Huawei b6168 / b818

I have a Huawei b618 simcard router.
Is it worth upgrade to Huawei b818

Hi there BSydd,

I had a 618 a while back gave me great results, I've had the 818 too but speeds were the same for me.

Guess it's all down to the masts near you that you can connect to though.

Here's a comparison you may find of interest, apologies if you've already seen it.

You'd think going from 4x4 mimo to 8x8 mimo would significantly improve your speeds. Guess its down to mast tech/contention more than what router you have then!

Yeah, I guess my 3 mast is still using damp string, but the damp string still gives me very acceptable results, mimo or not, but no difference for me speedwise between the 2 mentioned routers. :giggle:
 
AFAIK, no UK providers have deployed 8x8 4G antennas, so if that's the main attraction then it's not going to change anything.

Having checked the B818 a bit more, I don't think it's true 8x8, I think it's actually more like 2x 4x4, in that it supports 16streams from 4 aggregations, but maximum of 4 streams per aggregation - not 8 streams from 2 aggregations.

While the 3GPP Release 11 spec does define 8x8 MIMO, more than 4x4 antennas generally weren't available when the transition to (and therefore deployment of) 4G was taking place. Not many devices really had support for 4x4 it until the last few years, and use of rank 4 (all 4 streams of 4x4) on them is hard to get without perfect signal conditions so network providers didn't really have a reason to deploy it anything more than 2x2, at least until the last few years where UE support and data consumption is is rising.
Where 4x4 does help is on the cell edge as there is a bit more chance of receiving a stream compared to just 2x2.

The advent of 5G does bring benefits of higher than 4x4 antennas (8x8 and 32/64TRx MaMIMO) in that within the 5G specification it allows for beam forming to better target coverage to where it's required with a sub-set of an antennas' antennas. I don't believe the 4G spec had this, and so was relatively 'dumb'.
