The boundaries between the internal and external networks of enterprises are becoming increasingly vague, and the mobility of users is getting stronger and stronger. In the past, we thought that the secure internal lan has already posed a latent threat. It is difficult for us to ensure that the virus will not be brought into our enterprise network, an

cannot obtain broadband cable infrastructure support beyond the DSL service scope. However, these problems can be solved by using wireless broadband access technology. The wireless broadband access technology provides faster network deployment, stronger scalability, and higher flexibility. Therefore, it can provide services for customers who are unable to enjoy or are not satisfied with their wired broadband access. Currently, the mainstream wireless access technologies include 3G, Wi-Fi, and W

wireless services. The NGMN project aims to set up clear performance objectives, propose specific requirements, and deploy the broadband mobile network in the future for the next 3G technology evolution direction, to guide the formulation and development of next-generation mobile network standards [1]. NGMN also faces a variety of network interconnection and convergence issues. Figure 1 shows the system architecture of NGMN in the future and the coexistence mode between NGMN and the current mob

, WiMAX in a very long time will be the main solution to the hotspot coverage, the network can provide some of the mobility. 3G is continuous coverage, the user to the full mobile-based.From the perspective of business capability, WiMAX is mainly a broadband data service with certain mobile characteristics, and the main users are notebook terminal and 802.16e terminal holder. 3G from the design is originally designed for voice services and Data Servic

, it is from the realization of mobile office, improve efficiency, it does not bring you a direct increase in profits, but will increase your IT construction costs, if combined with maintenance management, TCO (total cost of ownership) may increase a lot. But the portability of mobility is unparalleled, such as the company's internal meetings, Internet telephony, will be more convenient, if it is to achieve the FMC (wired and Wireless fusion network),

At present, China's wireless access network is still developing very rapidly. It may be irrelevant for many people to learn about the interfaces in the grouping system in the wireless access network. After reading this article, you will certainly have a lot of GAINS, I hope this article will teach you more things. Introduction to the interfaces in the evolved grouping system Gi InterfaceGi is the interface of the external grouped data network of the wireless access network, and also the display

A Unified Communication System that is intertwined in communications and networks brings intelligent and information-based work models to enterprises. However, although many enterprise vendors are optimistic about this platform, competition is everywhere. So let's analyze the advantages of the Unified Communication System and its cooperation with the benign competition. Unified Communication Systems and mobility are the two major trends of Enterprise

When talking about the Unified Communication Technology System, I don't know if you can fully integrate the services it contains. Many of my friends have reported that the current UC market and vendors have their own understandings and understandings of Unified Communication, and there is no normative definition. However, the basic services of the Unified Communication Technology System are similar. Unified Communication Technology Systems and mobility
