*Towards a Wireless Broadband Revolution...*

*The most significant shift in communication since cellular networks*

## 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

## Vehicle Accident

**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

**WiMAX, LTE, MESH ****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**

## 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
