3 >CTIA sponsored industry conference calls to discuss industry responses to the Congressional and FCC activities. >The CTIA initial proposal calls for use of SMS as the short term EAS technology with a view of later adoption of a better technology. Recognizing the shortcomings of SMS as an EAS technology, the industry proposes that six predicates be met: 1. The system must be [voluntary for carriers and] opt-in to a specified zip code for consumers as with Wireless AMBER Alerts. 2. This service should be limited to only transmit Presidential or Governor-level messages. 3. Government must deliver messages to a single point of aggregation, like the wireless AMBER Alert. 4. Limitation of liability for participating carriers is necessary. 5. Support cost recovery mechanisms and government support for new deployments. 6. Government must deliver emergency alert messages in a format that can be retransmitted using the SMS protocol. >CTIA and the industry held their first meeting on May 4, 2006 with key government officials in attempt to define the service requirements for a longer term wireless emergency alert service.
