In view of that, the current ACE 8150P WCDMA 3G DTU used in our Wireless Noise Monitoring System need to be replaced to ACE510-71F 4G DTU.
What does this mean for you?
With the upcoming retirement of 3G services, the current 3G modem used at the site will no longer be compatible with the network after 31 July 2024. We encourage
you to upgrade to 4G-enabled devices to continue using the current Wireless Noise Monitoring System.
How does this affect your services?
Once 3G services are retired, you may experience disruptions in voice and data services on the existing 3G modem. To ensure uninterrupted connectivity, kindly
switch to a 4G-capable modem before the specified date.
