On the frontier of innovation: Nemont Telephone Cooperative celebrates 75 years in Big Sky Country
Formed by necessity and guided by community, Nemont is a trusted symbol of what it means to stay connected in rural Montana.
Out in northeastern Montana, where towns are tight-knit and distances are measured in hours, connectivity isn’t just a convenience—it’s a lifeline. For 75 years, Nemont Telephone Cooperative has been that vital link, connecting homes, schools, hospitals, businesses and ranches. From party lines strung along fence posts to today’s fiber-optic broadband and wireless towers, Nemont’s journey is a tribute to rural resilience and the enduring power of community.
When local goes global
Nemont’s story begins in 1950. Frustrated with unreliable service and lines that were often nothing more than wires strung along barbed fences, a group of rural Montanans took action. They formed the Northeastern Montana Telephone Cooperative Association, a grassroots effort to take communication into their own hands.
The region celebrated a major milestone just four years later: the arrival of eight-party dial telephones. The excitement was so palpable that even a US Senator attended the dedication ceremony. That same year, a new office rose in Scobey, setting down the roots of what would become a rural telecom powerhouse.
By 1957, the cooperative streamlined its identity with a new name: Nemont Telephone Cooperative, Inc. As the decades passed, the company stayed ahead of the curve, moving from locally printed phone books and early computerbased billing in the ‘60s to single-party phone service in the ‘70s. Through every advancement, Nemont remained guided by a singular purpose—to bring people together, no matter how remote.
Expanding horizons in Big Sky
Nemont’s growth was steady and strategic. In 1978, it acquired Project Telephone Company in Worden, later expanding to serve communities like Huntley, Belfry and Absarokee. Nemont didn’t stop at phone lines. Its cable TV venture in the ‘80s and launch of Nemont Communications Inc. marked early forays into multimedia, followed by dial-up internet in 1996 and broadband rollouts in the early 2000s.
When the need for mobile service surged, Nemont answered with Sagebrush Cellular, a subsidiary that now operates 114 cell sites across northeastern Montana. Partnering with other rural cooperatives also helped found Vision Net, bringing interactive TV to regional schools, hospitals and businesses, bridging digital divides with homegrown grit.
A celebration 75 years in the making
Nothing better illustrates Nemont’s value to the communities it serves than the overwhelming success of its 75th Annual Meeting of Members. What’s traditionally a modest gathering turned into a full-blown celebration with nearly 600 attendees, some driving more than two hours to take part.
Held inside Nemont’s vehicle garage, transformed into a community hall for the day, the event featured local fare, a side-byside utility vehicle giveaway, kids’ prizes like a PlayStation and $75 bill credits for each registered member attending the event. But what truly stood out wasn’t the prizes; it was the people.
“This 75th anniversary marks a significant milestone in our journey,” said Leif Handran, Senior Sales & Marketing Manager. “It’s a moment to honor the legacy of those who came before us, celebrate the progress we’ve made and look ahead with renewed purpose and commitment to the future.”
“What struck me most,” said Ericsson Sales Director Benoit Coulombe, who experienced the event firsthand, “was how deeply Nemont is woven into the fabric of the community. They support the schools, libraries, hospitals, first responders—they’re not just a provider, they’re the connective tissue that holds the region together.”
As the crowd grew, so did the need for more chairs and tables. That’s when the local community center stepped in. Trucks were dispatched, furniture was hauled and Nemont staff and attendees pitched in without hesitation.
“It wasn’t a typical event with one person running the show,” Coulombe recalled. “Everyone just helped. Someone noticed the chairs were low and took the initiative to get more. Employees were serving food, solving problems—it felt like family.”
In a town like Scobey, population just under 1,000, pulling in nearly 600 attendees is no small feat. But Nemont isn’t just a company headquartered in Scobey—it is Scobey, Glasgow, Poplar and more than 30 other communities it serves.
The power of local ownership
At the heart of Nemont’s longevity is its cooperative structure. Each member is an owner, and every year, the Meeting of Members isn’t just a celebration; it’s a working democracy. Peers, not shareholders, elect board members. The board makes critical decisions on infrastructure, strategy and spending—decisions that impact real people in real places.
