Mobile phones are banned (if not explicitly, at least at the level of common sense) in quiet public places such as restaurants, theaters, cinemas and churches. What if people do not understand the good word and close their phones? Use a jamming device.

Many people can not come off the phone in those places and even use it extensively. If they would be limited to SMS it should be acceptable, but they don't even bother to pass it on silent mode. Jamming devices are widely used in Romania, but in other countries they are popular and we ensure silence in many places.

Jamming devices are devices that block or interrupt radio signals emitted by the phones. These devices have high power and manage to cancel the signal. They are effective even against dual-SIM mobile handset, it "tricked" the area where there is no coverage of any mobile operator. There Jammer, a sophisticated devices that can signal to cancel even Triple-card phones, which are connected simultaneously to the three mobile networks.



Operation frequencies jamming devices are easy to set up and function properly depending on your choice of these frequencies. Mobile-phone frequencies 900 and 1800 MHz to 1900 MHz for Europe and Asia and USA. Distance interference is influenced by the obstacles encountered in the way radio waves, such as walls or hills. Poor equipment interference can do their job within a radius of 9 m in a building, while in an open space can even cover a football field. There are no devices currently succeeding phone jamming signals over a distance greater than 1.6 km.

A jamming contains device electronically speaking, consists of a hub device, transmitting antenna, and power supply circuits. The front panel is usually a potentiometer, where you can choose the frequency of work. Wireless devices and less power, are power by a battery. Powerful devices are powered directly from mains.

Proved useful in avoiding bombings as most bombs were triggered by mobile phones they have been used to shift the official columns to prevent bomb attacks on important persons in the world. Their use has been successful even to jam the communications between criminals and terrorists, in case of attacks. The devices are used in areas with high risk of explosion, because a cell phone can trigger such an event in a high risk area.



Laws concerning the use of jamming devices There are few countries where the use of jamming is perfectly legal. In most countries like the U.S., Britain and Australia, the jamming of mobile phones is prohibited. In the U.S., the law says that such devices may be used only with special permit and license. The sale of these devices it not allowed. Those who do not comply with the regulations are likely to receive a $ 11,000 fine and remain without a jamming device. Sometimes, they go to prison.

Other countries, like France, have such equipment in cinemas, concert halls and other public places. In India they are used in some prisons and parliament. If you are a student in Italy, it might surprise you that during your exam you cannot use your phone as rectors of universities to the idea of blocking the signal of phones so nobody could use the to cheat.

Nokia 8800

Nokia announced the emergence of a new model, a luxury mobile phone category, namely long-awaited successor to the 8xxx range - the Nokia 8800.

Long awaited, the handset is covered with a steel casing with a special sliding mechanism, called the card manufacturer "unique pop-up mechanism".

8800's display is a new appearance of the range Nokia presented on paper 262,000 colors and 208x208 pixels resolution. We hope that the field display to present such, not only on paper.



The device is equipped with a camera objective which can save images up to 800x600, which can record and play videos. It is already easy to understand that the target is so low in marketing strategy reasons. The same limitation of the reasons this strategy meet and Chapter 64 MB internal memory only. Apparently it is enough but as mobile is equipped with MP3 player, 64 MB is not enough for this feature. As well the built-in radio but its independent of internal memory.

This device maker Nokia has launched under the slogan "Nokia 8800 - Art Meets State-of-the-Art". I do not find anything extraordinary in terms of design of this phone and I wonder what his competitors Nokia launches mobile such that it seems that not a big engineering this phone for late 2005.
Other equipment: EDGE, Bluetooth, Java MIDP 2.0, etc. ...

A good thing is that related to the ring tones are played on 64 different voices, Nokia promising a revelation in this regard.

Image quality seems to promise a near flawless manufacturing of furniture, but perhaps the Nokia Vertu calculated here and said that 8800 will not compete with the Vertu cell phones,
One thing is certain: a rare robust Nokia branded mobile!



However this in a very good mobile, despite all its weaknesses it has a very good anti-shock system because of its metal case.

Motorola MOTOROKR Z6m

Maybe Motorola should not have to give up names or model RIZR ROKR favor. Unlike the first ROKR, Z6m supports Windows Media 11 and not iTunes. The phone has a display friendly, with a menu structure completely different from the rest of the Motorola phones. The operating system chosen is the new Motorola OS based on Linux. The terminal looks picture of the RIZR, but is rather a slider than a clamshell, so attractive.



