5G Download Speeds
The average download speed on Three’s 5G network is 201Mbps, according to an Ookla analysis carried out in Q3 2020. This compares to 177Mbps on O2 5G, 152Mbps on Vodafone 5G and 135Mbps on EE 5G.
According to Three, they’re “building the UK’s fastest 5G network”. Their claim to this is based on the fact they have the largest amount of usable 5G spectrum: something that’s vital for transmitting data and for delivering high download speeds on 5G.
In total, Three currently has 140MHz of usable 5G spectrum. This compares to 50MHz on Vodafone and 40MHz on both EE and O2. As their 5G network is configured to use a single carrier of up to 100MHz in size, you can get download speeds that are up to twice as fast as what is available on other networks.
Three says they’re backing this up with a fully virtualised cloud-core network, multiple distributed edge data centres and next-generation radio access technology (64T64R Massive MIMO). This should help to give better 5G performance along with reduced latency and greater reliability.
All of Three’s price plans are offered without speed restrictions so customers can always access the fastest available speed. This differs from other mobile networks like Vodafone where you might need to pay a little more for uncapped download speeds on 5G.
5G Network Bands
In the UK, Three’s 5G network is using band n78 5G spectrum (3500MHz). If you’re using a 5G phone that was purchased outside the UK, you should ensure it supports 5G coverage at band n78.
Alongside their 5G network, Three also has a 3G and 4G network. This uses the following bands and frequencies:
