4G or not 4G Reblog

4G or not? 

Owners of AT&T's iPhone 4S are a bit confused with the 4G cell signal icon now appearing on their devices after they updated to the new iOS 5.1.

While the AT&T iPhone 4S model runs on the wireless carrier's HSPA+ network, a slightly faster version than 3G, it is not receiving 4G or 4G LTE speeds which are 10 times faster than 3G.

The iPhone 4S does not have the chipset required to access a 4G network. It will run at the same speed before the iOS 5.1 update.

However, AT&T spokeswoman Kelly Starling said "iPhone 4S customers have been getting 4G since day one."

AT&T's company response: "Apple has updated its iOS software to show a 4G network indicator when customers are on AT&T’s 4G network.  Only AT&T’s network lets iPhone 4S download 3 times faster, and only AT&T customers have access to the nation’s largest 4G network covering nearly 250M people."

Confusing? Yes.

While some are calling AT&T and Apple dishonest and manipulative, part of the problem is that the definition of cell signals, known as 2G, 3G, and 4G, is a bit fuzzy.

A 2010 decision by the International Telecommunications Union, an agency of the United Nations that establishes worldwide telecom standards, shows that 4G is an "undefined term" that can be applied to LTE and "evolved 3G technologies."

AT&T andT-Mobile rebranded their HSPA+ networks as 4G.

LTE, which is a true 4G technology, is marketed as 4G LTE.

The new iPad, announced earlier this week, will run on 4G LTE.

C910 Versus C920 (Out of Box Difference)

Unboxing the C920

C920 and C910 Side by Side


My experience with the C910 is that it’s a solid webcam. I haven’t had time to test out the difference between the two or even power up the C920.

The C920 out of box has a bigger lens section. A Better fitting method and it also doesn't have the Blue lights that the C910 would power up when active. (This I guess would remove the blueish hue in low light situations) I personally never had a problem with that though. 

I’ve been asked to do a comparison video but my biggest roadblock is what should I be doing as I do this comparison?

I can’t wait to test it out though.
Performance tests coming up next!

Google Play (20,000 Songs to the Cloud)

Play.Google.Com


At first I was skeptical about what Google Play is.

It looked like a response to Icloud and Itunes as a location to buy and store your digital purchases.

However the more I look at it the more it looks like an evolution as opposed to a response.

I've tried out Spotify, Pandora, Grooveshark and other music streaming service.
I'd dare say that Google isn't doing a streaming service like those listed above.


It's key differences:

1. Web Service : Everything is on the Web Browser, including the music player.
2. Your Music: Up to 20,000 free. More if you pay.
                 To get your songs you can download something called a music manager to sync your songs between your computer and the google cloud.

The Interface : Like I said is within the browser.
It works with my car's on-board music controls and it streams with a slight lag between songs. 



With this said, I think it's a natural progression of cloud computing.
I'll be trying this out a bit more.

Google Play also does streaming Video with what you buy.
