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...
Governments regulate the broadcast spectrum and often dictate some aspects of spread-spectrum communications. For example, in North America, the industrial, scientific and medical waveband is divided into 75 hopping channels, and the devices using them may not transmit with more than 1wattof power ...
Ethernet switching involves many complex terms and processes. Let’s break these concepts down one by one: Packet switchingis a networking technology that switches use to forward data frames through a network based on their destination address, rather than using a dedicated circuit for each communica...

For instance, if you search for international flights from the USA to Bolivia, chances are the airfare will be higher because of your IP address. You might be able to source cheaper travel and hotels by switching your IP location via the VPN to either the country where the airline is headq...
Asynchronous Transfer Mode (ATM) is a switching network architecture that uses 53-octet cells to transport data. It can be used in LANs and has been recognized for its capacity to handle multimedia traffic. ATM LAN emulation enables the development of VLANs over an ATM backbone. ...
Frequency Hopping Code Division Multiple Access (FH-CDMA) is a basic modulation technique used in spread spectrum signal transmission. FH-CDMA is the repetitive switching of frequency at the time of radio transmission. Advertisements This helps to reduce the strength of electronic warfare, that is,...
LoRa1121 is a communication module developed by NiceRF, based on the Semtech LR1121 chip. It offers multi-band LoRa and long-range frequency hopping spread spectrum (LR-FHSS) communication, supporting connections below 1 GHz, 2.4GHz, and ISM bands. The module supports various modulation methods ...
Basically, the stable part of the spectrum can’t handle the bandwidth 5G needs, but the super fast part of the spectrum isn’t reliable enough to fly solo. Enter adaptive beam switching: fancy tech speak for “Your phone is constantly scanning for interference. It jumps...
In the event of a deep fade, caused by destructive interference, no signal power is seen at the receiver, and so communication fails. Multipath fading can be overcome byshifting the location of one node, or by switching the communication carrier frequency. ...
