Today we’ll be discussing CDMA Handsets. The information below is a collection of data gathered from various resources to become a complete CDMA Handsets guide. Hope you enjoy!

As you probably already know, the wonders of technology always seem to amaze me as to of what small tech gadgets can do. It often reminds me of the Sci-Fi movies from our childhoods. My favorite was “Back to the Future” starring Micheal J. Fox. You begin to wonder and think about how a slim electronic hand-held device can do so many things and all while keeping you connected to the internet without wires.

The mobile market is certainly becoming more and more relevant. Mobile handsets have always been in our future, but the speed at which they are advancing is staggering. They have now become modems for our laptops and PC’s to access the internet. The technology of CDMA is allowing us the ability to have our phones be a “hot spot” for your computer. Thus, reducing the need for wires.

CDMA stands for Code Division Multiple Access. It’s a new technology competing with Global System for Mobile (GSM). (Click to read: CDMA Handsets vs. GSM Handsets)

When I talk about the future you’ll notice I always mention mobile. Weather it be mobile phones, or laptaps, or tablets, or even the old-school pagers and beepers… I believe mobile is where it’s at.

I remember when Apple CEO, Steve Jobs announced the highly anticipated iPad and told the crowd that Apple had reached the $50 Billion per year mark. Much of this staggering number is supported by the sales of mobile devices such as the iPod, iPhone and laptops like the MacBook. With the introduction of the iPad, Jobs went on to say Apple is no longer a computer company. “Apple is a mobile device company. That is what we do.” Jobs says Apple is the number one mobile device company in the world. All within a fairly short amount of time. They practically came out of nowhere in terms of the mobile industry when they launched the iPhone, which has gone on to redesign the entire mobile device industry altogether.

Those who understand the basic concepts of data communication know that using more than one transmitter to send information packets over a single communication channel simultaneously is common. This is the catalyst of CDMA and is often referred to as multiplexing which allows several users to share a band of frequencies at the same time. Kind of a cool concept and reality if you think about it.

In terms of CDMA handsets, they are basically the mobile handset or cell phone used by the CMDA. They are the physical handsets we carry around with us. Like some of brands shown below. It allows us to communicate with others via mobile phone.

Major CDMA Handset Makers
1. Nokia
2. Samsung
3. Motorola
4. LG
5. Blackberry

CDMA handsets are used all over the globe as the technology era expands.

Below you will find graphs showing the significance in CDMA handsets.

As you can see, the United States is not leading in the mobile frontier. In fact, the US is only catching up. Many parts of Asia have been using this technology for years.

CDMA was originally a military technology first used in World War II by English allies to foil German attempts at jamming communication transmissions. CDMA allows you to transmit over several different frequencies so the allies were able to maintain communications while making it difficult for the German enemy to pick up the complete signal. At the time, Qualcomm, a California based company involved in wireless research and development, was privy to the classified information due to their relationship with the governmental military divisions. They acquired the patents to the technology once it became public and was the first to commercialized it. Today, Qualcomm still allow mobile manufactures to apply CDMA technology to their products worldwide. It’s becoming one of the most widely used technology in the world.

CDMA mobile uses a special type of digital modulation called Spread Spectrum. Think of it as occupying the same frequency at the same time as your peers, thus being able to talk at the same time rather than one at a time all walkie-talkie style.

This of course is a generalization, but I’m sure you get the idea. CDMA technology has evolved into CDMA handsets for our future. Am I telling you something new? Maybe not, but this is one technology I will be keeping my eye on as the mobile frontier takes leaps and bounds never seen before in the era of international communication.

Okay, which one is better? GSM Handsets or CDMA Handsets — let’s find out!

What is CDMA?

CDMA stands for Code Division Multiple Access. First developed during World War II by English allies to foil German attempts at jamming communication lines. CDMA allows users to transmit communciations over several different frequencies. It’s a digital modulation called Spread Spectrum.

CDMA Advantages:

  • Cost less. Consistently lower priced compared to GSM.
  • Currently, the call quality is better as compared to GSM.
  • Offer economical services and are a urban market hit.

CDMA Disadvantages:

  • Less variety of handsets as compared to GSM.
  • Incompatible with GSM handsets.
  • Can not offer international roaming.
  • No SIM card. Have to stay with the same phone for a long time.

What is GSM?

GSM stands for Global System for Mobile. It was developed in the 1980’s as a new technology to advance both signaling and speech channels to new levels of digital.

GSM handsets use SIM cards which are small detachable smart cards containing the user’s important subscription data/information. This is what some indicate as the the main advantage of GSM handsets as compared to CDMA handsets.

Advantages of GSM service:

  • SIM cards. Removable smart card containing subscription info.
  • Roaming. Talk anywhere in the world.
  • Variety of handsets & service providers are available to choose from.
  • Call quality is comparatively more secure & better.
  • More stable network and robust features as compared to CDMA.
  • Power consumption is less than CDMA handsets.

Disadvantages of GSM service:

  • Higher cost. Roaming call costs are almost always higher than CDMA handsets.
  • GSM phones are not full proof & and can be tampered with.
  • There is the chance of losing all your data if the SIM card is lost or damaged. (No physical memory)

In the end, most people choose GSM handsets due to better facilities by the operators. That’s what I did. I chose the GSM handset. It’s a more stable and robust network. However, CDMA is certainly in the mix. It’s a growing network and one to keep an eye one in the long haul.

As you can imagine, one reason I prefer GSM is because of the SIM card. I like the capability of being able to transfer the SIM card from phone to phone and still have access to the system. Whereas, with the CDMA handsets the memory is all held on the device so it’s not as flexible. Also, I’ve found GSM as the pioneer of the text message craze. It is at the frontier of SMS and MMS messaging. These services will become more and more demanded as multimedia hits the mobile market in mass.

The handset segment of the mobile industry will continue to bloom over the next decade. No doubt. In my opinion, GSM will be at the frontier of this future technology.

So there you have it. GSM handsets vs CDMA handsets. Which will you choose?
