Broadcast Implications for 3G Cellular Phase Out in the US:
Mobile network carriers in the US are shutting down their 3G networks, which rely on older technology, to make room for more advanced network services, including 5G. On February 22nd 2022, AT&T completed the shut down of the 3G network and in coming months Sprint, T-Mobile and Verizon will also be closing down old network infrastructure.
The FCC has provided an update and guidance about the 3G cellular phase out and service shutdowns, which is available at https://www.fcc.gov/sites/default/files/plan_ahead_for_3g_shutoff_consumer_guide.pdf
What Do I Need to Do to Maintain Reliable Broadcasts?
To ensure you maintain reliable broadcasts over cellular connections:
- If you haven’t already, move away from 3G cellular data cards and 3G MiFi hotspots for remote broadcasts.
- Customers using AT&T cellular with their ViA remote codecs should ensure they upgrade to the latest ViA firmware (v2.20.48 or higher) to avoid any connectivity issues due to AT&T network upgrades occurring in February 2022. Access the latest firmware at https://tieline.com/via-support-page/
- Ensure you regularly update your ViA codec firmware in coming months to stay ahead of any network upgrades.
The FCC has provided the following information relating to the phasing out of 3G services.
When is it happening?
As early as January 1, 2022, though plans and timing to phase out 3G services will vary by company and may change. Consult your mobile provider’s website for the most up-to-date information.
- AT&T announced that it will finish shutting down its 3G network by February 2022.
- Verizon announced that will finish shutting down its 3G network by December 31, 2022.
- T-Mobile announced that it will finish shutting down Sprint’s 3G CDMA network by March 31, 2022 and Sprint’s 4G LTE network by June 30, 2022. It also announced it will shut down T-Mobile’s 3G UMTS network by July 1, 2022, but has not yet announced a shutdown date for its 2G network.
If your mobile carrier is not listed here, you may still be affected. Many carriers, such as Cricket, Boost, Straight Talk, and several Lifeline mobile service providers, utilize AT&T’s, Verizon’s, and T-Mobile’s networks.
Note: These are dates for completing the shutdowns. Carriers may begin retiring parts of their networks sooner.
