If you see any advertisements from mobile operators, you will likely come across pictures of happy-looking people watching HD videos on multiple devices. It is important to make a distinction between peak data speeds and average data speeds.
The average 4G data speed is what you normally get on your mobile device, and the peak 4G speed is the maximum speed that is theoretically possible.
The peak speed of a mobile connection is the maximum data rate that can be extracted from the radio signal when using the highest possible network configuration. The maximum bit rate is what is sent through the cellular towers based on the network configuration. The bit rate received at the other end e. All that reduces the overall achievable data speed that mobile phone users get.
The best chances of getting the maximum speed would be if you were located very close to the cellular tower of your mobile operator and if your device was the only device being served by the relevant LTE tower. The maximum speed of 4G LTE networks depends on the network configuration. There can be various combinations of how the channel bandwidth and modulation techniques can be used.
When a 20 MHz channel is used with modulation of 64 QAM Quadrature amplitude modulation , top speeds of up to Mbps can be achieved in the download and 75 Mbps in the uplink.
The downlink data rate helps with downloads, and the uplink data rate supports the uploads. The average achievable speeds are considerably lower, which is what we will look at in this post.
Our speed tests used pay-monthly SIMs from five 5 randomly selected mobile operators around the world. However, most of these tests were carried out in the UK in Berkshire, Reading. The other table shows the download and upload speeds on an LTE network 4G.
Your mobile device has to do a lot of work to help you perform basic tasks e. Moving from 3G to 4G was a big deal for carriers, and it would take a series of network upgrades to get there, rather than one single jump. The problem with creating wireless standards is twofold. Instead of a technical standard like 4G, think of it as the means by which carriers took to match the official 4G specification.
Although all 4G LTE markets have passed this initial rollout stage now, some of these network types are still found in countries or areas with less developed infrastructure. If this all sounds a bit confusing, just look at the graphic below to see the sheer range of technologies out there. This was because many carriers and hardware manufacturers had already begun investing in these networks during the two-and-a-half-year deliberation.

This includes carrier aggregation to make use of more bandwidth at once and improved Multiple Input Multiple Output MIMO antennas to support this and improve cell edge coverage. Want something faster: The best 5G phones you can buy right now. LTE is the technology behind 4G. It stands for Long Term Evolution. It usually shows up on your screen as 4G LTE.
It was a standard developed when 4G was designed for the purposes of phones and towers and other devices to talk to each other. It is an open, interoperable standard used by virtually all carriers. All major smartphones use LTE today. In fact, there is no such thing as true 4G as defined by the standards set forth. Even if your phone is advertised as 4G, it uses LTE technology. LTE provides high speed mobile and broadband data, telephone service, and supports public safety functions.
In fact, the public safety network gets their own frequency on the LTE spectrum. LTE also has special features to manage the network. First, it can assign priorities to customers. Emergency calls get a higher priority for calls than someone like me.
If there are many folks on the network, the priorities will decide which call gets through first and which one might get dropped. One other feature of LTE is that it is a self-organizing network, meaning that if there is an outage, the calls will be rerouted to another path automatically and once service is restored, the network will revert back to its optimally designed path.
