In a 5G network, the CU enables consolidation of upper layer protocols and management across multiple DUs. Envisioned to be implemented in a datacenter type format, the CU enables cost-effective implementation of very-high-capacity-networks.
We offer high-reliability, high-performance and network-proven solutions in our portfolio of SyncE, IEEE 1588, oscillators and clock management products. These innovative technologies are available to address the design challenges of 5G network infrastructure with innovative technologies and meet your most stringent requirements.
In a 5G network, the DU performs the classic modem functionality of a base station. The DU is typically deployed within the RAN and may be placed very close to the 5G cell tower.
Distributed Unit (DU)
Central Unit (CU)
Radio equipment, including Radio Units (RUs) and Remote Radio Heads (RRHs), is fundamental in wireless infrastructure. With mobile traffic demand projected to grow exponentially over the next few years, networks are being designed to deliver a greater number of connections, as well as higher bandwidth per connection. To support these objectives, 5G is expected to drive radio bandwidth >10x.
RAN
We offer a complete timing solution to quickly enable frequency and phase synchronization and reliably operate it in a field deployment.
A carrier-grade design with flexible capabilities is vital to enable circuit to packet network migration for high-speed data services and wireless backhaul, and to deliver 3G, 4G/LTE, LTE-Advanced, 5G wireless, as well as broadband multimedia to the network edge and customer premises.
The TimeProvider 5000 is an IEEE 1588 Precision Time Protocol (PTP) grandmaster clock that enables communications service providers to build a stable, robust and reliable network infrastructure.
