Remote Telemetry in Rural Areas Using TV White Spaces - State of the Art

Various technologies for remote telemetry systems in rural areas has been used in the past. The use of television white spaces (TVWS) is promising to reduce the cost and complexity of future remote telemetry systems. In this paper, the most important concepts involving the technology of wireless communications and networking suitable to support remote telemetry in rural areas are briefly reviewed with emphasis on the available hardware platforms for its implementation. The paper also summarizes the main international standards on the use of TVWS and issues related to the coexistence of networks sharing the same frequency bands. The paper concludes with a discussion on the main communication and network requirements of remote telemetry systems for rural areas.
