Have you personally built a network using LTE routers?

I am setting up a 4G proxy server using LTE routers. When connecting 50 routers in one location, the LTE data speed drops to 300kbps. However, when reducing the number of routers to 10, the speed ranges from 3Mbps to 6Mbps.

I need to connect at least 50 routers in one location.

1. Has anyone used a 4G LTE signal booster or any other method to solve this issue?
2. If you have successfully used a 4G LTE signal booster, can you recommend any specific equipment?

Signal boosters are usually complete bullshit.

1) What kind of routers do you use?
2) Do you connect your routers to 1 PC/Server or are they working and connecting independently?
2) Do you use extrernal antennas ?

Probably your local mobile cell is overloaded or has to small capacity for 50 routers.
You need to run multiple networks tests to determine the problem.

I want to start right away with lte 5J, did you hear?
