Clearwire at 4G World today reported that the first results of its LTE-based 4G trials provided extremely high speeds. Using a full 20x20MHz frequency range, it reached 90Mbps for downloads and about 30Mbps for uploads. The conditions were ideal, with an empty network, but were "massively different" compared to 4G over WiMAX and higher than the estimated 70Mbps, Clearwire's chief commercial officer Mike Sievert said with Fierce in attendance.
