What is 3G, 4G, and LTE

What is 4G If you own a smartphone, you undoubtedly have heard the terms 3G, 4G, and LTE. cellular providers such as AT & T and Verizon endlessly advertise they have biggest or fastest 4G net or LTE net. It ’ randomness difficult to understand how each company can make those claims. however, when buying a new smartphone, it is authoritative to understand the dispute. The type of data network can directly impact the performance of your smartphone .
When you buy a smartphone, you are typically required to sign up for a service plan that defines a certain sum of calling minutes and data custom. once connected to the cellular provider ’ s network, the smartphone can communicate with the external world to support features such as electronic mail, maps, and Internet browse. Many of the smartphone apps trust on sending and receiving data across the net .
When describing smartphone data networks, you normally hear the terms 3G, 4G, and LTE. This refers to the genesis of network engineering. The third coevals network, known as 3G, is the oldest technology of the group. 4G is the fourthly genesis data network and LTE stands for long Term Evolution. The basic difference between them is the speed of the network. When selecting a smartphone, the older models may not support the newer data network technology. It is authoritative to select a model that supports a data travel rapidly appropriate for your needs .

3G Network

The 3G network was the first gear engineering with sufficient speed to provide a decent user experience on a smartphone. There were some smartphones that used the older 2G EDGE engineering, but the data speeds were slow and the drug user spent a lot of time waiting for data to burden .
Each of the major cellular providers have 3G networks that provide coverage across most of the country. There are two competing 3G technologies presently being used : ball-shaped system for Mobiles ( GSM ) and Code Division Multiple Access ( CDMA ). AT & T and T-Mobile use the GSM engineering while Verizon and Sprint use the CDMA technology. Since the technologies are not compatible with each other, this is the reason you can ’ deoxythymidine monophosphate use a Verizon call on an AT & T network ( or frailty versa ) .

4G and LTE

The 4G technology is the successor to the 3G engineering. cellular providers are calm building out their 4G networks. Theoretically, 4G is much faster than 3G. But before we start comparing 4G accelerate to 3G speed, it is crucial to understand there are different versions of 4G .
When talking about 4G, things can get a little confuse. basically, there is 4G and 4G LTE. many people consider LTE to be truthful 4G technology. generally, if a cellular provider describes a 4G network without mentioning LTE, they are probably talking about a high speed Packet Access ( HSPA ) net. The HSPA network is a firm interpretation of the 3G GSM network. While not american samoa fast as an LTE network, it is inactive faster than a 3G network. Since LTE is still relatively raw, the cellular providers haven ’ metric ton amply built out their LTE networks yet. Be careful when looking at the net coverage maps on the providers ’ websites. Some companies claim to have broad countrywide 4G coverage. They may in truth be talking about HSPA coverage and not LTE coverage .
In theory, LTE can be improving to ten times faster than 3G. In practice, the actual network speed will vary based on network load and signal lastingness. even if LTE does not meet its theoretical accelerate, it is silent a lot faster than 3G. Activities that require big amounts of data, such as streaming movies, work very well on an LTE network. If you plan to perform a fortune of data-hungry activities or simply want the best operation when surfing the Internet, you should very plan on buying a smartphone that supports LTE .

What iPhone Models Support LTE?

If you are considering buying an iPhone, you will find five models available : iPhone 6s Plus, iPhone 6s, iPhone 6 Plus, iPhone 6, and the iPhone 5s. All these models back LTE. The iPhone 5 was the first model to support LTE and all models newer than the iPhone 5 patronize LTE. The iPhone models prior to the iPhone 5 do not support LTE. The iPhone 4s supports HSPA, which some cellular carriers call 4G. The iPhone 4 will only support 3G networks .
This page on the Apple web site compares all the current iPhone models.

When buying a newly smartphone, don ’ triiodothyronine be fooled by all the marketing hype about 4G and LTE networks. Understand the different network technologies available and try using the Internet on the smartphone before you buy. The LTE engineering provides the fastest cellular datum network available and the accelerate remainder between LTE, 4G ( HSPA ), and 3G can be quite noticeable .
