Using a wilson booster with my t-mobie 5G home internet gateway

One thing to consider is that a booster will receive the same signal and just amplify it. If the signal is weak and gets weaker well it can only amplify what it receives so a signal that is poor quality and suffers from RF noise is probably not going to be much better boosted. Keep in mind if you get a signal booster the cost is pretty steep for a good one. The 5G millimeter-wave frequencies (28, 37 & 39 GHz) are not handled by current boosters and it will be a while (2-3 years) before that is the case. Cellular boosters have been intended for cell phones. With the millimeter say the n41 the MIMO operation is not handled by the current generation of boosters. You would probably be better off with an external antenna than a booster. I suggest you investigate the antennas that Waveform has and talk to their engineers. They are very helpful and have some solid antenna solutions both 2x2 MIMO and 4x4 MIMO and have some guides and assistance available to customers. 

My sister needed a 4G booster and I installed a weBoost for her which works for her 4G needs but that was still pretty expensive and still limited capability.
