An eager photographer catches the 787 Dreamliner in the buff

It has been a long time coming, but the first Boeing 787 Dreamliner has rolled off the assembly line. Charles Conklin -- an avid aviation enthusiast -- managed to snap some pictures of a fully assembled Dreamliner sans paint.

According to Flightblogger, the official roll-out ceremony for the Dreamliner is on July 8 with the first delivered scheduled to take place in May of next year. The production run of aircraft is completely booked until 2013 at the earliest.

The Dreamliner is the next generation of airliners for Boeing and makes use of composite materials in 50 percent of its body and wings. The use of composite materials has helped Boeing keep the weight down which allows the Dreamliner to be 20 percent more fuel efficient than its closest rivals. Top speed for the aircraft is Mach 0.85.

Business travelers will appreciate the integrated networking capabilities on the Dreamliner. Boeing had initially planned to equip its Dreamliner with wireless networking, but instead decided on a wired networking to save 150 pounds per plane.

As of April, 44 customers have ordered 544 Dreamliners at a cost of $75 billion USD.

Wireless heavier?

Anybody know why wired networking would save weight compared to wireless networking? Common sense would seem to indicate that wireless would weigh less than wired because you would save the weight of all the wires that would have to be run. Is the article saying that wireless was going to be in addition to wired, but then it was decided to go with only a wired network to save weight?

I read on a previous thread that the Wireless is heavier because in order to keep the signal strength low and bandwidth higher, they would need to put access points above almost every set of rows. So more (heavier) wireless equipment would be needed.

That seems like a good explanation. So, in effect, the "wireless" solution would have been 98% "wired" with the last meter or so to the end user being wireless.

They could already have CAT5 run through the aircraft for other features.

The weight might be from shielding required for more sensitive components. I'm sure that these would be shielded even without wireless though, due to other EMI sources.

The higher the altitude the heavier the wireless frequencies are ;)
