Timing: The Backbone of a 5G Network
Reliable Synchronization Beyond GNSS Limits
Wireless carriers rely on timing, but synchronization is complex. Equipment like 5G Radio Access Network (RAN) nodes need to be located indoors where Global Navigation Satellite Systems (GNSS) like GPS and Galileo can’t reach without an outdoor antenna. Failed installations and repeat technician visits can delay network deployments.
Meanwhile, standalone precision time protocol (PTP) systems often fall short of the accuracy 5G requires, especially when time-division duplexing (TDD) is deployed.
A resilient, secure, and proven solution to complement GNSS is available now: Iridium® PNT.
Why Carriers Can’t Rely on GNSS for Timing Synchronization
- Unreliable signals: Multipath errors and GPS failures, even with outdoor antennas.
- Deployment delays: 5G rollouts slowed by permissions and scheduling conflicts.
- GPS bouncing: Repeat alarms and multiple truck rolls result.
- Roof rights battles: Endless landlord negotiations and steep fees.
- Costly installations: Drilling through multiple floors to run antenna cabling.
Iridium PNT Makes Time Synchronization Simple
Easily connected and quickly configured, Iridium PNT works with a small indoor antenna—even in challenging environments.
Installations succeed the first time, saving money while delivering precise synchronization where GNSS can’t reach. Iridium PNT-capable receivers being implemented at 4G and 5G RAN sites help wireless carriers meet 3GPP requirements.
Iridium PNT Offers 5G Networks:
- Reliable timing: A Stratum 0 UTC source of time, Iridium PNT can help create a Stratum 1 timing clock compliant with the ITU-T G.8272 PRTC-A performance standard. It’s ideal for the precision timing that carriers demand.
- Indoor coverage: With a small indoor antenna, Iridium PNT provides precise synchronization when distributed PTP falls short, and GNSS isn’t available. It’s perfect for sites where outdoor antennas are impractical or prohibited.
- Resilience: Iridium PNT serves as an essential contingency or backup to protect PNT-dependent systems, providing a highly reliable timing source.
Synchronizing 5G Anywhere, Anytime
We partner with leading manufacturers to deliver a portfolio of PNT-enabled products. Multi-feature receivers connect directly to RAN gear or routers, providing reliable timing synchronization wherever and whenever GNSS isn’t available.
With a range of capabilities, performance levels, and price points, Iridium PNT solutions overcome 5G’s toughest challenges and meet carriers’ most critical needs.
