Embodiment Construction

[0056] In order to realize the above functions, some wireless interfaces of HSDPA, WLAN (Wireless LAN) wireless interface, RJ-45 Ethernet interface, LCD (liquid crystal display) control, keyboard control, routing protocol and data exchange between HSDPA and WLAN need to be completed. Since WLAN works in the 2.4GHz frequency band and GSM / WCDMA works in the range of 800MHz to 2100MHz, the two parts require different antennas and circuits to realize data transmission and reception.

[0057] Such as figure 2 As shown, the WLAN part of this design adopts the single-chip solution of SOC (System On Chip), and realizes the WLAN and Ethernet access functions under the condition of only adding a few peripheral chips. The WLAN central processing unit 203 completes encoding and decoding of WLAN signals, up-conversion modulation, down-conversion modulation, realization of WLAN protocol stack and encoding / decoding of Ethernet signals. The modulated radio frequency signal is amplified by t...

Abstract

The invention provides an access interface of WAN network data for an HSDPA mode which uses a 3.5G wireless communication mode, and the wireless net surfing function for as many as 253 users simultaneously can be provided in WiFi mode at the accessing end of a local area network, and the invention also supports 4 standard Ethernet surfing interfaces simultaneously. The beneficial effect of the invention is providing an economical and effective net surfing mode for the users who use fixed access with inconvenience or who often move.

Description

technical field [0001] Completely change the existing way of wired access to the Internet. The 3.5G wireless network is used to provide network services for homes, offices and other places that require ISP (Internet Service Provider) services where wired access is inconvenient. Background technique [0002] The existing wired network access technology is mainly used in densely populated cities and towns where calls are made to the home. But for plateaus, mountainous areas, grasslands and pastoral areas where the population is sparsely populated and the telecommunications infrastructure is weak, it is still impossible to provide wired Internet services. [0003] The present invention uses the HSDPA (High Speed ​​Downlink Packet Access) mode in the 3.5G wireless communication mode to provide the access interface of the WAN (Wide Area Network) network data, and at the same time uses the WiFi (Wireless Fidelity Wireless Local Area Network) mode at the access end of the LAN Pro...
