Satellite Radio Technology

By Angela Gymmy

Satellite radio technology is the equivalent of cable or satellite television and it is definitely 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 channel, that is to say the so-called satellite's footprint is far greater as well. This has the effect that if you travel long distances, you will be able to stay with the same channel without having to look for a new one every forty or fifty miles as you have to do with AM or FM radio stations.

Normally, if you are driving on a long journey, you will have to constantly retune your radio as you travel to search for a new station you like as you move from one locality to the next, unless you have tuned into a national station. This switching and tuning that has been a part of life for FM and AM radio listeners really is now becoming a thing of the past.

Terrestrial radio can only work when the signals are strong, so in more rural areas you may not be able to pick up many stations. Satellite radio doesn't have this issue. The signals are transmitted by a satellite and can span across thousands of miles. This means you can listen to the same station from the beginning of your travel all the way through to your destination. You may experience slight fading of the channels if you are in an area that has heavy tree cover, but as soon as you have a clear shot of the sky the station comes back in clearly again.

What you may find different in listening to the radio in this digital age is that there will be less talk time, less intros and just good quality music. The disc jockey does still exist in satellite radio, but he takes more of a back seat. He will prepare the songs for the next hour and compile them onto a format that is like an MP3 to play; long gone are the days where records got stuck or jumped on your favorite show.

Satellite radio reaches millions of subscribers, and they can offer hundreds of stations. Some of the stations may require an upgraded subscription, but you will still have hundreds of stations available. This means you can listen to any type of music you can imagine, or talk radio programs that your local stations may not run.

In America, for instance, the two areas concentrated on at first were the densely populated east and west coasts in order to maximize possible income. 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 broadcasts for it to be of use. These new antennas are a huge improvement on the parabolic dishes (similar to those used for satellite television) that one used to have to have in order to take advantage of satellite radio technology.

How Have Current Wireless Headphones Gotten Better Recently?

By Gunter Fellbaum

Wireless audio is becoming widely used. Numerous consumer products for example wireless headphones are eliminating the cable and also assure greatest freedom of movement. I am going to look at how most current wireless systems can cope with interference from other transmitters and how well they will perform in a real-world scenario.

The growing rise in popularity of wireless consumer systems just like wireless headphones has started to result in issues with a number of products competing for the restricted frequency space. Wireless networks, cordless phones , Bluetooth as well as different devices are eating up the valuable frequency space at 900 MHz and 2.4 Gigahertz. Wireless sound systems have got to ensure reliable real-time transmission within an environment which has a large amount of interference.

FM type sound transmitters are typically the least reliable in terms of tolerating interference because the transmission does not have any mechanism to cope with competing transmitters. Nonetheless, these types of transmitters have a relatively limited bandwidth and switching channels may often avoid interference. Contemporary sound products utilize digital audio transmission and in most cases function at 2.4 Gigahertz. These types of digital transmitters send out a signal which takes up far more frequency space than 900 MHz transmitters and thus have a greater chance of colliding with other transmitters.

Several wireless gadgets like Bluetooth products along with wireless phones incorporate frequency hopping. Therefore merely switching the channel is not going to avoid these frequency hoppers. Audio can be viewed as a real-time protocol. Because of this it has strict demands pertaining to stability. Also, low latency is crucial in lots of applications. For that reason more innovative methods are needed to ensure stability.

One of these strategies is referred to as forward error correction or FEC in short. The transmitter will transmit additional information in addition to the sound data. The receiver uses a formula which uses the extra data. In the event the signal is corrupted during the transmission as a result of interference, the receiver can easily remove the incorrect information and recover the original signal. This technique works if the amount of interference won't rise above a specific limit. FEC is unidirectional. The receiver won't send back any data to the transmitter. Thus it is usually used by products just like radio receivers where the quantity of receivers is big.

An additional approach makes use of bidirectional transmission, i.e. every receiver transmits information back to the transmitter. This method is only practical if the quantity of receivers is small. In addition, it requires a back channel to the transmitter. The information which is broadcast has a checksum. From this checksum the receiver may determine whether any certain packet was received properly and acknowledge. As dropped packets will need to be resent, the transmitter and receivers must store data packets in a buffer. This kind of buffer will cause an audio delay which depends on the buffer size with a bigger buffer improving the robustness of the transmission. Then again a large buffer can result in a large latency which could result in issues with loudspeakers not being synchronized with the movie. Cordless products that use this technique, nonetheless, can only transmit to a restricted number of wireless receivers. Usually the receivers have to be paired to the transmitter. As each receiver also requires transmit functionality, the receivers are more pricey to produce and also use up more power.

