Long Range (LoRa) Transmission Through Ice: Preliminary Results

2021 IEEE International Instrumentation and Measurement Technology Conference (I2MTC), 2021
Long Range (LoRa) has rapidly become one of the most widespread transmission technologies for the development of distributed monitoring systems for a wide range of applications within the Internet of Things (IoT) framework. Indeed, thanks to its robustness and high performances in terms of low power consumption and long transmission range, it has been ...

Long-Range CW Sound Transmission

The Journal of the Acoustical Society of America, 1961
An attempt was made to propagate pulsed CW sound coherently over thousand-mile distances in the mid-Atlantic using the focusing properties of the sound channel. The sound field emanating from a 440-cps lumped source at the sound channel depth off Barbados was studied at stations 159 and 975 mi. away in the NNE direction.

Battery-free short-range self-powered wireless sensor network (SS-WSN) using TENG based direct sensory transmission (TDST) mechanism

, 2020
Wireless Sensor Networks (WSNs) bring the basis that the development of the Internet of Things (IoTs) relies on. However, external power requirement restricts the widespread applications of WSNs.

Restricted-Range Sky-Wave Transmission

Proceedings of the IRE, 1948
This paper reports results of a study showing that it should be feasible to restrict considerably the range within which radio signals may be received after reflection from the E layer of the ionosphere. This is accomplished by proper choice of operating frequency and by using a relatively simple directive array beamed vertically upwards.

Characteristics of Multiple Range Hydromechanical Transmissions

SAE Technical Paper Series, 1972
<div class="htmlview paragraph">The purpose of this paper is to show the advantages of multirange hydromechanical transmissions and to show some basic relationships of primary design parameters. Hydromechanical transmissions can be designed so that they maintain a high efficiency over a wide range of torque/speed variations.

Scintillations in long-range acoustic transmissions

The Journal of the Acoustical Society of America, 2001
In the Acoustic Thermometry of Ocean Climate (ATOC) program’s Acoustic Engineering Test (AET), broadband 75-Hz center frequency transmissions were recorded on a 700-m-long vertical array, 3252 km distant. Previously reported results from the AET using 12.7-min. averaged data by Colosi et al. [J. Acoust. Soc. Am.