Sony Ericsson K810
Series Cyber Shot camera phone needs a serious lesson from the Walkman series. To compare the K810 with the W880i Walkman series. K810 is massive and lacks the style of the W880i and Cyber-shot interface is not as friendly as Walkman. In other news Xenon flash and auto focus function are fine, but 3.2 mega pixels is too small a number compared to competing mobile facilities. But considering the lens included, we could forgive the lack of several million pixels for a clearer picture.



Nokia E61i
Nokia E61i is a natural evolution of the Nokia E61. Improved a little in each chapter: the keys are rubber, offering greater ease of typing and the terminal is thinner. The model could not be seen "in action" due to bad connections to the network offered in CTIA, so we keep a frenzy for any E62i.



Nokia E90

Nokia E90 is big, very big. The reality is even greater than in pictures and is basically a nice version of the LG Env. There is certainly a terminal that you can pocket, much less to throw in a briefcase or purse. E90, when a phone is closed is ridiculously high, a parody of the candy bar type phone. Open the terminal and you will see large keys (obviously) and a bright and clear screen.It was still a top 10 finish and we can only wonder when we see these beautiful (or less wonderful) terminals on our market already full of models of Sony Ericsson Walkman.



LG VX9400

LG VX9400 - A phone surprisingly easy and slim, without VX9400 mobile TV in your pockets. V Cast Mobile TV phone supporting streaming quality at higher resolutions, making a big step forward in mobile TV. The model has a 1.3 mega pixel camera, Bluetooth, memory extensions and supports EV-DO.



iPhone
iPhone - from Apple mystery phone-fill the top 3 in February, but will have to wait 6 months until the arrival of the phone.



Equipped with 8GB of internal memory, Wi-Fi, support for Google Maps and touch-screen iPhone will be available for $ 599 or 499 if you opt for the 4GB version.

HTC Advantage

Here HTC Advantage X7591, a terminal design at least interesting, even if many of you may be asking "by who was this phone manufactured?" X7591 supports 3G services and includes a locking system based on magnets. Running on Windows Mobile 6 the phone has advanced multimedia features and editing Office of the latter type, all visible on the display and touch screen 5 inch.


Samsung F700

It is strange that I did not find a functional model of F700 in the CTIA 2007 ... Samsung Ultra Smart phone that had a version that goes to their stand, seemed to forget just recently hit and missing their chance to attract visitors. Issue is not necessarily the fact that the phone is not available, what bothers us is that it does not work. This is the iPhone rival that you expect?

Motorola MOTORIZR Z8
The difference between the angle of slide angle's RIZR Z8 and other phones is enormous, but that attention through the artifice of design can be a decisive factor for the popularity of Z8. It has a very "organic" look made by the combination of colors that a display and we are dealing with a high-end, the model includes a QVGA display and HSDPA 3.6 Mbps. Z8 supports micro SDHC cards and is the first step on the sliders in the U.S. market for Motorola.



LG VX8700
LG VX8700 is a new direction in design chapter, but the misery is the only aesthetic or strength. Metal casing is a good choice in combination with reflections of light it produces, or protection against fingerprints. We would still like Verizon Wireless to be more innovative in Chapter structure of the menu. LG VX8700 includes a lot of themes for the phone screen, clear and a reasonable price metal terminal could be a trendsetter even on our market.



Motorola Q q9

Motorola Q Q9 model resembles very much the Q model, so much that you might confuse them very easy, whether you're an expert or a beginner. However the new model is more rounded, making it easier to hold in hand than the "cousin" or. We say that the Q9's keyboard experience was satisfactory and that we look forward to see him it in USA and in Europe too .



Samsung UpStage
Samsung UpStage from Sprint is undoubtedly a thin phone with a design that will intrigue. But we wonder if it will become tiring this flip-phone use because of design or. By incorporating a music player, which already is packed, used on Sprint phones, terminal could even use a new interface to compete in crowded wireless market with music functions.



However UpStage has a chance with downloads of songs that offers the Sprint Store at a price of 0.99 U.S. dollars.

Apple iPhone - iPhone is a cell phone, media player and a wireless communication device announced by Steve Jobs, CEO Apple, Inc.., During his speech at the Macworld Conference & Expo on January 9, 2007. iPhone has support for push email, mobile telephony, SMS, web browsing.