Often a frequency channel may become occupied by a different transmitter. Ideally the transmitter is going to recognize this fact and change to another channel. To do so, a number of wireless headphones constantly watch which channels are available to enable them to immediately switch to a clean channel. The clear channel is picked out from a list of channels that has been determined to be clean. One technique that employs this transmission protocol is known as adaptive frequency hopping spread spectrum or AFHSS

Choosing a Wedding Dress to Suit Your Body Type

By John Jones

There are two types of summer wedding dresses. First, there are the formal gowns done in the traditional style. Second, there are those that are simple and less formal but perfect for the kind of wedding held barefoot on the beach in Bali. Each has a place in the choice of options available for brides this year.

Regardless of which type you may be looking for, the upper half of wedding dresses that work best in the warmer months are almost always very lightweight in structure. Long sleeves are exchanged for halter style tops, narrow straps, or cap sleeves.For 2011, we're seeing lots of elegant beading in the dress bodice. Beading catches and refracts light which can cast off a very soft glow in the right setting.

Pear shaped bride: This shape is usually heavier at the bottom and very petite at the top. It is characterized by a wider width of hips and bums and a small waist with petite shoulders. If you are pear shaped, you need a wedding dress that balances your torso to your bust as well as disguises your fuller hips. A perfect style of wedding gown for this body type is an A-line princess wedding dress that draws attention to your petite upper body and flows in a sleek line to slim down your lower half. Another style that suits this body type is the drop waist wedding gown style.

Column: This body shape is usually straight up and down, with no or a slightly defined waist. The lower and upper body are more or less the same width and is a common shape amongst models. You can be a tall or a short column, but this body type is usually a slightly boyish or athletic figure. If you have the column shape, steer clear of any empire line dresses that will only make you look very straight up and down. Rather opt for elaborate ball gown wedding dresses that look stunning with this body shape.

The flowing skirt and shorter lengths are ideal for beaches, tropical locations, and informal outdoor ceremonies. The longer, fuller skirt is perfect for an evening wedding, a formal indoor ceremony, or a formal outdoor venue such as a popular public garden.

Communication and Our World

By Roger Frost

Communication begins for all of us when we are too young to speak but convey our messages by facial expressions. This method is known as pre-verbal communication.

Communication by language and writing has been the backbone of our races growth by allowing us to pass on ideas and knowledge to the next generation. This alone has created a bountiful resource that all our future generations have benefited from.

The invention of the telegraph was the first method of long distance communication which started connecting local areas together. In the 1870's the telephone was invented and together they connected small areas together and eventually the world.

Radio was the invention that allowed communications to become international and eventually connected the world. Starting out as point to point and later with the invention of the vacuum tube, became an international communication method.

On the domestic front, the Radio Act of 1912 established a radio licensing regime within the Department of Commerce and required certain ships to carry radios for communications. Due to conflict between amateur radio operators and the U.S. Navy and corporations, the Radio Act further regulated private radio communications, thus setting the precedent for federal regulation of wireless communications. This act was just the first step in the many regulations that would be enacted to control the private use of communications.

The first government intervention into communications happened in 1912 when the Radio Act was established. This act was conceived to control private amateur radio operators from interfering with U.S. Navy or commercial operators. This act was just the first step in the many regulations that would be enacted to control the private use of communications.

The first experimental communications satellite was launched in 1962. It was the first satellite to receive, amplify, and simultaneously re-transmit signals from earth. The development of satellite communications available not only to governments but also the commercial sector and individuals led to even greater volumes of communications worldwide.


Since the mid-1990s the Internet has had a tremendous impact on culture and commerce, including the rise of near instant communication by electronic mail, instant messaging, Voice over Internet Protocol (VoIP) "phone calls", two-way interactive video calls, and the World Wide Web with its discussion forums, blogs, social networking, and online shopping sites. Increasing amounts of data are transmitted at higher and higher speeds over fiber optic networks operating at 1-Gbit/s, 10-Gbit/s, or more. The Internet continues to grow, driven by ever greater amounts of online information and knowledge, commerce, entertainment and social networking.[
