We haven't heard much lately about the IPR issues surrounding LTE and WiMAX, but a new report from analyst firm Maravedis should shake things up a bit. The firm has recognized that ADC has some pretty important OFDMA patents. In fact, they are a foundation to LTE and WiMAX.
More details on Maravedis' report are at http://www.maravedis-bwa.com/PressRelease-IPR-Report-2nd.html and the report can be purchased from the firm's website. - Hyung
