13 Over–the–Air Measurements (OTA) – LTE FDD Option
370, LTE TDD Option 371, 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), 372 (LTE TDD), 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), LTE TDD
(Option 371), and Verizon 5G TF (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.
