Personally I like useing cabling better but I do have a wireless router I use as a switch when I need to extent my network I plug it into one of 10Base-T jacks and then I un-plug it when I am done. Here in Calgary their are about 75 wireless networks available from my living room.
shut them off when not in use ?

OTTAWA - An Ontario private school has removed its wireless Internet system due to potential health concerns associated to it.

Pretty River Academy, located north of Toronto in Collingwood, is a private kindergarten to Grade 12 school with just under 150 students. Officials have switched to a hard-wire Internet system.

In May, the World Health Organization's International Agency for Research on Cancer reclassified radio frequency emitted by wireless devices as possibly carcinogenic.

The school's principal Roberta Murray Hirst said the new system was fairly effortless to install and the school wanted to choose the safest Internet option.

Dr. Magda Havas, who studies environmental contaminants at Trent University, hopes other schools will move towards this model.

"This is a much better way of connecting kids to the Internet, it's not nearly as dangerous as wireless," Havas said.

There have been no short or long term studies done on the impact of Wi-Fi, though some researchers believe children may absorb more radiation than adults.

Students and teachers at a number of Canadian schools have raised concerns about dizziness, headaches and other side effects they believed are linked to wireless exposure.

The Elementary Teachers' Federation of Ontario is set to review wireless Internet in schools after educators raised health concerns and voted on the issue during the summer.

However, Health Canada insists Wi-Fi is not a big cause for concern.

"As long as RF energy levels remain below Health Canada's RF safety guidelines, current scientific evidence supports the assertion that RF energy emissions from Wi-Fi devices are not harmful," the department said in a statement Thursday.

The good doctor can issue aluminum hats. She sells them on her web site! :rofl:

Interesting, as the local school district is doing away with teacher's printer (and attendant ink/toner problems/costs) in every classroom and teachers will now print to copier/printer in office via Wi-Fi. Only problem is, not all of the schools have Wi-Fi. Including the "state-of-the-art" 1 year old, with ground source heating and cooling, solar panels, AND ECO-FRIENDLY, school that my daughter teaches in. You'd think they would have put in a wired network!

We won't even talk about the fact that all printing is to be PDF and the conversion software purchased is slow, hard-to-use, and generally clunky.

Oh yeah, and how about when the printer gets 'hacked' and starts printing..... PORN PDF!

John, we'll have to find you another past time. :rofl:

Serious though, whether it's wired or not, that type of thing could happen.

Dave, I wonder who is going to be responsible for making sure the ONE AND ONLY printer in the whole school is operational and has plenty of paper and ink/toner. The more I think about this, the less I think of the idea. Glad it's not my school district. (Note to self, Call Hoke County Schools IT dept Monday and warn them of the pitfalls BEFORE it's too late.)

WOW that would have cut into my summer work. We wired 6 schools for wireless. All the schools in my town are wired for wireless.

Good gracious. The biggest source of radiation is the sun, if WHO (notice the anacronym) have thier way will that be turned off as well?

Sounds strange, "We wired 6 schools for wireless"

Yea its a good question, who is going to maintain that 1 printer for all.

1 Step foward 2 steps back

FdTech, I thought so, too. Wouldn't "wired 6 schools for wireless" be an 'oxymoron'? Like "Jumbo Shrimp", and "military intelligence".

What about everybodies cell phones? Do they lock them up far outside the building in a shielded shed?

-Hal

I don't think they alow cell phones in schools. In hospitals you got to shut off your cell phone but I did see doctors using wi-fi in hospitals.

since their is some controversy over wireless in schools with little kids it should be avoided if posible


:read:

Teachers and administrators don't have cell phones? The policy for kids is so that they don't use them during class and disrupt it. Nothing else.

Everybody talks about hospitals requiring you to shut off your cell. I have never seen one that does, at least in maybe 15 years. The reason was that they were afraid the phones would interfere with the telemetry and other equipment such as imaging. Hospitals today hopefully have upgraded their equipment since than and cell phones are no longer a problem because the equipment is designed to tolerate them. Heck, I don't even turn my phone off that's hanging on my belt clip when I get a nuclear stress test or ultrasound test. Patients all use them instead of paying for the hospital room land line.

The controversy is BS. That kind of stuff has been going on for years and every time somebody comes up with something like that somebody else disproves it as vodoo science.

You can't possibly single out WiFi without considering cell phones that are constantly held millimeters from your brain and are thousands of times more powerful.

As a matter of fact in the US it is illegal for anybody to object to a cell site location on the basis health.

Over the past couple of years, my dad has been in Intensive Care a few times. The hospitals required us to switch off our cell phones when going in to visit.

The rules for the Step Down units & general rooms tend to be less restrictive, but vary from hospital to hospital.

Well, I can only attest to when I was in ICU but then I wasn't in any mood to use my phone so I don't know. I don't believe my visitors had to turn them off though. But like you said, it varies from hospital to hospital but the point is that if they are prohibited it's because of potential interference issues, certainly not because they are a health risk.

-Hal

Maybe we will evolve, and grow big tumors on the side of our head to hold our cell phones?

Either that or our brains turn into cell phones.

Let's all spend OPM* and chase a "possible" issues.


*Other People's Money

Are these the same folks that said plain old homogenized, pasteurized cow's milk was bad for adults, and then said 'oops, our bad, it's ok'?

This is a purely emotional issue and as such does no warrant the spending of public money. However that has never stopped politicians before...

How about broken ankles from tripping over the LAN cables?

Health Canada won't issue Health Warning yet!

For personal use I like to plug into the internet because its faster than wireless ...ect

"Faster than Wirelesss"

FOUND ANOTHER ARTICLE AGAINST WIFI
https://cnews.canoe.ca/CNEWS/Politics/2011/10/06/18789031.html
The Government should test the wifi on themselves first but they use cabling?
Never underestimate the power of stupid government people in large numbers

Scientists say radiation emitted by cellphones is substantially higher, however, and more focused on the brain.

I just said that. Glad those scientists agree with me.

-Hal

Everybody is using one...I use cell phones but I don't like to be permanately attached to one.

What about Microwave ovens? Everyone has one in their home. I bet many schools do too... are they worried about this at all? The Microwave Ovens operate at 2.45GHz .. same frequency as WiFi... (IMS band) and yes they do all leak some RF. Most everyone has WiFi at home.. or the next door neighbor does. You can't escape WiFi these days... I love how these people think the reason the kids are dizzy is because of the WiFi.

not to dwell on old topic, but this recent one might be interesting

:thumb:

That was very interesting !

lest see. Cell phones are about 500mw-700mw at 800Mhz, 900mhz 1.8Ghz and 1.9Ghz for a quad band phone. Wifi AP's are about 100mw at 2.4Ghz and or 5.8GHz. Laptops have lower power transmitters and can be as small as 23 mw. Bluetooth is in the 2.4Ghz band too not sure on transmit power.

The higher you go in FQ the more power you need to cover the same distance.(inverse square law) Sure 2.4 GHz is the frequency of a Microwave, but those are shielded somewhat and the power can range anywhere from 800 Watts to 1500 Watts. Also from a Microwave the power is spashed over a few hundred MHz of the entire 2.4GHz spectrum instead of a narrow channel about 20 mhz for wifi.
Frankly I'd worry more about the devices we push against Our heads which are at a higher power for a longer duration and not protected by the water in our flesh instaed of in a petri dish protected by nothing.

I wonder if they did the sperm test in an RF shileded envionment.
