Hello All,
This is an idea for those who are into embedded linux systems. The
concept is to create wireless internet access in taxis, cars and buses.
The options available today are the wireless data cards or mobile phones
or FWP phones attached to individual laptops. But what happens when more
passengers want to access the net and everyone may not have a data card.
So we need a black box that acts as an interface with the phone's ( net
service provided by the transporter) usb cable and the network interface
of a Wireless AP.
I don't know if any ready made phone is available with a direct network
interface and a built-in ppp dialer but the simple way out would be to
use an old pc or laptop as the interface and share that connection at
its ethernet port. However that would make it too bulky and power consuming.
The other approach would be to have something like the ADSL modem that
is a network interface and a pppoe dialer bundled together. In our black
box we need a usb interface that can detect different wireless phones, a
pppoe dialer to make a connection and a network interface to connect to
the W AP. Everytime the connection breaks, it will automatically redial.
The cost of a dialup session for RIL internet is 50p/minute so Rs. 30
for an hour. That amount can be divided among the passengers and they
benefit by being online without a data card. Local buses and taxis can
use FWP phones and long distance luxury buses, taxis will use mobile
phones as the network device. For buses, more phones and devices with W
APs can be added as per demand, for better bandwidth.
Everyday, the gaps between no signal areas is closing in and we will get
almost seamless net access across the travel region.
Regards,
Rony.
