12 Over–the–Air Measurements (OTA) – LTE FDD Option
370 and 5GTF Option 377 (CPU2 Only)
OTA mode measures signals at the SA RF Input Port 2 connector.
OTA mode requires the FieldFox to have SA mode (Option 233 on combination
analyzers), GPS (Option 307), and CPU2 installed.
Recommended, but not required, preamplifier (Option 235) to improve receiver
sensitivity.
With
Options 370 (LTE FDD) and 377 (5GTF), network designers can ensure
that networks have enough resources to carry out handovers (re-selection)
when users move between cell towers on the same 5G network as well as in
between 5G and 4G networks (intra/inter-radio access technology). The
FieldFox OTA measurements support LTE FDD (Option 370) and Verizon 5GTF
(Option 377) over-the-air demodulation of single acquisition, multiple cell
towers, or multiple acquisitions for multiple component carriers (CCs). The
FieldFox display can be configured to show data formats such as table, bar
chart, spectrum and strip chart of key performance indicators (KPI's).
By integrating over-the-air (OTA) measurements with cable and antenna test
(CAT), full 2-port vector network analysis, spectrum analysis, and real-time
spectrum analysis (RTSA), the FieldFox can be used for base station setup and
verification.
