Hi,

So I have a Huawei B618s-65d from Spark for my wireless broadband plan. I'm attaining satisfactory speeds and throughput but I was thinking of trying to place it in the best position in my home. I am trying to understand the readings on the device information screen, and, using google which in turn takes me to a lot of wikipedia pages, it suggests my stats of:

RSRQ -7dB is within the range of 0 - -10 "Strong signal with maximum data speeds"

RSRP -105dBm is within the range of the router being completely disconnected???

If there's someone else who understands more about these readings I have more stats of

RSSI -77dBm

SINR 5dB

PLMN 53005

Judging by what I'm reading about most of these would the lowest reading possible be favourable in each section?

Thanks in advance, total newbie with this!

I've been running a number of tests on the B618s-65d on both Skinny (which uses the Spark network) and Spark.
What speeds are you getting?

I've been using this table as a reference - http://support.huawei.com/onlinetoolsweb/ptmngsys/Web/tsrev_ar/en/content/ar/34_edesk_3g_interface_failure_diagram/edesk_3g_edesk003.html

I've tested this on a B315s with external antenna's to see the difference and I see +10dbi difference which is exactly what the purposes of the antennas are for. I haven't seen any antennas for the B618s as yet.

So shifting it around the best I seem to get is about 23Mbps both ways which I'm okay with, was wondering about an external antenna but also wasn't sure it'd be ultra beneficial.. Moved it to an area where SINR was 15 which I thought was meant to be good and ended up with 0.5Mbit down, 17Mbit up so there are other values in play I guess

Will look at your reference you have there too, thanks

The antenna connections on this are TS9, seems like most stuff is SWA?

RSRP is the main one to look at. Ideally better than -105. Note the "-", so -100 is better than -110.
Also low SINR is better, that's related to noise level.

With 4G, a power level of -120 is like having 1 bar just in the old days. -120 should still get 5mbps up and down.

4G and 3G/2G are completely different.

The higher the RSRQ, the worse the signal, or bad quality.

RSRQ <-20
RSRP <-120

From memory btw

Actually just did some reading.. I was getting RSRP -120 @ 5Mbps when we used to test a few years ago.

I can't remember RSSI values..

What sort of area are you in?

Which wireless plan are you on?

Both these questions will drive your best step forward :)

Thanks everyone for all the info :)

I'm in Parakai, (auckland, I guess) on Metro Wireless with Unplan Entertainment. I've moved it around a bit and think I've found the best spot, like I said it's good for me.

I could get fibre but they've done a doozy for my lead in. It doesn't follow where the copper lead in come from (completely opposite side of house) and will get munched up by neighbours metal thread weedeater for sure (but that's another story)

Right, so your best bet is to log a case with the Wireless faults helpdesk.

they will raise it to tier 2 and look at options, one of these being an external antenna.

If it were a rural address i'd say just change to an antenna service :)

I've done a few MIMO antenna kits for Spark Wireless customers and they can make a huge difference. The biggest difference I've seen was for a customer in a brick house: before antenna approx 10Mbps, after antenna 90-100Mbps.

we do both ANT205 and the MIMO version (i forget the model for it sorry)

Does this involve someone coming out? Or can I do it myself? I do satellite & UHF installs as part of my job

Involves someone coming out. Obviously there is nothing stopping you from doing it yourself. field techs just know exactly where to direct it etc :)
