Summary


WiMAX, LTE, MESH

Wireless Network

Vehicle Accident

Doctors at the emergency room can see the vehicle
and get an understanding of the mechanism of injury
to guide their treatment of the victim.

Portable or fixed mounted cameras can be used to
capture video or still images of a vehicle accident
to send to emergency room doctors.



Video increases emergency room doctor’s knowledge of the
mechanism of injury, enabling quicker and possibly more accurate
treatment



Biometry data from Incident Scenes enable real time monitoring of
Patients on the way to the Hospitals

Wireless Network

Remote Medical Diagnosis

Doctors at the emergency room can help guide
treatment of the victim, especially important for time
critical treatment.

Cameras inside ambulances can capture
video of patients to send to emergency room
doctors for consultation.



Remote diagnosis can shorten the time before treatment which can
potentially save lives and shorten recovery time

4G Speeds: OFDMA


Orthogonal Frequency Division Multiple Access (OFDMA)


Is a digital modulation technology, like CDMA,


Uses a large number of orthogonal (non
-
interfering) overlapping sub
-
carriers that are assigned to different users, leading to:


Improved spectral efficiency (throughput per Spectrum used)


Better performance under non
-
line
-
of
-
sight, multipath interference, or faded
conditions
