4G Anntena

Hi, folks I have been going mad! I have a Huawei B535 router CAT 7. I have glass french doors when I put my router outside, just about 3ft high I get about 88MB download and 14MB upload speed which is great! When I bring it inside directly behind the glass doors the speed drops to 30MB download and about 3MB upload speeds as far as I can make out I am on band 3 with Three mobile. I thought simply I will get an external antenna I just have to take it to the other side of the door. I bought a Poynting XPOL-1 V2 5G 3dBi Omni-Directional Cross Polarised LTE 2x2 MIMO Outdoor Antenna which made the signal worse. I have tried a couple of antennas and I can't get as good a speed as sitting the router outside! Any advice, please

Did you enable external antenna from the settings? Have you tried multiple locations?

Have you already tried a few other convenient locations inside the property? Sometimes unexpected and illogical locations can already give very good signal without needing an outdoor antenna.

It's often found that one side of a property might be better than another and generally higher is better due many obstructions being crowded lower down.

Windows are a bad thing for mobile broadband. You'd think because it's glass that RF would permeate better but it doesn't. I evidenced this point today with my parents MF286D, it was on the window sill, clear line of sight to the tower 300m away, 82dBm, but speeds would collapse within a few minutes of power on.
Moved the unit into the room on top of a computer desk, no longer LOS and behind a wall, went to 72dBm just because it was no longer directly behind the glass.

Also, the XPOL Omni's aren't that great. They're particularly low gain antennas with long lengths of cable. Basically, all the power and gain you've made in the antenna is then lost in the cable and it wasn't a lot to begin with. The only time you'd benefit is if you're sat on top of the mast with plenty of power available outside.

Best thing you can do currently, ditch the XPOL, take the router upstairs (if your able to) and test it on 4 sides of the property to see which side performs better.
 
For download speed, you want to locate the router or antenna for maximum SNR (SINR) rather than maximum signal strength. Due to heavy frequency reuse in 4G, the router is likely to pick up signals from more than one eNB, but only one is useful. So, unless you live in the middle of nowhere, there is a high likelyhood that you are receiving a lot of "noise" from other eNBs.
Omnidirectional antennas don't help in that situation.
 
Thanks, guys, I can't put the router in the attic I did try the Bluespot: 5G-ready outdoor antenna for UK broadband, 4G LTE-A + 5G it still was not as good as sitting the router outside. I have purchased a waterproof electrical box and put the router in it! so far this is the best solution. I am getting around 70Mb download and 20Mb upload speeds. I stay in a rural area with LOS.

I am getting
4G Frequency1392
4G Connected Band1800MHz(B3)
4G Signal Strength-94 dBm
4G ECIO/SINR17.4 dB
4G PCI298
4G Cell ID

If I find another solution I will let you know.

This is genius lol

Watch out for overheating in the warm season.

Good point.
I have a 4G router, but in a barn, so has a bit of protection. The PoE for the PTP radio tripped out the mains. In cold weather condensation had clung to the power lead and created a short between pins in the socket. So bear in mind routing of cables - not just for rain water but also for condensation.

I have bought one of those waterproof boxes that come with a gang plug - for xmas lights I guess. Will be putting 4G router and PoE injector in that to keep warm and dry.

Will have to think what to do in warmer months. Maybe just leave it open half the year?

Imho if it's not gonna be in the sun drill plenty of ventilation holes at the bottom (maybe cover them with insect net), if in the sun then some active cooling might be required.
 
Did you try it with the reflector horizontal? I’m using something similar but haven’t tried it vertical.
Disclaimer: This is my personal opinion from my experience.

I have always found a vertical polarisation with high gain antennas will almost always yield significantly better signal stats than horizontal.

Why?
My theory is that the antennas on the node mast are stacked vertically. This is to give high gain but also to present that power as a flat, wide angle beam to cover a wide sector.

You can apply the same theory for user antennas going back to that mast. I don't need a wide angle beam to send power back with, I need all that power concentrated into as small of a beam as possible to hit that node.

If you imagine my beam back to the node as it propagates from the dish in the horizontal position is wider than vertical, which means power is lost trying to hit that small, stacked eNodeB antenna. Whereas vertically, the beam is taller, but narrow, focusing more power at the eNodeB. It also reflects off the ground going back so there's just more going back.

It also helps to cancel out noise from other masts transmitting to the right and now left of this node.

Have to remember, I'm in a fringe area. Outside on my phone, I get if I'm lucky 120-130dBm on Band 20! If I drive to the mast, I have to get within 4/500 meters to get similar, 95-100dBm stats on Band 3 as what I get at home, 8000 meters away with that antenna just slightly higher than my roofline.

It just goes to show the difference that can be had with a really, really high gain antenna, decent cabling and lots of patience focusing and aiming 🤣

Thanks, Lucian but I am in Scotland, and overheating is not a problem :rolleyes: Seriously thanks for the advice I might have a new solution by then. Seamingly I have a 5G Cell Tower with LOS but have to place the antenna quite high.
 
I also thought this was interesting
5G connections in the UK
In the UK, we use a "non-standalone" or "NSA" 5G infrastructure. This means your 5G router first connects to the 4G network for authorisation before it attempts a 5G connection, and a 4G and a 5G connection must be maintained simultaneously for the internet connection to work correctly.

Because of the way 5G routers are designed, they will only use our antenna for the 5G connection, not 4G - these antennas are internal to the case, and not connected to the rear ports. If the 4G signal is weak, it will lead to dropouts on the 5G connection.

If you're experiencing 5G dropouts, move the router to an area of your house where there is some 4G signal (in addition to leaving it connected to the 5G external antenna).

Alternatively, you can have the router modified to get access to the 4G ports inside, and attach a second external antenna to also boost the 4G signal. We stock a number of pre-modified 5G routers here, or you can reach out to the team at router-mods.co.uk to make the 4G antennas accessible.

Thanks for the detailed info. I’ll give it a try.

I get nothing on my phone. Not a sausage!

Yeah that's pretty bad.

One of the reasons I'm looking forward to Three getting the mast nearby in Thurston online as it'll definitely have band 20 which might cover my area or better still band 28 such almost definitely will. Can hopefully get rid of my signal booster then
