Transmission Control Protocol (TCP) turns the 'best effort' nature of IP networks into reliable communication services. Tests are, however, needed to ensure optimal performance.
Rising demand for mobile broadband services and the evolution of cellular networks toward higher capacities and new air interfaces create a need to evolve existing synchronisation network architectures. Driven by the rollout of TD-LTE, public access small cells and LTE-Advanced functionalities such as enhanced inter-cell interference coordination (eICIC) and coordinated multipoint (CoMP) transmission, radio base station clocks are now required to operate in phase with sub-microsecond accuracy in addition to legacy frequency synchronisation.
Over the last few years, telecom operators have started to introduce packet based networks and thus two letters became the most pronounced ones: ‘I’ and ‘P’. This being said, the migration to a packed based technology invariable comes with a lot of interrogations and changes. Our company Oscilloquartz had to adapt our offering and services to propose new tailored solutions for our customers.
