When does blocking a signal help your cell phone connection?

Did you know that 80 percent of all mobile telephone usage is indoors? I was surprised when I first heard this, but then I thought about it – my mobile phone has replaced my landline, and even in my office I typically take most calls on my cell phone. This fact, along with a generally more “noisy” radio frequency (RF) environment, has led to massive growth in the use of in-building wireless (IBW) systems.

How would you fare if a blast event happened near your building or office?

For a truly terrifying read one day, just type "recent terror bombings" into your search engine and see what pops up. There are more terror plots thwarted or perpetrated every week than anyone could possible keep up with, aside from those security professionals whose job it is to focus on nothing else. An unfortunate fact of life that we now have become accustomed to in modern society is that too many people across an astonishingly wide variety of the political spectrum are willing to take matters into their own hands and commit violence. As uncomfortable as it is to think about, we must all face the reality that there is some possibility, albeit remote, that we could be the unwitting target of a terror attack or the collateral damage of another target. While the probability of being involved in such an attack is admittedly low, the potential downside is extraordinarily high. Furthermore, if you operate a business in a high traffic area, or live in a major city, the odds of your building being subject to such an attack might not be that low, as unsettling as that may be to think about.

Ways to Reduce Summer Energy Cost in Your Building

Summer is coming, and together with backyard cookouts, the lazy drone of lawnmowers, and baseball comes the inexorable march of the summer sun. Hotter and longer days translate into more time with your home or office baking in the sun, with all its attendant damage to furniture, paint, carpets, upholstery -- basically, anything the sun's rays touch. Life on earth would not exist without the sun, and it is an important source of vitamin D3, but it is also a mutagen, or a "physical or chemical agent that changes the genetic material, usually DNA, of an organism." Anything strong enough to change your DNA can certainly drive up your energy bill and damage the inside of your office!

How to prevent RF data loss at your office

What is RF data loss? RF stands for radio frequency, and RF data loss is a concern wherever wireless technology is used. WiFi networks, Bluetooth technology, and cell phones all use radio waves to transmit data. Those radio waves travel through open air, which is fine provided that the only people in range of the RF signal are those who should have access to it. However, if you've ever stayed in a city hotel, or lived in a city apartment building, or worked in an office park, a quick scan of local networks on your smartphone will produce 10-20 networks surrounding any particular location in the building at any given time. Even a typical suburban home will have at least two or three networks bouncing around its walls -- a quick check of my own smartphone as I type this actually came up with five nearby here in suburbia!

Should I use Low-E glass or window films to block heat?

If you have kids and they've ever left crayons in the back seat of the car on a hot summer's day, you have had an involuntary crash course on the power of the sun. Yet even without adding a substance with such a low melting point as a crayon to the mix, the sun can easily damage girl_playing.jpgyour car's upholstery or that of any furniture in your house or office if directly exposed to the sun. Just take a look at the damage done to the paint of any car parked outside for a year or two and you'll get a good idea of how powerful the sun can be -- certainly the upholstery or leather on your favorite couch or easy chair doesn't stand a chance. In any office building, hotel, or restaurant, the sun can damage carpetting, furniture, and even walls! Particularly for those of us who live south of the Mason-Dixon line, the sun's power is to be taken extremely seriously.

How to protect the boardroom monitors from prying eyes

Have you ever been to a high-security military or intelligence office building? Typically, they don't have any windows, and there is a good reason for this -- they do not want to be susceptible to prying eyes from the outside. In today's corporate environment, the need to protect data from increasingly more effective corporate espionage techniques is a major concern for chief information security officers (CISOs) and other property owners, as well as for the architects and general contractors who create modern office buildings. Even putting aside espionage concerns, open plan offices with glass walls promote transparency and collaboration but also make data privacy a major problem.

How to Manage Glare in your Office

Are the following situations all too familiar to you in your office setting? During the morning meeting half of the room can't see because the sun is creating a glare on their computer screens. At lunchtime the board room presentation is interrupted as you constantly adjust the brightness on the projection to combat the sun's light. While the sunset is beautiful, you are forced to work in yet another position as the office is flooded with a bright light. Throughout the day different employees complain that the glare is making it hard for them to see, giving them a headache, or otherwise reducing productivity. If you are nodding your head at the familiarity of the above office encounters, then it is time that you consider installing a window film.

What is Radio Frequency (RF) Attenuation and How Can It Affect Your Life?

Merriam-Webster defines the verb attenuate as “to lessen the amount, force, magnitude, or value of, to weaken.” For radio frequencies or light waves, this refers to the way in which the strength of waves lessens while going through open air, walls, windows, the human body, and other surroundings. For our convenience, modern wifi networks, mobile phone signals, and Bluetooth connections (all of which are types of radio waves) are generally strong enough to reach through the walls of our homes and workplaces and thus are strong enough for us to remain connected even outside of buildings.
