Google Nexus One Hands-On, Video, and Impressions
wkurzius writes "Engadget has gotten their hands on a Nexus One and have put their first impressions up for the world to see, including whether or not they think it's the 'be-all-end-all Android phone / iPhone eviscerator.' Their opinion? 'Not really.'"
T-Mobile and ATT operate on different 3G frequencies. Supporting all frequencies would be prohibitively expensive.
Right now, in the USA, there's only one provider (T-Mobile) willing to discount your service if you decline the hardware subsidy. If you want to use anybody else, you pay the same rate even if you decline the upfront money.
Either T-Mobile subscriptions will go through the roof, or we've got proof that the public just doesn't care. People with money seldom understand math, see also: Las Vegas.
In Q3 2009 Nokia sold 16.16 million smart phones. Apple sold 7.04 million.
Apple's market share is certainly growing, but in the world of cell phones, they don't come much larger than Nokia.
Agreed, I have a Samsung Galaxy (which has an AMOLED screen), and indoors it looks amazing, way better than my friends' iPhones' screens. Introduce direct sunlight though, and you're looking at a dull, dark-grey mess.
Admit it. You post strawman arguments as AC so you get modded Insightful for refuting them, rather than Troll
So you can buy a Nexus One for $530 and pick up a data SIM for $29 a month. You get unlimited voice, unlimited SMS. I think the data SIM is capped at 5 gigs/month....which at 4 minutes/megabyte comes to thousands of 'minutes' a month. 5 gig is a little sparse for watching youtube videos, but more than adequate for finding information and checking maps.
2 year cost comes to $1,226. Iphone 3G two year cost is $1,975. Pretty substantial savings.
I would guess that google voice is/will be a ton more flexible than other voice providers...can probably do VoIP using wifi whenever you are near a hotspot. Can most likely auto-forward to a home VOIP system whenever you are at home or the phone is turned off. If you have wireless internet at home and at work (who doesn't?), that basically means unlimited everything whenever you are there.
Better display and better hardware than the iphone as well.
To be honest, this sounds like a winner. This smartphone can do many of the tasks of a real PC, yet the 2 year cost is about what you'd pay on the cheapest plan offered by a major wireless provider in the United States.
I doubt that the antenna is the actual problem. From what I remember and it has been a long time 20 years since I did any serious antenna design. You actually need longer antennas for lower frequencies eg 1/2 the wavelength for a dipole and 1/4 for a whip antenna. So the phone antenna can be quite small. Similarly I would be surprise if you couldn't make a fairly broad band antenna at for a mobile. The biggest problem with broadband antennas is impedance mismatching and hence VSWR problems mainly for TX. As you move up the frequency a given antenna can generally operate over a wider band more easily because the wavelength difference between the antenna length and the TX frequency becomes for a given TX band. A 20MHz (capital M for Mega not small for milli) TX band at 100 MHz will give you ~ a 20% variance in wavelength which is larger than the wavelength variation from 1.7 GHz to 2GHz.
Having said that I haven't done any RF design for phones so there may be some gotchas antenna wise that I am not aware of but I suspect the problem if it is a space problem may come from other front end requirements such as the high Q crystal filters, diplexer if they use one, and power amp (depending on design) but I am only guessing. Certainly there are lots of small quad band phones that seem to have solved this problem. Expense is another factor.
