E911 has several limitations that can impact the accuracy and effectiveness of emergency response. Here are some of the main limitations:
- Limited location information: E911 relies on location information from cellular or landline networks, which may not always provide accurate or precise location data, especially in areas with poor signal coverage. This can result in emergency responders being sent to the wrong location or experiencing delays in reaching the correct location.
- Inability to handle multimedia data: E911 is primarily a voice-centric system and does not support the transmission of multimedia data such as photos or videos, which can provide valuable additional information to emergency responders.
- Limited ability to coordinate with other emergency response systems: E911 systems are often isolated from other emergency response systems such as computer-aided dispatch (CAD) and public safety answering points (PSAPs), which can limit the ability of emergency responders to coordinate and share information.
- Inability to handle non-voice communications: E911 systems are designed primarily to handle voice communications and may not be able to handle other types of communication such as text messages or video calls, which can be important in emergency situations.
- Limited support for new technologies: E911 is an older system and may not be able to support newer technologies such as IP-based communication systems, which can limit the ability of emergency responders to take advantage of these technologies to improve emergency response.
NG911, on the other hand, is a more advanced system that is designed to integrate a wider range of communication technologies and data types. NG911 systems are IP-based and use a variety of data sources, including sensors, GPS, and multimedia messages, to provide more accurate location information and enable more efficient emergency response. The move to NG911 aims to address many of the E911.
