Description: When selecting a best fit solution for data communication it is important to consider the following factors that may impact the user’s operation of each telemetry solution. Factors include data availability, data reliability, cooperation and economy of scale, Initial Purchase Cost, Recurring fees, data distribution, latency, maintenance, security, and sustainability. Data Availability is impacted by the system design that ensures a certain degree of operational continuity over a given period. Disruptions of the data stream lead to data loss. These disruptions often occur during events of hydrological significance, thus interrupting data flow when it is most needed. Availability is usually measured as a percentage of time the system can be expected to operate over a given amount of time.High Availability solutions include: Satellite-based relay systems, such as Geostationary Satellite, where the relay is not contingent upon any event such as extreme weather.Lower Availability solutions include: GSM/GPRS where extreme weather can impact the mobile phone communications through outages or over use by the public
