Next Generation Emergency Next Generation Emergency Services – Market DriversServices – Market Drivers

• Emergency service requests (9-1-1 calls)– New methods of requesting emergency assistance

(e.g. VoIP, SMS, Call Relay Centers, E-mail, etc.)– Enhanced capabilities of consumer devices

(e.g. display phones, text messaging, mobility, video)

• Technology modernization– Existing aging infrastructure– Easier integration of new technologies– Enhanced communication capabilities

• Interoperability between service providing agencies

• Enhance service response capabilities– Information access and advanced services
