11 companies innovating in private cellular

The interest in private LTE and 5G networks has skyrocketed. Enterprises who have historically relied upon Wi-Fi connections or public cellular spectrum can now take full control over their systems and optimise their network. With more and more industries looking at the potential value of private cellular, we highlight some of innovative companies set to disrupt the dominance of the traditional players within the ecosystem. 

#1 Edzcom

Edzcom is provider of private wireless solutions based in Finland. The company, formerly known as Ukkoverkot, is now a Cellnex company after an acquisition in mid-2020. Edzcom is one of the most active private cellular network operators in the Nordic region and is already well established in a number of industrial sectors, particularly in port services, boasting customers like Finnish ports of Oulu, Kokkala and HaminaKotka. The company states its belief that it is better positioned to provide for the specific needs of enterprises, “serving specific market segments that require different solutions than the standard offerings of the traditional large operators”.

In the second half of 2020, Edzcom announced a partnership with lighting supplier Signify to introduce Trulifi, a two-way wireless network connection using light li-fi technology. In line with STL Partners’ proposition that enterprise network providers should prioritise diversified network offerings, Edzcom believes this is part of the innovative service it can offer to its “global customer base” (Mikko Uusitalo, CEO of Edzcom).

Its international aspirations have seen it broker an agreement with V&M Telecom, giving the former access to the 40 MHz of 3.5 GHz TDD frequency license (LTE band 42) that V&M Telecom uses to operate in the Netherlands. This newly branded firm plans to expand further into France and the UK via government sales of spectrum allowance.

#2 Ambra Solutions

Ambra Solutions is another leader in providing private wireless connectivity, offering a varied portfolio of LTE, satellite, mesh, two-way radio and more. The Canadian company offers especially tough designs for the more removed client who requires connectivity across large areas in remote locations. The company has recently purchased 8 further spectrum licenses from the Canadian government, expanding the areas of Canada to which it can offer services.

This expansion has greatly increased the number of industrial sites it can now service, including over 100 open-pit mines. Last year it deployed an LTE network at Tacora Resources’ Scully iron ore mine in Labrador, Canada. With only 2 fixed LTE transmission sites, the network covers the 15km2 mine and has facilitated a new fleet dispatch system, connecting the mine’s vehicles on one, secure network. As LTE also transmits voice, the network has eliminated the need for an additional VHF or UHF system.

#3 Challenge Networks

Challenge networks is an Australian provide full turnkey solutions with partners Nokia and Cisco. The organisation boosts experience in both the design and construction of LTE, UMTS, GSM and WCDMA Mobile networks alongside fixed network capabilities. Its in-house specialists provide expertise in Layered & Non Layered Architectures (Soft Switch, Media Gateway IP and Multimedia), Packet Switching, Intelligent Networks and more.

Challenge Networks boasts operationally successful deployments supporting Modular and Caterpillar Fleet Management (FMS) and Autonomous Haulage System (AHS) applications, as well as Autonomous Drilling Systems (ADS) for mining locations. Its private LTE deployments for Rio Tinto at Paraburdoo, Nammuldi, and Silvergrass form a part of its active portfolio which continues to grow within the resources sector. It also offers a migration programme for clients wanting to move from Wi-Fi networks onto private LTE, an offering which it views as a growing portion of work.

#4 Anterix

Anterix is a US based operator, primarily focused on delivering private LTE solutions to the energy, transport and logistics sectors. In 2020, Anterix created a secure broadband allocation within the 900 MHz segment with the FCC. By providing licenses or leases for the use of this allocation, Anterix is facilitating mission-critical functionality of private networks for utilities and enterprises.

Earlier this week, Anterix announced a $50 million deal with San Diego Gas & Electric to provide the license for its broadband allocation, forming the foundation of smart-grid and wildfire mitigation initiatives. The private LTE network will be particularly powerful in the latter where Anterix CEO Rob Schwartz believes the ability to proactively locate and de-energize failing powerlines will be a critical asset to the company.

#5 Tampnet

Tampnet provides connectivity for offshore systems, particularly the oil, gas, and wind industries. Offering both subsea fibre optics and private 4G LTE, the provider enables high-capacity connection even in the roughest weather. Its LTE network solutions allow moving assets to connect to static rigs whilst also providing coverage on-asset to ensure the complete connectivity of the system. Tampnet’s partnership with Darktrace for its Cyber AI Platform provides a mission-critical layer of security for these offshore companies. The self-learning software is able to detect deviations from normal organisational traffic and isolate cyber-threats before they become dangerous.

In 2018, DeepOcean, a subsea service provider, was brought on by an Oil company for ROV and maintenance. DeepOcean asked Tampnet to upgrade its VSAT connectivity to 4G LTE so that previously arduous communication and monitoring tasks could be done seamlessly. As well as enabling real-time overwatch of subsea operations, the Tampnet network also ensured the cost and time efficiency of operations.
