The future of gigabit LTE
Thanks to the Qualcomm Snapdragon 835 processor, the ASUS ZenFone 4 Pro is the first commercial smartphone with gigabit LTE support over cellular networks. How much faster is that data transfer than what you’re used to, and how can you enjoy it?
Just to cover the basics, gigabit is a measure of speed. Don’t confuse it with gigabyte, which is a measure of storage space. Gigabit LTE represents sending 1 billion bits per second, which is roughly 125 MB/s. Even on a certified gigabit LTE network, this is only a peak theoretical speed; in reality, you’ll likely get a little bit slower, depending on service provider, network load, geography, your location, and many other factors.
Many parts of the world are still working to get any kind of wireline internet access, nevermind gigabit speeds. The ZenFone 4 Pro quickly closes the gap with the PC internet experience, and enables access to a wide world of rich online multimedia. Low latency video calling, quickly buffering high-definition videos, instantaneous web browsing, and fast music downloads are just some of the ways you’ll be able to enjoy gigabit internet on the ZenFone 4 Pro.
If you take a look at some of the numbers that Qualcomm has crunched, you can see that even for networks advertising sub-gigabit peak speeds, this technology can still help you enjoy significantly faster video streaming, web browsing, and data transfer. This is because a key factor in gigabit LTE connectivity is 4×4 MIMO. That’s an antennae configuration whereby you have multiple input and multiple output points for data. Considering the alternative is funneling all of your data through a single antenna, this can dramatically increase your data flow over any network. The added bonus of being able to deliver data more quickly is less network congestion and improved speeds for everybody else connecting to a given cell tower.
Another key factor to gigabit LTE is carrier aggregation. This allows service providers to receive and broadcast on multiple wireless bands, particularly in short bursts. Collectively, this can provide more bandwidth than any single carrier could provide at a given moment.
The final piece of the puzzle is 256-QAM, or quadrature amplitude modulation. This is a clever way of sending two bit streams of data along the same frequency by modulating their transmissions slightly at set intervals. In the end, you get more data coming in on the same amount of network bandwidth.
The world’s wireless networks still have upgrading to do before gigabit LTE is everywhere, but you can rest assured that you’ll be ready for the future with the ZenFone 4 Pro in your hands.
