| Username and password BSNL will activate the Broadband Service by allotting Username and password. The Password given by BSNL need be used for the first time login and thereafter Customer may change and customize his/her Password. Telephone Line Splitter Broadband modem USB or LAN Connection Telephone Instrument How to Change Password Change of Password for your username is a two steps process. 1. Change the password for your account at our Self Care Website http://www.dataone.in or http:// bbservice.bsnl.in 2. Then change the password in your Modem. For assistance contact the JTO/SDE or NIB. How to check the usage Please visit the Website http://www.dataone.in or http://bbservice.bsnl.in/ for checking the usage details. What can be done with 1 GB One GB is 1024 Megabyte or 1073741824 bytes. You can do the following with 1 GB download limit : 1. An average web page is about 50 kilobytes in size - so you could download around 20,000 web pages for 1 gigabyte. 2. An hour of surfing the web would be around 10 megabytes (200 pages) so you could surf nonstop for about 100 hours for 1 gigabyte. 3. An hour of streamed radio would use about 15-20 megabytes. 4. An hour of streamed video uses around 100-150 megabytes. 5. Playing an online game typically uses about 10-15 megabytes per hour. 6. A super-high resolution (5-6 megapixel) digital camera JPEG picture or typical MP music file is about 2-3 megabytes so you could download 350-500 of these images/music files for 1 gigabyte. 7. Emails are very small - so 100 emails would be just 1 megabyte - or 100,000 emails for 1 gigabyte (of course the attachments count extra) BROADBAND THROUGH WIFI AND WIMAX Any two computers can be directly wired to each other using a crossover cable. When number of computer exceeds, cables must be run from each computer to another computer or to the central device. It can be time-consuming and difficult to run cables under the floor or through walls, especially when computers sit indifferent rooms. The correct cabling configuration fora wired LAN varies depending on the mix of devices, the type of Internet connection, and whether internal or external modems are used. Look around us at the moment, we have our keyboard connected to the computer, as well as a printer, mouse, monitor and soon. What (literally) joins all of these together, they are connected by cables. Cables have become the bane of many offices. Most of us have experienced the 'joys' of trying to figure out what cable goes where, and getting tangled up in the details. Is there a technology to replace cable Wireless is the answer. Today WLAN technologies all follow one of the three main WiFi communication standards. The benefits of wireless networking depend on the standard employed b was the first standard to be widely used in WLANs. Thea standard is faster but more expensive than b a is more commonly found in business networks. The newest standard, g, attempts to combine the best of both a and b, though it too is more a more expensive home networking option. WiFi networks can be configured in two different ways 1. "Ad hoc" mode allows wireless devices to communicate in peer-to-peer mode with each other. 2. "Infrastructure" mode allows wireless devices to communicate with a central node that in turn can communicate with wired nodes on that LAN. Most LANs require infrastructure mode to access the Internet, a local printer, or other wired services, whereas ad hoc mode supports only basic file sharing between wireless devices. A BSS that stands alone and is not connected to abase is called an Independent Basic Service Set (IBSS) or is referred to as an Ad-Hoc Network. An ad-hoc network is a network where stations communicate only peer to peer. Ad-Hoc or IBSS networks are characteristically limited both temporally and spatially. Creating large and complex networks using BSS's and DS's leads us to the next level of hierarchy, the Extended Service Set or ESS. The beauty of the ESS is the entire network looks like an independent basic service set to the Logical Link Control layer (LLC). This means that stations within the ESS can communicate or even move between BSS_s transparently to the LLC. The main problem with WiFi access is that hot spots are very small, so coverage is sparse. Is there anew technology that would provide high speed of broadband service, Wireless rather than wired access, so it would be a lot less expensive than cable or DSL and much easier to extend to suburban and rural areas and Broad coverage like the cellphone network instead of the tiny little hotspots of WiFi. This technology is called WiMAX, short for Worldwide Interoperability for Microwave Access. The big difference between WiFi and WiMAX is that we're going to use licensed spectrum to deliver WiMAX. To date, all WiFi technology has been delivered in unlicensed spectrum. WiMAX will use one of the unlicensed frequencies, but we're also supporting two other frequencies that are licensed. What that means is that you can turn up the output power and broadcast longer distances. So where WiFi is something that is measured in hundreds of feet, usually WiMAX will have a very good value proposition and bandwidth up to several miles. services, providing universal Internet access just about anywhere you go. WiMAX will also be as painless as WiFi -- turning your computer on will automatically connect you to the closest available WiMAX antenna. A WiMAX system consists of two parts 1. Ab WiMAX tower, similar in concept to a cellphone tower - A single WiMAX tower can provide coverage to a very large area -- as big as 3,000 square miles ( 8,000 square km. 2. Ab WiMAX receiver - The receiver and antenna could be a small box or PCMCIA card, or they could be built into a laptop the way WiFi access is today. A WiMAX tower station can connect directly to the Internet using a high-bandwidth, wired connection (for example, a T line. It can also connect to another WiMAX tower using a lineof- sight, microwave link. This connection to a second tower (often referred to as ab backhaulb), along with the ability of a single tower to cover up to 3,000 square miles, is what allows WiMAX to provide coverage to remote rural areas. What this points out is that WiMAX actually can provide two forms of wireless service • There is the non-line-of-sight, WiFi sort of service, where a small antenna on your computer connects to the tower. In this mode, WiMAX uses a lower frequency range -- 2 GHz to 11 GHz (similar to WiFi. Lower-wavelength transmissions are not as easily disrupted by physical obstructions -- they are better able to diffract, or bend, around obstacles. • There is line-of-sight service, where a fixed dish antenna points straight at the WiMAX tower from a rooftop or pole. The line-of-sight connection is stronger and more stable, so it's able to send a lot of data with fewer errors. Line-of-sight Download 1.04 Mb. Share with your friends:
