Overview
The Broadband Technology Opportunities Program will allocate billions of
grant dollars for broadband support for healthcare. WiMAX in healthcare
can be reduced to a discussion of the "3 A's": access, applications
and affordability. This simple methodology explains the advantages of WiMAX
in healthcare. In order to make universal healthcare coverage affordable,
the United States will have to make universal broadband a reality. Patients
or healthcare professionals attempting to transfer an X-ray from one office
to another are frequently reduced to copying the image to CD-ROM and hand
carrying or mailing the image to the distant office.
Impending regulations regarding electronic medical records (EMR) will further
underscore the need for universal broadband coverage. How will healthcare
professionals upload those EMRs if they don't have broadband connectivity
at the office or clinic? How will the healthcare professional review those
EMRs from home in the event of an emergency?

Key Benefits
- Assists grant writers in explaining broadband applications for the healthcare
industry such as connecting the broad movement to Electronic Medical Records
(EMR) in the US and the need for affordable broadband access for rural
hospitals, clinics and doctor's offices
- Provides grant writers with easy-to-understand explanations of mobile WiMAX in support of ambulance crews and other First Responders
- Enables grant writers to connect the breakthroughs in H.264 video compression
and telemedicine or telehealth for rural communities and healthcare providers
which could lead to savings in healthcare costs in the billions of dollars
annually
