FEATURES
Iridium is a low Earth-orbiting satellite system providing a new level of wireless connectivity at lower costs.
Strategically positioned in space, Iridium’s cross-linked grid of 66 low-earth orbiting satellites form a seamless communications grid where wireless signals traverse overhead instead of through ground-based calls. Anywhere in the world, especially in remote areas where there is no terrestrial coverage, Iridium cuts across boundaries and obstacles to communications. The competitively priced Iridium handsets provide users with substantial cost-savings while offering almost instantaneous communications at superior quality and clarity.
Iridium allows transmission of:
Voice:
Make and receive voice calls anywhere in the world.
Data (2.4 kbps):
Connect the Iridium phone to a PC. Access the internet or corporate LAN. Send and receive e-mails.
Voice Mail:
Allows a caller to leave a recorded message in subscribers’ personal mailbox.
Call Forwarding:
Allows subscribers to redirect incoming calls to another phone number.
SMS:
Allows subscribers to send and receive short text messages of up to 160 characters.
Prepaid Solutions:
Pre-paid services are differentiated into two types; pre-paid SIM is used where there is one SIM and one user, Crew-calling scratch cards are used where there is one SIM and multiple users.
1. Prepaid SIM
Pre-paid SIM service is allows users to purchase e-vouchers for topping-up their prepaid call units and adding expiry to their Iridium service.
Prepaid SIM users do not have monthly subscription charges. The call units are deducted only when calls are made, and this service is suitable for seasonal users without regular daily usage.
1.1 E-Vouchers
There are two E-Vouchers, one for 75 minutes (4,500 units) and the other for 500 minutes (30,000 units). They are valid for 1 month and 12 months respectively. There is no activation fee for both.
1.2
Add Minutes/Add Expiry E-Vouchers
Subscribers also have the flexibility of adding Minutes (in 50 minute increments) and extending the Expiry (1 month increments) of their e-vouchers.
2. Crew Calling Scratch Cards
Pre-paid scratch cards can only be used on Crew Calling SIM cards. These scratch cards come with denomination of 20 minutes.
Short Burst Data (SBD)
Iridium’s Short Burst Data (SBD) Service enables value added applications to send and receive short data transactions of less than 2KB in periodic time intervals efficiently using the Iridium 9522 L-band transceiver.
The maximum length of Mobile-Originated SBD messages 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.
RUDICS E-mail
The Iridium RUDICS (Router-Based Unrestricted Digital Interworking Connectivity Solution) E-mail service allows subscribers to take the Iridium solution even further.
The Iridium phone acts as an external modem when connected to the subscribers’ PC, allowing them to send e-mails anywhere in the world with their Iridium satellite phone.
APPLICATIONS
On land and at sea with 100% global coverage including the polar regions, the Iridium system’s unique ability to support voice and data communications in remote regions makes it ideal for maritime users, oil, gas & mining industries, international aid agencies, government & military, forestry and other land-mobile users.
Iridium’s SBD service is ideal for remote monitoring applications used for asset tracking, remote telemetry and pipeline monitoring. It opens up new capabilities for applications in the oil, gas, rail, maritime, utility, government and military sectors. The Iridium 9522 L-band transceiver also supports circuit data and voice applications.
Iridium RUDICS E-mail service is ideal for those who have a need for basic e-mail while on the move in remote regions. The key benefits of using Iridium RUDICS E-mail over conventional PSTN Connectivity solutions include:
-Elimination of analog modem training time.
-Increased call connection quality, reliability, and maximized throughput.
