The use of spread spectrum has increased over the years due to deregulation, and it is used in a wide array of telecommunications and communication fields. It was first used in the military in the 1950s for secure communications, and usage spread in the early 1980s for use in many satellit...
Chirp spread spectrum (CSS) is based on a spread spectrum system of the method, which makes use of modulated chirp pulses of wideband linear frequency and its complete assigned bandwidth to put out and transmit a signal for the reason that the chirps make use of a broadband of the spectrum...
What is it? The Chirp, or Chirp Spread Spectrum (CSS), denotes long-range radio frequency technology designed for wireless communication. It is used to identify and monitor indoor and outdoor locations of people and assets. How does it work? This technology is employed to transfer data between...
A short burst of data is transmitted on the current narrowband channel, and then the transmitter and receiver tune to the nextfrequencyin the sequence for the next burst of data. In most systems, the transmitter will hop to a new frequency more than twice per second. Because no channel is ...

GSM is the international standard for mobile communication. It enables users to transmit data, make phone calls and exchange text messages seamlessly. GSM operates within a framework of radio channels and cellular technology, allowing multiple users to access the same bandwidth simultaneously. In Europe...
Steganography is the art of hiding secret messages in plain sight. Learn about steganography types, techniques, applications, examples, and more.
Object detection model is an intermediary between the system and the image. It assists with the multi-class categorization of objects between different data classes known to the model. Object detection helps determine the essence of an entity in any shape or form: straight, crooked, occluded, et...
Rachel’s experiencegoing from getting a PhD in statistics to working at Google is a great example to illustrate why we thought, in spite of the aforementioned reasons to be dubious, there might be some meat in the data science sandwich. In her words: ...
CDMA employs analog-to-digital conversion (ADC) in combination with spread spectrum technology. Audio input is first digitized into binary elements. The frequency of the transmitted signal is then made to vary according to a defined pattern code. This enables the signal to be intercepted only by...
