The release consists of the following components:

SUPPORTED OPTIONS

2.2.1 NEW FEATURES (Reason for Change)

• Release introduces support for VITA 49.2 I/Q Capture and I/Q Streaming, without the need for additional API development.
• Separate UDP ports are now used for command and control:
  • The IQserver on Gflex uses port 13000 for incoming command packets.
  • Upon receiving a command acknowledgment, the server sends acknowledgement packets to port 12999 and sends data/context packets to port 13000.
  • On the PC side, two ports are opened: port 12999 for receiving command acknowledgments & port 13000 for receiving data/context packets.
• Extended Inquiry Update
  • New inquiry field added: "gpsClockServiceVersion" which represents the version of the IQserver.
• VITA 49.2 operates in Exclusive Mode, meaning it cannot be used concurrently with other measurements over USB or Bluetooth connections.
• Supports I/Q streaming bandwidths up to 100 MHz with 10 GigE Port Streaming Option. Required options:
  • 0x00BB 0000: 10 GigE port streaming

  • 0x000C 0000: Ethernet interface
  • 0x8880 0000: Superband 10-8000 MHz
• Note: For further details, please contact product management.

• Scanner provides compensation for frequency doppler shifts up to 7.5 KHz.
• Measurement is available in eTopN mode only.
• Measurement is enabled by setting “SignalMode” to “Compensated NTN LTE”.
• For eTopN mode, RX can be set to 1 or 2; for RX=2, connect two antennas (left-hand circular polarization antenna to RF1 and vertical polarization antenna to RF2).
• When the “number of RX = 2,” the scanner collects data from both RF ports and reports the maximum RSRP from each port.
• Scanner also reports the frequency offset for each Cell ID.
• MIMO parameters are not reported for RX=2 mode.

•  #8505: Gflex – Failed to pair with Android using Bluetooth connection.

2.3 Release 6.0.0.0

SCANNER COMPONENT VERSIONS

The release consists of the following components:

SUPPORTED OPTIONS

2.3.1 NEW FEATURES (Reason for Change)

• Release includes support for the two new modes that enable faster scan speeds in eTopN and Blind Scan for LTE.
• Ultra-High Speed (UHS)
• DSS Ultra-High Speed (UHS)
  • Existing Signal Modes, including Standard, High Speed Train, and DSS, remain supported.
  • Both new modes are compatible with the Layer 3 measurements.
  • UHS and UHS DSS apply only to wideband RF path measurement data modes and do not support subband, RF path + subband, and MIMO 2x2 measurements; any unsupported measurements will be rejected by the scanner.
  • UHS mode offers better performance compared to DSS UHS mode, and it is recommended that users utilize UHS DSS only when DSS is active on the network. If users are unsure whether the network is DSS, they can select DSS UHS; however, the scan speed will be slower than UHS but still faster than regular DSS mode.
  • UHS may occasionally lose some weak channels during Blind Scan, and it is recommended only when increased scan speed is necessary.
  • LTE one-time MIB/SIB1 functionality will detect MIB only once and report PBCH parameters. After the initial decode of MIB, KPI parameters for PBCH will be filled with '0.' The scanner will indicate these parameters as 'not present,' leaving them blank in the API.
  • To obtain PBCH measurements, users must run the LTE scan in continuous mode.
• Release includes support for the new layer 3 mode for LTE and NR Blind Scan.
  • New Reporting Mode 3 has been introduced, allowing one-time MIB and any SIB per PCI. This mode enables faster scan speeds in all layer 3 modes and allows users to select any SIB along with the MIB for one-time detection.
    • LTE Blind Scan supports Reporting Modes 0 (continuous), 1 (one-time MIB, SIB1), and 2 (one-time MIB, SIB1, SIB2) in release 5.1, with support for Mode 3 (one-time MIB & any SIB) added in release 6.0.
    • NR Blind Scan supports Reporting Modes 0 (continuous) and 1 (one-time MIB, SIB1) in release 5.1, also adding support for Mode 3 (one-time MIB & any SIB) in release 6.0.
    • Reporting Mode 3 is designed to be a superset of Reporting Modes 1 and 2, and it is intended to be the main mode of operation, with other modes gradually becoming obsolete in the future.
• Note: LTE one-time MIB/SIB1 functionality detects MIB once, reporting PBCH parameters as 'not present' (blank in the API) with KPI values set to '0,' and requires users to run the LTE scan in continuous mode for PBCH measurements.

• Release includes support for the below new layer 3 modes for NB-IoT.
  • New Reporting Mode 3 has been introduced, allowing one-time MIB/SIB1 decoding. The scanner currently supports SIB1, but this flag will be extended to other SIBs in the future.
  • NB-IoT Blind Scan supports Reporting Mode 0 in release 5.1, with added support for Reporting Mode 3 in release 6.0.
  • Combo mode for LTE and NB-IoT combined blind scan behavior is as follows:
    • In release 5.1, it supports Reporting Modes 0 (continuous), 1 (one-time MIB, SIB1), and 2 (one-time MIB, SIB1, SIB2).
    • In release 6.0, it will support Reporting Modes 0 (continuous), 1 (one-time MIB, SIB1), 2 (one-time MIB, SIB1, SIB2) and 3 (one-time MIB & any SIB)
    • In both releases, when Reporting Modes 1 or 2 are used, NB-IoT will remain in continuous Mode.

Note: This combo mode of operation will gradually become obsolete, and it is recommended that users avoid using the combo mode and run measurements separately instead.

• Release includes improvements for NR Blind Scan Speed.
• Added support for reporting the center frequency of the LTE network, in addition to the channel number.
• Release supports reporting of the following 5G parameters for TopN and Blind Scan:
  • Network Operation Mode: 5G Standalone or 5G Non-Standalone.
  • Fcarrier (carrier frequency) in MHz. This value is reported for 5G Standalone networks only; it will not be reported for 5G Non-Standalone networks.
  • Carrier BW: Reported in MHz only for 5G Standalone networks.
  • Carrier frequency and Carrier BW will be reported when SIB1 is enabled and detected.
• Gflex release includes a beta release for C-V2X (LTE) measurement:

• Introduces C-V2X (LTE) measurement for decoding PSCCH (Physical Sidelink Control Channel) and PSSCH (Physical Sidelink Shared Channe) channels.
• This release only supports PSCCH and includes measurements for KPI parameters such as RSSI, PSCCH RSRP, and PSCCH CINR on the PSCCH side-link channel, as well as the ability to decode the PSCCH payload.
• Supports an auto-detect capability to locate and decode the PSCCH signal without needing Resource Pool information.
• This is just a beta release and is only recommended for demonstration or lab testing purposes. Please contact Product Management for more information.
• Option for recording data to the SD card will be REMOVED from the scanner, upon upgrade to this release.
• Added support for the following bands:
  • LTE TDD 1.8 GHz Proprietary (1785-1805 MHz)

KNOWN PROBLEMS AND LIMITATIONS IN THIS RELEASE
