Hi,

I dont think any one specific product from us ticks all the boxes that you want. I guess you can develop a product that uses some of products (nrf53,nrf52,nrf9160) to achieve something that maybe might be able to tick all the boxes. 

Happy Easter

thank you for your feedback

actually i want to produces a large quantities of my product, I want to guarantee my customers "0% of interference possibility", most of the users are living in same area, so I am asking  is there any product i can use to meet this requirement, forget about other requirements I have mentioned in first post

Hi

We don't have a product that will guarantee 0% interference. All radio devices are prone to interference from different types of factors like other radios, background noise and different environmental factors.

If you intend to have a network of devices communicating, sending voice live over a large area then a LAN might be ok to use if there is enough WIFI routers to cover the area and amount of devices that you want to connect. 

Sorry we cant be of more help

hello Jonathan

thanks for you help I appreciate it 

please another question "what the exact maximum transceiver using same channel or frequency can be exist in the same area without interference between them" please neglect the interference and noise comes from other manufacturers 's devices or surrounding environments noise.

 Do you mean number of transceiver that can use on channel. There is not a easy single correct here i think. 

Check out the response in these two posts:

 https://devzone.nordicsemi.com/f/nordic-q-a/46237/max-of-ble-devices-simultaneously-detected-by-a-smartphone-in-central-mode 

It gives you an idea of how it works with BLE at least. There will be other approaches that might yield other results with different radio technology.
