There has been a boost in HSDPA speeds for some towers that I have seen. IIRC, the OnePlus 3 didn't support band 2 LTE.stev wrote:well my old ass oneplus 3 says '4G' but i noticed a drastic increase in speed since yesterday. normally i get 5 - 10Mbps download but now im getting 30 - 40Mbps.

4.4.3.v - The spectrum cap for the 1.7/ 2.1 GHz Band will be 30 MHz (i.e. 2 x 15 MHz) per cellular mobile operator, which allows for up to three cellular mobile operators.
Actually Digicel uses 2x2 MIMO and 256 QAM currently in their networkjoshuashah17 wrote:Actually for those wondering Digicel only uses Carrier Aggregation on their LTE-A network. 4x4 MIMO and 256 QAM isn't utilised as of now. Digicel's CTO said that the max speed is about ~190 mbps without the extra spectrum they were given for the lockdown. i.e. 10 MHz of band 2 and 15 MHz of band 4.
Factoring the extra spectrum given to Digicel for the lockdown they temporarily have a total of 20 MHz of band 2 and 20 MHz of band 4 which should give them a max speed of 300 mbps. Again Digicel doesn't use 4x4 MIMO or 256 QAM on it's network. I'm not too sure if they have Carrier Aggregation on the Uplink but I would assume so since they got over 50 mbps in some of the screenshots posted above.
As for bmobile they only have PCS (Band 2) deployed for LTE. They didn't purchase AWS-1 (band 4) to deploy LTE-A like Digicel. So bmobile's max speed is about 75 mbps without the extra spectrum they were given for the lockdown. i.e. 10 MHz of band 2. For the lockdown they were given an extra 10 MHz so they now have 20 MHz of band 2 deployed which should have a max speed of 150 mbps. bmobile may finally deploy LTE-A when TATT finally decides to give both operators access to band 28 (700 MHz).
For those who are curious you can use this LTE Speed Calculator: https://www.cellmapper.net/4G-speed to calculate the max speed that both networks can achieve given their spectrum allocation.

As far as UL speeds concerned, majority of phones can only do 64QAM and SISO on uplink, no UL Carrier Agg. The general user will therefore only get a max UL of 75Mbps.
The newer iPhones can do UL 256QAM and UL CA , meaning 100Mbps per 20MHz carrier, and for 2 bands, 200Mbps. Of course...the network must have these features enabled as well.
