CDMA2000 data card and Wifi. How long should I keep it on?

[Nexutix]

I have a data card which operates via CDMA2000 mode for broadband Internet. I have connected it to Asus 3G mobile router which transmits wifi signal for my mobile devices. (home use) This set of devices is near my window and I sit near the window for my work, browsing and pretty much 8hrs a day. (2 feet from it)

As far as I gather from resources, WiFi is pretty much safe. I don't know much about radiation/ANY other effects by CDMA2000.

My question is: Should I keep the data card always connected and ON? Will it have any Health effects on me?

[I will furnish any other details if required. ]

I am a electrical engineer with 18 years of experience and for over a year I studied materials using high-power high frequency radiowaves. CDMA2000 devices operate in the 450MHz to the 2.1GHz range - you didn't mention your CDMA2000 carrier, but assuming it's Verizon your device is either at 850MHz or 1900MHz - probably 850MHz. All RF signaling in this frequency range are nonionizing radioation which means that signals in this range can heat up materials but they don't damage DNA or damage living tissue.

Here's an EPA page on the topic:

and another page:

There is no danger from having this device near you - about the worst thing that could possibly happen is that you might be slightly warmer. But at 2ft with the power output of a CDMA2000 device, there is no danger at all of that. If you think about it, normally a CDMA2000 device operates on a super small battery for the better part of days... how much power can they produce? A microwave oven - which heats food using radiofrequency signals at 2.45GHz usually uses close to 1000W continuously. A cell phone battery has about 2W of energy in it but uses this power supply for days - even weeks for some phones.

Honestly, there is no danger because nonionizing radiation doesn't damage cells and the power output of a CDMA2000 device is very low.

I am grateful for such a detailed response. People make a lot of fuss about all this, upto the level everyone gets paranoid in a thread/comment section.

[Yep, my carrier operates at 822-844 MHz]
