No, this is not about getting rid of cell phones in an effort to fight terrorism. Cell phones are extremely valuable and can be used to help citizens defend themselves against attacks. We need cell phones.
.The concern is about cell phones are sometimes used by terrorists and this has an impact on the rights and privileges of all of us.
It was reported on television that there is a suspect in the Boston marathon bombings. It was said that cell phone records played a part in identifying the suspect. This implies that in the future cell phone records again are going to be used to identify possible terrorists.
A while back there was a proposal all to ban cell phones in New York during the terrorist activity. Of course, to be effective, you have to ban the use of self phones before the terrorist attack. So that idea went nowhere.
Don’t be surprised if in the future law enforcement authorities are going to do more with cell phone tracking and cell phone logging. So you have been warned, be careful about what you say over the cell phone.
Everybody likes a good joke. But some kinds of jokes and not very funny. Even jokes about bombings or murderers and things like that are not very funny if the police are listening to you. And for that matter, do you want somebody to be eased dropping in on your sexually explicit conversations with a certain person? There are some things that are said in person than over a cell phone. Avoid saying anything over a cell phone that you want private.

The problem with using Wi-Fi.
Do you have problems using Wi-Fi with your personal computer or laptop? Some do, many are very satisfied with the way it is. You have to buy new equipment in order to improve your Wi-Fi connection?
This post is loosely based on an article I read from Cisco networks about difficulties people have with Wi-Fi systems at home and in small business locations.
Some personal computer users come to the conclusion that somebody is causing interference to their local Wi-Fi network and the need to buy more powerful and more modern equipment to combat the interference. Is this true? Is that the way to solve the problem? The answer is no. Here’s why.
Most, if not all, harmful interference to a Wi-Fi connection comes from devices that are not really true Wi-Fi devices. In this context, let’s define a Wi-Fi device has some adapter, router, laptop, tablet or smart phone that conforms to the established standards called 802.11 and published elsewhere. These standards specify specific protocols that are to be used as well as power levels and interference considerations. In general, using higher power is not a recommended solution to the problem
because all of these devices must use the same protocol, it would be unusual for one device to an affair with another unless that was the explicit design of the user. In other words, deliberate jamming. Deliberate jamming is either unlawful or only allowed in limited areas, such as theaters were a live performance is underway. A jammer in such a place would prevent people from copying the music from a copyrighted performance and transmitting it beyond the theater. But that is rare.
The more frequent cause of interference to your local Wi-Fi network comes from devices that are not really part of the 802.11 protocol standard. Specifically, microwave ovens and fluorescent lights . Microwave ovens can generate broadband and noise over the entire spectrum used by Wi-Fi devices. So changing your channel number does little or nothing to reduce the interference coming from a microwave oven. Furthermore, the microwave oven only causes sporadic interference while it is actually running. So it’s difficult to know if it is the microwave oven publisher in the same room with it and you can actually watch it cycle on and off.
As for florescent lights, they can generate horrible noise across the entire radio spectrum without any visible or audible indication that something is wrong. In fact, a florescent light can appear to be working perfectly normal while generating large amounts of sporadic noisy interference with radio’s television sets cordless phones and Wi-Fi devices without the owner having any knowledge about the problem.
So what can you do about the microwave oven problem? Asking someone to repair a microwave to reduce the interference level is kind of pointless. The price of microwave ovens are now lowerthan ever and the quality is as good or better than units built many years ago. Also, most trained technicians to not have the equipment it takes to determine if a microwave oven is causing specific interference to the Wi-Fi band.
What about directional antennas? That is an excellent way to reduce interference if you know where the interference source is located. But if and interference source is very close to either the access point or the personal computer, the antenna doesn’t do much but to amplify both the noise and the desired source.
In many cases interference levels can be reduced by repositioning the router or access point in a better location in your house or office. In general, it should be in a open area where you can have a direct line of sight to the laptop or PC in your office or home. When the wireless signals have to pass through walls or go around metal objects, the signal strength is greatly reduced even when the distance is relatively short.
The best way for reliable connection is simply not to use wireless, if that is possible. A wired connection using Ethernet cable is very reliable and is not subject to the kind of interference that you might experience with a Wi-Fi system.
