Iridium Services


Iridium Services Overview



Iridium is the only truly global satellite network offering unmatched communications, performance and reliability advantages. It consists of a large group of 66 low earth orbiting (LEO) satellites providing voice and data coverage to satellite phones, pages and integrated transceivers globally.

SatPhone Shop allows users to access Iridium voice, data and SMS along with other specialized packet data services through our Telstra dealership.

Here is a great video that shows how easy it is to place a call using an Iridium handset. The handset shown in this video is the Iridium 9555, the call could just have easily been made for the alternative handset the Iridium Extreme 9575.

Great reasons for using an Iridium Satellite solution from Telstra



Coverage

Iridium satellites cover Australia and its surrounding waters along with the rest of the world. As long as you can get a clear line of sight to the satellite you can place a call. This means you are not dependent on GSM/3G mobile coverage and can communicate egardless of your location.

Reception

The Iridium constellation utilizes 66 satellites positioned around the globe. Their overlapping and fast moving spot beams reduces the possibility of signal blockage from nearby structures. So if a tree or building is blocking your building, as the satellite moves across the sky there is an increased chance of it being

Low altitude means a shorter transmission path, stronger signals, smaller antennas.

Audio Quality

Lower end-tend latency for satellite voice and data traffic. This means when talking there is typically less than half a second delay which is great.

National number and dialing

Subscribing to a SatPhone Shop Telstra Iridium solution means your satphone will have a mobile phone number format (0417xx) and you can dial out from the handset as if you are making a national call. This makes is easy to place calls when you need to.

Voice

Iridium provides voice coverage across the globe. Due to Iridium's low earth orbiting satellites the voice quality of an Iridium call is similar in quality and latency to a mobile phone call. Users can call other Iridium handsets, land lines and mobile phone

SMS

Iridium's Everywhere SMS service offers mobile customers a reliable lifeline to quickly and easily communicate critical information with employees and loved ones anywhere on the planet. Messaging service is two-way, allowing Iridium users to send, receive, and respond to messages that are stored for up to seven days on the network and automatically delivered when phones are powered on.

Direct Internet

Direct Internet is a service that increases the throughput of email, web and FTP applications over the Iridium network. Direct Internet Data Service provides connectivity from a PC, through your Iridium terminal, directly to the Internet through dedicated servers at the Iridium gateway. This service utilizes transparent compression, resulting in effective throughput data rates higher than the 2.4 Kbps service that Iridium's data service operates at. The actual throughput will depend on the content being transferred and the protocol used. (Graphics and images will result in lower overall throughput, text will result in higher overall throughput.)

To use Direct Internet Data Service, you need a compatible PC or laptop, a data cable, an Iridium handset/terminal and a Telstra Iridium simcard that is provisioned with data access. You must also install the Direct Internet 3.0 software on your computer.

Data

Iridium Dial-Up Data Service is an asynchronous, circuit switched, 2400bps, bi-directional service. Circuit Switched Data allows dial-Up services just as you would use the modem on your computer. In essence, your terminal appears as an external modem to your computer. You will be able to use Dial-Up Data service just as you would use the modem on your computer to dial a call through the public switched telephone network (PSTN). The only differences include the dialled telephone number must conform to the international dialing pattern used by Iridium, and you will use your Iridium phone as the data modem. In essence, your Iridium phone appears as an external modem to your computer.

To use Iridium data, you will need an Iridium handset/terminal and a Telstra Iridium simcard that is provisioned with data access. You will also need to have a compatible PC/laptop or controlling device to manage the data connection.

SBD

The Iridium Short Burst Data (SBD), a data service, enables value-added applications to send and receive short data transactions of less than 2 KB in periodic time intervals efficiently. It is ideal for remote monitoring applications used for asset tracking, remote telemetry, and pipeline monitoring.

The maximum length of Mobile-Originated SBD message is 1960 bytes, the maximum for Mobile-Terminated SBD messages is 1890 bytes. Global network latency for the delivery of messages ranges from 5 seconds for short messages to 20 seconds for longer ones.

Short Burst Data is an additional subscription service, please contact us for further information.
