What is the Latency for the BGAN Network?

The BGAN network typically provides a Latency of between 900 - 1100 milliseconds.

What can affect the Network and impact email performance?

Helpful tip: You can achieve a more cost-effective and efficient email service by ensuring that your email client/server settings have been optimised for satellite networks. For further assistance, please contact your distribution partner (DP). Cause and effect Latency Latency, or delay experienced over the network, impacts the performance of acknowledgements and therefore of packet sizes. The BGAN network typically provides a latency of between 900 - 1100 milliseconds. Jitter This is the range by which the latency of a network varies. The greater the variation the higher the jitter and therefore the higher the impact on the email protocols used. A Standard IP data connection tends to have a higher Jitter than a Streaming IP data connection. Overheads When a protocol sends email, there is an associated overhead, for example in the use of headers and packet acknowledgements. The percentage size of the overheads varies depending on the protocol . Dynamic Packet size Dynamic packet size determines the volume of data that can be sent per packet in comparison to the error correction information. Dynamic packet size varies depending on the protocol, but plays a significant role in FTP. It enables throughput to therefore vary depending upon the quality of the service.

Are short dialling codes supported by BGAN?

Distribution partners (DPs) are required to provide Inmarsat with the short dialling codes they plan to use along with their full National number.

What is the short code to collect voicemail messages?

Dial 57# to collect voicemail.

Can an SMS be sent to more than one recipient at a time?

Yes. The BGAN Launchpad system can send an SMS to an unlimited number of selected recipients.

Is each SMS sent charged separately?

Yes. There is a charge for each individual message.

How do I know if BGAN can be used in a particular country?

Inmarsat has a dedicated regulatory team that confirms the licensing situation in all countries. A licensing spreadsheet is available on the Inmarsat Connect website.

Is there a map which shows the edge of BGAN coverage?

The coverage maps are not definite because the edge of coverage is not static. Geo satellites reside within a "box" in space, inside which they drift from one edge to the other (typically 0.5 degree drift). As they drift, so the edge of coverage moves. However, the I-4 Eye will provide an indication of BGAN coverage.

Is a PDA version of BGAN Launchpad available?

Currently it is possible to use a PDA with the terminal by connecting over the Bluetooth interface. An initial configuration using BGAN Launchpad is necessary . This involves setting the terminal to automatically open up a standard data session when turned on. A PDA version of BGAN Launchpad is currently being developed.

Is 'BGAN Launchpad' able to send a SMS directly after registration?

Once registered, the BGAN Launchpad software will be active and able to send and receive SMS.

What is the process to set up voicemail?

Dial 57 or +870 772 001 899 from the BGAN network. Then follow the instructions on the recorded voicemail message. The user will be asked to select a PIN number (typically four characters or more) and to state their name. They will then be directed to create a personal greeting for their voicemail. When a new message is received, the network will automatically send a text (SMS) to their terminal. The user can then dial short code 57 to listen to the message.

When I receive an SMS, do I pay for this?

No, the sender pays for the SMS

Can a SMS be sent to a pager service?

Some paging systems have been modified to receive text messages from the local mobile networks. The user will be unable to access the service if they are outside their own country because the numbering scheme (or plan) for pagers is not part of E.164 numbering.

What is the total power output of the I4 satellite?

The total EIRP (Effective Isotropically Radiated Power) that can be allocated to the narrow spot beams is 67 dbW.

Is there global barring available on BGAN?

SIM cards can be barred or disconnected for any location by the distribution partner (DP).

How does Voice Over Internet Protocol work, is it point-to-point?

We have an IP bearer that is transparent to applications, VoIP is just one of those. We have tested common VoIP providers such as Skype.

What is the maximum number of bearers in any one spot beam?

This is dependent on demand for the BGAN service. Inmarsat has the flexibility to dynamically assign spectrum and power where it is needed. Capacity can be adjusted and allocated depending upon demonstrated demand for the BGAN family of services.

What is the purpose of the new 176k streaming rate?

The new streaming rate is aimed at providing flexibility to the current streaming rate options. It is available to users who are price conscious and require high rates of streaming above 128kbps. The 176kbps streaming rate is particularly appropriate for users looking to stream 'talking head' shots or shots with low levels of background movement. The new stream rate will also offer a higher rate of streaming than what is currently available in the rare occasions when congestion occurs by supporting multiple 176kbps streaming connections in one BGAN channel.

Who is the 176k Streaming aimed at?

176kbps streaming will be available to all Hughes 9201 and Thrane E700 terminal users. The Inmarsat streaming services provide a guaranteed pipe for IP based applications, in particular customers with UDP applications such as video/audio streaming use the service eg. Broadcast media and government users.

