Embodiment Construction

[0019] Relevant detailed description and technical contents of the present invention are now described as follows in conjunction with the accompanying drawings: the present invention is a wireless data card with PHS and WLAN functions, belongs to the PC card of type two, and is used by inserting the PCMCIA slot of the PC. The interface specification with PC meets the Card Bus7.0 specification. The hardware devices on the card can be divided into WLAN subsystem and PHS subsystem, wherein WLAN subsystem supports 802.11b / g standard, and PHS subsystem supports 32Kbps / 64kbps PIAFS standard connection. Therefore, it can be regarded as a complex of WLAN network interface card and PHS data terminal. On the one hand, it can provide WLAN wireless access through the WLAN subsystem, and on the other hand, it can provide dial-up access through the data link provided by the PHS subsystem. the Internet.

Abstract

The double mode radio data card with PHS and WLAN function includes WLAN processing part and PHS processing part. The WLAN baseband processing chip is connected to Card Bus, and data / signal connected via one interface conversion circuit to PHS baseband processing chip, so that the PHS processing part can share the Card Bus interface of the WLAN baseband processing chip to complete the integration of two kinds of system in one data card. The present invention realizes the compatibility of data card to both PHS and WLAN functions.

Description

technical field [0001] The invention relates to the communication field, in particular to a dual-mode wireless data card with PHS and WLAN functions. Background technique [0002] At present, mobile computing devices such as notebook computers provide wireless data transmission services by using devices commonly known as PC cards. PCMCIA (Personal Computer Memory Card International Association) defines the corresponding electrical, mechanical, and software interfaces of PC cards. At present, there are three specifications and sizes of PC cards, which are type 1, type 2, and type 3. Type 2 PC cards are often used in equipment that provides wired or wireless Internet data services for PCs, such as network cards and data cards. [0003] The current wireless data communication methods that can be used by notebook computers include wireless local area network (WLAN, Wireless Local Area Network), wireless wide area network, etc. The IEEE802.11 protocol belongs to the communication...
