Bluetooth Technology
Bluetooth is a wireless technology that provides users freedom from wired connections, enabling links between mobile computers, mobile phones, portable handheld devices, and connectivity to the Internet. The Bluetooth technology was developed by a Swedish company Ericsson and therefore, the term was named after a local hero Harald Blatand II Bluetooth. This technology was initially developed for mobile telecommunications but is now used in many other forms of digital data communications as mentioned earlier. The current focus is now on the integration of wireless networking with Bluetooth. The term wireless networking refers to technology that enables to or more computers to communicate using standard network protocols, without the network cabling. Wireless networking and Bluetooth both use the same standard (IEEE 802.11) and use the same frequencies for carriers. The IEEE 802.11b is the most common and established wireless network protocol in use today. As with Bluetooth, wireless networking also promises high mobility, increased convenience and it does not require any expensive cabling infrastructure. For the technology deployment of both technologies, they require a low-cost transceiver chip in to be included in each device.
The scope is determined with the knowledge of anticipated number of users, their bandwidth consumption, and some idea of their roaming frequency. This is matched with the physical elements of the site. After that, this is accomplished with a site survey, which involves taking a look at the physical layout of your office space. The optimal placement and density of access points to maximize client connectivity and bandwidth are then determined. During the early days, wireless networking wasn't accepted for three reasons. They are: limited bandwidth, radio interference from other devices and networks, and security concerns. For example, even though 802.11b performs at the rough equivalent to 10Mbps wired Ethernet, overhead, configuration, and security factors can cut the actual throughput to 4 to 7Mbps. That speed is fine for supporting text-based documents transmissions, but not for applications such as multimedia streaming. Interference issues worsen as Bluetooth and 802.11b both use the 2.4GHz radio spectrum. Corporate installations cannot limit the placement and presence of Bluetooth as devices as used together. Other interference sources for 802.11b are legacy wireless systems and home control devices. Because 802.11b can extend 100 to 150 feet inside buildings and up to 1000 to 1500 feet outside, if your office or home neighbor is using the same wireless devices in the 2.4GHz spectrum
