Start-up and Rohde & Schwarz collaborate to verify LTE protocol stack


LONDON — Qasara, a fabless semiconductor start-up recently formed by a team of senior engineers, product marketing and sales from TTP Com/Motorola in Cambridge, England, is collaborating Rohde & Schwarz (Munich, Germany) on LTE protocol verification.

A joint program has been established to verify inter-operability between Rohde & Schwarz’s 3GPP LTE Virtual Tester and Qasara’s LTE compliant UE protocol stack. This collaboration should provide an independent verification of a complete, end to end, LTE protocol stack.

Focusing initially on the complex interactions and data flows in the LTE medium access control (MAC) and radio link control (RLC) Layers the ongoing programme will propose and implement joint solutions for any inter-operability and standardization issues identified.

Both Rohde & Schwarz and Qasara plan to make the results of this ongoing verification program available through the 3GPP standardisation process and to incorporate the results into each company’s future LTE products releases to customers.

“This collaboration is built on long standing relationships between engineers from Rohde & Schwarz and Qasara” added Rob Meades, chief Operations officer at Qasara.

“We are delighted to be working with Rohde & Schwarz to verify inter-operability between Qasara’s LTE UE optimized protocol stack and R&S’s LTE Virtual Tester. Rohde & Schwarz is the acknowledged leader in the field of wireless standards testing and verification. Qasara’s team has many years experience in the development of highly optimized cellular protocol stacks used in millions of cellular products deployed in the field today. The synergies were obvious from the outset.” said Michael Barkway chief executive officer of Qasara Ltd.

“This joint program will enhance both company’s LTE products and also support the 3GPP LTE standardisation and trial process,” said Anton Messmer, director of subdivision mobile radio testers of Rohde & Schwarz.
