My client has 3 buildings with apartments for rent. The buildings are located far from wired internet providers.
LTE signal is not perfect (in good weather we can reach 30MBps downlink and about 5-8MBps uplink from single LTE connection). LTE routers connect to 3 diffrent operators.
So far I have built 3 independent networks like this:
Now I want to connect them into one network and handle problems like problems with one LTE operator, dead SXT LTE device (so far we had 2 failures) etc.
My idea looks like this:
Question 1: Is this good idea?
Question 2: What kind of router should I buy?
Can I use something like RB750r2 and add some low cost switch (I need 6 etherent ports), or should I get something like RB2011? There may be about 30-40 people using internet in these buildings.
