That said, they <br>may be thinking more along the lines of short, burst messages (text, <br>sms) instead of continuous data flow. Reading some of the articles <br>circulating about the communication issues from Hurricane Sandy, it <br>sounds like text/sms was available when voice wasn't. <br><br>This does highlight the rationale for a diversity of telemetry paths. <br>For example, UUSS uses cell modems, spread-spectrum radio (900MHz and <br>2.4GHz), DSL and other network connections from the site hosts (e.g., <br>microwave, T-1, etc). We also still maintain our network of <br>short-period stations on FM VHF radios. This diversity has helped out <br>during non-disaster outages; e.g., a site host replaces a firewall and <br>knocks out telemetry but a nearby station on spread-spectrum radio still <br>provides data for that region.<br><br><br>--jon<br>-- <br>===================================<br>Jon Rusho<br>Seismic Network Engineer<br>University of Utah Seismograph Stations<br><br>jon@seis.utah.edu<br>801-585-5523<br><br><br>Greg Steiner wrote:<br><blockquote type="cite">I am curious as to what the cellular providers are saying about <br></blockquote><blockquote type="cite">availability of their networks after a natural disaster.
