Wi-Fi Direct – Is this the end of Bluetooth?
Wi-Fi Alliance (this includes companies like apple and Nokia) has decided to launch a Bluetooth rival that’s going to do the work of Bluetooth in a better way. It’s named Wi-Fi Direct. This allows laptops and smart phones to form peer to peer connection without the need of them to connect to a network. The most exciting thing about Wi-Fi Direct is its backward compatibility. This can be implemented in older Wi-Fi devices through a firmware patch.
It’s expected to offer a speed of almost 10 times that of Bluetooth, i.e., it would offer 250 Mbits per second. It would work in greater distance than that of Bluetooth.
Know About Wi-Fi Routers
When you get into a store to buy a Wi-Fi router ,you would come across the terms Single-band ,Dual band, N and G. What are these actually?.These are the key terms of the routers and decides your selection good or bad. Almost every current broadband router comes with a Wi-Fi capability. Never go behind a Wi-Fi router by the advertisers claims. Some claim a 300 Mbps speed that’s of no use in the current world. You will never find a hot spot with such a speed. Never look for the speeds, instead look for the features.
The N and G are actually the IEEE standards. N for 802.11n and G for 802.11g . G routers are always cheaper than N and its been used for the past 7 yrs and still stays in the market because of its threat management and powerful firewall features. When you go for only speed, N routers rocks.
N routers are classified into 2 types - Single Band (2.4GHz) and Dual Band (2.4GHz and 5 GHz). Even a single-band N routers are faster than G routers due to the better use of frequency. Dual band routers are much expensive but its worth paying with its whooping speeds than that of a single band.
