For years huaweis biggest rivals in the telecoms equipment market finnish group nokia and swedens ericsson were based far away from the shenzhen-headquartered group.but now a credible challenger looking to tap into the once in a decade global race to deploy 5g has emerged closer to home: samsung electronics.

The seoul-headquartered group has long lagged behind its global peers when it comes to providing telecoms kit. in the minds of investors and analysts, samsungs struggling network business has been a distant afterthought to its core revenue drivers of computer chips, smartphones and displays.

However there are growing signs that the group is finally poised to make meaningful inroads, boosted by the confluence of 5g rollouts across the world and intensifying pressure from governments of us allies to block huawei, the sectors biggest player, from their networks.

Samsungs progress was underscored in september when it picked up its biggest 5g deal to-date: a $6.6bn contract with us group verizon to supply 5g radio access network (ran) equipment to the us operator until the end of 2025, boosting its credibility as a serious contender in the network business.

Samsungs recent win with verizon could be a game changer, said stefan pongratz, a 5g expert at research company delloro group.

Huawei, ericsson and nokia still dominate the global network equipment market, collectively holding a 70 per cent to 80 per cent share according to estimates. but samsung is gaining ground.

In the overall telecom equipment market, which includes earlier iterations such as 4g, samsungs market share has roughly doubled over the past two years to about 3 per cent, according to delloro. but in the new market of 5g mobile infrastructure, its market share by the middle of this year was in the 10 per cent to 15 per cent range.

Samsung, which declined to comment for this article, is already capitalising as countries ramp up 5g investment. outside south korea, where it is the biggest player in 5g network equipment, it has won deals in the us with sprint, at&t and us cellular, and with kddi in japan, telus and videotron in canada and spark in new zealand.

The race to deploy 5g the worlds fifth generation mobile network, touted as pivotal to advancements in industrial automation, driverless cars and the internet of things is expected to spur annual investment averaging more than $235bn through to 2035, according to ihs markit. the us and china are each forecast to spend more than $1tn in 5g-related capital expenditure and research and development over that 16-year horizon.

We are very much at an early stage in the 5g era, said ian fogg, lead analyst at uk research group opensignal. there still is a lot to play for.

Pressure from the trump administration on huawei including moves to limit sales of critical technology such as chips to the group has sparked reviews in many countries over their reliance on kit from the chinese group, both for core networks and the hardware such as base stations and antennas that make up ran, which connect devices to those networks.

According to delloro data, telecoms operators in at least 14 countries are currently reassessing or reviewing their reliance on huaweis ran portfolio, including equipment across 2g, 3g and 4g. the countries, which include australia, brazil, germany and the uk, account for about one-third of the global ran market.

Ericsson, nokia, and samsung have all benefited from the escalating geopolitical uncertainty, said mr pongratz.

Given the questions over huaweis ability to access key technology and foreign markets, a key selling point for samsung is its secure supply chain. the groups 5g business has little exposure to china, instead manufacturing its network equipment in south korea and vietnam while producing other key components, such as its 5g modem chip, in the us.

Samsung is accustomed to fighting for the top place in worldwide tech rankings be it in appliances, computer chips, smartphones or electronic displays but its telecoms business is comparatively small.

While the company has been developing related technology for more than 40 years, several earlier attempts to grow its network business were scuppered after it focused on a series of wireless technologies that quickly became obsolete.

Woojune kim, the head of global sales at samsungs network business, told an uk parliamentary committee in july: you could say that we placed our bet on the wrong horse.

In recent years the group has intensified its focus on 5g, spending more on research and taking a keener role in the development of the industry standards and protocols that apply to new network technology. at the start of the year samsung trailed only huawei in declared 5g patents, according to intellectual property group iplytics. problems faced by nokia with the quality of its products in the initial stages of 5g have further buoyed the group, analysts said.

But competition will be fierce as companies compete for trillions of dollars in investment.

Mr fogg noted that previous changes in network equipment technology which occur roughly once every 10 years and require sharp increases in capital expenditure have typically sparked periods of upheaval as telecoms groups switch equipment suppliers, companies consolidate and erstwhile incumbents fall by the wayside.

Choosing 5g equipment suppliers is not a simple equation, he said. you have to basically make a judgment call about their future. you have to think about the reliability of the life of the contract.

Some operators swapping out legacy huawei equipment might favour ericsson and nokia because they, unlike samsung, are more readily able to supply equipment from 2g through to 5g, analysts suggest. this leaves the european groups very well positioned to win opportunities in countries ditching huawei, said mr pongratz.

Last week it was announced that nokia will become bts largest supplier after it won an expanded deal to replace huawei as a key supplier of 5g equipment to the uk company.

Samsungs counter is that there is little benefit from having a single ran, arguing it is faster and no less secure for network operators to overlay 4g and 5g technology on legacy 2g and 3g networks.

Another criticism levelled by analysts is that samsung, traditionally focused on manufacturing hardware, has suffered from a weak services offering as part of its network business, hindering its capacity in areas such as network design, testing, optimisation and software.

According to people close to the company, it has made moves to remedy this, acquiring teleworld solutions, a virginia-based network services provider, in january this year, and launching a hiring spree for its services team.

So far, samsungs 5g business has targeted network operators mostly in advanced economies, particularly in asia, western europe and north america.

The company also believes it is strongly positioned in india having won an earlier contract to build the 4g network for reliance jio, indias biggest network, despite a broader push by new delhi to use homemade technology.

These are also mostly markets where there is pressure on governments to block huawei because of lingering fears over the companys links the chinese government and military, and concerns that its technology could be used for spying. huawei has denied such allegations.

But that still leaves huge swaths of the global market, including many emerging economies, where governments have shrugged off the us concerns.

Samsung, nokia and ericsson face the prospect of competing with the chinese group in africa, where huawei has built a dominant position across much of the continent, according to analysts.

Huawei already operates at almost every level of internet provision on the continent, from installing undersea cables to selling handsets, said cobus van staden, an expert on china-africa relations at the south african institute of international affairs in johannesburg.

Pricing is another factor. in open markets with fairly healthy competition we dont believe the prices vary significantly for ran equipment among the top suppliers, mr pongratz said, but he added that costs will vary depending on the region and how competitive those looking to build their market share will be.

Samsung has signalled that there are markets where it cannot compete with huawei.

They are just a very tough competitor. when you go into bids, we have frequently seen bids that do not seem to make sense in the pricing, mr kim said in july. we think that a company that was beholden to shareholders and had to make profits could not offer that sort of bid.
