Definition of Broadband Internet: Broadband is a faster way for you to gain access to the Internet and the sites or pages that a man wants to see. Broadband Internet offers high-speed Internet access - high speed in terms of data transmission, upload, and download times, and connectivity. If you compare broadband Internet with a regular dial-up connection, you certainly won’t like going back to the latter.

HISTORY:

In the late 1960s, researchers in the US gained funding from the Defense Advanced Research Projects Agency (DARPA) to begin development of the first network of computer systems. The first such connection was established on the 29th of November 1969. The network was referred to as ARPANET. The first true network of computers, named ARPANET, was formed in 1969 after funding from the Defense Advanced Research Projects Agency. It originally existed as a connection between the University of Los Angeles, California and the Stanford Research Institute. Shortly afterwards it was expanded by adding nodes at the University of Utah and the University of Santa Barbara, California and has continued to grow. Throughout the 1970s some Australians made periodic connections to the network via a dial-up service. This was Australia's first contact with the Internet.

In 1987-1988 a report was drafted for the Australian Vice Chancellor's Committee, requesting that it fund development of a local data, voice and fax network. After initial planning and research was done the position of Technical Manager of the network was created. It was filled by Geoff Huston. After much research throughout the late 80s, Geoff Huston was transferred from his post at the Australian National University to the AVCC to oversee the creation of a local data network. He worked with people such as Robert Elz, Ken McKinnon and Robin Erskine planning the logistics of the operation.

On the 23rd of June 1989 Australia's first proper Internet connection went live from Robert Elz's lab at the University of Melbourne. The AVCC had overseen the installation of a 56Kbps satellite network which formed the basis for this system. To do so it worked in tandem with NASA and the University of Hawaii.The basis for the network was a satellite system developed jointly by the AVCC and the University of Hawaii/NASA. It linked two land-based points in Australia and Hawaii and while it began as a 56Kbps network it was later upgraded to 128Kbps. The connection went live from Robert Elzs lab at the University of Melbourne on the 23rd of June 1989, marking the date as the birth of the Internet in Australia.

As 1989 progressed, more nodes were added to the network. A 48Kbps connection to ANU was established in August, followed by a 9.6Kbps link with the University of Sydney and a 48Kbps link with the University of Adelaide in October. This network was referred to as AARNet. AARNet was the first effort to establish a local, Internet capable network of computers within Australia and formed the basic infrastructure that eventually turned into the Internet as we know it.

AARNet was a network supporting Data In an effort to make it as fast as possible the decision was made that AARNet would be exclusively a data service, with no support for voice or fax.

It is arguable who the first real ISP in Australia was; however, it is known that as early as June 1989, very near to the date when the AARNet network went live, a Byron Bay-based company began offering UUCP and TCP/IP based connections. This company was called Pegasus Networks.

It is difficult to ascertain exactly who the first ISP in Australia was. One company, DIALix, claims it has offered commercial Internet connectivity as early as 1989; however, it wasn't fully IP-based until several years later. Pegasus Internet was founded at a similar time, providing full TCP/IP and UUCP connections to the Internet. It provided local access in June 1989 and moved to full national coverage in September 1989.

In 1994 AARNet added a new program, known as VAR (Value Added Reseller). Through this program they charged members a volume rate per megabyte of data transferred. The first ISP registered under this scheme was connect.com.au.Previously AARNet had operated on a levy-based system but with the increasing popularity of the Internet they knew they needed to shift to a new model. In 1994 they introduced a volume-based system known as Value Added Reseller (VAR), where members would be charged based on the data used rather than as a flat fee. Connect.com.au was the first company to register under the new system, making them the first real ISP in many people's eyes.

Due to increasing demand, by the end of 1994 it became obvious to AARNet that a new business model was needed. Thus in 1995 it sold off its assets, customers and infrastructure. The new company responsible for the Internet within Australia was TelstraStruggling with increased demand filtering in through ISPs, AARNet decided it needed to make some changes. Thus in 1995 it transferred its entire infrastructure, including clients, networks and hardware across to Telstra, effectively handing them control of the Internet infrastructure in Australia.

