This is my place represented as a 5 years old kid drawing:
Distance between home and each tower is between 2 and 3 km.
I've tested on my roof with a smartphone and I can get 20-30 Mbps download and 10-15 Mbps upload with ~50 ms ping, it would be plenty enough for me.
There are 2 4G towers "near" me, they're obstructed but as reported the results are good enough with the 3 dBi (I suppose) antenna of phone.
I want to put an LTE modem under roof with 2 external antennas for Carrier Aggregation.
Here are the questions:
- Can I do Carrier Aggregation on both two towers at the same time? Or is it possible only for different bands on the same tower?
- Do I need 2x2 or 4x4 MIMO? For what I've understood with 2x2 MIMO I can hook both the two towers at the same time, but contemporary transmission/reception wouldn't be optimal unless I'll use 4X4 MIMO. Bullshit?
- Which setup should I go with? (I know you'll probably laugh at "high gain 20 dBi")
- 2 high gain highly directional antennas (~20 dBi/25°)
- 2 medium gain medium directional antennas (~10 dBi/60°)
- a mix high/medium gain highly/medium directional antennas (~20 dBi/25° + ~10 dBi/60°)
- How can I investigate without special equipment how I should point my antenna/antennas?
So far I've investigated using my smartphone with Network Cell Info Lite: https://play.google.com/store/apps/deta ... lite&hl=en
Is there some special trick to investigate signal direction, like putting my smartphone in a metal tube/pipe and turn it around on a tripod to find the best signal directions?
- Is MIMO only possible with LTE Cat 6? Can I MIMO on LTE Cat 4?
- Is it possible to build manually LTE antennas to save money?
