NG911 networks replace which type of networks?

NG911 networks replace which type of networks?

• A. Broadband internet for general use
• B. Narrowband circuit-switched 911 networks that carry only voice and limited data
• C. Cellular networks only
• D. Satellite communication networks

Answer: (B)

NG911 is an IP-based, packet-switched 9-1-1 system that replaces the old narrowband, circuit-switched 9-1-1 networks. Those legacy networks were designed primarily for voice and carried only limited data, using dedicated circuit paths that aren’t suited to multimedia or large data flows. NG911 moves to broadband, Internet Protocol transport, enabling not just voice but text, images, video, and richer data to reach Public Safety Answering Points more efficiently. It also improves data and location capabilities and interconnectivity with other emergency services. So the networks being replaced are the narrowband circuit-switched 9-1-1 networks that carried only voice and limited data.