“You really get an understanding of how important it is for this community to have a strong communications provider,” Coulombe emphasized. “Without Nemont,
things would be really difficult. Everyone from the ranchers to the local restaurant owners relies on them.”
Looking ahead, staying grounded
As it marks 75 years, Nemont isn’t slowing down. The company continues to invest in fiber infrastructure, expand wireless coverage and advocate for rural broadband equity on the national stage. Yet it remains grounded in cooperative values:
• Voluntary and open membership
• Democratic member control
• Member economic participation
• Autonomy and independence
• Education, training and information
• Cooperation among cooperatives
• Concern for community
From telephone etiquette classes and job shadowing opportunities to millions in E-Rate subsidies for schools and libraries, Nemont remains not only a service provider but a pillar of local development.

Impact of GenAI on mobile network traffic
Generative AI (GenAI) may significantly impact future mobile network traffic, particularly through increased video consumption and changing uplink requirements. To help service providers prepare, Ericsson explored how GenAI will change traffic volumes or characteristics from previous mobile broadband and extended reality (XR) predictions.
GenAI refers to advanced machinelearning models that understand text, audio and video context based on patterns learned from vast datasets. Understanding context allows it to create new information, often indistinguishable from humangenerated content, and to segment and represent provided content through more efficient encoding.
Understanding GenAI
Users engage with different forms of content, including audio through headphones, text and video through smartphones and 3D objects and volumetric environments through immersive XR devices. Each is being impacted by GenAI capabilities, where these fundamental approaches have emerged: generative adversarial networks (GANs), diffusion models, transformers and hybrids thereof. Transformers—powering large language models (LLMs), such as current GenAI chatbots—are neural network architectures originally designed for sequential data, like text, using self-attention to capture data dependencies. Increasingly used for multimedia tasks, including audio, image and video generation, they are highly effective at capturing “long-range dependencies” and are particularly powerful for “multimodal tasks,” such as text-to-image generation.
These techniques collectively form the backbone of GenAI, pushing the boundaries of what machines can create in terms of images, videos, 3D objects and more. Of importance to mobile networks is insight into where these models will likely be executed, as summarized in Figure 1.
Introduction to semantic compression
GenAI models can also represent content more efficiently as they can understand context. Imagine a high-resolution safety
camera, recording millions of pixels of detailed information, capturing a person operating a machine. Rather than trying to understand each pixel, an alternative approach is to describe features in the photo, for example, the operator’s hair color or how the machine is handled.
Referred to as latent space, the exact pixel details are lost, but the essential characteristics that define an entity’s appearance are preserved in compact data representations. Generative models have extremely capable inference properties that allow them to synthetically render the entity based on these representations, thus reducing bandwidth requirements.
Providing a higher resolution or reducing the bandwidth needed per stream helps improve the user experience by enabling new applications that may not have been possible in constrained situations.
The processing capabilities and standards required to do this at scale for consumers could be a decade away. However, it could be used in a proprietary form in closed ecosystems or volumetric/ avatar content representations and synthetic regeneration. General adoption and scale of semantic compression remain uncertain. This technology is expected to be part of the evolution of video compression technologies.
Trends in consumer interactions with GenAI
Users will increasingly consume and produce GenAI content and interact with multimodal GenAI models using smartphones or XR devices. Initially, consumers will initiate these interactions; however, toward the end of the decade, instances of AI-based assistants acting on behalf of consumers will likely rise.
Figure 1: GenAI model complexity and execution location
AI-based assistants use AI agents, systems that use GenAI to achieve specific goals autonomously. They can help with healthcare, education, understanding and reacting to users’ environments and more. While intelligent voice-based assistants are commonplace, advances in GenAI are starting to enable video-based assistants. Most of the traffic increase will be due to video-based GenAI interactions, where three areas are emerging:
• Viewing hyper-personalized content through the legacy way of using a smartphone screen—for instance, educational or entertainment materials are catered to a specific person, significantly increasing engagement and retention rates.
• Using the smartphone camera to look around and ask a video LLM about the immersive environment—for example, pointing the camera at a car engine and receiving step-by-step repair instructions.
