I suppose a good deal of common sense (if not scepticism) is needed.
Just to add a thought on each:
- WiMAX: in this release it is revealed that the range is limited to just 0.75-1.00 miles when indoor-coverage is needed to deliver 5 Mbps. Remember that originally, WiMAX was supposed to deliver up to 120 Mbps over a distance of up to 50 km?
- xMax: I was a little puzzled over the Frost & Sullivan award last week. That seems quite premature, as xMax is far from both technical and commercial reality (see this article): "But is it stretching the rules of economics, or those of physics?" The company behind the 'Flash Signal' technology, xG technologies, puts forward Prof Stuart Schwartz. But the article quotes Prof Ben Friedlander, who dismisses the technology. Who should we believe? Now, Frost & Sullivan seems to add some weight to the xG/xMax side, but the article delicately reminds us of a similar award in 2004 for Gaiacomm ("transmit a signal of any strength to all parts of the planet up to and including inner space and outer space"), which is dormant now. Lastly, the fact that Stuart Schwartz held an interest in xG must not be overlooked (check out this paper from last September, prior to the IPO).
