I-Mode, GPRS and (edit) 3G Questions


#1

Does I-mode use GPRS?

If so is it just some diffrent kind of software on the phone that makes it useful (ie, that “simplified” html thing)?

Is it just cool in japan because everyone has it?

What makes it better then Igogo?

Is it cheaper then Igogo (for downloading)?

I have more questions :shock: , but that’s all for now.


#2

What’s turbo igogo?

I"m going to stop reading about this stuff now, I’m just getting more :?

Does I-mode use GPRS?

Talking about Japan, maybe it’s different here. I-mode does not work on GPRS. But both use packet switching (always on) technology. GPRS, which came about from GSM uses a gateway, that means when connecting its handy-gateway-www-gateway-handy in that order. I-mode does not connect through a gateway. I’ve no info on how there’re doing it here. Is it on top of GSM??? But I doubt it. Anyone?

If so is it just some diffrent kind of software on the phone that makes it useful (ie, that “simplified” html thing)?

I-mode is not just a software, it’s the whole package, i.e phone, network, protocol, software on the phone etc. I-mode uses c-Html, which is a subset of Html. It’s not a software that you can download.

Is it just cool in japan because everyone has it?

No, everyone has it because it’s cool. There’re couple of reasons why it became so famous. When I-mode came out, it came with email. They had kind of an SMS thing, but it was pretty primitive. Just like in Europe, SMS took off, here it was I-mode/email. Then came the Java phones, you download games etc., then the camera phones, for taking pitures of your dog and sending to a dozen friends and now they’ve got I-mode on 3G networks, on which you can watch streaming video, news etc.

What makes it better then Igogo?

No idea what Igogo is!

But what makes i-mode really cool is, you get to browse the net, see pictures and mail, in color. I don’t think there’re any other system which you can do that. Plus, you can download value added content and apps., and they charge it to your phone. So you get really cool apps., games, porn ( :smiley: ) etc.

Does anyone have any info on I-mode and the network in Taiwan?

Thanks Jeepers, I’m understanding more.

Igogo is KGT’s GPRS thing. KGT (oops not KTW) is also the company that is setting up I-Mode here. The company that started I-mode has a 21% stake in KGT. So there trying to get it going.

Thanks for the link.

Anyway, besides the PR bullshit and line fillers, (KG Telecom is also the world’s first mobile operator to provide

I-mode is just a packet protocol that can read Compact Wireless Markup Language (CWML). I believe Igogo is a service based on Wireless Application Protocol (WAP) reading Wireless Markup Language (WML). I-mode allows graphics while WAP is limited to text. WAP can read a HTML, remove the images and serve the text portion to you. WAP didn’t take off as much as the hype did.
Japan uses the WCDMA protocol which is 3G. There are two competing 3G voice protocols, WCDMA and CDMA2000. Since I-mode also uses packet data technology, it should be able to be implemented on GPRS which is also another packet data technology. I-mode was implemented when NTTDoCoMo was in 2.5G which is the generation of GPRS.

They are not voice protocols, just radio access technologies providing high(er) packet data rates which can be used to carry voice (or serve data applications of course). A GSM network is circuit switched, thus one voice calls occupies on timeslot of the carrier at one base station. GPRS is an add-on to GSM networks, sometimes referred to as 2.5G and allows packet data for data applications (i.e. not for voice).

With 3G packet switched technology the resources can be shared between voice and data (max. 256 users per carrier), in fact the voice is data and thus all you need is a suitable protocol which can guarantee QoS (Quality of Service). Naturally the more users the lower the data rate - so don’t expect 2Mbit/s from a 3G network - unless you are the only user in that cell, standing close to the antenna and being stationary.

THIS page set me straight.

Lots of info here. I’m still readin it.


#9

OT but a quicky: Can you legally provide wireless access, e.g Wifi, as an ISP?

Someone told me Taiwan being one of few countries where they’ve banned commercial exploitation of non-licenced radio frequencies.

Anyone in the know?

Good link miltownkid, thanks.

Very good link indeed.

BTW, here the first Nokia 3G phone (sorry, “device”): nokia.com/6650_event/index.html

Because it took me so long to figure out I’m going to make me first FAQ.

Miltownkid’s How to get your T68/T68i email client working using TCC FAQ v.1.0.0.3

First buy a T68/T68i and phone plan with TCC.
Then your going to want to sign up for GPRS service (not e.WAP).
Now setup your the email client on the T68/T68i (pop, smtp, user name, password).
Make sure your email client is using the TCC GPRS data profile.
Now download your mail.
Easy huh?

It wasn’t hard execpt no-one at TCC understoond how there own service worked. There was a tech there that had it working on his phone, but didn’t understand why I couldn’t use it. He told me “The system is having problems, keep trying and it should work”. When all I needed to do was sign up for their data service and use the data service profile.

e.WAP and GPRS both use GPRS, but GPRS is faster and allows the user to connect a notebook or pda to the phone. So right now I’m paying 150NT for e.Wap and 150NT for GPRS.

I’m still going to turn it off and get a diffrent service. :laughing: But if anyone else tries setting it up (I recommend not), now you’re in the know.
