Wireless Broadband's Big Appetites

It is good news that the bad news is not all that bad. There will not be a spectrum crunch. But there is one now. The possibilities have not been realized.

The Spectrum Crunch that Never Really Was
Cisco estimates that mobile data traffic will grow by a factor of 18 by 2016, and Bell Labs predicts it will increase by a factor of 25..... when wireless networks are overloaded, the real culprit may be inefficient use of existing spectrum rather than a fundamental shortage. ..... "We don’t have a spectrum crunch so much as we have a spectrum policy crunch .... The so-called ‘spectrum crunch’ really reflects artificial spectrum scarcity" ..... “The challenge now is to extend those proven successes to enable wider-area broadband access using other underutilized portions of the spectrum.” ... such strategies could increase wireless capacity by thousands of times...... half the new demand through 2015 would be handled by small cells—Wi-Fi plus cells handling frequencies used by 3G and 4G networks ...... it might be possible to increase capacity tenfold even without spectrum sharing. ..... rigid regulations don’t allow the use of flexible new technologies like cognitive radio ...... “Right now, we have a 15- to 20-year backlog of new technologies and architectures, including sharing and small cells, which can take us a long way into the future.”

Wi-Fi, Tablets And Smartphones

iPad 3G and iPad Wi-FiiPad 3G and iPad Wi-Fi (Photo credit: Yutaka Tsutano)The Next Web: New Wi-Fi roaming initiative could soon allow your smart device to connect to hotspots automatically
... could see billions of smartphone and tablet owners effortlessly switch between mobile and Wi-Fi networks, without the hassle of locating hotspot hosts and keying in passwords....... a technical and commercial framework for Wi-Fi roaming, which will use a device’s SIM card to authenticate a device on a Wi-Fi hotspot without any input from the user ...... the initiative could offload mobile data to a residential or business-owned wireless network
And while you are at it, why not also extend this to laptops? Smartphones make sense, tablets make sense. But if you keep the laptop out, the iPad will have even more of a field day.

Republic Wireless, Galaxy Nexus And Tardiness

I have a laptop I bought a few months back for 330 dollars after the rebate. I think I want a $79 Kindle to borrow books from the New York Public Library. And I think I have decided on Republic Wireless to be my first smartphone. And that is it. That will be enough gadgets. I am a Dell, Walmart kind of guy.

They said they will be out. But then you go to their website and they say sorry, get in line, we will email you when we have more. So no soup for you this year.



No Republic Wireless phone in sight. $19 a month is cheaper than even the prepaid basic phones. For me it is the wifi part that gets me. A smartphone is a small computer. It needs to be running on wifi. What I would have really liked is a Galaxy Nexus on the Republic Wireless network. But if it is between the phone and the network I am going for the network. Only the line is so long. Take that iPhone.

Why don't they just manufacture more phones? I mean, if they are making money when they sell phones. Why not just make more of them and make more money?

Galaxy Nexus Has Competition
