There are a number of reasons to have as fast a service as possible ranging from:Impressive, and not just the speed, but I wonder at what point the speed is superfluous?
At my less than 4 mbs, I search Google almost instantly, and watch now TV (WiFi) with no loss of service
Existing broadband is struggling to support the increasing number of Internet-capable devices in the home, which include but not restricted to mobile phones, iPads and tablets, notebooks, e-readers (such as Kindle), desktop PCs, games consoles, Apple TV and media players, Sky+ boxes.
Without superfast broadband, consumers miss out on some services a large (and rapidly increasing) number of bandwidth-intensive services use broadband as a delivery mechanism. BBC iPlayer requires at least 3Mbps to stream HD content, and Netflix can demand 6Mbps or more to stream high-quality video. Online backups of important content, such as family photographs, can be unbearably slow with conventional broadband. Without superfast broadband, consumers have an increasingly reduced set of onlineservices to choose from.
Superfast broadband could increase house prices, A survey carried out by ispreview.co.uk found that 68.8% of respondents would be put off from buying a “beautiful new house” if it lacked fast broadband. 73.9% considered that broadband was “critically important” to their home life.
Superfast broadband connectivity is essential for many businesses Superfast broadband is increasingly becoming essential to businesses, whatever the size of the business. In businesses with a significant number of employees, superfast broadband ensures that employees no longer have to compete for access to slow and limited conventional broadband services, increasing efficiency. Widespread deployment of superfast broadband services also allows businesses to provide flexible working for employees so that they can work from home and access company systems remotely, saving costs and reducing carbon footprints.
Conventional broadband services can be unreliable ADSL broadband is carried along copper cables all the way from the BT exchange to homes and business premises. Inevitably, the broadband signal suffers attenuation as it travels along the copper cable from the exchange to broadband modems, reducing the speeds that can be delivered and making the broadband signal susceptible to interference. In contrast, high-speed fiber broadband utilizes fiber-optic cables, which are immune to interference and do not suffer the signal attenuation experienced by copper lines. As a result, superfast broadband services deliver significantly higher speeds and are more reliable.
Fiber is Green starting to think that sending data via electricity over metal wires is wasteful? If so, then you would be correct; data sent over metal wires takes much more energy that it takes to send a light signal. The additional substations and nodes needed to keep that signal strong over greater distances only adds to the woes of metal wires. Add to this the fact that the cables virtually never go bad, and it is simple to see why fiber optics are considered a green alternative to metal wires and electricity in any form.
