Re: [cr-india] Cellphone-based community radio
Cool! Actually, just a clarification from my end. When I mentioned about our work with Asterisk, I was talking about the server side, of how the radio station could receive phone calls, archive the calls, put the caller on air, etc. Andrea and Gora are talking about the client side, of how radio content can be streamed over the Internet and then received on a cellphone. Just wanted to clear that to avoid confusion! On a related note, GRINS currently does not support Internet streaming, but this feature is very much in the pipeline. Andrea Tazzari wrote: Hi Gora, Thanks for your observation. I have circulate your message in our developer's team. Actually the sound quality it's more close to a AM broadcast than a FM this because we are streaming in mono and in very low bandwith (1Kbs/sec circa) in order to keep up the connection. With this speed the connection it's very stable and I have very few interruptions even when I'm travel with a bike or in car. I've tested all around Auroville, Pondicherry and Chennai and I'm very happy with the results. I have a connection @ 199 Rs/monts (unlimited traffic) with BSNL. Soon I'll increase the band-with in order to test with a better sound quality. Regards.

I have been talking to a friend of mine who runs an Internet radio music station about building a mobile application for the site. With PhoneGap, such an application can be used across a large number of handsets. Music will obviously require a connection with larger bandwidth than GPRS, but the front-end application can be the same, and moreover, the interface can easily be restyled with CSS. Would be glad to take a shot at building such an application. Due to commitments at work, it would be difficult for me to commit right now to a fixed time line. Nevertheless, let me know if this sounds interesting. [...] I have a connection @ 199 Rs/monts (unlimited traffic) with BSNL.

I really do not think that music will work on a GPRS connection, but do you have any plans of trying? Another thought: If streaming speech over GPRS is working well, it ought to be possible to send similar audio back to the radio station. Thus, one could have a live radio chat, or something like citizen journalism. Regards, Gora Join the Community Radio Forum. For membership details, please go to www.crforum.in

The best phone to use is a Nokia 2323 classic which is also one of the cheapest phones in the indian market at about $65.

The great advantages of streaming radio over GPRS is that (1) it gets around the Kafka-in-Pandemonium world of radio regulation in India and (2) the signal goes a hell of a long way compared to FM radio. I am not sure, though, if there are any inherent advantages in using skype-over-mobile or similar applications in favour of normal voice calls for routine phone-ins or field reports.

I should note that I have no actual experience of trying streaming music over low-bandwidth networks. I was just going by the bandwidth requirements cited by friends doing Internet music radio.

Yes, telephony is what I was thinking about. The advantage here would be cost, as GPRS data should be cheaper than normal voice data. Your first point about streaming radio over GPRS is well taken, and that was also my first thought in the context of community radio. Regards, Gora Join the Community Radio Forum.

Re: [cr-india] Cellphone-based community radio
Hello, We have been able to get Bluetooth enabled cellphones working with Asterisk to make and receive phone calls, but the audio quality is not too good. A better option is to use GSM PCI cards or GSM gateways: http://www.voip-info.org/wiki/view/GSM . We haven't tested any of these solutions so far, but we don't expect any significant glitches since they are already being used by many people. Sending and receiving SMS messages can be done through Frontline SMS: http://www.frontlinesms.com/ . It works with a variety of phone models and GSM modems. GRINS, our radio broadcast system at Gram Vaani, currently supports telephony over PSTN landlines and SIP VoIP. We will have SMS and cellular based telephony very soon: http://gramvaani.org/technology/community-radio/ cheers Aadi Kara Andrade wrote: Is anyone out there doing community radio using cellphones.

Re: [cr-india] Cellphone-based community radio
Hi, The AurovilleRadio is testing since December 2009 broadcasting trough cellphones connect with GPRS connections. It's working fine but you need a cellphone supporting Flash technology and for time being are expensive. If you have a Flash enabled phone connected with Internet you can log into http://www.aurovilleradio.org/mobile and listen the AurovilleRadio from all over India.
