How do cdma phones work

Every call data is encoded with a different key, and the calls are then transmitted at the same time. The receivers each have the unique key as well, to split the combined signal into its individual calls. Both are multiple access standards, which means that multiple calls can go through a single tower, but as you can see, the major difference between the two has to do with the way your data is converted into the radio waves that your phone broadcasts and receives.

There are, of course, more practical considerations that matter more for us as a consumer, which you can find listed below:. With the move towards 5G , the choice between GSM and CDMA becomes even less relevant, as voice call technologies increasingly moved over to data network brands. Today, the argument is only a consideration as 2G and 3G networks are still used at the backbone of network voice technologies.

Eventually, these bands will be repurposed and networks will move away from this older voice technology. Unless international roaming is a factor, as far as your voice call and 3G data needs are concerned, both GSM and CDMA networks are equally good, with factors like availability, coverage, customer service, and price, more at play here.

I want to use it with Verizon in the US. Based on what I read on your site, data should not be a problem. But what about voice calls? I guess the bottom line is, will this phone work on the Verizon network?

Will I be able to make calls and use data? It should work with Verizon. In fact, they plan on phasing out the CDMA network entirely by the end of Your email address will not be published.
