spoofing attack, a common network attack means, can make the attack of the computer often appear online drop, slow speed and other symptoms) will be completely resolved. 4. Bandwidth Management The network resources (bandwidth) from the operator application is valuable, in the rental housing network, how these valuable resources (bandwidth) will be allocated to the Internet of computers, so that each computer on the Internet each line of the road, independent of the allocation of reasonable ban

This paper mainly describes the difference between competitive access and non-competitive access process under different scenarios.In the article "LTE-TDD Random Access Process (1)-purpose and classification" has been mentioned that random access can be divided into two types: competitive access and non-competitive access.Competitive scenarios include:(1) Initial access of UE(2) the reconstruction of UE(3) The UE has uplink data sent, but the

In an enterprise, a vro is uplinked to several organizations or companies, while a certain network segment or server in an internal network needs to access several uplinks at the same time, and all of them need to be accessed through NAT, if a server in the internal network needs to access the uplink units, how can I configure NAT? If only one uplink unit is accessed, it must be simple. A static ing is OK,

simplifies the wireless protocol as much as possible Establish uplink (from node to PC) and downlink (from PC to node) All protocols are built into the PC. The PC sends commands to implement the control logic, and the node is only responsible for running the work according to the working mode. The multi-channel method is used to solve the wireless interference problem. The automatic channel allocation algorithm is used to achieve the optimal recei

time division and Frequency Division multiple access technology, client terminals can use only a few carrier carriers in the uplink, so the transmit power is concentrated in these carrier carriers, can improve the signal-to-noise ratio of more than 10 db, to meet the needs of the notebook computer 0dB antenna room reception. 3.1 Mobile cellular broadband access Technology Mobile data service is basically a private network, download rate below lookb

Failure phenomenon: Video viewing is not smooth, the occurrence of screen delay and the situation of Carrington. Reason Analysis: This is generally related to the speed. Solution: Lenovo Wireless video service using high-definition cameras from the home network to upload video streaming to the internet for mobile phones and PCs to watch, need at least 512kbps uplink speed, in order to get a better viewing effect. At present the carrier provides A

, uplink using QPSK modulation. Using these techniques, the downlink rate of the asymmetric cable modem system can be as high as 30Mbps and the uplink speed can reach 2.56Mbps. It includes a plurality of cable digital modems Cablelink cm2000d and one or more cable modem front-end system cablelinkhs2000d on the front end of the CATV. The hs2000d includes an RF modulation and demodulation module and a channel

), point-to-point wireless spread spectrum communication in 5.725~5.85ghz frequency band, etc. Possible development of the frequency bands are: 5Hz Band of broadband wireless access 10GHz, 21GHz, 24GHz, 26GHz, 28GHz, 31GHz, 38GHz frequency band of LMDS (local multi-point distribution business) and so on. In 2000 more manufacturers launched the 800nm-band Broadband Wireless Infrared optical access system, become a veritable "wireless fiber."Generally speaking, the lower the frequency band, the lo

WCDMA is the abbreviation of "Wideband CDMA", which is translated into wideband coding and multiplexing transmission technology. WCDMA, as an important basic technology of TMT2000, will be the standard of the third generation wireless communication system. WCDMA is a third generation mobile communication system, which is developed by 3GPP, based on the GSM map core network and Utran (UMTS terrestrial Wireless access network) as the wireless interface. Currently, WCDMA has releases 99, 4, Relea

the system's launch requirements for eb/no. The experiment shows that the receiving diversity of 4-day line can increase the sensitivity of the system to up to 23dB, and achieve -130DBM (the protocol is only -125dbm), compared with the ordinary receiving diversity. As the current user terminals generally do not support multiple antennas to receive, so 4-day line reception is mainly used for uplink reception. (Computer science) Theoretically, the 2dB

FTTD (Fiber to the Desk) cabling scheme is attributed to the overall FTTx system, FTTD as a high-level solution for cabling systems, the industry is well aware of the excellent transmission performance of fiber as a transmission medium, but also due to the high price of optical fiber active equipment, Led to few projects in the past few years large-scale use of FTTD wiring. In the rapid development of FTTX access network today, especially the development of FTTH networks, due to the overall indu

computers in the LAN to share a public IP address to surf the Internet and implement corresponding functions. Ii. Used for vswitches Broadband routers include wireless routers) generally have a built-in four-port switch, so you can directly use it as a real switch. Many readers may ask, isn't there an UPLINK port on the switch? However, no four vswitches are built in the Broadband Router. In fact, the UPLINK
