Reasons For Bluetooth Domination Over Other Wireless Technologies
One of the most important directions in current computer technologies is the development of wireless connections between various devices. Nowadays, there exist several technologies and protocols, which can be used for wireless connection of different devices. These technologies include Infrared Data Association (IrDA), HomeRF and Bluetooth. IrDA and HomeRF have emerged around the same time with Bluetooth, at the end of 1990's. However, around 2000 IrDA and HomeRF technologies have started to become obsolete, due to not being able to compete with the powerful Bluetooth technology features.
It was designed originally only for radio, with no plans of building wireless networks, based on it. However, soon after there emerged wireless networks, which have formed a new concept of the modern Blue tooth-network.
The purpose of this standard and technology is to connect any device with other devices, located in close proximity, regardless of the brands of the connected devices.
The technology makes it possible to obtain a number of previously inaccessible functions and services, such as a Handsfree device for using a cell phone without taking it out from a pocket or suitcase, printing from a printer without a cable, using your phone as an electronic ticket or a payment method, where the price of a service can be automatically withdrawn from your account, etc.
It is also a new standard of modern wireless data transmission technologies, which uses radio waves at a close range of 10-20 meters (33-66 feet), replacing cables for connection of various electronic devices. Presently almost the obsolete IrDA technology is also capable of wireless data transmission, but only in the range of 1-2 meters, which is enough to use it for remote controls, but not enough for many other applications.
It offers great opportunities for a wide variety of devices and applications. You can connect with one another, any devices, which have a built-in Bluetooth micro-chip. Bluetooth is a standardized technology; hence there is no problem of incompatibility between devices from competing companies. The technology also offers wireless access to Local Area Network (LAN), Public Switched Telephone Network (PSTN), a network of mobile phones and Internet.
It allows the connection of electronic devices and wireless communication over a short range, with a special network, called piconet. As many as seven devices can be connected in one piconet network. If there are more than seven devices, there will automatically form an additional piconet network. Furthermore, each device can simultaneously belong to multiple networks. These networks are established dynamically and automatically, as devices enter and leave connection with nearby devices.
The competing technologies, including IrDA and HomeRF, could compete with many of the powerful Bluetooth features. Thus, nowadays Bluetooth has become an absolute leader of wireless networking of various electronic devices.
