  2. What is broadband modem • Types of broadband modem • Wired broadband modem • DSL(Digital subscriber line) • Cable modem • PLC modem • Wireless modem • Wi –Fi • Wi-max • FSO • Programming INDEX

  3. WHAT IS BROADBAND MODEM? • A modem (modulator-demodulator) is a device that modulates an analog carrier signal to encode digital information and also demodulates a carrier signal to decode the transmitted information. • The broadband modem is like an ordinary telephone modem except it connects you to a broadband service instead of a dial-up service. • The broadband modems are high speed modems.It connect internet at high speed.

  4. Types Of Broadband Modem WIRED MODEMS WIRELESSMODEMS WI-FI WI-MAX FSO • DIGITAL SUBSCRIBER LINE • CABLE MODEM • PLC MODEM

  5. WIRED BROADBAND MODEM 1 DSL (Digital Subscriber Line): - • DSL uses the existingtwisted-pair telephone lines as the access media. Over a period of time, a number of technologies (xDSL) have been introduced to provide faster data speeds over this medium. The various xDSL technologies are given below. • 1. ADSL (Asymmetric Digital Subscriber Line) • 2. VDSL (Very High-Speed Digital Subscriber Line) • 3. RADSL (Rate Adaptive Digital Subscriber Line) • 4. HDSL (High Data-Rate Digital Subscriber Line) • 5. SDSL (Symmetric Digital Subscriber Line

  6. 1. ADSL (Asymmetric Digital Subscriber Line) • It is a form of DSL, that enables faster data transmission over copper telephone lines than a conventional modem can provide.ADSLhas the distinguishing characteristic that the data can flow faster in one direction (used for download streaming) . • 2.VDSL (Very-High-Speed DSL) • Very-high-speed DSL (VDSL) promises even higher speeds than ADSL, although over much shorter distances. Originally named VADSL (A –Asymmetric) but was later extended to support both symmetric & asymmetric. Requires one phone line and supports voice & data. It works between 0.3-1.37 kms depending on speed. It supports upstream data rate of 1.6-2.3 mbps & downstream data rate of 13-52 mbps. • 3. RADSL(Rate-Adaptive DSL) • As the name implies, rate-adaptive DSL (RADSL) modems adjust the data rate to match the quality of the twisted-pair connection. Emerging software should make this an automated process with little human intervention.  

  7. 4.HDSL(High-Data-Rate DSL) • HDSL modem is viewed as equivalent of PCM stream(2 Mbps) and offers the same bandwidth both upstream and downstream. It can work up to a distance of 3.66 to 4.57 kms depending upon the speed required. It can deliver 2048 kbps • 5. SDSL(Symmetric DSL) • Symmetrical digital subscriber line (SDSL) is similar to HDSL but requires only one pair of wires. Transmission speed ranges from n x 64 kbps to 2.0 Mbps in both directions. In this the upload and download streams are of equivalent bandwidth. 2  CABLE MODEM • The cable network was primarily designed to deliver TV signals in one direction from the Head-End to the subscriber’s homes. Operators had to upgrade the cable network so that signals could flow bi-directionally. One spectrum is used for the signals that move from the Head-End towards the cable subscriber. Another spectrum of signal frequencies is used for the signals that move from the cable subscriber .In the downstream direction (from the network to the computer), network speeds can be up to 27 Mbps. In the upstream direction (from computer to network), speeds can be up to 10 Mbps. Most modem producers have selected a more optimum speed between 500 Kbps and 2.5 Mbps.

  8. 3. POWER LINE COMMUNICATION (PLC) • PLC also called Broadband over Power Lines (BPL) or Power Line Telecoms (PLT), is a wireline technology that is able to use the current electricity networks for data and voice transmission. PLC modems transmit in medium and high frequency (1.6 to 30 MHz electric carrier). The asymmetric speed in the modem is generally from 256 kbit/s to 2.7 Mbit/s. • ADVANTAGES • The major advantage of BPL over regular cable or DSL connections is the availability of the extensive infrastructure already available which would appear to allow more people in more locations to have access to the Internet.

  9. WIRELESS MODEM 1.WI-FI( WIRELESS FIDELITY)   Wi-Fi is an abbreviation for "wireless fidelity” .Wi-Fi was intended to allow mobile devices, such as laptop computers and personal digital assistants (PDAs) to connect to local area networks, but is now often used for wireless Internet access. A Wi-Fi-enabled device is able to connect to a local area network when near one of the network's access points . If the local area network is connected to the Internet, the Wi-Fi device can have Internet access as well. The access point built into a typical Wi-Fi home router might have a range of 45 m (150 ft) indoors and 90 m (300 ft) outdoors. Advantages of Wi-Fi • Allows LANs to be deployed without cabling, potentially reducing the costs of network deployment and expansion. Spaces where cables cannot be run, such as outdoor areas and historical buildings, can host wireless LANs. • Competition amongst vendors has lowered prices considerably since their inception. • Many Wi-Fi roaming, in which a mobile client station such as a laptop computer can move from one access point to another as the user moves around a building or area. • Many access points and network interfaces support various degrees of encryption to protect traffic from interception.

  10. 2.WIMAX  WiMAX is an acronym that stands for Worldwide Interoperability for Microwave Access.WiMAX cover wider, metropolitan or rural areas. It can provide data rates up to 75 megabits per second (Mbps) per base station with typical cell sizes of 2 to 10 kilometers. This is enough bandwidth to simultaneously support (through a single base station) more than 60 businesses with T1/E1-type connectivity and hundreds of homes with DSL-type connectivity. It is similar to Wi-Fi in concept, but has certain improvements done at improving performance and should permit usage over much great distances. It will provide fixed, portable, and eventually mobile wireless broadband connectivity and also provides POTS services. 3.Free Space Optics  FSO is optical, wireless, point-to-point, line-of-sight broadband technology that is an alternative to fiber optic cable systems without expense of fiber. Speed is comparable to fiber optic transmissions and transmits up to 1.25 Gbps at distance of 4 miles (6.4 kilometers) in full-duplex mode. • Advantages of FSO Significantly less expensive than fiber optic or leased lines Much faster installation, days or weeks compared to months for fiber optic cables Security is key advantage; not easy to intercept or decode  • Disadvantage of FSO Loss of Signal due to Fog Interference of signal due to bird/flies obstructing the signal .
