How broadband works? WIMAX,DSL,CABLE

WiMAX is the latest technology in wireless communication. IEEE (Institute of Electronics and Electrical Engineers) has standardized WiMAX as 802.16 (d/e). WiMAX platform supports triple play (Broadband Internet & Data, Voice, and Multimedia service). Customers can opt for either one or all services at the same time using a single CPE (Consumer Premises Equipment). Few attributes of WiMAX project are:
The CPE operates on 3.5GHz spectrumThe CPE first communicates with the nearest Access Point, and after communicating authentication codes/keys, it establishes a communication bondThe bond stays live until the CPE is powered offWireless signal can go up to 2.5 miles in a non line of sightSupports triple playIn terms of connectivity with Customer over WIMAX Ethernet interface, Layer 2 (Point to Point, Point to Multipoint) and Layer 3 VPN or a combination of both services are supported.

DSL or xDSL,(Digital Subscriber Line) is a family of technologies that provide digital data transmission over the wires of a local telephone network. The digital transmission is achieved through a customer premises equipment (CPE) usually a DSL modem, and DSLAM (Digital Subscriber Line Access Multiplexer) at PSTN office. DSLAM separates the voice frequency signals from high speed data signals, and routes data to ISP.

To activate cable broadband services you require an EMTA – embedded multimedia terminal adapter which
has an Ethernet port and connects you to the providers LAN through your computer. With cable broadband
you can experience true broadband surfing and download your favorite music and browse internet at an
incredibly fast speed.
