LTE (4G), GSM (3G & 2G), CDMA (3G & 2G), 5G and ISM. The fundamental differences between these four modern technologies is the way they transmit and receive information. LTE (Long Term Evolution) is a 4G communication standard designed to be 10x faster than standard 3G. ... CDMA stands for Code Division Multiple Access.

3G Networks are based on WCDMA i.e. Wideband Code Division Multiple Access, a mobile technology that improves upon the capabilities of current GSM networks. ... WCDMA networks provides max 384kbps speed while HSDPA allowed speeds above 384kbps, the most notable of which is 3.6Mbps and 7.2Mbps.

Verizon's 4G LTE downloads are often faster than AT&T or T-Mobile's 5G speeds. The main takeaway from all the measurements seems to be that even though T-Mobile boasts with its triple-layer 5G spectrum cake, its full deployment is yet to materialize.

GSM stands for Global System for Mobile communication. ... One of the biggest differences between these two systems is that GSM phones use SIM cards to link a particular phone with its network, while CDMA phones don't require a SIM card because the phone itself is linked to the network.

5G Offers Greater Capacity A major difference between 5G and LTE will be 5G's use of a higher frequency bands, operating at millimeter wave (mmWave) bands on the radio spectrum, in conjunction with lower band spectrum. ... However, 5G traffic will share certain bandwidths with the existing LTE network.

What's the difference between 5G and 4G LTE? With 5G, high amounts of data can be transmitted more efficiently than 4G LTE. That means stronger network reliability, faster downloads, and support for more connected devices than ever before.

A. On a typical 4G LTE network connection, your data is encrypted and your identity is authenticated and protected. Wi-Fi networks, on the other hand, can vary widely when it comes to security. ... Although 4G LTE connections are generally considered more secure, the software is not impenetrable.

The primary difference between 2G and 3G networks for mobile subscribers is that they get to enjoy faster Internet browsing and data downloading on 3G. On average, the speed of data transmission on a 2G network is only 170Kbps, while in 3G networks the downloading speed can go up to 42Mbps (or 43,000 Kbps).

In theory, LTE can be up to ten times faster than 3G. In practice, the actual network speed will vary based on network load and signal strength. Even if LTE does not meet its theoretical speed, it is still much faster than 3G. ... LTE = Long Term Evolution is a 4G technology but it came into use as 3G was on cusp of 4G.

LTE stands for Long Term Evolution. It's a term used for the particular type of 4G that delivers the fastest mobile Internet experience. You'll usually see it called 4G LTE. Using a 4G smartphone on Verizon's 4G LTE network means you can download files from the Internet up to 10 times faster than with 3G.

The method chosen by GSM is a combination of Time- and Frequency-Division Multiple Access (TDMA/FDMA). The FDMA part involves the division by frequency of the (maximum) 25 MHz bandwidth into 124 carrier frequencies spaced 200 kHz apart. One or more carrier frequencies are assigned to each base station.

WCDMA is also called UMTS and the two terms have become interchangeable. Some parts of the WCDMA are based on GSM technology and the networks are designed to integrate the GSM networks at some levels.

So the reason your phone says LTE is because you are in an area that has the fastest internet speeds. When you are in an area in which your phone says "4g" it's because you are using a cell phone tower that has the slower, HSPA, internet speed.
159717
The first LTE networks and handsets only made use of a single 20 MHz carrier band, but LTE-Advanced introduced mixed carrier bands across LTE networks. ... With Gigabit LTE, five or more LTE carrier bands are aggregated together to provide the higher peak data rate.
465381
LTE (Long Term Evolution) is a 4G communication standard designed to be 10x faster than standard 3G. ... GSM is a digital cellular technology used to transmit data and voice communication at a frequency range of 850MHz to 1900MHz. GSM technology uses a Time Division Multiple Access (TDMA) technique to transmit data.

The basic difference between the CDMA and WCDMA is bandwidth ,CDMA uses 1.25 mhz frequency bandwidth while WCDMA uses 5 mhz bandwidth. Again CDMA is 2g telecommunication standard and provide very less data rates compared to WCDMA which is third generation technology.

The difference between unlimited data and 1GB of LTE data is all in the speed. You will have 1GB of fast, 4G data, which means increased download speed and connectivity. Once that GB has been used, you'll still have an unlimited data connection, but download speeds will be slower.
