What Is a 4G Network

A 4G network is the fourth generation of wireless communication. While still in development, the foundations for the replacement of the present network is currently being researched and constructed by the cellular phone industry and other technology developers. The overall goal for the network is to provide a comprehensive and secure Internet Protocol solution with much faster data speeds than previous generations.

The first wireless network, known as 1G, was founded during the 1980s. 2G was introduced in the early 1990s as a way of allowing more transmissions to occur per communication channel. The foundations of 3G were established in the late 1990s and have been implemented throughout the majority of the world as of the early 21st century. While the 3G network was the first to allow for multimedia applications, 4G promises to take this basic technology and amplify its usage.

The specifics of the 4G network are geared towards a higher quality of service. Better reception and less dropped data and information exchanges are a priority. The International Telecommunications Union (ITU), the organization that oversees the standards of the present wireless networks, has stated that it requires substantial improvements to multimedia messaging services, including video services, in order to approve a new generation. It wants a data speed transfer rate of at least 100 megabits per second while a user is physically moving at high speeds and a one gigabit per second data rate in a fixed position. The ITU also requires interactive roaming between networks.

A variety of working groups have been established to help develop the 4G network. Proposals from these organizations include implementation of WiMax, a faster version of wireless data transfer than WiFi networks. The groups also plan to utilize packet-based information exchange based on standard IP technology. This promises to be the fastest mobile communication method without cables ever devised.

In order to make the 4G system work, the concept of smart antennas must be developed and implemented. With the establishment of the 2G and 3G networks, a number of different methods of data transmission were created. Many of these technologies can be rolled into the 4G network, however, the working groups and ITU prefer a standardized antenna system that can communicate across company lines. 

One of the proposed technologies to make this happen is known as spacial multiplexing. Spacial multiplexing uses a series of antennas linked into a single transmitter and receiver. These antennas are capable of functioning simultaneously, speeding up the space-time data exchange rates.

Overall implementation of the 3G network around the world took nearly a decade. The ITU plans to have the 4G network rolled out to the global market in a much more effective and timely manner. With the speeds and video technology, the possibilities for wireless communication will revolutionize the global communications network. However, concerns over stability and security are also prime factors in the development.

What Is BD Wise

BD Wise is a new technology from Samsung™ that seeks to add a new level of resolution to the home entertainment market, especially in the DVD market. The technology uses interactivity of other electronic products, most notably a Blu-ray™ disc player. The BD portion of the BD Wise name actually refers to the abbreviated term for Blu-Ray™ disc. Though the technology is seen as more of an enhancement to DVDs, it may also help provide some enhancement to the Blu-ray™ format as well. 

In order for BD Wise to work, both the BD Wise DVD player and the television set must be Samsung™ products. If one or the other is not, the inter-connectivity will not work, and the feature will be useless. Therefore, if you are in the market for a new player and considering Samsung™ for the BD Wise feature, then you need to make sure that your television set is compatible. In addition, the television set must be a high definition set that is capable of adjusting its own resolution. 

The main benefit of the technology is that it seeks to find the best resolution setting possible for viewing DVD products. Most DVDs were created before high-definition televisions became extremely popular. Therefore, the resolution of the DVD, while better than the old-style VHS tapes, is not set to a level where it can take advantage of the resolution available on a high definition television. The BD Wise system helps by not only providing an enhancement, but also setting the television in way that can take advantage of that enhancement most effectively. 

In some cases, user may wish to rely on their own settings rather than the automatic settings that the automatic process may use. The automatic settings may be better most of the time, but there could be times when the system does not adequately set an optimum resolution for a particular disc. In those cases, users can turn off the BD Wise feature and proceed to come up with their own settings. While this may take a little more time to set up and get right, it may be the better option for some discs. 

The BD Wise feature does not come standard on all Samsung™ Blu-ray™ players. Most of the newer, higher-end models do include the technology, but you should check the features on the box or product to make sure. The higher-end models also include other features such as BD Live, which allows users to connect to the Internet and download content.

What is a Ten Key

Ten key can refer to either the number pad on a keyboard to the right of the letters, or to adding machines or calculators. Acquiring skills in ten key is sometimes necessary to gain entry into certain fields where either a large amount of data entry, number listing, or accounting is acquired.

Learning ten key is a little bit different than learning to type. For example, the home row contains the numbers 4,5,and 6, and is typed by the index finger, middle finger and ring finger respectively. The right hand is used, though there are left handed people who modify ten key for the left hand. There are also some keyboards with the ten key pad on the left side of the keyboard.

Instead of measuring speed of ten key proficiency with words per minute (wpm) measurements as in typing, ten key is measured in either keys per minute (kpm) or strokes per minute. Most use the kpm designation when seeking employees and set a minimum kpm for applicants. Minimal proficiency in ten key is considered at least 140 kpm, though some companies which require only a little data entry might accept less.

Employment agencies frequently ask for applicants to take typing and ten key tests so they can pass this information along to interested employers. Usually most people gain proficiency in a short period of time, since there are fewer keys to learn. If you claim a certain kpm rate, however, you must be certain you can prove consistent error free ten key typing at this rate.

Few traditional ten key classes exist for those who wish to become proficient. However, there are some excellent software based courses that can easily help one acquire the skills to perform proficient ten key work. Many consider one the best of these to be Mavis Beacon Teaches Typing, which teaches not only traditional keyboard typing but also ten key fingering. The software is available on both PC and MAC platforms and tends to be fairly inexpensive, usually about 20 US dollars (USD). 

With a few weeks of practice, you can usually learn all the keys of ten key and demonstrate proficiency. If you are already an accomplished typist, the skills may take less time to acquire.
