BROADBAND INTERNETINFRASTRUCTUREBy Tebra Righeibi
TYPES OF TELECOMMUNICATIONSFixed WiredDSL: Digital Suscriber Lineis a technology for bringing high bandwidth* information to homes and smallbusinesses over ordinary copper telephone linesHow it works;• Traditional phone service was created for voice exchange and this type of transmission is an analogue signal.• As telephone companies already have this analogue wave transmission set up, it was easier to use this method to transmit information this way.• That is why a modem is needed to demodulate** the analogue signal and turn it into digital informationWhat it does:• Transmits digital data over the wires of a local telephone network• Uses copper wiring in conjunction with other hardware• Unlike dialup internet access, telephone can be used at the same time as using the internet• Download speeds of at least 256 kbit/s• Requires an active landline and usually line rental*Bandwidth: Data transfer rate**Demodulate: To extract information from a modulated signal
TYPES OF TELECOMMUNICATIONSFixed WiredCable:A cable modem is a device that enables you to hook up your PC to alocal cable TV lineHow it works:• Modulates between analogue and digital signal• Can be an external device or integrated within a computer or set top box• Usually the cable modem attaches to an Ethernet* card in the computerWhat it does:• All of the cable modems attached to a cable TV company’s coaxial cable line communicate with a Cable Modem Termination System (CMTS) at the local cable TV company office.• Cable modems can receive from and send signals only to the CMTS, but not to other cable modems on the line• Download speeds greater than 256 kbit/s*Ethernet: the most widely-installed local area network ( LAN) technology. AnEthernet LAN typically uses coaxial cable or special grades of twistedpair wires.
TYPES OF TELECOMMUNICATIONSFixed WiredFibre Power Broadband:How it works:• Connection is established through the use of a cable modem• TV channel space is used for transferring data upstream and downstream• Coaxial cable is used so that a greater bandwidth is achieved compared to DSL connections that require copper wiring for telephone linesFibre to the home – The Fibre cable is piped into your house directly.Fibre to the cabinet – Fibre cable will be built from the telephone exchangeto neighbourhood telecoms cabinets - midway between the exchange andthe home. In this case copper wiring carries the rest of the signal to thehome. By rolling out fibre closer to the home and reducing the length of thecopper line broadband download speeds are improved
TYPES OF TELECOMMUNICATIONSWirelessSatellite:two-way Internet access via satellitesHow it works:• The computer, through a special satellite modem, broadcasts requests to a satellite dish that is placed on the roof of a home/business• This dish then sends and receives signals from satellites in spaceWhat it does:• The Internet feed is beamed from satellite to a dish installed at the subscribers home• Not every home can have DSL or Cable broadband so satellite can be an alternative• Download speeds of at least 256 kbit/s
TYPES OF TELECOMMUNICATIONSWirelessTerrestrial fixed wireless:is to enable data communications between the two sites or buildings.How it works:• The point-to-point signal transmissions occur through the air over a terrestrial microwave platform rather than through copper or optical fibre• Fixed wireless does not require satellite feeds or local telephone service.• The ability to connect with users in remote areas without the need for laying new cables and the capacity for broad bandwidth that is not impeded by fibre or cable capacities.• Fixed wireless data (FWD) links are often a cost-effective alternative to leasing fibre or installing cables between the buildings.
TYPES OF TELECOMMUNICATIONSWirelessTerrestrial Mobile Wireless:Mobile broadband is internet access without the need for a fixed landline, allowing you to connect wirelessly to the internet wherever you areHow it works:• Uses the same technology as a mobile phone, except instead of making a voice call over the phone, the modem makes a data call across the mobile network which connects to the internet

BEST PACKAGE AVAILABLE TO ME UPC FIBRE POWER BROADBAND Package: Fibre Power Ultimate 79e a month (includes Digital TV and 100MB broadband) or Fibre Power Broadband 100MB 49e a month (Broadband only) For a SOHO scenario, the UPC Fibre Power Broadband package also applies as WiFi is available and with strong download speeds, several computers/internet devices can be used at the same time. For a Mobile Business scenario, the Vodafone Mobile WiFi device (29.99 a month) would be very useful as it will wirelessly connect to the Vodafone mobile broadband network most places in Ireland. Also up to five devices can be connected to the internet at on time, once they are WiFi enabled
