Architecture and Application Based on Mobile Wireless LAN (1)

With the development of electronic and network technologies, people's lives are more closely related to electronics and networks. Mobile phones and mobile communication networks, computer and computer networks, and the Internet have become an indispensable part of people's life and work. In terms of technology, wireless and high speed are the ultimate goal of the network. From the economic point of view, cost and cost effectiveness determine the vitality and market of a product. However, people can believe that a high-speed wireless network that can make people think of a reasonable price and meet the needs of the vast majority of applications will inevitably be used in every corner of the world. At that time, people don't need much money. They can use their own devices, such as mobile phones and laptops, to make video calls, hold video conferences, and play on-demand online DVD movies. This is the ultimate goal of our generation.

With the goal of faster speed, stronger functions, fewer lines, more convenient to use, and simpler maintenance, future communication systems are moving towards integration, broadband, and wireless. Integration is manifested in two aspects: one is the integration of mobile communication networks and computer networks; the other is the integration of multiple functions of the same network, such as calls, tokens, and data. We have established a wired telephone network and a wired or wireless computer network within the company. This type of network reduces the contact between the internal network and the outside because it does not need to go through the center switching node of the network operator to realize internal communication of the enterprise, thus improving the security performance of the network to a certain extent. In particular, internal communication is free of charge. In recent years, with the development and maturity of WLANWireless Local Area Wetwork technology, new technologies and standards have emerged, such as ieee802.111mb/s ~ 2 Mb/s), IEEE802.11b (5.5 Mb/s ~ 11 Mb/s), 802.a (10 Mb/s ~ 25 Mb/s), Gbit/s (22 Mbit/s ~ 54 Mb/s) and HiperLAN2, HomeRF, and Bluetooth, wireless local area networks will replace traditional wired networks with their low overall cost, easy maintenance, and simple setup, enterprises and thousands of households. At the same time, we have established wired and wireless networks and computers that do not need to pass through the carrier-level switch center, with the increasing number of mobile phone users and the maturity of wireless computer network technology, the time has come for an enterprise or department to build their own mobile-based wireless LAN.

For a new unlimited LAN Based on a mobile phone, you only need to add a software module to the original computer wireless LAN and a hardware module to the mobile phone. This small amount of investment can make long-term profits, which is desirable and attractive for enterprises and ordinary family users.
