Today there are several ways by which a wireless internet service provider can deliver service. It is known as Bluetooth, Wi-Fi & WiMax. Bluetooth is an open wireless protocol for exchanging data over short distances from fixed and mobile devices. It is used to creating Personal Area Network (PANs). It is also knows as 802.15 standard of IEEE and wireless PAN. WiMax network can be built around an entire city, instead of providing limited coverage area while as Wi-Fi provides the services in broadband LAN. However, it does not meet QoS requirements for real-time data traffic applications such as voice and video transmissions.
