Broadband Research.

1. What is   broadband?Of or using signals over a wide range of frequencies in high-capacity telecommunications, esp. as used for access to the Internet.
2. Outline the methods of delivery of broadband (wireless, cable, ADSL and fibre)? Identify the speed of each method.ADSL - ADSL is a digital connection to the internet that can run up to 30 times faster than a standard modem.
   Wireless - WLANs offer maximum theoretical bandwidth of 11 Mbps. 802.11a and 802.11g WLANs offer theoretical bandwidth up to 54 Mbps. (In contrast, typical wired Ethernets run at 100 Mbps.)
   Cable - Cable modem speeds vary widely. While cable modem technology can theoretically support up to about 30 Mbps, most providers offer service with between 1 Mbps and 6 Mbps bandwidth for downloads, and bandwidth between 128 Kbps and 768 Kbps for uploads.
   Fibre -
3. Discuss the advantages and disadvantages of each method.
   ADSL:Advantages:
   - Uninterrupted connection
   - Simulataneous data and voice transmission
   - faster speeds over ISDN and dial-up
   - Faster speeds, cheaper costsDisadvantages:
   - DSL efficiency is related to distance. The farther you are away from the provider, the more unreliable the service becomes.
   - People who need to upload large amounts of data such as corporate database, video, large audio files and images will not find DSL attractive though it is fast.
   - There is no standardization. Each company comes with its own equipment. So if you leave one city to go to the other, you may have to purchase a new set of equipment from the new company.
4. Give examples of broadband providers and identify the cost.
   Optus:Naked broadband plans -
   Cost: $79.99 per month = standard modem + Up to 500GB
   Up to 500GB naked broadband250GB peak + 250GB off peak
   Speed limited for both peak and off peak to 128kbps once peak or total data exceeded.
   Standard modem included, or upgrade to a WiFi modem $120.
   Telstra Big Pond:
   Big Pong Elite 200GB Liberty
   Usage allowance:  200GB (slower than 256kbps)
   Plan Term: 24 months
   Cost: from $69.95
   iiNet:
   ADSL2+ Home - 1
   Peak + Off peak: 100GB + 100GB
   Plan Speed: ADSL2+ Speeds
   Plan Price: $49.95
5. The Federal Government is thinking of rolling out a national broadband network. Research teh NBN and find out.
   a. What method of delivery it will use? The network would use fibre to the premises (FTTP), fixed wireless and satellite technologies to provide connections. This will be the first time, in Australia that retail service providers are going to be able to access infrastructure that is not owned or operated by a competitors.
   b. The expected speed? Up to gigabyte per second.
   c. The expected costs? The expected costs would include investing $43 billion on the NBN plan. Although the NBN co corporate plan confirmed that the total capital expenditure for the project would be estimated only $35.9 billion. Which is less than the originality thought. It is believe that most of this money will be from tax payers.
