|

Not exactly sure where to put this, but the LG CU500 is out
with limited availability in HSDPA markets from Cingular.
Current issues are bluetooth 1.1 DUN and no mac drivers for
the USB cable. Prices are around $150 for a 2 year contract
or $300 for purchasing out of contract.
From what I've heard, the major plus to this phone is you can
talk and still surf at the same time thanks to carrier multiplexing. |

Nice, as long as you're continually in an area with updated towers. Once out of an area with same-time voice&data support, you're back to GSM voice or GPRS/EDGE. |

Me thinks that simultaneous voice/data on phones will be a significantly desired feature when realized by road warriors. Our staff needs a separate data card so they can talk on cellphone at same time when looking up client accounts or doing remote support. To have the phone charge while talking and doing data via USB, it will nix the need for a data card. Bluetooth 2.0 will provide even more freedom.
There are ways CDMA carriers can do this but it might be limited.
- Qualcom may do a dual CDMA chipset with two ESN numbers, one for voice and the other for data. Carriers haven't committed though.
- VoIP over Rev A will allow this but could be a couple years a way.
- Sprint may do dual CDMA/iDen phones where voice can be done over iDen while data over CDMA (or voice over CDMA if not needing to do simultaneous data). This may actually be available by end of the year to early next. But for those who also want a smartphone, it may not be an option down the road.
If the CDMA carriers don't find a way to compete with this by the time HSDPA is broadly available, Cingular just might become our preferred carrier. But at this time, Sprint and Verizon are way ahead of Cingular in deployment and might be for at least another year. |

That LG CU500 looks a little like a razor.
Odd that is would have 900/1800 MHz GSM frequencies, but lack UMTS/HSDPA 2100 MHz. So no data roaming in countries using 2100 MHz (discounting of course that it'll be SIM-locked).
Perhaps 2100 MHz complicates the antenna engineering/efficiency.
I still wonder how rural areas and lower-density cities will be treated. Mobile professionals move beyond the city, after all, so it will be interesting to see how everyone embraces the new-world stuff only to realize that their old-world working methodologies still have to be employed when they roam out of UMTS/HSDPA. |

I have developed RF network equipment for CDMA in the past and am currently doing so for UMTS/HSDPA. Perhaps I can shed some light on concurent voice/data capabilities of both.
Both the CDMA and UMTS/HSDPA standards support concurrent voice and data calls at the same time. The question is whether a) the handset you're using support it, b) the network equipment you're communicating with support it and c) whether the network operator has enabled it.
I wouldn't expect a two-ASIC solution for concurrent voice/data as it is already supported in standard and a single ASIC that supports the release that defines concurrency is all a manufacturer would have to do to make use of the capability. Would expect this to apply to both handset ASIC and base ASIC designs. Qualcomm's current CDMA ASICs being sold do support this, but when the network equipment manufacturers begin to implemented it at the network level is a good question I don't have an answer to.
Last heard, Nortel and Motorola had not yet implemented it, but my information is a year old. I can't speak of other manufacturers. Does anyone have more current information from a design source?
If Cingular has deployed this feature over UMTS/HSDPA, it would be indeed very nice to have.
Has anyone actually made such a call yet over the Cingular network? |

I just recieved my CU500 and am in the process of activating it.
I was surprised to see no 2100 MHz support as well.
I'm assuming I can still use GPRS over 900/1800 while outside North America. Does anyone know if EDGE is available on 900/1800, generally speaking? Is UMTS being solely deployed on 2100MHz outside North Am?
Thanks. |
