All About Cordless Telephone

A wireless telephone (telefone sem fio) is an electronic telephone that comprises of a wireless handset and a base unit. Communication is carried out between the handset and the base utilizing radio waves. The wireless handset could be operated only within a set range from its base unit. The range of operation is generally within 100 meters. The base unit needs electricity to power it. Batteries are used to power the wireless handset. Placing the cordless handset in the cradle in the base unit recharges these batteries. A period of 12 to 24 hours is needed for recharging the batteries.

With features like cell handover, data transfer and international roaming (on a limited scale), the as soon as clear-cut line between mobile telephones and cordless telephones (telefone sem fio) has now been blended by the contemporary cordless telephone standards.

Frequency bands have been assigned in every country for cordless telephones (telefone sem fio). Advertisements by producers claiming that there is an improvement in audio range and quality with greater frequency are a typical sight. But that is not the case. Really, higher frequencies have been seen to demonstrate worse distribution in ideal case. There is also a tendency for the path loss to improve with greater frequencies. Locally diverse factors such as antenna quality, signal strength, the modulation technique becoming used and interference are more influential than other elements.

With Landline telephones working on a bandwidth of about three.6 kHz (a little fraction of the frequency that a human ear can interpret), the transport of audio is carried out with an audio quality that’s just enough for the parties to communicate one another. Because of this restriction in the style of the phone system itself, it isn’t possible to enhance the audio quality beyond a specific limit in cordless telephones.

Most of the good-quality cordless telephones (telefone sem fio) try transferring the audio signal with lowest possible interference and greatest possible range. Even the very best of the cordless telephones fail to match the audio quality that a top quality phone wired to a great telephone line provides.

Sidetone (echo of voice heard in the speaker of the receiver), disturbing constant background noise that’s because of the cordless program, and inability to obtain a full frequency response that’s available in a wired phone are few of the reasons for a not-so-good audio quality. Rare exceptions, clearly, always exist that sound incredibly similar to a wired telephone. However even these are regarded as as `fluke` by most industry standards.

Higher frequency is now being used in other house goods like the microwave oven, Baby monitor, Bluetooth, wireless LAN, etc. Thus, cordless telephones (telefone sem fio) utilizing greater frequency may face interference from signals from these devices.

Eavesdropping is really a constant security hazard for analog telephones. Any one with a radio scanner and within range can pick up these signals and listen to conversations. Modern digital technology is therefore being utilized to deal with this kind of illegal access.

DSS (Digital Spread Spectrum) makes use of frequency hopping, i.e. dispersing up of audio signal over a wider range in a pseudorandom fashion. DSS signal sounds like noise bursts to a radio scanner or any other analog receiver. This signal makes sense only to that base unit which has the same pseudorandom number generator as the cordless handset. Every time the cordless handset is returned to its cradle, a new distinctive generator is chosen from thousands of choices.

DSS generates a signal spread that leads to a kind of redundancy, which gives rise to improved signal-to-noise ratio. Additionally, it leads to increase in signal range and decreases interference susceptibility. It’s easier to make use of this kind of wide-bandwidth security option with higher frequency.

What Is Satellite Radio Technology?

Satellite radio technology is the equivalent of cable or satellite television and it is certainly here to stay. There are several reasons for this: the quality of the broadcasts is higher, the quality of the apparatus’s reception is higher and the general coverage of the station, that is to say the so-called satellite’s footprint is far greater too.

This has the effect that if you drive long distances, you will be able to stick with the same station without having to look for a new one every forty or fifty miles as you have to do with AM or FM radio stations.

In order to reach this quality, the recording and playback speed needs to be around the 384 kbps level. The music tracks are catalogued in a similar way to the MP3 system, which uses names called ID3 tags.

Each station on satellite radio attempts to establish its own identity. A music station may try this by playing music only of one type or from only one period or decade. This means that you may get a satellite radio station called 1970′s Punk music or Twentieth Century Classical Music.

On some channels, the music controller or disc jockey will choose, say, fifty minutes worth of music, will listen to it in order to ascertain that the quality and the order are correct and then let the computer play it over the airwaves. This allows ten minutes every hour for the news and then the programme can be repeated automatically.

Satellite transmission uses digital recordings and each station is encoded on a different frequency. Similarly, each decoder, say, in your car or your home has to recognize and decode each channel separately as well. This coding and decoding is done extremely quickly, in fact in what is called ‘real time’.

The resulting binary or digital code is then translated into analogue signals so that your speakers can reproduce it. This process creates sound which is just about of CD quality.

The broadcasting satellites are in a geo-static orbit at 23,000 miles above the Earth and have a large footprint which is the name given to the region of ground that is capable of receiving their broadcasts.

In America, for instance, the two regions concentrated on at first were the densely populated east and west coasts in order to maximize potential revenue. One satellite would be incapable of covering the entirety of the United States in that orbit.

In order to receive satellite transmissions, you will have to use a special antenna on your decoder. This antenna must be capable of receiving L-band transmissions for it to be of use.

These new antennas are a big improvement on the satellite dishes (equivalent to those used for satellite TV) that one used to have to have in order to take advantage of satellite radio technology

Xperia Play : An Impressive Phone

The Xperia Play is the new PlayStation phone from Sony Ericsson. It’s hotly anticipated and there’s a lot of pressure on it to perform. Does the phone live up to the hype? Well, first impressions are quite good. The fact it’s a gaming phone does add a bit of extra weight to the device, but this is more than manageable. There’s a good Bravia engine powering it and the screen is a good size. The phone is attractive and looks similar to other Android devices, which is no bad thing.

The phone’s gadgetry is also pretty good and does what you’d expect. There are only a couple of issues: the dual function power button and lock switch is a bit hard to access with the slide out keyboard and while the headphone port near the top of the phone is good, if you use it for a long period of time, the location means the wires do get in the way. However, while the phone is chunky, it isn’t massive, and the MicroUSB charger port does everything it’s meant to.

There’s some great hardware with this phone, including the single core 1GHz next-generation Snapdragon processor, which offers good speeds. This is more than adequate for powering the PS1 games currently available. However, if the games get more complicated over time, this could become a bit of an issue and the phone might benefit from a dual core processor instead, although this currently isn’t a problem based on the games available. Also, the Gingerbread Android 2.3 system is one of the phone’s positive points.

The visuals on the phone are really good, too, with a pretty decent 5.1MP camera. Also, Sony suggests that the phone can run games at 60fps – if it lives up to that, games fans are sure to be very happy. The screen is good too, which is obviously really important on a gaming phone. As mentioned earlier, the 4 inch screen is very good and the 854×480 pixel resolution does everything it’s supposed to do. Putting the gaming controls on a slide out feature under the screen was also smart.

Lastly, we come to the games. The controls for this are very good, with the trackpads making a very good joystick substitute. Also, the shoulder buttons and touch sensitive pads are very comfortable to use, which is good. The phone has access to the PlayStation suite games store, which suggests the games will be improving all the time. This is important as if the games fail, so does the phone. As it stands, though, as well as being a good cell phone, the Xperia Play also has fantastic gaming potential.
