Sunday, December 17th, 2006Satellite telephones rely on technology that was initially developed for military purposes. Like the Internet, the use of this technology has witnessed a dramatic shift to commercial use but the military implications were again reinforced during the US conflicts in Afghanistan and Iraq. The Iridium system played a vital role in providing the commanders in Washington with real time data that was crucial for many victories. More than 20,000 troops were supplied with satellite phones for exclusive use by the Pentagon and as permitted by the US DoD. This makes it clear that the military is going to continue its dependence on satellite phone technology as much as civilians are crazy about new services on their cell phones. Another aspect of satellite phones is that local agencies like police, firefighters, medical emergency teams, and similar services can now be in touch with critical information on a real time basis.
Satellite Phone Technology
Monday, November 6th, 2006A satellite phone, or Sat phone as it is often called, is just like a regular cell phone except that it communicates directly with orbiting satellites to establish connections throughout the world. People often assume that a satellite phone means unrestricted global communication but it all depends on the technology of the satellite phone as well as the service provided whether the coverage of the phone will span the planet or just a specific area or continent. In technical terms, the satellite phone is known as the earth station or the terminal. There are several technologies in use for manufacturing these satellite phones. As a concept, a satellite phone is not new and they have been around for a long time. A satellite phone is not as compact or lightweight as a regular cell phone. In comparison, a satellite phone is typically as bulky and heavy as a cell phone from the two decades ago. The satellite phone also has a retractable antenna. Due to size and weight limitations as well as the antenna problem, people who are going into remote areas or expeditions to places where regular terrestrial communication is not possible prefer a satellite phone.
Choosing The Right Satellite Phone
Sunday, October 29th, 2006By Paul CrisYou should remember that not all Satellite phones in the market are programmed to follow identical work culture. Some Satellite phones function only in certain predetermined geographical areas and certain others may work anywhere on the globe.
HOW TO GO ABOUT IT?
1.First decide whether you need a country specific handset or a handset with global access.
2.Then decide which type of satellite phone you require. What are your options: (1) a handset which offers voice and slow access data, (2) a handset which ensures a high quality voice reproduction together with data which are basic in nature, and, (3) a handset that can offer a very high quality voice along with data which can be accessed in real good time.
Satellite Phones Or Cellular Phones. Which Should You Buy?
Sunday, October 29th, 2006Today, there is a huge selection of cell phones and cell phone providers to choose from. For most people the normal cell phone is adequate for their needs. However, if you travel a lot, particularly overseas or offshore, you will quickly find that the cell phone you bought doesn’t work because there aren’t any towers nearby, as in the case of traveling offshore. If you travel overseas, your cell phone won’t work there either as they have their own dedicated networks.

Things have come a long way since the ‘Sputnik’! Satellite systems now provide both voice and data communication for areas of the world where there is no land or cell phone coverage. Satelite telephones help us to keep in touch when in the air or out at sea. It also helps us to keep track and in contact with those brave adventurers who test the boundaries of endurance and skill. We can follow their routes, talk to them and receive photographs and film from wherever they are and be instantly ready to help when things don’t go according to plan.
