Wifi transmits data at 2.4 GHz and 5 GHz radio frequencies. Whereas 3G transmits data at low frequencies ranging from 850 MHz to 1900 MHz. 6. Wifi frequencies are more stable than 3G frequencies.
The main difference between 3G networks and WiFi networks is range. ... Typically, WiFi provides a much faster connection speed than 3G. Because in most cases, there are only a few people using a WiFi network compared to a 3G network that is used by hundreds if not thousands of people in the locality.
Most of the time, WiFi is cheaper, more reliable, and faster for anything you need to do online. The only major benefit to Mobile Data is portability for access in areas without a landline internet connection.
To sum it all up, 3G network speeds were great for voice and data, while having some of the fastest download speeds available today. 4G LTE offers voice and data just like 3G, however, the download speeds are known to be almost twice as fast and also reach much further than the earlier 3G.
Both Wi-Fi and mobile data do essentially the same thing, and work together to let you access the internet, anytime, anywhere. The primary difference for users is cost. ... Wi-Fi only works within the range of its router, but it enables you to access data for no additional charge.
WiFi Is Usually Faster than 4G LTE Mobile Data.
There are so many situations where WiFi speed is much worse than mobile data. And it pretty much has to do with stumbling upon a bad (slow, non functional) WiFi hotspot to which your smartphone sticks – a.k.a. sticky WiFi.
Theoretical 5G speed
|Average speed||0.1Mbps||50Mbps and up|
WiFi for Android is a priority. If there is WiFi and Android Data, the WiFi will take over the data connection. However in order to use only Mobile Data, you need to turn off the WiFi manually.
This is located in Settings Cellular and usually is enabled by default in new iPhones. Similarly, Android phones also have such a feature that enables the phone to use data even when connected to the Wifi. Since Android phones come from a variety of manufacturers, the name and settings could vary.
Restrict background data usage by app (Android 7.0 & lower)
Unfortunately, the ability to access the 4G network depends on your phone's capability. So, if you have a 3G phone, you won't have access to the 4G network. ... If you're in an area where 4G is available and your phone is an LTE, your phone may bump down to access the 3G network.
4G is often up to 10x faster than 3G in real-world use – with speeds commonly between 20Mbps and 50Mbps (which is really fast). New 4G technologies such as "Carrier Aggregation" – where your smartphone connects to multiple cellular frequencies at once – can offer even faster speeds in certain areas.
The primary advantage of 4G calling is that it provides better call quality. The 4G network has more capacity and faster speeds which means more data can be transferred per second, equating to a much higher quality conversation. ... This is because 4G networks can react much quicker than a 3G or 2G network.
