Hi Support Team

We want to implement 4 people voice communication in a network like picture below. Do you have any solution for this. Many thanks.

Hi,

Thanks for checking with us. Mobile phones can basically satisfy the picture shown if you do not have other requirements.

Could you provide more information about this application? Like environment (Indoor/outdoor), expected communication technologies(Wi-Fi, BLE mesh, Thread, DECT NR+), voice quality, price and any other details.

Best regards,

Charlie

Hi

Or could you provide us the solutions can satisfy this and introduce the advantages of each solution? Then let us choice which is the most suitable for us. Many thanks.

Hi,

We do not have such application level solution direclty.

Considering the communiation requirements(mulit devices communication and several kiloetters distance), DECT NR+ mesh network could be a good choice, but 1.9GHz is not avaliable including some regions like China at current monment (DECT NR+: A technical dive into non-cellular 5G - Blogs - Nordic Blog - Nordic DevZone). Thread may be possible, but this need to be verified with testing at real condition.

We have a solution partener Lynq which has solution for DECT NR+ based mesh voice network based on nRF91x1 chips. You may reach them from DECT NR+ Products - nordicsemi.com.

Best regards,
