read More

IKE (Internet Key Exchange) is a key exchange mode for ISAKMP. IKE is used to securely exchange encryption keys as part of building a VPN tunnel. IKE supports the following encryption algorithms: DES-CBC IDEA-CBC Blowfish-CBC RC5-R16-B64-CBC 3DES-CBC CAST-CBC IKE supports the following hash algorithms: MD5 SHA Tiger IKE supports the following authentication methods: Pre-shared key DSS signatures RSA signatures Encryption with RSA Revised encryption with RSA IKE utilizes the Diffie-Hellman asymmetric cipher for key exchange. IKE is fully documented in RFC 2409: The Internet Key Exchange (IKE).

Blackberry is a wireless handheld smartphone created by the Canada based company Research In Motion. It was first introduced in 1999 in the form of a two way pager. The first Blackberry smartphone was released in 2002. Blackberry smartphones work together with mobile service providers to transmit information or data through their wireless networks. Blackberry is the second largest selling smartphone in the world, accounting for about 21% of global smartphone sales. Apart from conventional mobile telephony, Blackberry smartphones offer the following features and services: Blackberry Enterprise Server The Blackberry Read More

A web browser is a software application that enables users to access the World Wide Web (WWW) or the Internet. Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera and Safari are some examples of widely used web browsers. To do this, a web browser must provide the following capabilities: A web browser must be able to understand data protocols utilized by web servers, such as HTML and XHTML. A web browser must be able to format (or render) the output of these languages. Web Browser Protocol Support All web browsers Read More

Whenever Internet Explorer is used to browse the Internet and view pages, a copy of the most frequently visited web pages’ files and graphics are automatically stored by in the computer hard disk. As such, when a particular web page is requested, Internet Explorer just pulls the required graphics and files up from the temporary Internet files folder located in the hard disk instead of loading the entire page and its elements from the Web. This facilitates easier transition from page to page if multiple tabs are open. This also Read More

DNA computers will be the next-generation computers made of genes' building blocks. Because of their speed, miniaturization and data storage potential DNA computers are being considered as a replacement for silicon-based computers. Current DNA computer research has already proven that DNA computers are capable of solving complex mathematical equations and storing enormous amounts of data. Limitation of Silicon Chips Silicon-based computer chips have been around for more than 40 years and manufacturers have been successful in making silicon-based chips smaller, more complex and faster than their predecessors. According to Moore's Read More

A TRIAC is used in AC power control applications in order to switch high voltages over both parts of the AC waveform. As a result, TRIAC circuits are used in a number of applications that require power switching. The TRIAC was developed after the thyristor, which controls AC current over one half of the cycle. The TRIAC circuit can be visualized as two thyristors that are opposite, parallel, and have the two gates connected together with one device’s anode connected to another’s cathode. A common household device that uses the Read More
