Cell Tower radiation, how does it work?

When you read research about the dangers of radio signals from cellphones and cell towers, most of the research focus on investigating whether radio signals from cellphones are dangerous, not much is said about whether the signals from cell towers are dangerous.

But it is not uncommon for new cell tower construction to be delayed because of perceived fears of harmful radiation to neighbors.

Why is it that so much controversy still accompany positioning of cell towers when almost everybody today own a cellphone or smartphone? You rarely see anybody complaining about somebody using his or her cellphone in the vicinity of others, at least not because of radiation fears.

In order to understand why radiation from cell towers rarely raise any alarms in scientific studies you need a basic understanding of how cellphone networks work and how radio signals travel through the air.

Entrepreneurs, it takes a village...

Today Bob Dorf delivered some harsh but important words for budding entrepreneurs working on their product in seclusion. His main point was that by not involving others, for example possible customers/users, early in the development process, you do not know for a fact that you are solving a problem that needs solving. Or in a way that potential users find attractive. In essence, what Bob is saying is that you are willingly forgoing a lot of knowledge, either because you are worried to let the secret out, or to actually test your idea and have it fail.

No success for NFC payments without Apple

When Apple recently launched its iPhone5 without built-in NFC capabilities, it was in effect pushing NFC payments at least another year into the future.

As I have said in the past, I don't think NFC payments will become a success mainly because I think the problem can be solved in a better way through an app that would require no hardware.

T-Mobile, this is what you have been waiting for!

This week, Time Warner Cable announced that they are about to get rid of its 7.8% stake in Clearwire. The reason for this deal appears to be that the Clearwire stake represents somewhat of a conflict of interest when Time Warner Cable now are cooperating with Verizon on their AWS deal and acting as a reseller for Verizon.

This deal could not have come at a better time for T-Mobile.

Did Nokia get a lucky break with the iPhone5?

When Apple yesterday launched the highly anticipated iPhone5 it felt like a lot of observers in unison went "meh". Not that anyone is disputing Apples claim that this is the greatest iPhone yet or that it will probably sell millions and millions. But we had expected more from Apple.

How could EU lose out on LTE for iPhone5?

When Apple launched the new iPhone5 yesterday, most observers, including myself, were convinced that the new phone would launch with global LTE silicon inside. I became even more certain of this when Nokia Lumia 920 launched just a week before with a chipset compatible with most LTE bands globally.

Somehow Apple, and so far for unknown reasons, managed to miss out on LTE for a large portion of the world, again.

Facebook came, saw and conquered Wall Street

There has been a lot of talk about the declining stock price of Facebook since its IPO and much doom and gloom has been written about the company and its founder, Mark Zuckerberg.

Amid all this talk about disaster IPO, one tiny issue has been forgotten. It was a great IPO for Facebook!
