Debug fiber Interface interface with FPGA:Due to the needs of the project, the previous period of time debugging the optical fiber interface, recording some design experience.In the design, FPGA is used to control optical fiber module to complete the transmission of optical fiber data, FPGA uses Xilinx company's Spartan6 lx45t, because of its internal 2 GTP transceiver, can be used as a variety of communication protocol (Gigabit Ethernet, Pci-e,sata,

protocol stack send function, to achieve data wireless transmission③ Receive: Receive node calls the protocol stack wireless receive function, realizes the wireless data receivesSince the protocol stack encapsulates these functions, it is convenient for us to use them. Here is the protocol stack wireless send function:A better application of the protocol stack requires a detailed understanding of the specific role and significance of these functions and their parameters provided by the protocol

are no special application requirements, it is advisable to select the device in these two companies.Hardware Resources for 5.1.2 devicesHardware resources are important criteria for device selection. Hardware resources include logical resources, I/O resources, cabling resources, DSP resources, memory resources, phase-locked loop resources, serial transceiver resources, and hard-core microprocessor resources.The need for logical resources and I/O res

number of tasks of Integrated Wiring. However, twisted pair wires have weak anti-aging capabilities, and only one image can be transmitted at a time. Therefore, it is suitable for video surveillance of network cameras in medium and short distances, with relatively scattered camera points, or with relatively close but concentrated points, such as banks, hotel chains, supermarkets, or university campuses. Optical fiber.Optical Fiber Transmission has the following advantages: long transmission dis

parabolic surface, so that the antenna is located in the parabolic surface of the internal reflection focus, through the electromagnetic waves reflected in the focus of the formation of energy concentration, thereby enhancing the electromagnetic signal transceiver, To achieve enhanced signal in a specific direction. The key to making a simple gain antenna is to find a more regular metal parabolic surface and compute the focus position of the parabo

direction, and if any network segment are severed, all network transmission ceases. A host on a bus network is called a station or workstation. In a bus network, every station receives all network traffic (traffic), and the traffic generated by each station have equal Tran Smission priority. Each network segment is, therefore, a collision domain. In order for nodes to transmit on the same cable simultaneously (simultaneous), they use a media access control technology such as car

multicast distribution service, is a broadband point-to-point access system that can access voice, data and video services. LMDS system using millimeter wave transmission, working in the 20-40ghz band, can provide up to 155.52Mbps user access rate, known as a "Wireless optical fiber" access system. In addition, the LMDS system supports all major voice and data transmission standards, such as ATM, TCP/IP, and MPEG-2.The *LMDS system adopts a kind of honeycomb structure configuration, by which on

Topic Links:ah haha, dot me dot MeTest Instructions:A region of the Arctic has n villages (1≤n≤500), each of which is represented by a pair of integers (x, y), of which 0≤x, y≤10000. In order to strengthen linkages, it was decided to establish communication networks between villages. The communication tool can be a radio transceiver, or it can be a satellite device. All villages can have a radio transceiver

transceiver lamp "Normal", the user is God, I believe you once, but still not pass ah, suspicion is the user firewall or internal network problems, let users restart equipment, and then contact the user. The phone rang again, looking for someone, OK! Give a turn, just hang up the phone, telecommunications pass to the phone, ask us to do not network export access, I said do not need, this brother really dedicated, have to grind with me, I am anxious!!
