However, while some of these devices adopt the same frequencies they depend upon different standards and cannot talk to each other. Wi-Fi, in view of its potentialities can be regarded as something still large, a set of open spectrum technologies that could rewrite the rules of the airwaves, reversing a century of regulatory policy and enabling an explosion of new wireless devices and services. At the background of the Wi-Fi phenomenon, an increasing cadre of open spectrum activists is presently striving for a thorough change in the telecoms regulation.
However, the airwaves were too limited to be shared by all, and this is the fact that has kept the venerable landlines alive for long. (Anderson, 2003) Bluetooth implies to the technology standard that applied the short-range radio links rather than of cables to connect portable and/or fixed electronic devices. The standards of Bluetooth form a homogenous structure for communication between wide ranges of devices with minimum user effort. (Ganguli, 2002) Bluetooth is a cable-replacement technology.
Bluetooth originally formulated by Ericsson is a standard to represent small, cheap radio chip to be plugged into computers, printers, mobile phones, etc. A Bluetooth cheap is structured to facilitate intake of information without cables, then transmitting it at a special frequency to a receiver Bluetooth chip that will then accord information received to the computer or mobile as the case may be. It also facilitates transfer of data from a mobile phone to a printer or even from a printer to another printer. The name Bluetooth originally conceived after the Danish Viking and Kind, Harald Blatand, being translated as Bluetooth in English.
He lived in the later part of 10th century and had a wide fascination for eating Blueberries. As a result his teeth became stained with the color. (What is Bluetooth? ) Bluetooth generated a single synchronization protocol to deal with the end-user problems coming out of the proliferation of several mobile equipments such as smart phones, smart pagers, P. D. As, handled PCs, copiers, printers, notebooks, and many future digital appliances at home- that required to maintain data consistent from one device to another.
The bluetooth solutions have been conceived to almost automatically synchronize mobile devices when end users enter their offices or home. Ever since its inception in 1998, the interest in Bluetooth has increased tremendously. Bluetooth is conceived of as the high-speed, low-power microwave wireless link technology, structured to link the phones, laptops, PDAs and other portable equipment together with little or no work by the user. (How Bluetooth Technology works) However, it is not necessary in case of the Blue-tooth to position the connected units.
The technology applies variation of the prevailing wireless LAN techniques. It is also remarkable for its miniature size and minimal cost. The technology aims at embedding tiny, inexpensive, short-range transceivers into the electronic instruments those are prevailing presently. The radio is applicable on the globally-available unlicensed radio band. The modules of Bluetooth can be either built into electronic devices those are available presently. The Bluetooth connections can be established from point to point or multipoint.
The maximum range is 10 meters, however, can be spread over 100 meters by raising the capacity. They are also safeguarded from radio interference by varying their frequencies randomly up to a maximum of 1600 times per second, the technique termed as frequency hopping. (How Bluetooth Technology works) WiMAX, the acronym of the World Interoperability fro Microwave Access, depending upon the IEEE 802. 16 standard is anticipated to make possible real broadband speeds over the wireless networks at a cheaper cost so as to ensure wide accessibility.
This is considered to be the real wireless standard at present that ensures the true broadband speeds and assist them the vision of pervasive connectivity a reality. WiMAX presently have two primarily applications such as point-to-multipoint broadband access to homes and businesses, while the mobile WiMAX entails he complete mobility of the cellular networks at real speed of the broadband. The fixed as well as the mobile applications of WiMAX are structured to assist delivering of unique, high-output broadband wireless service at a cheaper price.
The Mobile WiMAX depends upon OFDMA i. e. Orthogonal Frequency Division Multiple Access technology that has inherent advantages in throughput, latency, spectral efficiency, and advanced antennae support; primarily enabling it to provide higher performance than present day wide area wireless technologies. WiMAX represents a scope for worldwide connectivity in highly improved mobile market potentialities and developing nations. (WiMAX Broadband Wireless Technology Access)
EV-DO, the acronym for Evolution, Data Only is considered as one of the major Third Generation, or 3G, wireless standards. The contemporary standard is termed as W-CDMA. The standard is structured to ensure voice and high speed mobile data using the cellular approach already tested to function in mobile phone networks. The lack of bandwidth however, is taken to be the biggest hurdle in implementation of the high speed wireless networks. (What is EVDO? )
