Bluetooth
is an industrial specification for wireless personal area networks (PANs), also
known as IEEE 802.15.1. Bluetooth provides a way to connect and exchange information
between devices like personal digital assistants (PDAs), mobile phones, laptops,
PCs, printers, digital cameras and video game consoles via a secure, globally
unlicensed short-range radio frequency. Bluetooth is a radio standard and communications
protocol primarily designed for low power consumption, with a short range (power
class dependent: 1 meter, 10 meters, 100 meters) based around low-cost transceiver
microchips in each device.Wifi hotspots are very common now days. Laptops and
PDAs use these hotspots to access the internet as these devices have Wifi facility
built into it. But mobile phones do not have Wifi facility in them. Nokia is releasing
some models with Wifi, but still those models are costly. But lower end models
also come with Bluetooth now. So its a better idea to create a Bluetooth hotspot
where Bluetooth mobiles can access the internet.With this technology mobile phones
need not have a GPRS connection or even a SIM card in it to access the internet.
This project has two parts. A client application and a server application. The
server application runs in a normal PC with Bluetooth dongle. This PC acts as
the gateway to the internet for the mobile. The mobile will host the client application
which will connect to the server application in a hotspot environment and provide
the mobile with internet access. <<back |
