Yes, on a device level, the device has to do that if it is going to be called a 'phone'. There are lots of laptops and tablets that are connected computing devices that do not do that. As far as I know, the Pyra is shipping as a connected computing device. I.e. not a phone.I dunno, if it has that functionality advertised and you initiate a call to the emergency services, as I understand the legislation (that is not at all really) it should recognise what you're doing and send the location data. The only question in my mind is whether we have any control over what data source it uses; the rules say it can use triangulation data, or timed deltas from two or more stations (?) or full GPS coordinates, or another method I don't understand at all I think. Maybe if we haven't turned on the GPS and it doesn't have a satellite lock, it'll fall back to the older methods I dunno.
But, even within the phone, there are several layers of interaction that have to be handled in software.
* First, phone to user. User has to initiate the call. Which requires phone dialer software (or brute force AT commands).
* Phone to/from tower(s). Phone has to communicate to a mobile phone tower, which requires software to manage tower/frequency switching. The software on the phone keeps track of what towers are in range. The software on the tower keeps track of what phones are in range.
* Phone from GPS satellite(s). Phone gets GPS signal from 2 or more satellites, interprets those in software to generate it's location.
The E911 system is, to my knowledge, a piece of code on the phone that can be activated from the tower to force the phone to reply with all of it's positional information gathered from the above software's outputs. The Pyra doesn't have that software stack.
However, on the page:
Just having a chip that can contact a mobile phone tower doesn't make the device a 'phone' though. Just having the ability to force an ADTD command through the device does not make it a compliant 'phone'. There is a software stack that would need to be developed.The mobile edition adds mobile internet, and also has telephony services (making the Pyra a phone), it also adds GPS, a 6-axis digital compass, a pressure-, humidity- and gas -sensor.
