Wi-Fi phones
Connectivity is a major concern when it comes to embedded devices like the mobile phones. The standard methods of connections we use are USB, infra red, and bluetooth. But recently, with the development of Wi-Fi, mobile phone manufacturers are able to embed a Wi-Fi module in a phone.
These phones are very useful. There are a lot of Wi-Fi hot spots around us where you can just catchup with the network and use the facilities like internet for free.
Recently, I had been Changi airport, Singapore. They offer a free Wi-Fi service and almost all airports in the US provide free Wi-Fi service. I logged on, and surfed the internet for a good long period.
