#IRIDIUM 9555 SOFTWARE#The menu system, display, and software of the 9555 have also been updated. The handset closely resembles a larger cell phone, but works very differently with regard to its communications path and network infrastructure. I recorded one of the calls that I made to an associate so you can judge this for yourself. After placing a few calls on the new handset, I can say that the audio quality seems to be much improved from my older 9505 unit. There are several noticeable improvements in the latest phone in terms of design, operation, software, and functionality. This system currently offers voice and data communications virtually anywhere, even in the most remote regions of the world, as I can personally attest. I have had extensive experience with the Iridium network since it commenced operations, and have used each of the three different handsets (the 9500, 9505, and 9505A) that were available prior to the 9555. The system works while flying, driving, walking, or onboard a ship. While traditional geostationary satellite services, such as Inmarsat, requires the radio to be in one position during use so that the antenna can lock into a satellite beam, Iridium is entirely different. The network was designed to provide secure communications on a global basis from a handheld that weighed about 12 ounces and could fit in your back pocket. The Iridium network, conceived, engineered, and built by Motorola, launched in 1997 as the first commercial constellation of 66 low earth orbit (LEO) satellites, crisscrossing the planet at about 500 miles above the Earth. The new handsets, with accessories, sell for about $1,700, and according to Iridium, are available now. It has been a primary vendor for Iridium from the first implementation of the network. I received one of the first 9555's that was delivered to World Communications in Chandler, Ariz., by Iridium. It has been several years since any significant changes have been made in its handheld equipment, so for current users, this should be welcome news. Iridium has begun delivering its latest generation handset, which signals a new era for the global satellite carrier. The new Iridium 9555 satellite handheld looks and acts like a cellular, but operates virtually anywhere in the world.
