Wireless access technology and wireless LAN technology

To solve a network problem, we need to comprehensively use our wireless technology to achieve more effective use. Here we will discuss the wireless access technology and wireless technology in detail.

The wireless LAN technology combination based on IEEE 802.11 forms the best solution, providing high-performance access capabilities for local areas such as hotels, airports, and office buildings, it provides mobile wireless services (wireless WAN) for the ubiquitous access of mobile users ). The seamless combination of Wireless LAN/broadband and mobile phone services is called fixed mobile convergence. More than 1 billion mobile phones are put into use worldwide, and this number is increasing.

More than 0.13 billion of the world's broadband lines are in use, and this number is increasing. Fixed Mobile Convergence many users strongly want to replace wired phones with mobile phones. WLAN is developing rapidly in the era of enterprises, families, and hot spots. The combination of various factors in mobile and broadband cutting-edge technologies laid the foundation for promoting the development of fixed mobile convergence technology.

Mobile Wireless LAN technology options include cdma 2000 and its high-speed data overlapping EV-DO (optimized innovative data) and GSM/UMTS and its high-speed data overlapping HSDPA (high-speed downlink group access ). In addition to these options, two new IEEE mobile technologies are coming soon, namely 802.20 and 802.16 (WiMAX ).

In addition, there are other mobile data technologies, including general grouping Wireless LAN technology services (GPRS), EDGE, CDMA 1x and UMTS, which can support voice and data on the same RF carrier; however, in terms of spectrum efficiency, this is not the best data solution, because the requirements of conversational sounds are very different from those of data. The new high-performance Wireless LAN technology enables voice to be transmitted on one RF carrier and data to be transmitted on another carrier.

For end users, the advantage of fixed mobile service convergence is that the optimal wireless signal in time and space conditions is always used to achieve better connections. This solution is particularly advantageous when using mobile phones in buildings because Wi-Fi is in the optimal state, and mobile signals may be the weakest.

As far as mobile operators are concerned, the advantage of fixed mobile service integration is to enable them to seize communication services in most buildings occupied by cable operators, this accelerates the replacement process of fixed mobile technology. It also provides powerful support for broadband voice providers to deploy services in various geographical environments. These suppliers use the broadband IP Voice (VoIP) technology to win in-building services, and the cost is far lower than that of traditional operators. Dual-mode phones play a major role in providing comprehensive mobility for broadband voice. The fundamental advantage of operators is that they provide better user experience, which will help improve their competitive position and reduce the loss of customers.
