Can I bypass a cell tower using a directional outdoor antenna?

Post by websiteperson » Wed Mar 24, 2021 2:05 pm

We have 3 VZ cell towers within range of our house. One is 2.2mi away, SE of us, which gets very congested. It seems to only have bands 2 & 13 on the side that serves us. I've occasionally seen speeds up to 45mbps during the day, but it drops to <1mbps every evening.

There's a tower 5.4mi away, South of us, that I can only pickup outside (0-2 bars inside), and only band 4/66 from this range. It also has band 2 if close enough, and probably band 13. I consistently get 7-20mbps in our backyard, when on this tower.

I ordered a couple of the triangular shaped Wilson yagi antennas to connect to my LB1120 modem, in hopes that I can latch on to the tower to the South. If I recall, these have a wider beam than some other more directional antennas, so I may not have any luck at all.

There's also a tower somewhere North (according to cellmapper) of us that I can connect to, but I can't seem to pinpoint it's location. I will try when the antennas arrive.

Back to my question... can I bypass the closer tower, or will it connect us to it still, because of the internal antenna on the LTE modem? Supposedly it doesn't have one, but I can get 3 bars of signal without external ones. 🤷‍♂️

Also, would I be able to receive band 2 on the other tower? Obviously, with the closer tower having band 2, it won't let me connect to the one farther away on that band, with just my phone.

Here are the 2 tower locations:

Possibly. You need the highest dBi antenna you can afford. The higher dBi means a tighter beam; basically. You want an antenna to be like a laser beam. You also should shield the antenna, if you can, in the direction of the other tower.

If you built your own router with a Quectel modem, you can lock the modem onto the tower of choice.

Didneywhorl, I am also interested in locking a modem to a tower...at the least for testing purposes. I have an EM-12G, so I'll look up the at commands elsewhere, but I am assuming the only way to know where towers are is just drive around with my laptop on the passenger seat? :lol: I did this once not too far from home, and sure enough I sparked trouble with neighbors wondering what I was doing :oops:

Can you recommend an app to simplify this process? I have android, windows, and mac.

I have done this. Also sometime might need to lock out lower frequencies from unwanted tower to be picked up. For example needed to block out band 13 on Verizon before cause it kept picking it up. After that it was fine.

Understanding cell tower IDs from Cell Mapper and the output from the command

Code: Select all

AT+QENG="servingcell"
and

Code: Select all

AT+QENG="neighbourcell"
will help you get the info you need for the command:

Code: Select all

AT+QNWLOCK=?
That command, above, will give you the format you need. Look it up on this forum for more posts and details already spoken about.
