1 Inmarsat Network

BGAN-X (SAILOR 500 FleetBroadband, SAILOR 250

FleetBroadband and SAILOR 150 FleetBroadband) is a platform

delivering “always-on” Internet service, telephony /fax and ISDN.

The BGAX-X platform delivers a higher data rate than any of the

previous Inmarsat systems by the use of their I4 (Inmarsat 4)

satellites, the BGAN network and a new generation of small and

light user terminals.

1.1 Overview

UT’s (BGAN-X User Terminals, SAILOR 500 FleetBroadband,

SAILOR 250 FleetBroadband and SAILOR 150 FleetBroadband)

offer communications through a microwave link anywhere with a

line-of-sight to one of the Inmarsat-4 geostationary satellites.

The I-4 satellites (APAC(Asia-Pacic)@143ºE, Americas @

98ºW and EMEA (Europe-Middle East-Africa) @ 25ºE) relays

trafcbetweentheUT’sandtheSAS (Satellite Access Stations).

Figure 1-1: BGAN-X network overview

A SAS is a BGAN-X Earth Station, of which there are three – one

in Burum in the Netherlands and two on Hawaii.

The SAS houses the RNS (Radio Network Stations) and the CN

(Core Network) mainframes.

The RNS’, there are three of them (one in Burum, the Netherlands

andtwoonHawaii)managestheradiotrafctoandfromthesatellite

whereas the CN provides the terrestrial telecommunications

infrastructure and switching.

Chapter 1

Inmarsat Network

Figure 1-2: BGAN-X Radio Access Network

The CN consists of four modules, MGW (Media GateWay), MSC

(Mobile Switch Center), VLR (Visitor Location Register), SGSN

(Service GPRS Support Node) and GGSN (Gateway GPRS

Support Node).

The I-4 satellite communicates with UTs using spectrum in the L-

band (around 1.6 GHz).

The I-4 satellite communicates with SAS’s using spectrum in the

C-band (4-8 Ghz).

The I-4 satellite subdivides its L-band spectrum into a total of

approximately 600 channels in the forward (RNC to UT) direction

and the same number in the return (from UT to RNC) direction.

Each slot or ‘sub-band’ is 200 kHz wide.

The I-4 satellite increases the total channel capacity by means of

frequency reuse.

By subdividing the coverage into different beams, the same channel

frequencies can be reused many times. The same frequencies

cannot be used in overlapping beams to avoid interference but

where beams are spatially separated frequency reuse is used

extensively. Beams serving a wide coverage area offer lower data

rates and less frequency reuse. Beams serving a concentrated

coverage area offer high data rates and high frequency reuse.

1.2 Beam types

Each Inmarsat-4 satellite provides the following beams /coverage.

1.2.1 Global Beam

Global beams:

Figure 1-3: EMEA

Figure 1-4: APAC

Figure 1-5: AMERICAS

The Global beams are used only for tracking signal and Bulletin

Board transmissions from Inmarsat.

There are only one Global beam from each satellite.

1.2.2 Regional Beams

Regional beams:

Figure 1-6: EMEA Figure 1-7: APAC Figure 1-8: AMERICAS

The Regional beams are used for registration after power up, Call

Announcements and Call set-up when signed in.

The actual Regional beam is selected on basis of the GPS position

of the FleetBroadband.

When the FleetBroadband is in idle mode, it is “resting in the

Regional beam. Also if the FleetBroadband has a data session

up running, but is not transferring any data up or down, the

FleetBroadband is returned to Regional beam to free resources

for other users, though the network is aware of the allocated

channel, which will be given back as soon as a data transfer is

started again.

There are 19 Regional beams from each satellite, covering the

entire satellite footprint.

Chapter 1

Inmarsat Network

1.2.3 Narrow Beams

Narrow beams:

Figure 1-9: EMEA Figure 1-10: APAC Figure 1-11: AMERICAS

The Narrow beams are used for the actual communication, data,

voice and fax. The communication is taking place on a shared

channel, which can be the reason for a lower throughput that

expected.

The actual Narrow beam is selected on basis of the GPS position

of the FleetBroadband.

There are >200 Narrow beams from each satellite, covering the

entire satellite footprint.

1.2.4 Beam Hierarchy

WhenaBGAN-XisterminatingitstrafcconnectioninaNarrow

Beam, it is immediately transferred back to the Regional Beam.

When the last BGAN-X has left a Narrow Beam, the Forward

Carrier in that beam is removed and the Forward and Return

Channels are returned to the pool of free satellite capacity.

To avoid congestion in Narrow Beam by idle IP connections, the

RNS will also time-out a variable bit rate connection if no packets

are exchanged for a period of time and then hand back the

BGAN-X to the Regional Beam. If packets subsequently arrives

at the BGAN-X or the RNS for this connection, then the satellite

channels are immediately allocated in the Narrow Beam (if they

are not already there), and the BGAN-X is returned to the Narrow

Beamandtheconnectionisrestored,readytoexchangetrafc.

The BGAN-X does not need to use a keep-alive mechanism to

keep the connection open.

1.2.5 Elevation bands

The observed performance or speed of the IP data connection is

inuencedbymanyfactors.

With the three different antenna sizes, of the three classes, the

achievable data rates will differ. Essentially, the larger the antenna

the greater the achievable bit rate, particularly in the uplink or

return direction. Larger antennas will also enable higher bit rates in

more demanding ‘edge of beam’ locations and will provide service

to lower elevation angles towards the satellite and in conditions of

high fading (e.g. calm water conditions (mirror effect)). In addition

the performance of the antenna in terms of gain, G/T and ability to

reject multipath will also affect the achievable bit rate.

Elevation bands:

End users will also experience that the number of users sharing

the bearer, at any particular time, will have an impact on the

achievable bit rate, along with at low elevation angles for a

specicterminal/linkconditions.Each512kbpsbearerneedsto

theoretical bandwidth available for users will be 432 kbps. As has

The BGAN-X network maximises the use of this satellite capacity

by dynamic re-allocation to meet the demand, to ensure bandwidth

is always available when and where the users need it.

1.3 BGAN-X units

1.3.1 BGAN-X Terminal classes and capabilities

The BGAN-X system supports a range of FleetBroadband types

with differing capabilities. The BGAN service is launched with

three FleetBroadband classes, all maritime devices, i.e. tracking

units automatically pointing towards the satellite during use.

The Class 8 system (SAILOR 500 FleetBroadband) is a high

performance terminal with a large antenna (16 patches (the old

antenna has 19 patches)) supporting the maximum data rates.

The Class 9 system (SAILOR 250 FleetBroadband) is the same

terminal as SAILOR FB500 but has a somewhat smaller antenna

(three helixes) and can support marginally lower data rates.

The Class 14 system (SAILOR 150 FleetBroadband) has an even

smaller antenna (two helixes) supporting the lowest data rates.

SAILOR FleetBroadBand

Training Manual

Under ideal conditions the most powerful FleetBroadband can

transmit and receive at a data rate of 492 kb/s before subtracting

signalling overheads.

Each of the FleetBroadband will have different capabilities. Sharing

capacityefcientlyamongdifferentpopulationsofsystemclasses

with different capabilities and in different link conditions across

thesatellitecoveragerequiresconsiderableexibilityinmanaging

channel capacity. There are a number of capabilities shared by all

the current three FleetBroadband classes.

A FleetBroadband system can transmit bursts of up to 200 kHz in

bandwidth and can receive one or two carriers at a time (typically

one) also within a 200 kHz band.

The frequency tuning of a FleetBroadband transmitter and receiver

operate independently.

FleetBroadband can transmit and receive simultaneously.

FleetBroadband receive continuous forward transmissions but

transmit in 5 msec. or 20 msec. bursts in the return direction.

FleetBroadband transmit either intermittently or up to a 100% duty

cycle.

Once the FleetBroadband has acquired the global beam carrier

all subsequent FleetBroadband receive or transmit tuning is

commanded by the RNS.

FleetBroadband can support multiple trafc connections

simultaneously.

Different FleetBroadband classes have different capabilities in

terms of numbers of connections that they can support. As far

as the RNS QoS (Quality of Service)management is concerned

these connections are managed no differently to connections from

separate FleetBroadband’s.

At present the network supports no more than one circuit

switched call per unit.

Up to eleven simultaneous IP connections are supported

(FleetBroadband class permitting).

1.3.2 Subscription and Quality of Service (QoS)

When a trafc connection is initiated the BGAN Core Network

checks that the user has subscribed to the service that they have

requested. For IP services, the subscription dictates which IP

networks the user is permitted to access via BGAN (e.g. corporate

VPNs). For each of these networks the subscription sets the

maximum quality of service (bit rate, trafc class etc.) that the

user is permitted to request when initiating a packet session to

that network. The QoS (Quality of Service) parameters supported

inBGANfollowtheUMTSRelease4asspeciedbytheUMTS

standardisation body, 3GPP.

The subscription sets the maximum QoS for an IP connection but a

user may choose to connect using a lower value. E.g. a subscriber

can use a variable bit rate connection even if the subscription to

the IP network permits a guaranteed bit rate but not vice versa.

8

1

Chapter 1

Inmarsat Network

Alternatively there could be choose a 64 kb/s guaranteed bit

rate bearer even when the subscription permits 256 kb/s, but not

vice versa. The FleetBroadband supports a number of advanced

packetlteringtechniqueswhichallowprecisecontrolofIPQuality

of Service. Depending on the capabilities of the system class it is

possible to connect multiple computers to a single FleetBroadband

and run separate connections to different networks with different

QoS handling. IP packets to and from a FleetBroadband can be

de-multiplexed onto multiple simultaneous BGAN connections

each with separate QoS handling. This allows, e.g. video packets

to be carried on a guaranteed bit rate bearer at the same time as

TCP packets are carried on a variable bit rate bearer where both

typesoftrafcaresent toand froma computerconnected toa

FleetBroadband with a single IP address.
