What is CDMA Technology? How does it work? What is a CDMA Unlocked Phone?

How Cdma Works

CDMA is an Acronym for Code-Division Multiple Access, a digital cellular technology that uses spread-spectrum techniques. Unlike competing systems, such as GSM, that use TDMA (Time Division Multiple Access), CDMA does not assign a specific frequency to each user. Instead, every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence (truly random digital sequence isn't possible). CDMA is suppose to consistently provides better capacity for voice and data communications than other commercial mobile technologies, allowing more subscribers to connect at any given time, and it is the common platform on which 3G technologies are built (today may GSM phones also come with 3G technology).

CDMA is a military technology that was first used during World War II by English allies to foil German attempts at jamming transmissions. The allies decided to transmit over several frequencies, instead of one, making it difficult for the Germans to pick up the complete signal. Because Qualcomm created communications chips for CDMA technology, it was privy to the classified information. Once the information became public, Qualcomm claimed patents on the technology and became the first to commercialize it.

In the United States the best known mobile carriers who uses CDMA technology are Sprint, Verizon Boost Mobile, Altell at al. get it now Verizon is what some "verizonied" friends have told me. Verizon cellular or Verizon mobile technology sounds great but when I had it a couple of years ago I didn’t get great single on my Verizon lg or my audiovox cell phones. I had to constantly leave my house and stand in my backyard to talk to friends this left a bitter taste in my mouth when it comes to Verizon service but most of my friends who have it and live in "normal places" has they tell me have no problem with Verizon it works for them great. I've not written Verizon off completely after all my experience was at least 10 years ago and I m sure they've improved in my area. So if I start having problems with my currently company I will give them a try one more time (pre-paid of course) to test their service.

Verizon's FiOS takes Manhattan

NEW YORK - Verizon's fiber-optic service, so far mainly available to suburbanites, is making a big push into Manhattan with a deal to connect an 11,232-unit apartment complex.

Stuyvesant Town and Peter Cooper Village, an enclave of 110 buildings on Manhattan's East Side, is the largest apartment complex in Manhattan and the largest to get FiOS service anywhere in Verizon's 17-state fiber buildout area.

Verizon Communications Inc. announced the deal Monday, but seven buildings are already connected. It will take some months to connect the rest.

Single-family houses have been the low-hanging fruit for the company's $23 billion project to replace its copper phone lines with fiber optics. Connecting apartments is technically more difficult and requires permission from landlords.

Verizon gets cozy with P2P file-sharers

NEW YORK - Peer-to-peer file sharing, the primary vehicle for online piracy, has been as unpopular with Internet service providers as it has been popular with users. Providers have banned, blocked or slowed peer-to-peer traffic in their efforts to keep the flood of music, video, games and software from overwhelming their networks. But Verizon Communications Inc. has broken ranks with the industry and is set to announce Friday that it plans to help its users share files faster — at least those who do it legally.

With researchers at Yale University and a group of companies that make file-sharing software, Verizon collaborated to enable faster downloads for consumers and lower costs for participating ISPs.

File-sharing accounts for one-third of all Internet traffic, according to Arbor Networks, a maker of traffic-management equipment, and some estimates are higher.

Open Source Software Developers Sue Verizon, Claim FiOS Violates GPL

In what could become a major test case for the most widely used open source software license, a group that represents open source developers has sued Verizon Communications -- claiming that the telecom giant's FiOS broadband service violates the terms of the GNU General Public License.

In court papers filed Friday, The Software Freedom Law Center maintains Verizon's use of an open source program called BusyBox in FiOS violates version 2 the GPL because Verizon has not made the product's source code available to its customers--as the license requires.

Since November 2006, "Verizon has distributed to the public copies of the firmware in the infringing product, and none of these distributions included source code to BusyBox or offers to provide such code," SFLC alleges in its complaint, which was filed in federal court in New York.

SFLC says the offending software code can be found in Verizon's Actiontech MI424WR wireless router, a piece of equipment that's supplied to FiOS subscribers. The group filed the lawsuit on behalf of BusyBox developers Erik Andersen and Rob Landley.

Get smart: a guide to spiffy phones at Yahoo News

Apple Inc.'s iPhone has shaken up the "smart phone" business and set other manufacturers scrambling to add features and make it easier to get e-mail, surf the Web and enjoy music and movies on a cell phone.

Prices also have come down to the point where some of these feature-packed models cost little more than "dumb" phones. Sizes have come down too — gone are the days when carrying a smart phone was a workout.

Remember, though, that you need a data plan to get the most out of a smart phone, which usually adds about $20 to the monthly cost. (Prices below are with two-year carrier contracts unless noted.)
