Rumored Verizon iPhone crippled on CDMA … for now

http://www.tehrantimes.com

Verizon's to-be-announced iPhone, which is still just a series of unending rumors at this point, is going to be crippled if it actually debuts on Verizon's CDMA network as-is. The Wall Street Journal is continuing its Verizon iPhone madness coverage with the news, which should come as no surprise to anyone with the slightest bit of mobile technical knowledge. Here's the deal. Verizon—right now—operates a CDMA cell phone network across the United States. AT&T, the sole holder of the iPhone at this point, runs a GSM network—Global System for Mobile Communication, for short. Without getting too far into the technical aspects of each mobile standard, it's enough to know that CDMA doesn't allow for simultaneous data and voice transfers. GSM does, which means that AT&T iPhone users can currently enjoy the privilege of talking to their friends and surfing the web, if they so desire. Were the iPhone to be released on Verizon's network today, that would be an impossibility—it's voice or data at any given time, not both.

Rumored Verizon iPhone will be crippled on CDMA

Despite the fact that rumors about a Verizon iPhone have recently gathered momentum, especially with The Wall Street Journal (WSJ) fervently publishing a series of articles about the iPhone’s CDMA version, tech experts are of the opinion that the prospective Verizon iPhone will be crippled. According to PCMag’s David Murphy, people who have certain knowledge of mobile technology will know that the CDMA network, which Verizon runs, presently has a limitation that it does not allow for simultaneous data and voice transfers – an advantage that the GSM network of US’ sole iPhone holder, AT&T, boasts.

Even though the WSJ reports say that Verizon intends incorporating the simultaneous voice and data accessibility into its network at some point in the future, there has been no official disclosure about the carrier’s timeline

Will Verizon iPhone Jump on the 4G Bandwagon?

http://www.pcworld.com

The rumors and reports surrounding the impending availability of the iPhone through Verizon are becoming more relentless--perhaps hinting that the speculation may soon, in fact, become a reality. Assuming the Verizon iPhone reports are authentic, the question remains how Apple will make the transition from GSM to CDMA, and whether the Verizon iPhone will embrace Verizon's cutting edge 4G LTE network. AppleInsider reports suggest that Apple will implement a dual-band chip from Qualcomm that will allow the iPhone to work on both GSM and CDMA networks simultaneously. This approach makes sense from the standpoint that Apple would not have to develop and manufacture separate iPhone hardware for each wireless network. It would also mean that a CDMA-compatible Verizon iPhone would still have international functionality as most of the world relies on GSM. With the recent Verizon announcement that it will soon unleash its 4G LTE network in major markets around the country, some wonder if Apple should not even bother with a 3G CDMA iPhone, and simply get onboard with LTE.
