Multiple ESP32 Arduino comunication -- 2

I need to comunicate up to 32 nodes (esp32) to a single station / root (Esp32, Rasp what ever you recommed me)

- Expected range: ~150 meters

- I have preference to use esp32 features (esp now - esp mesh)

- Lora or 433/868Mhz is discarded due Duty Cycle

- Root will broadcast a 2Kb message every second

- Nodes will send 200bytes message to root every minute or less (need ACK, message must to be recieved)

- Nodes will be in movement most of the time, 0-60km/h and will exit coverage area at some point

- There is no control about when nodes talk to station, there is a chance that even all nodes talk in the very exact moment

- Nodes has size and power restrictions, small as possible and powered by battery

- Root has NOT size and power restriction

At the moment I only need advice on the hardware (no codding) and I am looking for someone with real experience on the solution, I do not accept people who talk about theory / paper specs witouth previus field testing

Hello, ESP32 works on BLE or WiFi, and none of it will be able to cover up to 150 meters, they can barely do you good up to 50 meters and in open space the best hope is HC-10 ( BLE as well but works on 433 MHz instead Lagi