On the 28th of May 1996, OzEmail became the first technology stock – in Australian history – to be listed on the NASDAQ (listed under the symbol OZMEY). By doing this the company roughly raised $50 million. OzEmail became the first technology stock listed on the NASDAQ on the 28th of May 1996. They raised $AUD50 million in investment capital and two years later they listed on the Australian stock exchange under the symbol OZM.

In 1999 Telstra rolled out its first ADSL service in Australia which was subsequently utilised and sold by other ISPs. The maximum speeds of this new network at the time were 1500/256Kbps. When it was first rolled out, ADSL in Australia was capped at 1500/256Kbps despite being capable of faster speeds. Over time some ISPs began installing their own DSLAM equipment in Telstra's exchanges which enabled them to achieve speeds faster than the Telstra cap.

In February 2004 Telstra announced that it was offering a new entry-level ADSL package designed to help low volume users make the jump from dial-up. The plan offered 200MB for $29.95 a month. Telstra's introduction of a low cost, widely accessible broadband plan in February 2004 was one of the key catalysts for Internet growth in Australia. At $29.95 a month it was as affordable as many dial-up plans at the time, although 200MB is a fairly paltry offering by modern standards.

On February 28th 2005 OzEmail was officially taken over by one of its competitors. That company was iiNet. On the 28th of February 2005 iiNet completed its takeover of OzEmail. Absorbing what was once one of the tier one Australian ISPs was a big boost for the company, bumping them up to the third largest ISP in Australia and the second largest provider of broadband.

Offering a theoretical maximum of up to 24Mbps, ADSL2+ was the next logical step for Australian broadband. In 2005 the first such plan became available to consumers through the ISP Internode. ADSL2+ is still the benchmark for broadband in Australia even today. It was rolled out in 2005 with Internode offering the first plans. With a theoretical maximum download rate of 24Mbps it allows for extremely fast downloads depending on your proximity to the node.

DSL, or Digital Subscriber Line, uses the available bandwidth in your phone line to deliver additional signals. A typical pair of copper wires in your phone is capable of carrying information on many different frequencies.

The broadband technology you choose will depend on a number of factors. These may include whether you are located in an urban or rural area, how broadband Internet access is packaged with other services (like voice telephone and home entertainment), price, and availability.

Digital Subscriber Line (DSL)

DSL is a wireline transmission technology that transmits data faster over traditional copper telephone lines already installed to homes and businesses. DSL-based broadband provides transmission speeds ranging from several hundred Kbps to millions of bits per second (Mbps). The availability and speed of your DSL service may depend on the distance from your home or business to the closest telephone company facility.

The following are types of DSL transmission technologies:

Asymmetrical Digital Subscriber Line (ADSL) – used primarily by residential customer

e following are types of DSL transmission technologies:

Asymmetrical Digital Subscriber Line (ADSL) – used primarily by residential customers, such as Internet surfers, who receive a lot of data but do not send much. ADSL typically provides faster speed in the downstream direction than the upstream direction. ADSL allows faster downstream data transmission over the same line used to provide voice service, without disrupting regular telephone calls on that line.

Symmetrical Digital Subscriber Line (SDSL) – used typically by businesses for services such as video conferencing, which need significant bandwidth both upstream and downstream.

Faster forms of DSL typically available to businesses include:

High-data-rate Digital Subscriber Line (HDSL); and Very High-data-rate Digital Subscriber Line (VDSL).

Cable Modem

Cable modem service enables cable operators to provide broadband using the same coaxial cables that deliver pictures and sound to your TV set.

Most cable modems are

Cable modem service enables cable operators to provide broadband using the same coaxial cables that deliver pictures and sound to your TV set.

Most cable modems are external devices that have two connections, one to the cable wall outlet and the other to a computer. They provide transmission speeds of 1.5 Mbps or more.

Subscribers can access their cable modem service simply by turning on their computers without dialing-up an ISP. You can still watch cable TV while using it. Transmission speeds vary depending on the type of cable modem, cable network, and traffic load. Speeds are comparable to DSL.

