The technology described in UMTS is sometimes also referred to as Freedom of Mobile Multimedia Access (FOMA) Users in deployed networks can expect a transfer rate of up to 384 kbit/s for Release '99 (R99) handsets (the original UMTS release), and 7.2 Mbit/s for High-Speed Downlink Packet Access (HSDPA) handsets in the downlink connection.
These speeds are significantly faster than the 9.6 kbit/s of a single GSM error-corrected circuit switched data channel, multiple 9.6 kbit/s channels in High-Speed Circuit-Switched Data (HSCSD) and 14.4 kbit/s for CDMAOne channels.
I do not expect the new information to be available until mid February.
The problem is, as I’m posting this—the calculator is down.
You can use this guide for now and you can always tweak your withholding later when it’s back up.
UMTS combines three different terrestrial air interfaces, GSM's Mobile Application Part (MAP) core, and the GSM family of speech codecs.
The air interfaces are called UMTS Terrestrial Radio Access (UTRA).
For example, let’s say you’re single with 2 kids, you’d claim single 3 allowances; one allowance for you and one for each of the children.