• Using smart glasses or XR devices to engage with the environment on an as-required basis initiated by the user or via an always-on AI agent monitoring the immersive environment—for instance, the AI assistant could use a video LLM via smart glasses to recognize food on a plate and calculate the nutritional value. The wide use of such assistants could imply growth in uplink traffic from current levels.
Similar to today’s text-based interactions with GenAI chatbots, other interactions between consumers and GenAI models will emerge. Since these engagement
modes are not expected to increase traffic significantly, they are not considered here. Beyond the consumer segment, we expect increased traffic from AI agents interacting with drones and droids.
Impact on mobile network traffic
Evaluating these factors provides valuable insights into potential traffic patterns. The effects will depend on several variables, such as consumer interest and industry uptake, which will become apparent over the coming years. Consequently, this qualitative analysis aims to offer insights into possible future developments in traffic volume.
GenAI workloads will mainly be executed in the cloud in real time or prerendered to generate hyper-personalized content users consume when needed. Some mediumcomplexity GenAI workloads currently executed in the cloud will likely migrate to the smartphone, enabled by low-complexity LLMs. Complex real-time engagements will likely be orchestrated in a federated fashion: Simple sub-tasks are completed on smartphones, more complex but privacyprotected tasks in a private (edge) cloud and highly complex tasks by the large LLMs in the cloud.
As a result, uplink versus downlink requirements will change toward the end of the decade. Due to hyper-personalized content, further increases in downlink traffic over the baseline may occur. A significant rise in uplink traffic due to consumer- or AI assistant-initiated video streams may also occur if GenAI-enabled devices reach mass market volumes. For instance, using smart
glasses with an AI-based video assistant for just an hour a day would substantially increase traffic.
The projected rate increase is potentially offset per flow by emerging GenAI capabilities, such as semantic compression, on-device AI-based upscaling or on-device search enabled by up-to-date LLMs. Such sophisticated GenAI capabilities in smartphones will have very high compute, memory and battery requirements. Thus, uptake will depend on industry roadmaps for device hardware and embedded GenAI model software.
These and other GenAI capabilities will likely drive new applications, scale existing ones and improve the user experience. As a result, GenAI could cause overall traffic. Illustrated in Figure 2, three potential future traffic trends could emerge:
• Future #1: Despite recent signs of general traffic growth in developed markets slowing down, the GenAI adoption at scale may be a reason for a continued traffic increase.
• Future #2: Accelerated consumer uptake of GenAI will cause a steady increase in traffic beyond the baseline increase.
• Future #3: GenAI consumer uptake will explode—possibly aligned with the launch of AR glasses. The industry will be forced to consider more efficient video compression technologies, including the potential introduction of semantic compression—at least for parts of GenAI traffic— to deal with this. These viable alternatives and general traffic saturation may cause traffic to stabilize.

Steve Lowe Director of Utility Sales, Ericsson
Q: Why is there growing momentum for private LTE in utilities?
A: The growing adoption of private wireless networks in the utilities sector is driven by the need for greater operational efficiency, enhanced reliability and resiliency and a shift toward capital-focused investment strategies that reduce ongoing operational expenses. To boost revenue and minimize costs, utilities are emphasizing efficient energy use and realtime connectivity for more effective grid management. This transformation is further accelerated by EV charging and DERs, which introduce new requirements that fall outside the current real-time visibility of traditional utility systems.
Initial wireless use cases include:
• Supervisory control and data acquisition (SCADA)
• Grid-scale DER integration (renewables, batteries)
• Replacements for or complements to existing land mobile radio systems
Spectrum availability
Utilities struggle to compete in public spectrum auctions due to the high ROI required to outbid commercial carriers. However, utilities now have access to utility-focused spectrum options, including 900 MHz (Band 106) from Anterix, CBRS and Band 26, offered through T-Mobile/Grain 1. While deploying private
networks on these bands still requires a significant investment, an increasing number of utilities are finding the benefits worth the cost.
Successful deployments
Many utilities prefer not to be the first to deploy new technologies but are eager to be second to avoid falling behind their competition. Successful deployments at Southern Linc, Evergy and Ameren provide a point of reference as utilities work through internal and regulatory approvals.
