I recently replaced my Netgear Nighthawk R7000 + 3 extender system with a 2.5 GHz mesh system with 3 satellites. I instantly saw a massive improvement in coverage in all corners of my home. Areas which previously received less than 10 mbps signal, now consistently receive 50-100 mbps network connection. I can now stream Netflix almost anywhere in the house, and no longer see any performance issues connecting to MSTeams or Skype. A base station and 3 satellites is sufficient to cover a large (10,000 ft2) tri-level townhouse and garden and connect to tens of devices without any significant problems. Not a cheap system, but excellent value for money if you need fast connectivity throughout a large home.
