IEEE 1588v2
To meet exploding bandwidth demand, mobile operators are upgrading
backhaul networks to packet-based technology. This transition brings a
major challenge: maintaining synchronization, a mandatory requirement
for mobile network stability and handset handoff. As Ethernet is an
asynchronous technology, newer methods and standards have been
introduced to implement synchronization over Ethernet. Namely, IEEE
1588v2 PTP is becoming the choice solution for synchronization
distribution, as it uses an exchange of timestamp between master and
slave devices, thus providing frequency, phase and time sync over the
existing Ethernet infrastructure.

So strong a connection, in fact, that these markets can no longer be looked at in isolation, though today's broadband access market still primarily is a matter of competiton between fixed line providers.
