Did Can replace twisted pair cable (FTP) with Canopy Lite?

In cases for which the product was headed - 2 km, 512 throughput - I can get the same stability we have with cable?

Stability: low variation in speed tests.

Ex: low latency (<10ms), low variation in speed (on dedicated link 256 kbps, speed does not have peaks higher than 260 and not fall below 250), etc.
