PBCC method
PBCC method • PBCC is one of the data encoding methods that allows you to increase the data transfer rate by compressing the code.
OFDM method.
OFDM method. • OFDM is one of the methods of digital signal modulation that allows increasing the data transfer rate due to the reasonable use of communication channels and data transmission method. The main reason for the appearance and application of this signal processing method is the search for ways to combat broadband interference – the main reason for poor communication in conditions of a
The FHSS method.
The FHSS method. • FHSS is another method of signal processing in order to expand its spectrum, used in wireless local area networks.
The DSSS method.
The DSSS method. • DSSS (Direct Sequence Spread Spectrum) is one of the main signal modulation methods used in wireless local area networks.
What is multiplexing?
What is multiplexing? Due to the fact that computer networks are used to transmit data over long distances, they tend to minimize the number of wires in the cable, in order to save money. Therefore, technologies have been developed that allow several data streams to be transmitted over the same communication channel at once
Mesh networks.
Mesh networks. • Mesh network is a distributed, peer—to-peer, mesh network.
What is MQTT?
What is MQTT? • MQTT or Message Queue Telemetry Transport is a lightweight, compact and open data exchange protocol designed to transfer data to remote locations where a small code size is required and there are channel bandwidth limitations. The above advantages allow it to be used in M2M (Machine-Machine Interaction) and IIoT (Industrial Internet of Things) systems.
What is IoT?
What is IoT? • The Internet of Things (IoT) is a set of physical objects connected to the Internet and exchanging data. The IoT concept can significantly improve many areas of our lives and help us create a more convenient, smart and secure world.
Thread technology.
Thread technology. • Thread is an open protocol of a local wireless network with a mesh topology, created specifically for communication of IoT devices.
Differences between the router and the switch.
Differences between the router and the switch. • The switch communicates between devices of only one network, while the router can connect multiple networks
What is a router?
What is a router? • This device is designed to connect multiple networks of different architectures. This means that the router is able to connect your personal home network to the Internet
Z-Wave technology.
Z-Wave technology. • Z-Wave is a wireless communication method that uses low—power radio waves that are safe for health. Installing a smart home powered by Z-Wave technology is extremely simple: there is no need to lay cables and wires, repair and interfere with the interior. The signal is perfectly transmitted through walls, floors and furniture.
What is a switchboard?
What is a switchboard? • A switch is a device that connects several nodes of the same computer network. Such nodes can be both computers themselves and other devices: printers, servers, and so on.
ZigBee technology.
ZigBee technology. • ZigBee is a technology for building wireless data transmission networks. The ZigBee network operates in the license-free 2.4GHz band and is focused on transmitting small amounts of information from a variety of sources, including battery-powered ones.
Packet switching
Packet switching • Packet switching is a special way of switching network nodes, which was specially created for the best transmission of computer traffic
