[srsran-users] Carrier Aggregation with 2x BladeRFs

[Xavier Arteaga]

Hi Ahmad,
The problem is not the USB3 throughput, indeed there are dedicated USB3 to
PCIe controllers (https://www.startech.com/en-eu/cards-adapters/pexusb3s44v
).

The srsue could be possible but untested using two different instances of
the RF module, as long as the boards share the same clock source.

The srsenb requires that both cards are perfectly synchronized (PPS and
clock source). This implies changes in the RF module source code to run
more than one bladeRF simultaneously.

Kind regards,
Xavier
