CDMA stands for Code Division Multiple Access, which is a type of algorithm used in telecommunications to squeeze more usable channels within the same bandwidth. WCDMA is Wideband CDMA that still uses code division to divide the channels.

The most major difference between CDMA and WCDMA is in the group of technology that it is grouped with. CDMA is a 2G technology and is a direct competitor to GSMwhich is the most widely deployed what is the difference between gsm and cdma. WCDMA is a 3G technology that is often used in tandem with GSM to provide both 2G and 3G capabilities within the same area of coverage.

WCDMA and CDMA do not belong to the same line as the 3G technology of CDMA is called EV-DO and is the competitor to WCDMA. As indicated by being a what is the difference between gsm and cdma of the 3G group of technologies, you can clearly see that WCDMA can offer much faster speeds and take advantage of the more recent services that cannot be found within basic 2G.

WCDMA is also better suited for accessing the internet and emails compared to the very slow CDMA. As indicated by the word wideband, WCDMA uses a much wider bandwidth than that of CDMA. WCDMA uses frequency bands that are 5Mhz wide compared to CDMA where each frequency band is only 1.

Contrary to the popular belief that only the bandwidth has been changed with WCDMA, the differences between the are much bigger as WCDMA was designed from the ground up and was not derived from the CDMA Despite this, both technologies use code division to create a greater number of channels within the same given bandwidth and only the algorithms used vary and not the basic concept behind it.

Due to the much wider acceptance of GSMa lot of telecommunications companies who had CDMA and EV-DO networks are beginning to adapt the GSM and WCDMA technology. This is to allow compatibility with the greater majority and to open up the options of their subscribers in terms of handset options. CDMA is a 2G technology while WCDMA is a 3G technology 2. CDMA and WCDMA are not used together 3. WCDMA offers much faster speeds compared to CDMA 4.

CDMA uses frequency bands 1. CDMA and its successors are being phased out in favor of GSM and WCDMA. Does WCDMA has same network parameters as compared to GSM. For example, network MCC, network MNC, Cell ID, Location Area code etc.

Prior to reading this article I was always confused about the difference between CDMA and WCDMA technologies. I would like to convey thanks for taking pain to guide american casino book such an illustrative article.

Difference Between CDMA and WCDMA | Difference Between What is the difference between gsm and cdma

It is because of the differences between them in regards to the hardware they use to connect read article a network SIM card versus no SIM card. In simple terms, GSM handsets use what is known as a Subscriber Identity Module SIM card.

The more popular of the two technologies, GSM phones are found in most markets worldwide. GSM networks are currently the only type of network used in the UK and many other countries.

The SIM card itself is usually extremely accessible for the learn more here owner as well, usually placed what is the difference between gsm and cdma the phones battery.

It be removed and replaced easily, allowing owners to switch between networks without a what is the difference between gsm and cdma if the phone is unlock - which you can do through us if your GSM handset still needs unlocking.

Instead they connect to a network because that networks details are programmed into the handset itself. Therefore, when the phone is switched on, it automatically connects to the network whose details are embedded inside. Some of the most popular CDMA carriers networks are based in the US and include Verizon and Sprint.

Because a GSM handset uses a SIM card where the networks information is kept the phones also have a universally recognised SIM lock placed on them. This lock dictates which SIM cards the phone is allowed to work with. The process of unlocking a GSM phone is then made pretty simple. The SIM lock that each GSM device has is assigned an click to see more code when the phone is created.

This code is what we or any other unlocking company supply when an order is placed. The phone recognises this code and removes click SIM click to see more, allowing the phone to accept any compatible SIM card when it is inserted. CDMA phones have the networks information programmed inside as opposed to on a Amelia casino card, with therefore no SIM lock being needed.

The process of unlocking what is the difference between gsm and cdma CDMA phone what is the difference between gsm and cdma requires the use of software, where the unlocker can access the phones programming and tweak it to work with a different network.

This is literally done with a cable and a computer. Because of this, if the handset you unlock was created with GSM only, you will not be able to connect to a network that only provides a CDMA signal. Hi Darren, I have a question. Does the CDMA phones have a sim card slot or something?? I can speak to Verizon's phones all of there 4g phones are Hybrids supporting both CDMA, GSM, and LTE networks.

LTE is typically considered a GSM evolution path. Most of there phones 4G phones have gsm and cdma built in. And All of Verizon's 4g phones have sim cards and use OTA programming for both there cdma network and LTE network.

Even with the Verizon and Sprint the days of cdma are numbered they technically don't need the old tech for anything but are still using it. I have used unlocked GSM phones on verizons network the data LTE portion works flawlessly but they are still using CDMA for voice and text. Darren November 01, GSM Unlocking Because a GSM handset uses a SIM card where the networks information is kept the phones also have a universally recognised SIM lock placed on them.

CDMA Unlocking CDMA phones have the networks information programmed inside as opposed to on a SIM card, with therefore no SIM lock being needed. Was this article helpful? Rimal Jose November 26, Chad Matovu December 15, Brian Tuminelly June 15, Please sign in to leave a comment.
