Abstract

In a portable gateway a bridge between two wireless networks is provided. The gateway has a small size and can be carried in a pocket or a briefcase.

Claims

1. A gateway for providing a bridge between two different networks, characterized in that the gateway is portable and provides a bridge between two wireless networks using two different antennas for providing the air-interface between the gateway and the respective wireless networks;

one of these wireless networks being a Bluetooth network, and one being a Wireless Local Area Network.

2. A gateway according to claim 1, characterized in that the antennas are positioned on opposite sides of the gateway, thereby spacing the two antennas apart maximally.

11. A gateway according to any of claims 1-10, characterized in that the gateway comprises an embedded server for configuring of parameters relating to the different networks.

3. A gateway for providing a bridge between two different networks, characterized in that the gateway is portable and provides a bridge between two wireless networks, and comprises at least one card slot for receiving a card constituting an interface to a wireless network.

4. A gateway according to claim 3, characterized in that the gateway comprises two card slots.

5. A gateway according to claim 4, characterized in that the two card slot entries, are placed on different sides of the gateway, and hence, the antennas of the cards are optimally spaced apart.

6. A gateway according to any of claims 3-5 characterized in that one of the two wireless networks is a cellular wireless network.

7. A gateway according to claim 6, characterized in that the cellular network is a GSM (Global System for Mobile communication), or a GPRS (General Packet Radio Service), or a UMTS (Universal Mobile Telecommunications System) network.

8. A gateway according to any of claims 3-7, when the gateway comprises one integrated antenna and one card slot, characterized in that the card slot entry, is separated from the integrated antenna, thereby separating the integrated antenna and the antenna of the card maximally apart.

9. A gateway according to any of claims 3-8, characterized in that one of the wireless networks is a Bluetooth network.

10. A gateway according to any of claims 3-8, characterized in that the card slot/slots is/are designed to receive a PC Card (PCMCIA) and/or a CompactFlash Card.
