Hi Mimosa Team,
Very excited to get your PtMP products out in the field for testing.
A question we have regarding the A5-360s:
Our understanding when the A5-360 broadcasts and uses the benefit of mu-mimo, the A5-360 decides which quadrant to use when communicating with cpes based on spacial location. We are assuming with the above in mind an operator can scale a mimosa PtMP network easily and cost effectively by deploying a A5-360 first and then adding A5-90s to which ever quadrant is most dense first as needed until you have 4 A5-90s in the air essentially allowing you to retire the A5-360 for future expansion. Is that a correct way of thinking or will we experience a problem trying to scale this way? This also assumes the operator is using correct sync planning with the A5-90s and A5-360
The only problem I can for see with that approach is if the A5-360 still broadcasts on quadrants that have no clients on it. The clients connected to the A5-90 would hear the A5-360 as noise if they were gps sync’d which would be very problematic. If the quadrant of the A5-360 that the A5-90 is now covering doesn’t broadcast when it has no clients connected to it then I would imagine this would work. Maybe a Mimosan can clarify. If that is not how the A5-360 operates now, is there a way to implement it? It would be a huge Mimosa specific benefit to operators.
Imagine another manufacturers setup and scalability:
1- You start with an Omni to get your POP started
2- Load up the omni with clients
3- replace omni when overloaded with at least 3 120deg sectors all in one go. You cant sync the omni with any sectors since clients connected to the sectors would hear the omni as noise. You either need to replace the omni with 3 sectors all in one go or hope you have spectrum to run 3 sectors and an omni unsynced. And dont forget guard channels. If you replaced the omni you would go from theoretically Y amount of clients supplied by the omni to Y * 3. Thats a large amount of capacity to add and a large expense all in one go.
Let me know your thoughts guys and thanks for listening!
Note- I posted this also in the A5 General Discussion 2 weeks ago and no response so I figured I should make my own topic
