WAYNE, N.J. NewLogic Technologies has developed an algorithm that will allow the company to add 802.11h support to its wireless LAN (WLAN) intellectual property (IP) core line up.
802.11h is an extension that allows 802.11a systems to comply with European regulations for 5 GHz WLAN operation. Through 802.11h, designers of access points and ad-hoc systems can add transmit power control and dynamic frequency selection to avoid collision and interference two important elements needed for operating in 5 GHz European bands.
To provide 802.11h support, NewLogic has added a radar detection algorithm to its WLAN IP blocks. According to the company, the detection algorithm delivers a low false alarm rate and can detect pulses with 99-percent probability.
The radar detection algorithm is available today. It will be implemented in the company's WiLD family of IP blocks, which includes a dual-band CMOS radio, a triple-mode media access controller (MAC), and triple-modem modems.
