Időszinkronizáció általános célú GPS modulokkal

open access: yes, 2014
Napjainkban a rohamosan növekvő adatforgalom a hálózat sávszélességének növekedését követeli. Míg a korábbi időkben a 10 és 100 Mbit/s-os hálózatok voltak elterjedőben, addig manapság ezt 1 és 10 Gbit/s-os hálózatokra bővítették.
