BT to increase number of Wi-Fi hotspots to 1 million
BT plans to increase the number of WiFi hotspots two – fold that it has in the UK to about 1 million within the next 6 months as it looks to tap into the increase in demand for mobile internet.
BT has already gone past the 500,000 number, which is a landmark which took BT nearly 7 years to get past. However, with the number of customers wanting to access fast internet from their mobile phones increasing, the telcos is seeking to increase the stakes when creating new WiFi networks.
The actual revolution is the mobile phone, according to the wireless broadband director of BT Retail, Dave Hughes. People are OK with using their mobile phones to update their status on social networks or to check their emails, which isn’t the actual case with laptops.
He added that while 3G networks will have proper coverage for most users, there is an increasing demand for high speed broadband.
BT expects the massive increase in the size of their coverage to speed up the usage of their network. The extremely profitable WiFi division of Vodafone has doubled their traffic by a minimum of two – fold every year, Hughes added, and he also said that the network has the potential to further grow.
BT has hotspots in a number of public places by way of the Openzone network as well as in 12 city centres like the Westminister part of London which have public WiFi networks installed. The company has recently got a contract provide WiFi hotspots in all Starbucks coffee shops despite the competition from T-Mobile, which had clinched the contract previously.
They also operate a community – based WiFi services by way of the FON network and it is this segment of their business that most of the growth is set to occur. WiFi is functioning as a very integral retention tool for customers for their BT broadband business as the access to Openzone networks is also part of bundled minutes. Casual WiFi users can access their networks for 15 pence per minute.

Wi-Fi
Surfing on the Road with Wi-Fi
Local wireless internet access has become synonymous with the term WiFi. If you want to go browsing online with your laptop, netbook or mobile handset suitably equipped with WiFi, you go to the mall or café that is said to be “hotspot.” That means it’s has a local area network with a broadband connection to any Internet Service provider and an access device that broadcasts a radio frequency spectrum allowed for WiFi operation.
If your mobile handset detects this, it can tune into it an get into a handshake protocol to initiate an internet session provided the access is not restricted. Otherwise, your handset or laptop will prompt your for a password.
Some people may have mistakenly understood WiFi to mean “Wireless fidelity” from the more familiar term HiFi which meant High Fidelity in stereo systems. It doesn’t really stand for any specific phrase. Wi-Fi is just a trademarked term to stand for the IEEE 802.11x. wireless networking standard.
A Technical Definition
WiFi has come to stand for the slew of wireless LAN standards defined by the WiFi Alliance, the organization that has the trademark rights to the term which is technical defined as any "wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers' (IEEE) 802.11 standards." In its early days, WiFi referred only to the 802.11b standard using 2.4Ghz spectrum.
But over the years, the WiFi Alliance has used the term as an umbrella for all WLAN products using any of the IEEE 802.11 telecommunications standard that includes 802.11a dual band all the way to its variants. These days, you see WLAN specification on mobile handsets with the WiFi 802.11 b/g specified on it. This particular Wi-Fi variant enjoys popular support from various mobile device makers.
They include video game consoles, PDAs and mobile phones as well as netbooks and laptops. Any gadget with the “WiFi Certified” label indicates it has passed the WiFi Alliance certification and can access any similarly certified WiFi access point. The certification indicates what frequency it can recognize, usually 2.5Ghz for 802.11b,g,n and 5Ghz for 802.11a.
