(b) description of the current State of the art

With the progress of wireless data transmission was their use to browse network content, transfer data, search the web, for e-commerce, Lessons, online games and the exchange of e-mail to one increasingly important component of modern data transmission technology. In the course Development has resulted in various transmission protocols and technologies (e.g. WLAN, WAP, GPRS, PHS, CDMA, DECT, 3G). Except that so the user given a choice, they are also technically different and have each with their own strengths. The number of applications in all types of devices is constantly increasing. For the Modern man is the wireless transmission technology to one become extremely important medium.

Currently common wireless routers can due to their construction only in the wireless local area network (WLAN according to IEEE 802.11b, 802.11a or 802.11c). Around as a transmission medium needed to be usable Wi-Fi however has an access point and the user needs to log in the range of the system. It is therefore more for areas high density users or selected locations (e.g., airports, destinations, authorities) suitable. In remote locations is a network access through wireless internet therefore not possible.

If a system succeeds without the above-mentioned disadvantages, which flexible access also to other wireless systems high data transmission speed allowed, this is a big step after.

SUMMARY OF THE INVENTION

main goal The present invention is a system with an interface slot, which allows it by inserting a suitable interface card with real-time protocol conversion for a radio network (e.g., GPRS, PHS, CDMA, UMTS, DECT, 3G, etc.) connect to different communication networks to enable.

secondary objective The present invention is by use of the interface card with real-time protocol conversion the connection of networks with different transmission protocols to enable what kind of the most different countries and ambient conditions would or would allow the most cost-effective depending on the environment Select connection method.

One another goal is to enable that by adding an internet IC and an internet connection also a wired connection can be made to the Internet.

Of the Connection via the wireless router with interface slot for cards that come with different Logs for the wireless transmission (e.g., GPRS, PHS, CDMA, UMTS, DECT, 3G, etc.) work on different ones Communication networks where the user has a wireless local Network (WLAN) or a wired local area network with can be connected to the wireless router, thereby allowing one wireless connection to the internet. This allows the user then browse through the network, transfer data or send or receive e-mails. By connecting a second Network ICs and an Internet port between microprocessor and Network IC is a wireline connection of the wireless Routers to the Internet (WAN) possible. In this way, the user has various options for dynamic Connecting to the data network, which allows him bottlenecks and interruptions too avoid.
