DescriptionWith the increasing popularity of smartphones, there is a growing demand for wireless networks. A city decided to cover the public places in the city wireless network. Suppose the layout of the city is a grid of strictly parallel 129 things to the streets and 129 north-south streets, and the distance between adjacent parallel streets is a constant value of 1. Things to the street from north to south, sequentially numbered 0,1,2 ... 128, north-south Street from west to east, sequential

, and then connect this broadband line to the wireless transmitter AP, and then on the computer need to install a USB port or PCMCIA wireless network card. The following is to set up a wireless network node, the role of wireless network node is the cable network signal into the wireless signal, its location determines the entire wireless network signal strength and transmission rate, positioning is very important. First, the wireless AP and LAN comp

Ethernet ports have three types of links: Access, Hybrid, and trunk: The connection terminals of these three types of links are different: Access type ports can only belong to 1 VLANs and are typically used to connect to a computer's port; The trunk type port allows multiple VLANs to be passed and can receive and send packets of multiple VLANs, typically used for connecting ports between switches; The hybrid type port allows multiple VLANs to be passed, can receive and send packets of multip

Of course, the HDFs client and the Datanode node receive blocks differently, but this article will focus on the data b

The I²c bus is designed by NXP (formerly Philips) and has a very concise physical layer definition with the following characteristics: As long as the two bus line: A serial data line SDA, a serial clock line SCL; Each device connected to the bus can have a unique address and a simple host From the system software to set the address, the host can act as a host transmitter or host receiver; it is a true multi-host bus, and if two or more hosts are initi

interval, and the following image shows the PT2262 encoding diagram: As shown above, each signal sent by the transmitter will carry a multi-uncorrupted set code loadline, each encoding loadline value is the same, the binary value is 0b010101010101010100001100, the corresponding hexadecimal code value is: 0x55550c. As can be seen from the graph, the period of the transmission code is equal, but the pulse width is different (the ratio of wide pulse to

multi-master bus, so any device can operate like a master controller and control the bus. Each device on the bus has a unique address that can work as a transmitter or receiver, depending on the device's own capabilities. A multi-channel microcontroller can coexist on the same i²c bus.I-party C bus:The main advantage of the I²C bus is its simplicity and effectiveness.Because the interface is directly above the component, the I²c bus occupies very lit

I²C transmits data between devices connected to the bus using only two lines (SDA and SCL). Each device is identified by a unique address (whether it is a microprocessor, LCD driver, memory, or keyboard interface) and can be used as a transmitter or receiver depending on the function of the device. The LCD driver may be just a receiver, and the memory can send and receive data. In addition to transmitters and receivers, the device can be used as a hos

spread spectrum signal, such as using brute force injection (jamming) if your signal is sent to the signal to be disturbed (DoS attacks are denied), attackers must know this equation accurately, and the start time of using this equation (because the transmitter can change this equation at any time, so that it can be easily transferred to other frequencies ). therefore, the confidentiality of these equations in an application must be guaranteed.Most s

(such as a DSL voice or Cable Modem) together with the multi-service backbone transmission stream of other core IP delivery services, the transmitter may want these voice circuits to be controlled by some technology that understands their characteristics. In an open call model, various types of call control (such as MGCP for voice control, dedicated network for ATM transmission stream, network interface, PNNI, or MPLS for IP) the multi-service contro

reduced. A multi-hop Network node only needs enough transmit power to reach adjacent nodes. A single hop node must bear the maximum specified distance. In some applications such as distributed sensor networks, each node can be very close, so that the transmitter power is extremely low and the battery life is very long. Low-power nodes also effectively increase the total data capacity and network bandwidth. When two devices in a single-hop Network try

technologies need to be further improved to be applied to 5G network systems. Figure 1 5G will rely on the antenna array to provide a large amount of input and output (or MIMO); beam forming will direct the signal to a specific device. (Image Source: T-Mobile) It is still difficult to physically narrow the antenna size. The MIMO array for 5G is very large (this is one of the reasons why 5g smart phones were unlikely to become available even later before 2020 ). The power consumption of most ex

The advantages of twisted pair wires for Video Transmission indeed enhance our confidence in using the twisted pair wires for video transmitter in the project. However, there are still some problems in the actual product purchase and wiring applications, summarized as follows: 1) In order to enhance the anti-interference capability, use a shielded wire. Some friends, due to their long-term use of the same axis for transmission, unconsciously applied t
