Bluetooth access point to provide more than seven users
First Claim
1. A Bluetooth LAN Sectored Access Point as shown in FIG. 2 comprises an Ethernet transceiver, a microprocessor, Flash memory, SDRAM memory, an embedded USB host controller, which can drive and communicate with up to (but not limited to) 4 slave devices, 4 respective Bluetooth radio modules as USB slave devices, and 4 respective 90 degree sector antennas to cover a quarter of the piconet called Sector Piconet. Each Bluetooth radio module in the Access Point is assigned as a master and take care of each sector and can communicate with up to 7 Bluetooth enabled wireless devices (called Bluetooth slave devices) at 2.4 GHz ISM band.

Abstract
The invention introduced in this patent application introduces a new Bluetooth Access Point, which applies the “sector idea” to its pico cell network and divides a pico cell into four (4) (but not limited to 4) pico sector of 90 degree. The access point thus implemented is denoted as Sectored Access Point. The Sectored Access Point utilizes only ONE microprocessor to communicate with four Bluetooth modules via either an embedded USB host controller with four ports to drive respective Bluetooth modules or UART interface with also ports to interface with respective Bluetooth modules. Each Bluetooth radio module acts as a master in its respective pico sector and takes care of up to seven (7) simultaneous Bluetooth enabled devices (called slaves in this cell). Therefore, the Access Point in this case can provide 28 users to access Internet at the same time, which is fourfold of any commercially available Bluetooth Access Point. The Sectored Access Point costs almost the same as normal access point, except 3 more Bluetooth radio modules and antennas, which contribute only about 10˜20% of extra cost, but increase the capacity by four times.
