communications industry, WiMAX has become a new hot spot, which is favored by many manufacturers. 1. WiMAX to the mobility of evolution. At present, WiMAX is developing mobility support, the IEEE is actively developing 802. 16e. 802. 16D is a fixed wireless access technology, while 802. 16e's goal is a mobile broadband wireless access technology, including: support Speed mobile 120km/h, can provide broadb

public WLAN network basic extension structure has peer-to-peer interconnection, AP structure, wireless bridge structure. The following is a brief description of the structure with an access point. A typical WLAN topology has an access point structure that is suitable for wireless access services in which access points are used to perform synchronization and coordination, forward packets, and connect to the upper network. The number of users the access point can service is related to the produc

Missing features: Aerial effects feature, live thumbnail preview, Internet Connection Sharing. Available: Only in emerg

latter can be divided into plane routing protocol and hierarchical routing protocol. 3. Plane routing protocols include on-demand routing, such as on-demand distance vector protocol, Dynamic Source Routing Protocol (DSR), segment-by-segment routing protocol (SSR), and active routing, for example, the distance vector (DSDV) of the destination station number, the wireless routing protocol (WRP), and the topology broadcast based on reverse path forwarding. the hierarchical routing protocol include

IPV6 video monitoring seems to have come to our eyes. At present, the network is from IPv4 to IPv6, and video monitoring must be v6. Now let's take a look at this consultation. Under the new network protocol, what will happen to our monitoring system? Once the IPv6 transition of the basic network is complete, the network video monitoring device will inevitably transition to IPv6. IPv6: helps monitor the Internet At present, with the development of security technology, traditional CCTV-based anal

departments into different VLANs and map VLANs to different IP subnets. Therefore, the IP subnet policy is applicable to scenarios with low security requirements, network Design with high demands for mobility and simple management. The following command is usually used to set an IP subnet policy VLAN: Vlan 1 ip address 192.168.10.0 255.255.255.0 When the IP address of the user terminal is set to 192.168.10. *, the terminal automatically enters VLAN 1

We went to Singapore for mobility Metro training during the Spring Festival. Many MVPs and MCT members from across Asia attended the training. The purpose of this training is to quickly promote the latest technologies developed by Windows Mobile 6.0 and Visual Studio 2008 to the world. We will also launch a series of mobility Metro training in China. A total of four people went to Singapore for training thi

recommend that you port the tool properly, so that errors may be compared. 1: Build a development environment. You can directly use the qtsdk and install it. But I do not recommend this because of the following reasons: ① The ID of QT creator is very immature. Many inexplicable errors may occur during compilation and debugging, and the GCC compiler itself is very slow. If the project is large, the Compilation speed is sufficient, this greatly reduces the development efficiency and project prog

For the development trend of the Communication Industry in 2013, the majority of suppliers, service providers and analysts predict that there will be a convergence trend of Cloud technology and mobility. However, cloud computing represents different content in many different markets. The emergence of this convergence trend has led to some changes in cloud computing. The development of mobility means that we

Wireless LAN (WLAN) has the advantages of convenient installation, good mobility, flexible use, and easy expansion. However, many new problems have emerged in the planning, design, testing, and security management of WLAN. 1. Features of Wireless LAN The MAC protocol of WLAN is different from that of Ethernet. The transmission protocol of Ethernet is CSMA/CD ), the standard wireless network uses a MAC mode of CSMA/CA (with multi-channel access for ant

Service (QoS) assurance. The IPv6 Header does have some improvement in performance. For example, the checksum field is removed, but this is not the same as the so-called QoS warranty. Currently, the technologies that address IP QoS are DiffServ, InterServ, and Multi-Protocol Label Switching (MPLS), which are applicable to both IPv4 and IPv6. In other words, IPv6 uses the same technology as IPv4 to solve the QoS problem. Without IPv6, the service quality will be guaranteed. (2) security assuranc

band and the same technical device. In multi-carrier environments, the frequency interference between different AP (AccessPoint) significantly reduces the data transmission rate, and the simultaneous high-speed data service for multiple users cannot be implemented in environments where three operators operate simultaneously. In the process of transmitting radio waves, different obstacles may lead to refraction, reflection, diffraction, and signal penetration failures. The quality and Signal Sta

, including user nodes with Strong Mobility and limited power consumption, and weak mobility, access nodes and gateway nodes with unlimited power consumption. Currently, when designing the vast majority of WMN routing protocols, the Mesh clients and Mesh routers are treated equally without considering the differences between the two, and the two types of nodes are distinguished to study the routing protocol

As a result of the project, the boss asked me to build a wireless mesh network using the ARM Development Board (tiny6410 of friendly arm). Generally speaking, the network equipment of the wireless self-organization network is to be acted by the user's terminal apparatus, these terminal equipment must handle the user's application data, such as entertainment, office and so on all aspects data, but also acts as the router, carries on the route forwarding; For the former, most of the hardware and s

Access Point internal protocol and its implementation on the Access Point (1) The IEEE 802.11 Protocol defines the specification and basic structure of the MAC layer and physical layer of the wireless LAN, but does not specify the construction of the wireless LAN. This leaves a lot of free space for the function design of the AP and its distributed system, but it also brings problems to the movement of the STA on the wireless site, this prevents Stas from freely moving between APS produced by d

, which is the source of the IP site vulnerable to attack.(2) Mobility and multiple URLsThe dual role of IP address network layer addressing and Transport Layer locator identifiers limits mobility and multi-url flexibility. In particular, the transport protocol binds the address to determine the communication session, and if the address changes, the session is interrupted and the connection needs to be re-

for user interface design. All institutions must acquire new skills and work with new partners to meet the growing needs of their users.7. Enterprise Mobility ManagementThe Word Enterprise mobility Management (EMM) explains the future evolution and convergence of technologies such as mobile management, security, and technical support.

mobility strategy, they say, "Can we get an idea from our business unit to prototype in a week, quickly implement it, throw it out and test user feedback, and then change it based on this prototype?" This fast-initiating, fast-validating, fast-tuning approach has become a popular method. In a short time, the business from the idea into a reality, even if it is a rough point to achieve, the root cause is that the business of innovative ideas may not b

Second, the platform involves a large, once can not well fit, the consequences are fatal. ”"There are many examples of ERP failures in large enterprises in China.
