12. What we noticed
12
» AML/ELS helps to improve/quicken response;
» Location SMSs are received fast enough to timely
complement response procedures;
» GNSS-based locations are most precise, accurate and
reliable;
» “No location” marked SMSs may contain valid
location coordinates;
» Certain parameters may be missing in AML/ELS
string;
» Wi-Fi-based locations should be taken more carefully;
» Investigate SMS delivery delays/failures with MNOs
to make it even more reliable.

13. Recommendations for AML/ELS
13
» GO FOR IT!
» Meet MNOs in your country;
» Meet other PSAPs in your country;
» Contact Google (Specs, Thunderbird);
» Choose location delivery transport (SMS, HTTPS
POST or both);
» Setup SMS connections into „Transceiver“ mode;
» Make notifications to call takers of handset
location received;
» Train call takers and dispatchers.

14. Thank You All!
AML/ELS will trace you down to mushroom...
Which we‘re happy with 
