Hi there,

 

The optimum distance is 2 x Wavelength @ the Lower Frequency used, in your case 850MHz being 705mm spacing & you must mount the antennas @ -45Deg Main & + 45Deg AUX as that is how the 2 data streams are Transmitted/Received in 2X2 MIMO, this way you can achieve the maximum data speed possible, also note the arrow that indicates the top of the antenna must be pointing up too.

 

Hope this helps.

Hi there  @vk3hjq , a long message but please read. You're my last hope in this.

 

I'm running into trouble using MR600 V2 with Vi India operator. (Vi: Vodafone Idea two telecom operators submerged)

 

I can search for available 4G bands but I can't see band 41 listed. Vi is operating on 3 4G bands in my area which are band 3,8 and band 41 which has the highest speed. I can only see 5 bands every time I search under manual band selection which are band 1,3,5,8 and 40 always. Although it automatically does carrier aggregation with just one band selected like 40 in Jio operator and 8 in Vi.

 

This is really important for me to be able to lock band 41 as Vi is offering unlimited data in its postpaid plans where Jio has the highest speed in band 40 with 4G+ CA upto 103Mbps but with limited data plans. I've got upto 95Mbps in the router. But if I use Vi I can't get such high speed in band 3 and 8 which are listed when searching manually. I can lock on to band 41 in my phone with 'Network Signal Guru' root application but I can't even see it in my MR600 V2. It has the latest firmware installed version 1.5.0 0.9.1 v0001.0 Build 210914 Rel.59719n

 

I've seen in videos that MR600 V1 has different band selection options with a beta firmware upgrade where you can select band A and B and could even see band 41 listed in one of videos from my country and language then why MR600 V2 has limited features than its predecessor version V1? I scorched the TP-Link forums and could find official statement from TP-Link that it's not software related and it's hardware related (which I know already) and it cannot be fixed with firmware update. I checked the specifications and band 41 is supported by V2 but I can't find or use it. I feel like company is keeping us in dark and being shady about this they're not helping anyone with this. I couldn't find anyone who got success in this. Please help me if there's anything that can happen, I can't find any beta or latest firmware than already installed, I've emailed to them. I don't think they're gonna help me in this.

 

I think they removed band 41 intentionally as there were some reports about an error when trying band 41. Or if they haven't then V2 version just can't detect band 41. One more thought that I haven't mounted the antennae as per your guidance for band vise mounting due to limited hardware tools but I'm working on it and I'll mount them exactly when I'm ready but could this be a shot to see band 41 listed if I try horizontal mount with 2x lower band frequency or 2x band 41 frequency. Or I'm stuck with limited high speed data connection from other operators even when I could get unlimited data with broadband speeds :"(

 

Here the complete details:

 

Model: TP-Link Archer MR600 V2

 

Hardware version: Archer MR600 v2 00000002

 

Firmware Version: 1.5.0 0.9.1 v0001.0 Build 210914 Rel.59719n

 

Issue: Can't find band 41 under manual band selection

 

Operator: Vi India 4G

 

Band: FDD 41

 

Frequency: 2545 Mhz

(Is the frequency even in the supported band 41 range of MR600 V2?)

Hi, regarding the band 41 not detecting issue, it is because the frequency 2545MHz is not in the frequency range of B41 supported by MR600 V2, please check the specification on TP-Link India official website, the range of B41 supported by MR600 V2 is 2555-2655 MHz.

  @Sunshine 

Thanks for the reply. Well that's a bad news but thanks for clarifying. So there's no way for me to use this frequency range of band 41 in MR600 V2. Didn't TP-Link do enough research before starting the production? What other frequencies aren't supported by this router that operators use in some regions? What if operators are using slightly different frequencies for all the bands they're operating than those supported by the router. It'll be a useless then. What do I do now? Throw it away?

 

Let me tell you how much it can cost me if try to consume same amount of data I could on band 41 in Vi with unlimited data pack. Upto 10 to 20GB per day and for 300GB/month it would cost me $150/annum more than what this would cost me for the Vi unlimited data plan. And for peak limit upto 600GB/month, $430 more per annum.

 

That's what I'm gonna have to pay if I want to use same bandwith on the current highest speed providing operator. It's also same for what fiber broadband would cost me for a 100Mbps plan.

I can't get any good speed in other bands of the Vi India operator which has unlimited data plans.

 

My only hope now is that other operators introduce new unlimited data plans just like Vi. I don't wanna leave my place just for the internet and it's not even something I could've afforded.

 

Although extra $150 and $430 (total cost per annum would be $280 to $560) per annum isn't something I can't afford when paying in short instalments but this is still a lot for me from where I belong. I'm a student and part-time freelancer and it would be 20 to 40% of what I earn throughout the year.

 

Just think about this, $130 per annum vs $280 to $560 per annum.

That doesn't seem fair. Please do something about this. This is really important for me.

 

Could there be a firmware upgrade or could TP-Link upgrade the hardware of my device to solve this issue. Is there any tweaking I could do as I'm using external lpda antennae. Please don't tell me to contact local technical team they refer to email to TP-Link they don't have any solution FYI. I hope TP-Link can tackle this critical situation and won't let their name go down. Thank you.

Looks like you have your answer from tp-link support.

My Article/Post only refers to use here in Australia.

wow !!! what a nice article and full of info and explanations!!!

is it works similar to the MR400 V.4? 

im 2 km from the cell but my signal weak.
signal strength 25% 
RSRP - -96 dB
RSRQ - -19dB
SNR- -1.2 dB

i want to buy an omni 10 / 18/ 28 dB 4g antenna 
and i dont know with one will fit. i want to keep the budget low. 
shuld i buy antenna with 2 cables to connect to the main and aux or antenna with single cable and connect to the main only?


@vk3hjq 

thanks a lot!!

There is also a 2X1 MISO as well on Cat 4

@vk3hjq

I'm very impressed with your post on LPDAs and all the rest. That exceeds all my expectations and questions.

One trivial question remains though:

Is there any reason NOT to angle also the 2 little standard internal antennas at 45-135 degrees?

Thanks

Thank you for your email & the question.

 

Yes, angle them if your not getting 4G+

 

The antennas should be aligned this way regardless, @ -45Deg Main & + 45Deg AUX as that is how the 2 data streams are Transmitted/Received on 2X2 MIMO, this way you can achieve the maximum data speed possible.
