Agenda

• What’s Important for Emergency Medical Services?• Wide-Area Wireless Technologies• Spectrum• Example: LTE for 700 MHz Public Safety• Example: WiMAX for 2.5 and 3.5 GHz • 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

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

Mobile broadband is getting faster, but a lack of ubiquitous coverage hampers mobile internet….multiple network access is required

Enabling 3G-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

• Networks:– LTE (E-UTRAN)– WiMAX (802.16e – 802.16m)– UMB– WiFi– Flash OFDM
