- 1. First the receiver is tuned to the first specified SDM channel number. Legal channel numbers are received in MSG_BGAN_START_SKYSCAN.
- 2. After a settling period of 6 ms the RM initiates an estimation of the channel power. Two channel power estimates are calculated; the wide estimate is calculated in a 36 kHz bandwidth and the narrow estimate is calculated in a 14 kHz bandwidth.
- 3. After approximately 30 ms the RM will have estimated the channel power in a narrow and a wide bandwidth.
- 4. Steps 1 and 2 are repeated until the channel power of all the requested frequencies has been estimated.
- 5. When this request is carried out the power estimates are returned with the response: MSG_BGAN_CHECK_POWER_RESP.

- 1. First the receiver is tuned to the specified L-band frequency.
- 2. After a settling period of 6 ms the BGAN XL Radio Module initiates an initial acquisition (due to the unknown frequency offset of the global channel).
- 3. The BGAN XL Radio Module now begins to estimate a coarse frequency offset using the assumption that a F80T025Q1B bearer is present.
- 4. After 122 ms a fairly good estimate of the coarse frequency offset will be available and the BGAN XL Radio Module begins the acquisition of the bearer (searching for known patterns).
- 5. The outcome of this acquisition is either unsuccessful or successful:
- 6. In case of a successful acquisition, subsequently CNo reports (MSG_BGAN_WAVEFORM_CNO) will now be delivered every 80 ms until acquisition fails (e.g. due to poor signal quality) or the BGAN XL Radio Module is given new instructions.

- 3. Writing the value ‘result=255’ to the .result parameter will trigger a request which will be completed once the .result value is once again different from ‘result=255’.
- 4. When the request has been processed, the result is written back to the .result parameter. The value will always start with the text ‘result=

- 3. The RM responds by sending MSG_BGAN_SKYSCAN_ALLOWED_RESP. If valid = true then the RM responds by sending MSG_BGAN_START_SKYSCAN with one or more channel numbers of global BGAN signal carriers.
- 4. Initiate the signal validation algorithm in the RM.
- 5. Loop step 4 according to the antenna pointing procedure.

Product overview
3.2.1 Integration options
The architecture of the BGAN XL Radio Module has been designed with flexibility in
mind to enable easy integration into all different kind of terminal architectures. Apart
from the various user interfaces defining a given terminal the integrator will only have
to implement an antenna system (incl. HPA/LNA) and a SIM card interface.
To speed up the development process Cobham Satcom offers a development platform
for the BGAN XL Radio Module and different kind of integration services e.g.:
• Support of BGAN XL Radio Module integration with 3rd party antenna system.
• Support/integration of complete Inmarsat type approved BGAN XL Radio Module
solution incl. antenna system into customers application.
3.2.2 Typical application
A typical terminal based on the BGAN XL Radio Module contains a board processor
and an application processor in addition to the BGAN XL Radio Module itself.
To ensure correct operation of the terminal the board processor shall provide the
BGAN XL Radio Module with configuration parameters like e.g. terminal class and
output power and control information like e.g. SIM card information. The board
processor functions can, if desired, be integrated into the application processor.
The application processor handles user interfaces like e.g. Ethernet LAN including
DHCP and NAT, USB, Analog 2-Wire (POTS) and ISDN and the associated protocol
stacks. It also implements GUIs and PABX functions.
