Free Ringtones For Your T-mobile Phone - By: Low Jeremy In the industrialized world, mobile phone is a necessity. With the way telecommunication changes from time to time, more and more cell phone technologies are designed to meet customer demands. In bringing new features and innovative ideas, truly, mobile devices are such an attraction to ... Featured ArticleNokia Demonstrates First Xhtml Microbrowser On Standard Mobile Phone The new microbrowser brings WAP and WEB worlds together, available for licensing and on Nokias terminals this year Nokia, the world leader in mobile communications, today demonstrated the first XHTML microbrowser on a standard mobile phone. XHTML is the language that will be used to create all content regardless of whether it is for the fixed Internet or the mobile phone world. By narrowing the gap between wired and wireless content, this technology greatly accele ...

Driving For Better Broadband - By: Michael Russell The Alcatel Broadband For All survey had interviewed 2,850 people in cybercafés and early broadband users by phone across Brazil, Russia, Egypt, Kenya, India, China and in major towns in Malaysia. A total of 300 people in cybercafés were surveyed face-to-face plus 100 online surveys of new broadband... 3. Impedance Is Similar To Refractive Index In Optics - By: Driskill The resonant frequency is related to the electrical length of the antenna. Antennas have practical use for the transmission and reception of radio frequency signals, which can travel over great distances at the speed of light, and pass through nonconducting walls. Typically an aerial is tuned for a ... 4. Loss Resistance Usually Results In Heat Generation Rather Than Radiation, And Therefore, Reduces Efficency - By: Driskill Complex impedance of an aerial is related to the electrical length of the antenna at the wavelength in use. One limitation of this aerial is that it does not radiate or receive in the direction in which the rod points. The vast majority of are simple vertical rods a quarter of a wavelength long.b... 5. With The Development Of Wireless Routers That Come With A Wifi Aerial, Work Using The Computer Can Be Done Without The Need To Connect Any Wires - By: Driskill With the development of wireless routers that come with a WiFi aerial, work using the computer can be done without the need to connect any wires. For a transmitting aerial, this is the antenna itself. Microstrip are the most commonly used in mobile communications, satellite links, W-L... 6. Cell Phone Dictionary - By: Michael Russell With all of the new technology in the cell phone industry, it can be difficult at best to keep up with what everything means. You need to understand the terms before going out and purchasing your next cell phone. Here is a quick list of terms to help everyone gain a better understanding of cell phon... 7. Eagency Announces New Ceo - By: Prweb Wireless Enterprise Symposium 2004 - Chicago, IL - May 17, 2004 - eAgency Systems, provider of sales force automation and customer relationship management solutions for the Small Office/Home Office market, announced its new CEO, Charles R. Cronin, Jr. (PRWEB) May 2... 8. The Receiving Aperture Can Be Greatly Increased By Bringing The Loop Into Resonance With A Tuning Capacitor - By: Driskill The small loop aerial which is made so that both ends of the wire connect to the radio less than a wavelength in circumference. However, when the current stops, these fields collapse, returning energy to the power supply. A dielectric resonator is a variation on the conventional antenna i... 9. The Dip Antenna Is Simply Two Wires Pointed In Opposite Directions Arranged Either Horizontally Or Vertically, With One End Of Each Wire Connected To The Radio And The Other End Hanging Free In Space - By: Driskill It is claimed that the dielectric contains the near field and therefore prevents it from interfering with other nearby or circuits, making it suitable for miniature equipment such as mobile phones. The quad is related to the loop in exactly the same way the yagi is related to the dip. br /... 10. Airlanes Need For Radar, Gps, Radio, Beacons, And Voice Radio - By: Driskill However, when the current stops, these fields collapse, returning energy to the power supply. It is considered to be a point in space with no dimensions and no mass. The quad antenna is an array of square loops that vary in size. The receiving aperture can be greatly increased by bringing... 11. Another Way Of Letting People Have Internet Access At Home Or In The Office Is By Adding Another Access Point - By: Driskill Unfortunately, every HDTV antenna is not alike and the quality of your picture can vary greatly depending on which antenna you choose. Another way of letting people have internet access at home or in the office is by adding another access point. This is because the signal could reach people who live... 12. Generally, Aerial Gain Is Increased Without Changing Antenna Size By Narrowing The Aperture To Increase Power Density In A Single Direction While Reducing It In All Other Directions - By: Driskill If an external HDTV aerial is not an option, perhaps because you live in an apartment or in a building of historic interest, then you'll have to go for an internal, set-top aerial. Hence the bridge will be able to detect if a aerial is either a resistive or inductive load. Reactance can b... 13. However Mechanisms Such As A Large Reflecting Dish In An Antenna System Can Greatly Increase The Collecting Area Of An Otherwise Very Small Antenna Element - By: Driskill Power absorbed by the ohmic resistance becomes waste heat, and that absorbed by the radiation resistance becomes radiated electromagnetic energy. In both cases a null will indicate when the bridge is balenced. A directional aerial could further narrow the aperture to 90 degrees for four t... 14. The Polarization Of An Aerial Or Orientation Of The Radio Wave Is Determined By The Electric Field Or E-plane - By: Driskill A SWR of 1.5:1 is considered to be marginally acceptable in low power applications where power loss is more critical, although an SWR as high as 6:1 may still be usable with the right equipment. One limitation of this antenna is that it does not radiate or receive in the direction in which the rod p... Please feel free to submit your quality, informative article for our readers. |
