Wireless remote data
Technologies and sample systems that gather sensor data across distances, usually via radio links. This includes general telemetry and SCADA (supervisory control and data acquisition), especially for gathering data about wildlife, natural resources, and distributed energy systems.

VSAT services finding new customers: 2002 summary of changes in satellite IP markets:

  • 90% of new customers request IP support
  • "By supporting IP and standardizing certain parts of the technology, [service providers] can deploy two-way VSAT networks with [customer-premises equipment] that costs $500 to $600," Baugh says. He says this would be the floor of the market with users paying about $70 to $200 per month, per site for service for perhaps 128K bit/sec worth of bandwidth.
  • Gilat's Spacenet Connexstar costs $119 per month for 128K bit/sec upstream and 500K bit/sec downstream with a one-time equipment cost of $1,000.
  • Hughes is the leading provider of VSAT services in North America with Directway. Starband and Tacyon also sell VSAT Internet access services to individual users. These offerings [appeal to new customers "such as real estate agencies and veterinarian offices"
  • In the past, most VSAT service providers were interested only in deployments that reached thousands of sites, but there has been a change of philosophy within many providers. Traditional VSAT networks are built based on the amount of bandwidth a company needs and the number of sites that will share that bandwidth.  Classic app: reduce the time credit for card authorization, eg "from 15 sec down to 3 sec... A group of 500 stores could share a 128K bit/sec satellite channel and not experience any delays because of the small amount of traffic that's being sent over the network, even though it's regularly used."  Price: for 4000 stations, perhaps $60/mo/station, for hundreds of sites, perhaps $100/mo/station.
