The cell phone blocker uses three methods to interrupt the communication of mobile phones. Some are allowed in some public places like theaters or schools. To be eligible, a vice may not cause interference outside those covered by the scheme. Similarly, should comply with the regulations applicable to emergency calls. More importantly, this type of equipment shall only operate in frequency bands identified, without affecting other types of wireless communications (DECT phone, …), and Taik-talkie that could affect security in the building, for example , or block an emergency call could be for a very important or sensitive situation.
The polluter, which is the technique of interference from the most extreme. This case relatively little intelligence is constantly emitting a false signal on the same frequency as that of telephone relays. No calls, incoming or outgoing, are allowed to be in the range of the device. A range of 5-1 000 m, less aggressive techniques is based at the relays, allowing the phone to pass an emergency call, but prohibits incoming calls. Other systems, finally, blocking communication between a telephone relay operator by issuing a false signal, whatever the meaning of the communication is, but only after detecting a call.
Some institutions are already equipped with such systems.Sold $ 150 (unlicensed products) to more than $ 1500, cash in the market blur the GSM standards, MASC, TDMA, PCS, but UMTS and Wi-Fi. The scope of these devices vary according to their power, from five meters and can reach over 1,000 meters (usually for military applications).
Three techniques to disrupt communications
- Air Pollution: The area is covered by a type of gag polluter. All forms of communication from a mobile phone is impossible. In general, these devices, we can not guarantee that interference will not overflow outside the area in question.
- The management of interference with emergency calls, the chuck is equipped with a repeater, which recognizes that age is to call emergency services. The emergency call is allowed, but not to others, whether incoming or outgoing. The other radio signals (DECT, Wi-Fi, etc.) Do not interfere.
- Interference detection after the call: The gag is activated only when it detects a call (incoming or outgoing) and is not allowed in the area it covers. It then sends a signal type BCCH (channel of information between the cell and the mobile operator), so that cuts base station communication. The other radio signals are not interrupted.
So it is obvious that the second method is the most reliable and convenient for public use.

Have you ever seen the coolest solar charger KiwiChoice U-Powered Solar Battery? You can charge your iPhone or iPod Touch anywhere, charge the device itself using the sun’s rays, and charge any other devices at the same time as others. It’s useful in the best ways, and the design makes it a real winner!
It’s a real bummer when your battery dies when you’re traveling. That’s why external batteries were created for use when you have no access to electricity. But those cost up to 60 dollars, and do nothing as close to what the KiwiChoice U-Powered Solar Battery does.
This unique device made my KiwiChoice Inc. is the perfect companion for those moments when you’re battery dies. With a width of a semi-thick phone, this device does things far beyond what those average batteries do.
Instead of charging just one device at a time, the KiwiChoice U-Powered Solar Battery can charge up to three. The thickness of the device is because of the three charging units, that once spread, look like a fan or a propeller you would see on a biplane.
So how do you charge? You can use your own cables to insert into a specific spot on the three charging units, or you can use one of the eleven tips that are provided when the product is purchased. These make the KiwiChoice compatible with pretty much every type of mobile device. Here’s a list of the compatible items made possible with the 11 tips: Nokia, Samsung, LG, Palm, Blackberry, iPhone, iPod, Motorola, Sony, Bluetooth, GPS, digital cameras, PSP, ebook, Nintendo DS, kindle, etc.
Also included in the mix of useful items are the car charger and the wall charger which can be used to charge the KiwiChoice. The device also has an LED.
Not only can the KiwiChoice be charged with USB compatible chargers, but it also is charged by the sun using the many solar panels on every of the three charging units. Of course, charging with the sun takes more sun than with a wall charger or computer, so you might take that way, but think of the environment will ya?
What’s extremely cool is that the charge of the device lasts for tons of time. On the site, they claim that it can last up to 6 months. That sounds like a big number, but I wouldn’t put it past this device!
There are some magnets located on the body of the KiwiChoice which enables you to stick it to a magnetic service. This helps as if there’s something magnetic wherever you are charging your devices, you can ensure that the whole device won’t slip and fall.