What are the benefits of the new 176k streaming rate?

The benefits of the new 176k streaming rate relates to the fact a lower streaming rate allows for flexibility for various applications which may not always require the higher 256k or X-stream rates.

Is the 176k Streaming Service a guaranteed streaming rate?

This is a guaranteed 176kbps in the forward and return directions in-line with streaming rates currently available.

Can the new 176k streaming rate be used on existing BGAN terminals?

The 176k streaming rate is accessible with Class 1 terminals only; Thrane & Thrane EXPLORER¿ 700 or Hughes 9201. There is no need to purchase any additional equipment to access the BGAN 176k streaming rate.

Is the new streaming rate automatically added to sim cards?

You will need to contact your Distribution Partner to confirm you are provisioned for the new 176k service to ensure you are billed accurately. As this does not constitute a change of package, there should be no change to your existing contract.

When can the new streaming rate be applied and when does it become available?

176k Streaming is due to be launch on June 2nd 2010.

Do we need to upgrade the LaunchPad to take into account the new streaming rate?

A new LaunchPad version including 176 Streaming support will be available from the 2nd June for Windows and MAC OSX on the Inmarsat support site -

Can the new 176k streaming rate be accessed via the Terminal web interface?

Both Thrane & Thrane and Hughes are working on upgrading their firmware to support 176, Inmarsat will notify the channel once the firmware is available. In the meantime Thrane and Thrane users are able to use the option of creating a new streaming profile, for instructions on how to do this please refer to the thrane manual/user guide.

Is the 176k streaming rate replacing an existing rate?

The new 176k streaming rate is offered as an additional service option, all other streaming services will remain.

Is 176k streaming rate compatible with applications that are set for other rates

As with current BGAN streaming rates, the 176k streaming rate is compatible with leading broadcast video applications. Inmarsat has conducted rigorous testing to ensure that these applications are compatible with the newer streaming rate. Most applications will allow higher or lower rates to be applied however if you are unsure please consult the application user guide for confirmation.

What applications work efficiently with the new 176k Streaming Rate?

Please refer to the Support Tab on the Inmarsat Website where user guides are provided on tested solutions.

How is the 176k streaming rates charged?

Even though this is a new streaming rate, charges are still made on length of time the connection is open as opposed to the amount used. This is in-line with existing streaming rates.

Are there any further expected new streaming rates to be made available?

Currently there are no plans to add any additional streaming rates.

Can I request 176k Streaming if I have 256k Streaming?

If a SIM card is provisioned with Streaming 256K you will be able to request for 176K.

T&T Explorer 700 shows up as 256k on the LCD and not 176k when requesting 176k

The manufacturer (Thrane) confirm this is correct and a fix will be implemented in the next firmware release which will enable the terminal to be made aware of the new 176k service.

Are Inmarsat Satellites affected by Solar Magnetic Disturbances?+ More Questions

1. Does Inmarsat have any information about SMD (Solar Magnetic Disturbances) as it pertain to the Inmarsat satellites? We monitor the published space weather environment e.g. as provided by NOAA. At geostationary orbits (~36,000 km above the Earth) a satellite is normally offered some protection from Solar particles by the Earth's magnetic field. But at times of high Solar activity (e.g. during flares or coronal mass ejections) the extent of the Earth's magnetic field can be reduced, resulting in the satellites being exposed to higher than normal flux of charged particles. 2. Are the satellites protected in any way from this type of disturbance? Yes, satellites are designed to handle increases in the charged particle environment due to Solar activity. The satellite and important sub-systems are designed around the concept of a Faraday cage. This allows charge to build up evenly on the outside body whilst protecting the components inside. Shielding is also used to reduce the risk of the passage of an energetic particle interacting with critical components. During the manufacturing process ground tests are performed in which key components are exposed to the particle flux expected to be found in the space environment. Additional protection can be used including majority voting schemes and hardwired back-ups. No amount of shielding can provide total protection, so events do occur. These are sometimes referred to as single event upsets (SEUs). Typically, satellites have redundant on-board systems allowing a back-up to be used whilst an SEU is investigated and the affected equipment returned back to full operations. 3. Will we see a total failure, an interruption of service or something else? No failure or interruption to services are expected.

Will the Sun cause any connectivity issues?

"Sun Outages (interference) caused by the passage of the Sun behind the satellite should not impact BGAN services. The period of interference occurs twice a year and the duration of each event is limited to a few minutes. For the Inmarsat SAS antennas these Sun Outages are known beforehand and handled as part of nominal operations. The beamwidth of the L-band user terminals is such that that they are not impacted by the Sun within the field of view."
