Nokia Plans First Single-Chip GSM Phones
Jan 24, 2005, 12:25 PM by (staff)
Nokia today announced a collaboration with Texas Instruments (TI) to deliver the world's first phones with all major radio and processor functions consolidated onto a single chip. TI's single-chip solution, which reached the sampling stage last month, reduces overall phone cost and size, while increasing battery life. The first single-chip Nokia phones will be voice-centric, entry-level GSM/GPRS models. Existing phones require mutliple chips to handle logic, memory, power management, baseband, analog, and RF processing functions.

Benefits?
What type of benefits could we see from having a single chip phone, or somewhat single chip phone, aside from better battery life? Thanks in advance.
Other than the battery life, you will see much smaller phone designs, or phones that are similar in size of todays phones but will have room for other chip sets. including gps, wi-fi, bluetooth, etc.
as mentioned elsewhere, reduced cost, smaller size and lower power consumptions are benefits but there are others.
This solution will enable vendors to put more features into phones (like wifi, gps, bluetooth, multi-mode receivers, or better proces...

Not Single Chip
This is very cool but its not exactly a single chip phone.
You still need a PA, power management chip and memory. You'd also need an application processor if you wanted a feature phone.
Now that i've clarified that, i must say i am happy to see this. They've been talking a single chips transceiver since the mid-90's and here it is. I assume its RF CMOS. I wonder how well it performs? Some of the transceiver chips which have been replaced were usualy made from bicmos or bipolar processes which used to offer better performance.

True. This diagram illustrates it pretty well:

More battery life and less expensive. Sign me up.
Don't jump up and down yet. Nokia and TI's first foray into CDMA chips hasn't exactly produced the greatest results according to some analysts (...
