Nokia Seizes Open RAN Initiative as Ericsson Holds Back

The upside of the open RAN
That seems unlikely to change soon. Quizzed about openness and possible membership of the ORAN Alliance, Ericsson responded with the following statement: "We welcome all discussions around openness. However, we have currently no public statement on the ORAN Alliance. We are in continuous contact with our operator customers and other shareholders in the industry, also the ones currently associated with ORAN, to ensure we continue to develop the right products that make operators successful in their markets and satisfy their end users' needs in the best way possible."

In this context, to say Ericsson is entirely opposed to openness would be going too far. "It is committed to open standard interfaces and rightly points to interfaces defined in 3GPP as what the industry has agreed," notes Gabriel Brown, a principal analyst with Heavy Reading. "In 5G this was settled only a year or so ago." When it comes to the ORAN Alliance, the stumbling block for Ericsson could be the all-important CPRI interface, which is not a 3GPP standard, says Brown. But Ericsson is hardly the only big vendor that stands outside the ORAN Alliance: China's Huawei, the other member of the global equipment triumvirate, has also steered clear. Nor is Huawei Technologies Co. Ltd. a member of TIP.

Even so, Nokia appears to see less threat, and perhaps some upside, in open RAN technologies. The explanation for that could lie in some of the aforementioned differences between Ericsson and Nokia. For one thing, with its broader portfolio of network equipment, Nokia is not as dependent on the mobile market as Ericsson, and therefore assumes less risk with a radical new approach.

Nokia might even see RAN virtualization and openness as an opportunity to be disruptive. "It's fair to say that some of the senior RAN architects and systems designers at Nokia have a long-standing interest in the idea of the programmable RAN," says Brown. He points out that open RAN technology could have a positive story for the industry. "Yes, open RAN can, in principle, help to radically reduce cost per bit, but it can also accelerate the rate at which innovative radio technology can enter commercial networks, which is just as important."

In the meantime, there have been suggestions that Nokia currently trails Ericsson and Huawei on mainstream RAN capability. Although Nokia would undoubtedly refute that charge, it managed to lose a long-standing contract with Deutsche Telekom in late 2017, when Ericsson displaced it as a RAN vendor in Germany. Again, this could drive Nokia toward open RAN and virtualization technologies as a way of reclaiming the initiative. (See DT Ditches Nokia From Its German Radio Access Network.)

Nokia's takeover of Alcatel-Lucent in early 2016 may have brought some cultural change, too. With their strong software capabilities, chunks of Alcatel-Lucent could form the building blocks of a profitable, standalone software business in future, reckons Nokia. This software mindset seems bound to influence attitudes across the entire organization, including Nokia's willingness to embrace new software-based RAN technologies. (See Nokia: Software Plan Already Boosting Profitability.)

Ericsson has good reason to be warier. Struggling to restore profitability after reporting operating losses in the last five quarters, the Swedish company is in a more precarious state than Nokia. For senior managers and shareholders, the priority is a return to what Ericsson does best, not experimentation that might ultimately backfire. And if Ericsson is to break with convention, the capable but unflashy Börje Ekholm, who took charge of the business in early 2016, does not seem like the man who would do it. (See Ericsson: Desperately Seeking Profitability and Ericsson Stuck in Loss-Making Rut, Offloads Majority Stake in Media Unit.)

Still, Nokia's dalliance with TIP and the ORAN Alliance hardly portends a dramatic reinvention of the Finnish supplier. Nor is there an immediate threat to Ericsson. For all the interest in RAN virtualization, some major operators have yet to be convinced of its benefits. As those become clearer, the danger for Ericsson is that hesitancy or unwillingness to change leaves it on the outside of the open, virtualized RAN.

Vergiss die Deutschen nicht Nokia "is a Frankenstein's monster of Finnish, French and US parts" 

- don't forget Siemens.

5G though? Ericsson seems to have the edge in deals there, early days of course...
