working with does not have an integrated/internal GPS capability, you can use the RADWIN

It is possible to use HSS over Ethernet with a 3rd ‐ party L2 switch instead of the
IDU ‐ H/HP. If you do so, make sure the L2 switch fulfills these conditions:
‐ Must support GbE
‐ Does not support EEE (Energy Efficient Ethernet), or
‐ If it supports EEE, it should be according to the IEEE 802.3az standard
