Phones TLA’s and FLA’s

[LadyInBed]

OK, I've just read the thread on laptops and phones, and have realised I am obviously not in touch with the jargon appertaining to the mobile phone industry.

So what is/are
HSCSD, GSM, GPRS, UMTS.
GPRS phones that support at least 3 timeslots down.

What other acronyms (appertaining to mobile phones) should I be aware of

Is there a mobile phone TLA / jargon buster web site

Should I go on a course

Am I just too old to take it all on board

Is the moon a balloon

Must confess nigel its all gobbledgook..trouble is these guys are good and cleaver at what they do..but dont seem to be able to relate to us that only know about brain surgery..know about the moon tho..its not a baloon its something the yanks
put up so they could invent nassa and make money.."Capricorn One"

Without wishing to bore you all too much

All info below from

http://cellphones.about.com/library/glossary/blglossary.htm

TDMA
One of the oldest digital cellular technology, mostly seen in North America. It is considered the less advanced digital technology, partly because of its lack of flexibility compared to other digital cellular technologies.

TDMA divides communications into packets of data based on timed transmission.


GSM
Considered the most advanced digital cellular technology, extremely popular in Europe and Asia. GSM networks are leaders in many typically "digital" services including the Short Message Service (SMS), Over the air (OTA) configuration and GSM positionning. Considered its technology and presence both in Americas and the rest of the world, GSM is in a good position for global roaming and many new GSM phones are called "global phones", since they can be used in virtually any country. The SIM card ("Subscriber Identification Module") is also a unique and essential component of GSM phones.

GPRS
A packet switching technology for GSM networks. It's an advanced data transmission mode that does not require a continuous connection to the Internet, as with a standard home modem. Instead, GPRS uses the network only when there is data to be sent, which is more efficient. The "GSM Association" believes using GPRS will enable users to send and receive data at speeds up to 115 kbps, more than two times faster than with traditional home modems.

HSCSD
One of the standards for high-speed data over GSM type of mobile phones. HSCSD establishes a permanent connection to the data network, which makes it more suitable for applications such as video-conferencing than GPRS, another high speed data technology. HSCSD delivers speeds of 38.4 to 57.6 Kbps, slightly more than what can be achieved with a regular fixed telephone system modem.

Also Known As: HSCSD stands for "High Speed Circuit Switched Data"

We also have wide band CDMA or 3G on the way but that's at least 12-18 months off (unless you are in the far east) so lets wait until then to worry about it.

A great site, and one I point all my new testers at is www.howstuffworks.com (where I copied the above from) it's fairly low tech explanations (links for the more techi of you) but gives a good all round definition of this sort of stuff

Yes, guilty as charged. The previous posting was actually industry chat from 3 guys in the industry. Its full of jargon, but just think what a newcomer to the world of sailing must think! It must be even worse than mobile technology.

Anyway, remember previous advise. Use a laptop for computing. Use a GPRS phone as a radio modem. Buy a GPRS phone from Motorola as they have been making them for about a year, and they are stable. You'll get faster data and smaller bills. Clear? No jargon?

Many thanks Tim . . .

Time Division Multiplexing - TDM
Pulse Amplitude Modulation - PAM
Pulse Position Modulation – PPM
Pulse Width Modulation – PWM
even Frequency Shift Keying – FSK do we still do that sort of thing?
Ah! They were the days . . .

Dont forget the

T39 and R520 from Ericsson
6510 and 6320 from Nokia

and, oh bugger think I'll shut up now before we get going again