Fiber

Fiber, or fiber optic, is a newer technology available for providing broadband. Fiber optic technology converts electrical signals carrying data to light and sends the light through transparent glass fibers about the diameter of a human hair. Fiber transmits data at speeds far exceeding current DSL or cable modem speeds, typically by tens or even hundreds of Mbps.

The actual speed you experience will vary depending upon a variety of factors, such as how close to your computer the service provider brings the fiber, and how the service provider configures the service, including the amount of bandwidth

used. The same fiber providing your broadband can also simultaneously deliver voice (VoIP) and video services, including video-on-demand.

Telecommunications providers (mostly telephone companies) are offering fiber broadband in limited areas and have announced plans to

nd connects a home or business to the Internet using a radio link between the customer’s location and the service provider’s facility. Wireless broadband can be mobile or fixed.

Wireless technologies using longer range directional equipment provide broadband service in remote or sparsely populated areas where DSL or cable modem service would be costly to provide. Speeds are generally comparable to DSL and cable modem. An external antenna is usually required.

Fixed wireless broadband service is becoming more and more widely available at airports, city parks, bookstores, and other public locations called “hotspots.” Hotspots generally use a short-range technology that provides speeds up to 54 Mbps. Wireless fidelity (Wi-Fi) technology is also often used in conjunction with DSL or cable modem service to connect devices within a home or business to the Internet via a broadband connection.

Mobile wireless broadband services are also becoming available from mobile telephone service providers and others. These services are generally appropriate for highly-mobile customers and require a special PC card with a built in antenna that plugs into a user’s laptop computer. Generally, they provide lower speeds, in the range of several hundred Kbps.

Satellite

Just as satellites orbiting the earth providJust as satellites orbiting the earth provide necessary links for telephone and television service, they can also provide links for broadband. Satellite broadband is another form of wireless broadband, also useful for serving remote or sparsely populated areas.

Downstream and upstream speeds for satellite broadband depend on several factors, including the provider and service package purchased, the consumer’s line of sight to the orbiting satellite, and the weather. Typically a consumer can expect to receive (download) at a speed of about 500 Kbps and send (upload) at a speed of about 80 Kbps. These speeds may be slower than DSL and cable modem, but download speed is about 10 times faster than download speed with dial-up Internet access. Service can be disrupted in extreme weather conditions.

Definition of Wimax Internet: WiMAX can be used for wireless networking in much the same way as the more common WiFi protocol.  WiMAX is a second-generation protocol that allows for more efficient bandwidth use, interference avoidance, and is intended to allow higher data rates over longer distances. The IEEE 802.16 standard defines the technical features of the communications protocol.  The WiMAX Forum offers a means of testing manufacturer's equipment for compatibility, as well as an industry group dedicated to fostering the development and commercialization of the technology WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless "metropolitan area networks".   WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 - 10 miles (5 - 15 km) for mobile stations.  In contrast, the WiFi/802.11 wireless local area network standard is limited providing a regulated environment and viable economic model for wireless carriers.in most cases to only 100 - 300 feet (30 - 100m).With WiMAX, WiFi-like data rates are easily supported, but the issue of interference is lessened.   WiMAX operates on both licensed and non-licensed frequencies, WiMax.com provides a focal point for consumers, service providers, manufacturers, analysts, and researchers who are interested in WiMAX technology, services, and products.  Soon, WiMAX will be a very well recognized term to describe wireless Internet access throughout the world.

history

Worldwide Interoperability for Microwave Access (WiMAX) is a technology that provides mobile broadband Internet access anywhere, anytime in a cost effective manner. The objective of this tutorial is to provide an in-depth technical knowledge about WiMAX technology as well as information about its current standardization and deployment status. The tutorial is intended for those who want to learn the technical details of WiMAX and explore the research challenges as well as to the professionals who are interested in understanding the technical and the market aspects. The tutorial’s objective is making the audience knowledgeable about the salient features of WiMAX technology, WiMAX standardization as well as WiMAX industry forces that are driving the technology. The tutorial is divided into the following sections: introduction to WiMAX, WiMAX air interface, WiMAX core

network architecture, WiMAX system performance, present status of WiMAX deployments as well as the future of WiMAX.

