I read somewhere that the Silverdale Spark site goes through 1.6TB of data a week

Yeah the above PR says nearly 2Tb/week

What i find awesome is 2% growth A WEEK

Is there a difference between 4.5G and 4G+?

Because I've been seeing the 4G+ icon on my phone (Galaxy Note4) since early this year.

The last time I did a speedtest was a week ago and I got 190Mbps too.

Totally down to the icons your phone uses tbh...

i'm not up on what the icons are on the samsung UI

So going by the RSM site, it looks like these speeds would have been achieved by aggregating (potentially) 135 MHz of bandwidth:

20 MHz in Band 28 (758-778 MHz)

25 MHz in Band 3 (1830-1855 MHz)

20 MHz in Band 7 (or maybe Band 38 if TDD?) (2640-2660 MHz)

2 x 35 MHz in Band 40 (2300-2335 MHz and 2335-2370)

I'm only guessing the 65 MHz across Bands 3/7/28 is FDD and the 70MHz in Band 40 is TDD

No handsets capable of all this yet but some out there will be able to combine 2 or 3 of these to get several hundred Mbps.... quite what you'd use that for in a mobile device is another question entirely!

As an aside, (while looking at the RSM site), I'm impressed Spark has deployed 2300 MHz to around 50 sites already! (Although I guess they had to before the end of the year!)

I would think that existing 4G would provide more than adequate performance for most applications, but the increased capacity is very interesting as it will help to speed along the divorce proceedings between Spark and Chorus.
