摘要

As someone who has spent more than 20 years in telecom, wireless, and satellite communications, David Helfgott, chief executive officer of phased array antenna manufacturer Phasor, knows technology evolutions can happen quite quickly. Yet it still boggles his mind that barely more than a decade ago, when he worked for SES in the early to mid 2000s, engineers were focused on getting wideband and broadband satellites onto land-moving vehicles - and using the industry equivalent of caveman tactics to do so. "We got a bunch of Radio Frequency (RF) elec- tronics and a big, domed 1.2-meter mechanically steered antenna, and strapped them onto a Hum- vee that we bought on eBay to prove you can get a 5 megabit link on the move," Helfgott recalls with a laugh. "But it was only a proof of concept and not a feasible commercial technical solution, given the weight and very high profile antenna. We needed something better."