The introduction covers the history of WiMAX, the standardization of WiMAX technology and overview of its key differentiating features that enable mobile broadband Internet. Following the introduction, the air interface section of tutorial covers the technical details of the PHY and MAC layers of WiMAX technology standardized by the IEEE 802.16 family of specifications. The PHY layer includes the advanced features of WiMAX air interface, such as scalable OFDMA based channel access, adaptive antenna systems (AAS) (such as MIMO, beam forming), and advanced coding and modulation. The MAC includes QoS support, security, support for reliable data transfer, enhanced mobility support as well as improved power saving mechanisms. The WiMAX core network architecture section describes the end-to-end IP-based network architecture for WiMAX standardized by the Network Working Group (NWG) of WiMAX Forum. Following the description of WiMAX specifications, the tutorial looks at the system performance aspects of mobile WiMAX . The tutorial concludes with the current status of WiMAX deployments as well as its future trends.

Advantages :

1) Single station can serve hundreds of users.

2) Much faster deployment of new users comparing to wired networks.

3) Speed of 10 Mbps at 10 kilometers with line-of-site.

4) It is standardized, and same frequency equipment should work together.

Disadvantages :

1) Line of site is needed for longer connections

2) Weather conditions like rain could interrupt the signal.

3) 0ther wireless equipment could cause interference.

4) Multiplied frequencies are used.

5) WiMAX is very power intensive technology and requires strong electrical support.

6) Big installation and operational coast.

Costing of Wimax Internet:

The most obvious conclusion when comparing the cost of different service profiles for WiMAX is that the technology is not well suited for high transmission rates. The cost of SP4 is 400% more expensive than SP1. Despite this, WiMAX provides an inexpensive solution to low speed transmission rates where other infrastructure is missing. Our providing internet connectivity. The mild increase in cost for rural areas indicates a clear window analysis highlights the competitive nature of WiMAX as a short time solution for of opportunity for the technology. The drawback of WiMAX is the temporary nature due to expensive transmission pr. bit and thus high upgrade costs for increased throughput.Today, we are using connection methods that were made popular over the past several years.A newer standard called: "WiMax" now exists. Some of the reported advantages toWiMax include lower cost, higher speeds, longer distances covered and easier deployment.My wireless Internet idea uses this newer standard. Computer makers like Intel willinclude them in next year's models (we will need to buy equipment for our existingcomputers - see subscriber unit discussed below). A savings of $51 ($345-$396 Comcast) or $225 ($345-$600 AT&T) the first year and $276($396-$120 Comcast) or $480 ($600-$120 AT&T) the second year. A citywide blanket coverage of wireless Internet access sounds great, but companies aren't going to go around setting up WiMAX base stations out of sheer kindness. Who's going to pay for WiMAX? It depends how it will be used. There are two ways WiMAX can be implemented -- as a zone for wireless connections that single users go to when they want to connect to the Internet on a laptop (the non-line-of-sight "super WiFi" implementation), or as a line-of-sight hub used to connect hundreds of customers to a steady, always-on, high-speed wireless Internet connection. Under the "super WiFi" plan, cities might pay to have WiMAX base stations set up in key areas for business and commerce and then allow people to use them for free. They already do this with WiFi, but instead of putting in a bunch of WiFi hot spots that cover a few hundred square yards, a city could pay for one WiMAX base station and cover an entire financial district. This could provide a strong draw when city leaders try to attract businesses to their area. Some companies might set up WiMAX transmitters and then make people pay for access. Again, this is similar to strategies used for WiFi, but a much wider area would be covered. Instead of hopping from one hot spot to another, WiMAX-enabled users could have Internet access anywhere within 30 miles of the WiMAX base station. These companies might offer unlimited access for a monthly fee or a "pay as you go" plan that charges on a per-minute or per-hour basis.
