While modern wireless technologies have made remote monitoring more accessible, the engineering behind reliable long‑range ...

Fifteen miles above you, a small styrofoam box is shrieking into the void. Its voice is binary—relentlessly transmitting temperature, pressure, and wind speed from the freezing stratosphere. In two ...

Abstract: In this paper, we introduce a novel OFDM-aided multifunctional multiple-input multiple-output scheme based on multi-set space-time shift keying (MS-STSK), where the information transmitted ...

Abstract: The performance of frequency-hopping systems with multiple frequency-shift keying and hard decisions is determined for operation against optimal partial-band jamming. A receiver that ...

This library very simply generates a set of channel symbols for JT65, JT9, JT4, FT8, or WSPR based on the user providing a properly formatted Type 6 message for JT65, JT9, or JT4 (which is 13 valid ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Encode and decode messages using sound waves. Support for multiple transmission protocols. Optional real-time audio transmission and reception via PyAudio. GGWave transmits data using frequency-shift ...

Late last month, researchers revealed a finding that’s likely to shock some people and confirm the low expectations of others: Renewable energy facilities throughout Central Europe use unencrypted ...

No audio available for this content. GLONASS satellites traditionally use L1 and L2 frequency division multiple access (FDMA) signals. FDMA is characterized by a different transmit frequency for each ...

Amazon released this estimated coverage map Tuesday for its Sidewalk wireless network. Amazon says its Sidewalk community wireless network, formed by pooling internet bandwidth from users of Amazon ...
