[citation][nom]booyaah[/nom]Huawei is that big Chinese networking equipment manufacturer. They got called out by several security firms for putting backdoors with static passwords on all their routers and took some major media flak from the U.S. govt recently that no data center should use their products. They might be able to sell some of these in China, but I doubt anywhere else[/citation]
The routers with the backdoor were a cheap entry level model for residential purpose. I doubt that similar products from other companies are much better secured.
I'd take that with a grain of salt because from where I stand (that's in Europe), the U.S. govt seems to have a problem with buying anything that's not american. See the Airbus vs Boeing tanker fiasco. Airbus won the tender two times, with a product that was superior by any mean (economy, performance, capacity, flight instruments,...) but got finally busted in favor of a rather obsolete Boeing design based on the 767 (which was no longer manufacturerd for years already). But we like our F-16 and C-130 fleet though ;-).
In almost every european country, you'll see at least one big networks operator that uses Huwaei antennas/stations for the 4G network. China is what Japan used to be long time ago: copycats eventually becoming mature enough to create their own tech.
