ABSTRACT
This paper presents setup and results of a long-term outdoor range experiment carried out in a real environment. The objective was to explore long-range wireless communication in sub-GHz license-free radio bands, i.e., 169, 433, and 868 MHz under more realistic conditions. Not only transmission range, but also packet loss and received signal strength were evaluated. A large set of radio configurations was used to study the impact of transmission power, bit rate, and packet size. Also, the relationship between packet loss and received signal strength was investigated. A model could be developed that can help determine the expected packet loss rates as a function of the radio configurations and measured RSSI values.

Adaptive range-based localization algorithm based on trilateration and reference node selection for outdoor wireless sensor networks
AbstractLocating the nodes of outdoor wireless sensor networks (WSNs) using (tri)lateration with a low-cost ranging technique, such as the received signal strength indicator (RSSI), often results in inaccurate location estimates. This can ...
Indoor Corridor Wideband Radio Propagation Measurements and Channel Models for 5G Millimeter Wave Wireless Communications at 19 GHz, 28 GHz, and 38 GHz Bands
This paper presents millimeter wave mmWave measurements in an indoor environment. The high demands for the future applications in the 5G system require more capacity. In the microwave band below 6 GHz, most of the available bands are occupied; hence, ...
Designing energy efficient automatic repeat request protocol in wireless sensor networks
CHANTS '09: Proceedings of the 4th ACM workshop on Challenged networksEnergy constrained Wireless Sensor Networks (WSNs) challenge traditional protocols in many aspects. One such challenge is the requirement of energy efficiency in the Automatic Repeat Request (ARQ) protocols. Although traditional ARQ protocols are ...
