Wireless
Wireless technology for Internet access is rapidly spreading throughout the world. It will not be long until every corner of the globe is connected to the Internet via Wi-Fi. Portable laptop computers are produced, manufactured and released in a steady stream with upgraded 802.11 a/b/n connectivity chipsets, enabling technical and non-technical users to connect to the Internet via speedy wireless connections. Bluetooth technology allows a wireless protocol for connectivity and is specifically designed for electronic applications less than 30 feet in distance from the host site.
Wireless connectivity is used by professionals in IT, in large business organizations and for home use. Connecting to the Internet with a wireless connection is fast becoming the preferred way to access the Internet. The convenience of wireless connections and the practicality of the initial set-up and maintenance of wireless services is an industry that is growing and developing rapidly as Bluetooth technology expands. Most peripherals can be connected wirelessly to a desktop computer or notebook using Bluetooth technology, creating a cleaner and more practical work environment for all users. Understanding wireless security encryption and developing a secure system of connectivity is essential to prevent data theft and establishing sound security measures within wireless connection.
This is the first article on the Bluetooth Technology by Nupur Mittal. Blue tooth has been regarded as a new wave in the IT sector from the day of its origin. Blue tooth is continuing its success story. Toshiba introduced blue tooth in September 2000 to consumers for $ 199. The new technology is supported by SIG (Special Interest Group). SIG founded in 1998 consists of 2000 members who have access to the Blue tooth specifications (information needed to make a blue tooth product). The SIG works to promote the Blue tooth technology and consists of members like IBM, Intel,…
This is the first article on the Bluetooth Technology by Nupur Mittal. Bluetooth is a high-speed, low-power microwave wireless link technology, designed to connect phones, laptops, PDAs and other portable equipment together with little or no work by the user. Connective convenience Unlike infra-red, Bluetooth does not require line-of-sight positioning of connected units. The technology uses modifications of existing wireless LAN techniques but is most notable for its small size and low cost. The current prototype circuits are contained on a circuit board 0.9cm square, with a much smaller single chip version in development. The cost of the device is…
This article discusses about the differences between Bluetooth and 802.11b Wireless LANs, Co-existence of Bluetooth & Wi-Fi and Advantages & Disadvantages. 1) Bluetooth has lower distance range (less than 30 feet) than 802.11b (up to 200 feet). Therefore, you would need many more access points to cover the same area of an office. Simple mathematics will show that you may need as many as 20-50 times the number of access points 2) Bluetooth has generally lower speed than that of 802.11b wireless LANs. 3) Bluetooth components (chips and radios) and device adapters are cheaper than wireless LAN components and adapters. 4)…
This article discusses about various Bluetooth Technology Models & Application in the market and Bluetooth in Future. Bluetooth Technology Models & Applications HomeRF like Bluetooth is a specification for connectivity and mobility in a home-like environment. HomeRF Working Group has developed a specification for wireless communications in the home called the Shared Wireless Access Protocol (SWAP). The Federal Aviation Administration (FAA) and other aviation regulatory bodies worldwide are currently reviewing the use of Bluetooth products on private and commercial aircraft. In the U.S. the FAA is the governing body to grant approval for Bluetooth product use on aircraft; therefore, we…
