on mobile voice services, however, the performance evaluation results of traditional MANET for VOIP services are always unsatisfactory. Here, people are very concerned about whether the wireless mesh network can meet the quality requirements of users for real-time voice services.
Iometrix, a professional testing company, conducted the first performance evaluation and testing of Wireless Mesh Networks Based on the draft study by the IEEE 802.11 Workin
Overview explanation
VoIP is the abbreviation for voice over Internet protocol, meaning to transmit voice over the Internet (Internet). VoIP technology is also often referred to as network telephony, IP telephony, or Internet telephony technology.
VoIP's most basic function is to provide internet-based, low-cost voice and fax services. It can also extend further to ip-based voice services.

When the enterprise consolidates the data center and voice technology, it may consider the environmental conditions to meet the needs of the new equipment, but when the enterprise switches from TDM to IP, it is often neglected to meet the needs of the wiring room.
When you deploy IP phones to the desktop, users will soon face the same problems as local broadband providers, which may cause the system to fail to function properly, or to invest at a higher cost. The main problem is how to power a
With the development of China's routing industry, we have also promoted the update and upgrade of the VoIP router technology. Here we mainly introduce how to do a good job in the security vulnerabilities of the VoIP router technology. As the bandwidth of the Data Network continues to expand, it is possible to reach the desktop by Mbit/s or even Gbit/s. The increase in bandwidth also provides powerful precon
VOIP, also known as IP phone or IP phone, is the abbreviation of Voice Over IP. This technology is used to encode, digitize, compress, and compress Voice signals into Compressed Frames, then, the IP packet is converted to the IP packet for transmission over the IP network, thus achieving the purpose of voice communication over the IP network. The IP Phone greatly improves the utilization of network bandwidth and reduces the communication cost. its wid
VoIP has become a major topic in the era of integration. How to better utilize the functions of VoIP in the aspect of open-source and throttling, and reduce the communication costs of enterprises and individuals has also become a common concern in the industry.
At the beginning, as a technology used in Internet applications, VoIP was widely loved by Internet user
As VoIP continues to replace analog phones in the enterprise voice communication market, this technology is also rapidly adopted in residential environments and Small and Medium-Sized Enterprises (SMBs. The advantages of VoIP, such as multiple lines, the use of cheap digital media voice communication systems, and significantly reduce the communication rate, not only for large enterprises, but also for small
We now have a lot of knowledge about VoIP technology, and we are almost at risk to talk about other applications and usage knowledge. In the use of VoIP technology, we will transmit voice signals in the IP network. However, there are also many technical needs to achieve long-distance IP network spanning.

Implementation principles and key technologies of VOIP: basic principles and implementation forms IP telephone systems convert analog signals of common telephones into IP data packets sent by computers over the Internet, at the same time, it also converts the received IP packet into a sound analog electrical signal. After the conversion and compression of the IP Phone System, the transmission rate of each common phone is approximately 8-11 kbit/s band
