Sarokal Test Systems to Pioneer in eCPRI Protocol Support for 5G Fronthaul Testing

OULU, Finland, September 13, 2017 /PRNewswire/ --

The latest Common Public Radio Interface (CPRI) specification was released in August 31st, 2017.

Today, Sarokal Test Systems became the first test equipment manufacturer to offer eCPRI protocol support for Fronthaul base station manufacturers and equipment vendors.    

Sarokal´s patented technology allows the company to develop new protocols quicker and support vendor specific protocol variants. This is highly valued by our customers as they work with cutting edge technology while developing future 5G mobile networks.  

The new specification, known as eCPRI, or CPRI over Ethernet, introduces improved efficiency to match the speed and bandwidth requirements of 5G Fronthaul networks.

According to the Industry Initiative for a ommon Public Radio Interface, the main advantages of the eCPRI protocol include the following:

  • New functional split inside the PHY layer enables major reduction of the required bandwidth
  • Flexible bandwidth scaling according to user plane traffic
  • Use of mainstream transport technologies (e.g., Ethernet) opens the possibility to carry eCPRI and other traffic simultaneously in the same switched network

About Sarokal Test Systems 

Sarokal Test Systems provides innovative test solutions for Fronthaul networks. Our CPRI, eCPRI, OBSAI, JESD204 and upcoming IEEE 1914 solutions enable users like chipset vendors, Fronthaul equipment manufacturers, and telecom operators to develop, test and verify their 4G and 5G network devices. 

Sarokal X-STEP™ products provide means to generate, capture, and analyze bit accurate Fronthaul traffic with various line rates and protocols. With the 100% visibility and control over Fronthaul traffic, X-STEP can ensure full interoperability between Fronthaul devices already in the early R&D development phase as well as in the field.
