On the current O-RAN ALLIANCE International PlugFest Fall 2023, hosted on the i14y Lab in Berlin – supported by Deutsche Telekom and EANTC and i14y consortium companions, Rohde & Schwarz and VIAVI Options have introduced their built-in answer for conformance testing of O-RAN Radio Items (O-RUs). With their joint check answer, which mixes each firms’ industry-main capabilities, they verified Analog Units’ progressive 8T8R O–RU reference design in response to each O-RAN and 3GPP pre-conformance specs.
Community disaggregation requires interoperability between Open RAN community tools supplied by totally different distributors. O-RAN radio items (O-RUs) want to evolve with each 3GPP requirements and O-RAN specs. Fronthaul conformance assessments as outlined by the O-RAN ALLIANCE confirm the correct conduct of fronthaul interfaces and make sure that the O–RU designs are interoperable with the O-RAN distributed unit (O-DU).
Rohde & Schwarz and VIAVI Options are each main in wi-fi communication testing and energetic in specs growth within the O-RAN ALLIANCE and 3GPP. Collectively they’ve developed an O-RAN conformance check answer supporting a number of Open Testing and Integration Facilities (OTIC).
O-RAN ALLIANCE International PlugFests are periodic occasions organized and co-sponsored by O-RAN ALLIANCE to allow environment friendly progress of the O-RAN ecosystem via well-organized testing and integration. Distributors and suppliers come collectively to check, consider and confirm their merchandise and options. The O-RAN ALLIANCE International PlugFest Fall 2023 was held in 16 labs throughout eight nations. One in every of these occasions was hosted on the i14y Lab in Berlin – supported by Deutsche Telekom and EANTC and i14y consortium companions. There, know-how distributors like Analog Units, Inc. (ADI) had the chance to confirm the conformance of their platforms with check and measurement options from Rohde & Schwarz and VIAVI Options amongst others.
To handle a number of software eventualities, ADI has developed a very versatile O–RU reference design. The ADI Kerberos O–RU (ADRV9040-RD-RUMB) 8T8R O–RU reference design and growth package helps time division duplex (TDD) in addition to frequency division duplex (FDD) modes up-to eight carriers (8CC) for all FR1 bands from 600 MHz as much as 6 GHz. As well as, it features a full O-RAN Cut up 7.2 x each for 4G and 5G NR requirements.
The setup used on the O-RAN PlugFest on the i14y Lab to validate ADI’s Kerberos O–RU consisted of the next check options:
- The R&S SMM100A vector sign generator and R&S FSVA3000 sign and spectrum analyzer from Rohde & Schwarz emulated a real-world radio surroundings by producing, capturing and analyzing RF alerts. For in-depth debugging R&S VSE vector sign explorer evaluation software program was used permitting to entry detailed measurement outcomes.
- The TM500 O–RU Tester from VIAVI Options has carried out the O-DU aspect of the M-plane and C/U-plane performance which was crucial for the configuration of the interface with the O–RU and to alternate I/Q information over the Open Fronthaul.
- The O–RU Take a look at Supervisor software from VIAVI has supplied a single level of management for the built-in system and has ensured a seamless, totally automated consumer expertise all through the check setup.
On the i14y Lab PlugFest, this check platform evaluated varied aspects of the ADI O–RU together with its conduct, adherence to protocol requirements, and compatibility with O-RAN ALLIANCE tips. This included the management and consumer aircraft (CU-Airplane) for each FDD and TDD modes of operation. As well as, the setup supported check circumstances from 3GPP TS 38.141-1 Base Stations (BS) performed conformance transceiver testing. The assessments have been executed underneath following circumstances:
- TDD: RF: 1×100 MHz CC; SCS: 30 kHz; Frequency band: DL/UL@3.8GHz
- FDD: RF: 1×20 MHz CC; SCS: 15 kHz; Frequency band: DL 2.64203GHz and UL: 5.52203 GHz
Rohde & Schwarz helps to drive growth, deployment and operation of Open RAN networks with its large portfolio starting from cellular community infrastructure tools verification via conformance to cellular community testing and benchmarking.
Alexander Pabst, Vice President of Market Section Wi-fi Communications at Rohde & Schwarz, says: “Open RAN is having its second now. Giant O-RAN deployments are deliberate in a number of areas all world wide. Open RAN pioneers like ADI require subtle O–RU check options to confirm the conformance and interoperability of their designs in a disaggregated multi-vendor community. The i14y Lab in Berlin is a fruitful collaboration house for testing, harmonizing and validating Open RAN options and we’re proud to be a consortium accomplice of i14y Lab.”
Stephen Rent, Vice President of Wi-fi Advertising and marketing at VIAVI, says: “For community operators to realize confidence to deploy O-RAN tools extensively, they should verify that there aren’t any interoperability points, and that the efficiency of the radios is nearly as good or higher than conventional options. We’re proud to have had the chance to work with our companions Rohde & Schwarz and i14y Lab to assist confirm the capabilities of the ADI reference design to allow them to realize an necessary milestone within the commercialization of O-RAN know-how”.
