system for large bandwidth has become its relative to single-carrier technology (such as CDMA) "decisive advantage ". Multi-path fading Resistance Because OFDM converts broadband transmission to narrowband transmission on many sub-carriers, the channels on each sub-carrier can be seen as horizontal fading channels, which greatly reduces the complexity of the receiver's balancer. On the contrary, the complexity of multi-path balancing for single-carri

Currently, the competition in the mobile communication Operation Market is becoming increasingly fierce. Judging from the 3G development in Europe, America, Japan, and other places, "Fast fish eat slow fish" has become the industry standard, whoever can quickly deploy a high-quality 3G network can take the lead. Overseas operators have many commonalities in creating 3G networks, including choosing partner standards, 3G network construction strategies, network deployment methods, and technical di

routing technology. The factory settings of some Broadband Router products are still IP balancing by default. Although there are few opportunities for such applications to encounter problems, such as QQ and bubble Hall support, they sacrifice the advantages of multi-wan. Strictly speaking, IP balancing is equivalent to the superposition of two or more single WAN products. Second generation: Server Load balancer or Dual Network The second generation of Multi-Wan routing technology includes two t

%. Broadband refers to the modulation of multiple audio and video channels and control signals to different carriers to make full use of the coaxial cable resource space. The coaxial cable integrates audio and video and control signals modulated to different carriers into a coaxial cable for bidirectional transmission. Therefore, the "one-wire-to-one" two-way transmission platform for multi-system and multi

to decline over time, so the advantage of PON to save optical fiber cables is not prominent today. At present, the main target market of FTTH in China is undoubtedly the residents of residential communities in small and medium-sized cities. Urban residential communities are generally garden-type residential communities. Their prominent features are: high household density, residential areas include commercial buildings) generally, communication equipment rooms are used to install communication

As an evolution after 3G-4G, do you know its technical characteristics? As one of the 4G standard record filing systems, wireless TD-LTE-Advanced adopts the multi-access method, frame structure similar to TD, and wireless MIMO technology. The following is a detailed introduction. Features of wireless TD-LTE-Advanced Technology 1. Multiple Access Method The wireless TD-LTE is based on OFDM technology, and OFDMA is used in the downlink. the uplink adopts the single carrier DFT-SOFDM as the multi-a

supply, and O M, regulatory Policies and many other factors. Therefore, carriers need an integrated and full-scenario FTTx solution that can meet the requirements of CO, FTTC, FTTB, and FTTH, FTTO and FTTM can also provide copper, P2P, and P2MP access. High reliabilityAs the OLT capacity increases, the number of covered users increases, and it also carries Enterprise access, mobile bearer, and other services. The FTTx network reliability requirement

The downlink sub-frame consists of three parts: Preamble (Preamble), FCH (frame control header), and downstream data burst. Preamble is located at the beginning of the sub-frame of the upper and lower lines. It is used for synchronization between the receiving and sending machines and channel estimation. The symbol structure can be divided into long preamble and short preamble: long preamble is used for downstream sub-frames and consists of two symbols. The first symbol appears every four sub-

than 250 M away from the end user, with a target bandwidth of 500-1000 M per household. As you are closer to the user, you can get a relatively higher bandwidth, and G. fast will be used as a gigabit access solution comparable to FTTH. Unlike previous technologies, G. fast introduces user-defined concepts at the initial stage of standard design. Traditional copper wire access technologies, both ADSL2 and VDSL2, are fixed upstream and downstream bandwidths. In most cases, the downlink bandwidths

Explore the future of TOSCA and NFV, and explore the future of TOSCANFV Standardization and unification have great advantages, but they also face great risks. The worst of these is the lazy idea. In a world filled with changes, we are too cautious. We trust standardization organizations too much and lack bold and imaginative plans. This article will discuss the risks of open standards, open-source specifications, and excessive standardization and possible NFV standards. Standard In the telecom

If a Cisco Wireless Router is improperly configured, problems such as disconnection and disconnection may occur. It is very important for us to have a deep understanding of the details in Cisco wireless router configuration. Next we will introduce the relevant knowledge in detail. As we all know, wireless signals are the carriers of data transmission, which means that the stability of wireless networks has a very direct relationship with wireless sign

For wireless routers, we have used them very frequently. But how can we set them during the networking process? What are the differences between our routers through a series of settings? As we all know, wireless signals are the carriers of data transmission, which means that the stability of wireless networks has a very direct relationship with wireless signals. In fact, to make the wireless router in a very stable state, you must make a series of rea

The next generation network is becoming a new revolution in communication technology. Who can quickly adapt and who can quickly provide value-added services to different users can master the key to business success.In today's fierce competition in China's telecom market, major operators are actively seeking for next-generation network solutions.

Introduction Communication providers and their partners and users are increasingly eager for a new generation of IP-based services. Now we have the SIP Session Initiation Protocol. SIP was born less than a decade ago in the computer science laboratory. It is the first protocol suitable for multi-user sessions in various media content. Now it has become the specification of the Internet Engineering Task Group (IETF. Today, more and more carriers, CLEC

customer service: if the answer is "no mail/yes", it must be no mail. However, if the answer is "blocked/not clear/unclear", it can be understood as "the possibility of sealing is very high ". If you don't get a clear answer, you just need to check whether the people around you use a vro or go online and check what the "local" Netizens say. How can I test the account and password authenticity? Why is there another authenticity problem with the account and password? Because some

Because some carriers, routers, browsers, and so on will intercept requests in non-200 states, and then change them to their ads or custom pages. then the question arises. ask your friends where laravel is; can all returned status_code values be controlled? What I want to achieve is... some operators, routers, browsers, etc; Requests in non-200 status will be intercepted, and then changed to their ads or custom pages; So the question comes. ask your

, but I don't know why, online is always unstable, data is often not transmitted, and you have to re-connect. This situation may be caused by the instability caused by the establishment of VPN networks across different carriers. For example, the Headquarters uses the lines of China Netcom, while the branches use the lines of China Telecom, resulting in insufficient cross-network bandwidth, and the phenomenon. In this case, you can also use a multi-WAN

Huawei launched the World's smallest operating-level Router Atom Router at the Mobile World Congress 2014 today ). This atomic router can be deployed on any node or device on the current network, and can be visualized and managed without modifying the current network, provides high-precision Performance Detection for each user and business in real time, helping traditional networks increase network value. This major breakthrough focusing on customer needs demonstrates Huawei's leading strength a
