(OP621-FD-LTE-NB-IOT)
Layer 3 decoding is available for FD-LTE,
TD-LTE, FD-LTE-NB-IOT, GSM, WCDMA
CDMA and 5G NR technologies. This option
provides decoding for:
•
GSM BCCH (Broadcast Control
Channel) messages
•
WCDMA BCH (Broadcast Control
Channel) Type 3 messages
In the GSM BCCH, types 1, 2, 3, 4, 9, and
type 13 messages are supported. For
WCDMA, and LTE, transport block from the
scanner enable support of the Master
Information Block (MIB) and System
Information Blocks (SIBs).
In the WCDMA BCH, the MIB and SIBs 1, 2,
3, 5, 7, 11 and 19 are available.
In the GSM BCCH, WCDMA, these
messages contain the Cell Identity and
Local Area Identification information
broadcast by the network infrastructure.
This information includes the:
•
MCC (Mobile Country Code),
•
MNC (Mobile Network Code),
•
LAC (Location Area Code)
•
RAC (Routing Area Code)
These messages also contain significant
information on the configuration, activity and
performance of the network. This includes
information concerning:
•
Neighbor list
•
Mobility management (handovers,
etc.)
•
Group and broadcast call control
•
GPRS mobility management,
transparent transport and session
management
•
Radio resource management
•
SMS messages
•
Location services
•
Uplink Interference parameters
(WCDMA).
The LTE BCCH Layer 3 option conveys
system information about the cell. These
transport blocks contain the cell identity,
channel bandwidth, mobility management
(handovers), neighbor lists, barred cells,
intra-frequency selection, public safety
messages, etc. It supports decoding of the
MIB and SIBs 1-16, 24, 25 and 32.
The FD-LTE NB-IOT Layer 3 option
conveys system information about the cell.
It supports the decoding of the MIB and SIB
1.
The CDMA Layer 3 option provides this
information:
•
Synch Message.
•
System Parameter Message.
•
Extended System Parameter
Message.
•
Neighbor List Message.
•
Extended Neighbor List Message.
•
CDMA Channel List Message.
•
CDMA Extended Channel List
Message
