As far as congested areas are concerned. Wala kang magawa. Dito sa area ko sobrang congested ng globe reaching 1mbps download at 8pm. Even with parabolic antenna its only effect is increasing my upload speed, download speed is still at 1mbps.
Ang ginawa ko lang is nagswitch ako sa smart (pldt prepaid wifi sim lang naman since backup net lang namin). And sa smart merong noticeable improvement between mimo and parabolic. 6km from cell site with no line of sight. Below are the results:

Disclaimer: PLDT Prepaid Wifi sim gamit ko using Huawei B818 Modem. Natry ko na sa B525 kaso 2 bands lang kaya icombine ni B525 and dito sa area namin pwedeng magcombine ng Band 1 + 1 + 3 + 3 according sa cp ko hahahha. Speed may vary depending on your area, equipment, and time. Take this with a grain of salt and btw the speed will also vary on the cell site your connected to. If congested yung cell site try to locate another one.
