headquarters uses Cisco, then the division also uses Cisco. ” Branch Office wireless network products There are some key differences, enterprises should know the following points before selecting suppliers for branch offices. Remote Diagnostics Resolving a network connection is a problem for a branch office because you can't see the wireless signal. And that's where the spectrum analysis technology works. At the corporate headquarters, you can use

factors: User requirements: To consider the type of business and the density of traffic, but also consider its performance price than the majority of users can withstand. Spectrum efficiency: To analyze the characteristics of different air interface technology system, especially its spectrum efficiency can support the growing requirements of users. Radio coverage: To determine the availability of the ap

In speech denoising, the most commonly used method is spectral subtraction, spectral subtraction is an early development and the use of more mature speech denoising algorithm, the algorithm uses the additive noise and speech is not related to the characteristics of the hypothesis that the noise is statistically stable, the noise spectrum estimation without the voice gap is calculated to replace the voice period noise

: Set 1 to say that there is a voice, 0 for no voice (mute or very weak sound), the reference Terminal (remote) signal X (t) and the receiving end (proximal) signal y (t) may be combined in the following ways: (0,0), (0,1), (1,0), (), (0,0) indicates that both the far end and the proximal side are relatively weak, and that the remote and proximal are relatively strong sounds, and that the C code of WEBRT is not possible by default in two other cases. At the time interval p, i.e. p=1,2,..., P,

that the data rate is higher, the security is better and the quality of service is more and more guaranteed. And from the wireless LAN standards of the supporters and the geographical scope of use, wireless LAN can be said to have three camps: IEEE 802.11 series of standards, European hiperlan1/hiperlan2 and Japan's MMAC series standards. 802.11 series Standard In the 802.11 series, there are 4 standards involving the physical layer: 802.11, 802.11b, 802.11a, 802.11g. According to different

of up to 8Mbps, uplink rate of 640kbps, and adsl2+ downlink rate of the highest for 24Mbps, the uplink rate of 1Mbps. From the transmission rate, ADSL is difficult to meet the high bandwidth users access requirements, adsl2+ in the near future can basically meet the bandwidth needs, but the uplink bandwidth is low. Following the first generation of VDSL, the ITU passed the VD-SL2 in May 2005 (second generation VDSL) The standard G.993.2,VDSL2 has good application foreground by extending

suspected that pilot contamination may exist, the first possibility is that there is not enough protection in pilot planning, and the other may be that the time tolerance of pilot channel of some base stations has a large deviation. For the latter, a transmitter tester can be used to test the potential base station. (Computer science) The user complained to the warning and network management reports that there is a problem with the call, and has ruled out base station and base station day feed

each channel (8 MHz) is time-division multiplexing transmission, the channels are still transmitted in frequency-division multiplexing mode. 1.2 orthogonal frequency division multiplexing Orthogonal Frequency Division Multiplexing is a multi-carrier digital modulation technique. All OFDM carrier frequencies have equal frequency intervals, which are an integer multiple of the basic oscillation frequencies. Orthogonal means that the signal spectrum of

at a transmission rate of up to 22 Mbit/s with a single-carrier bandwidth of 6 MHz, the spectrum efficiency is high. The communication probability in the 90% GHz band can reach 80%, and the communication probability in the GHz band can reach more. A high-frequency microwave SDHIP ring system. In the past, many microwave SDH devices were used in point-to-point microwave transmission circuits. Now with the advancement of technology, some companies have

technology is much simpler, and it has a huge advantage in transmission rate and cost. UWB has the following features: 1. strong anti-interference performance: the wireless UWB technology uses time-hopping spread spectrum signals, and the system has a large processing gain. When transmitting, the system disperses weak radio pulse signals in a wide band, the output power is even lower than the noise produced by normal devices. The signal energy is res

than 80% of the service data on the entire network, these 30% base stations have high configuration and capability requirements. The third challenge is misplacement of network configurations, cross-generation systems, differentiated services, and cross-generation terminals, as a result, if you want to enjoy a faster network service, you must replace the terminal. "At the same time, with the development of the user scale, the interference between different operators in the system and between sys

capacity density required by the rapidly growing mobile Internet bandwidth, the number of small cellular networks in some specific regions is much larger than the number of existing cellular networks. This also represents a new and very important back-to-back challenge because of the installation location of these small cell nodes (such as wire poles or other sub-district assets ), it is rarely suitable for optical fiber or microwave solutions. The concept of LTE self-return or Mesh technology

(such as an infinite time domain input signal, how to get the output signal). We look at the Fourier transform as a function of the C language, the output and output of the signal as an IO problem, and then any x->y problems that are difficult to solve can be obtained with x->f (x)->f-1 (x)->y.1. What is frequency?A basic hypothesis: any information has the characteristics of frequency, the sound level of the audio signal, the spectrum of the light,

Given A string arraywords, find the maximum value oflength(word[i]) * length(word[j])where the words does not share common letters. You may assume this each word would contain only lower case letters. If no such and words exist, return 0.Example 1:Given["abcw", "baz", "foo", "bar", "xtfn", "abcdef"]Return16The both words can be "abcw", "xtfn" .Example 2:Given["a", "ab", "abc", "d", "cd", "bcd", "abcd"]Return4The both words can be "ab", "cd" .Example 3:Given["a", "aa", "aaa", "aaaa"]Return0No suc

explore how to use colors effectively on the site, while also providing a number of color blending techniques that allow you to use colors to harness your web design. Color Science We can see that color is formed by interacting with three elements: the light source, the reflective properties of the object, and the way the human retina and the visual cortex of the brain interact with light waves. No matter what media we use to work-painting, printing or networking-we all have to rely on the ab

802.11 standard802.11 standard Introduction:IEEE 802.11 is a common standard for today's wireless LANs and is the standard for wireless network communications defined by the International Institute of Electrical Engineering (IEEE).It defines the media access control layer (MAC layer) and the physical layer. The physical layer defines two types of spread-spectrum modulation and an infrared transmission on the 2.4GHz ISM band, and the total data transfe

The frequency domain representation of the subtraction sample can be viewed from two angles:1. Directly from the original signal point of view, this needless to say, according to the new sampling frequency of the original signal spectrum directly normalized to the digital domain on the line;2. From the existing spectrum perspective, can be introduced (refer to discrete-time signal processing):Xd (ejω) = (1/
