It is really cool. I have some questions.<p>> There are two embedded antennas to ensure that we can always correct any internal frequency drift by syncing to the cell network.<p>What do you mean? Do you have your own DSP stack to deal with that while user receiving/transmitting? If there is, do you provide any control over it?<p>Aside from that,<p>- What is the compatibility with open source LTE, 5G solutions(SRS, OAI, etc.)?<p>- I couldn't see PPS input. Are you planning to add it with daughterboards?
