Cayman with D3O® 5G Signal Plus

Integrated with D3O with 5G Signal Plus Technology

The first 5G compatible smartphone protection material

Due to the high sensitivity of 5G, today’s 4G smartphone cases can significantly impact the performance of 5G antennas, causing dropped calls, slow data transmission, and poor battery life with the device needing to work harder in order to find and maintain a good connection. Thinner cases made with low permittivity materials, such as D3O with 5G Signal Plus Technology, allow for stronger signal to pass through the case.

How D3O® with 5G Signal Plus Technology™ Works

D3O with 5G Signal Plus Technolog is a low-permittivity material with micro voids that allows the 5G signal to pass through to the device, which has been proven to reduce 5G signal loss by up to 37 per cent compared to other protective case materials in market.
