Cellular technologies have evolved enormously; one of the main developments is the rise of 4G technology. It’s a word that you’ve certainly encountered in your daily life, but what is 4G? And is Sony Xperia Z1s 4G capable? We will answer these and other questions related to Sony Xperia Z1s 4G technology in the following article.
Does the Sony Xperia Z1s have 4G?
Yes. Sony Xperia Z1s has all the requirements to support 4G networks.
How do you tell whether Sony Xperia Z1s is 4G-enabled or not?
Nowadays, it is unavoidable to own a 4G-capable phone, because most internet users require a good internet connection. To know whether the phone is 4G-capableor not, you can use multiple ways.
An easy way when you hold the phone in your palm is just turning on the cellular data, if the Sony Xperia Z1s 4G data is on, then you will notice a sign at the top of the screen, in the signal bar. It might be 4G, 4G+, LTE, or LTE+ according to your carrier.
The absence of that icon means that you are not using 4G at that specific moment, and it doesn’t obligatorily mean that your phone doesn’t support 4G. And that takes us to the second option.
Check your phone specifications on the manual, or in the phone box. If you lose both of them, you can still check that on the official website (or any other credible website) using the device name or model number.
Another way is to check the settings: Go to your settings and find network mode, usually as follows: Settings > Cellular (or Mobile Data) > Cellular Data Options (or Mobile Data Options). If your phone is 4G-capable you will find a 4G or an LTE option. If you don’t see either of them, then your smartphone isn’t 4G-capable.
How to switch to 4G on Sony Xperia Z1s?
If you would like to switch on your Sony Xperia Z1s 4G network, then follow the instructions (it might vary a bit from the settings on your own device):
1- From Home screen, choose Apps.
2- From the Apps tab, tap Settings.
3- Under Wireless & networks tap on “More…”.
4- Choose Mobile networks.
5- Make sure the Mobile data traffic is checked.
6- Tap Network Mode.
7- Choose 4G or LTE option.
Note: If you intend to turn off 4G then choose a lower network type (3G for example) or tap Only 5G if it’s possible.
Introduction to 4G technology on Sony Xperia Z1s
The International Telecommunication Union (ITU) is the entity that defined 4G in the first place, 4G is the fourth generation of wireless technologies. It comes just after 3G and preceding 5G.
4G has very high internet uploading/downloading speeds, ten times more than 3G, Which is enormous. It also has 50ms latency, much less than 3G.
4G is not just one technology, but a set of technologies compatible with ITU specifications. It includes LTE, LTE+, and HSPA+.
What distinguishes 4G on Sony Xperia Z1s?
4G was created to deliver a more reliable internet connection on phones, and that’s clearly what it did. 4G technology serves much better downloading and uploading speeds than 3G.
The average 3G speed ranges from 1.5 to 9 Mbit/s, while the average 4G internet speed ranges between 15 to 90 Mbit/s, it can reach as high as 900 Mbit/s.
Another significant criterion of 4G, is its low latency. We can simplify latency and say it’s the time needed to transmit data or the delay between the action and the actual execution. Lower latency means a better user experience. 4G has 100% better latency than 3G. The average 4G latency is 50 ms.
With the assistance of the VoLTE standard, 4G now provides better voice quality in phone calls and gives users the capability to surf the internet while making calls.
All of these advantages combined with the low cost of 4G extended the use of Sony Xperia Z1s 4G technology, to include better video conferencing, online gaming, and other real-time interactions.
Get to know 4G bands in the Sony Xperia Z1s
4G and other cellular networks use radio waves to transmit data. These waves have different lengths and frequencies. To prevent interference between signals, governments and the ITU decided which regions use which frequencies for 4G.
Each region has been allocated certain frequency intervals termed bands. Band number 7 and band number 28 (for example) are used at the world level.
What you should know as a consumer is that each mobile provider offers certain bands according to the area, and different phones enable different bands. So you should make sure that your Sony Xperia Z1s supports the bands offered by your local cellular provider.
Here are the Sony Xperia Z1s4G-enabled bands:
