WiMax Earthquake Monitoring System Enhanced real-time inflow of data
pre & post Avoid phone system saturation from
telephone traffic load as people call in/out after the earthquake.
Real-time data is especially important at this window of time as the aftershocks will strike.
Real-time data will give the precious seconds needed for relay communications

Existing
The CISN consists of several different types of seismic instrumentation
The CISN uses different types of sensors (short-period, broadband, and strong-motion)
In different environments (surface and/or free field, structures, boreholes)
With different recording and communications systems, some without communications.

Value
WiMax technology will resolve a mission critical domain problem that arises from using PC based platforms as the buffering and structuring of data in a file system, latency, feedback on traditional systems.
WiMax technology will enable WAN data communications – connect the unconnected, more nodes on the network