Funding
Investor-owned utilities (IOUs) operate as monopolies in their regions and are regulated at federal and state levels. Any significant investment must undergo a rigorous approval process. IOUs are generally encouraged to invest capital in infrastructure rather than increase operational expenses. Private wireless networks offer lower long-term costs and give utilities greater control over reliability and resiliency.
Utility devices
Off-the-shelf customer-premises equipment often falls short of utilities’ specialized needs. However, the availability of Band 106 spectrum and a growing number of utility deployments have created enough demand to justify manufacturer investment in purpose-built devices. In the case of Band 26, leadership from utilities like Southern Linc has already helped establish a mature device ecosystem. As private wireless technology evolves, it provides a standardsbased, future-ready solution that can scale to meet today’s operational needs and tomorrow’s growing demands.
Evolving the security posture for critical infrastructure
5G is critical infrastructure that provides the foundation of society, supporting economies, public safety, healthcare, utilities and our everyday lives. Maintaining the security of this infrastructure is becoming increasingly challenging due to the evolution of advanced persistent threats (APTs). Network operators, as well as the hardware and software suppliers of those networks, should assume the adversary is already in the network—because they are.
The challenge
The challenge to secure against APTs is that the external threat actor penetrates through a secure perimeter to become an internal threat actor able to persist and move laterally through the network. This challenge is exacerbated in a multistakeholder deployment, where there could be varying security postures and unclear assignment of responsibilities. Increased due diligence is needed to secure critical infrastructure in open, cloud-native, multivendor deployments.
The response
The telecom industry was already on its path to building secure networks to protect our nation’s mobile critical infrastructure from sophisticated attacks, and recent APT attacks have strengthened the industry’s resolve. The best defense against APTs is to build in security using a multipronged approach based on guidance from US federal agencies:
1. Implement Zero Trust Architecture (ZTA)
ZTA, introduced by the National Institute of Standards and Technology (NIST) in 2020, is a network characteristic that should be implemented end-to-end to eliminate any weak point of entry that can serve as a beachhead to the rest of the network. The primary strength of ZTA is that it protects
against external and internal threats as if the adversary is already inside. The US Department of Homeland Security (DHS) and the Cybersecurity and Infrastructure Security Agency (CISA) recommend that operators and their suppliers follow the Zero Trust Maturity Model, which implements ZTA in four incremental stages.
2. Follow secure software development processes
Reducing software vulnerabilities with secure software development can mitigate the threat of APTs exploiting vulnerabilities once inside the network. Secure software development best practices have been made publicly available by the Business Software Alliance (BSA), the Open Web Application Security Project (OWASP) and SAFECode. A fundamental practice for secure software development is to have secure consumption of thirdparty software, particularly Free Open Source Software (FOSS) that often is not maintained to be secure.
3. Apply industry best practices for hardening
APT exploitations can be mitigated through vulnerability patching, password hygiene and configuration hardening. Configuration hardening is achieved in two steps: first plan and set the security baseline configuration and then continuously audit for security configuration changes and drift. It is fundamental to maintain the security
baseline and necessary to have visibility into any configuration changes that deviate from the baseline. Identity and access management configuration should be a high priority as it is a common attack vector. CISA has provided excellent hardening guidance for securing products, as has the US National Security Agency (NSA).
4. Continuously monitor for visibility
Because APTs appear as internal threat actors, it is necessary to have end-to-end visibility through continuous monitoring of the network, workloads and users. A security management system for operations provides the ability to identify, protect, detect, respond and recover from evolving internal attacks on the microperimeters of each network asset and cloud-native infrastructure. Visibility through continuous logging of access attempts and command execution can leverage AI-based security to enable realtime detection of anomalous behavior and the presence of APTs inside the network.

Ghoshal, Global Head of Mission Critical Networks for Utilities
Why are utilities moving to mission-critical networks?
Utilities rely on connectivity to support wide-ranging smart grid devices with different performance requirements. Some need low latency and instant response, while others, like smart meters, transmit data at intervals. To manage the different latency, speed and response requirements of various use cases, utilities use multiple proprietary non-LTE networks tailored to specific devices. While this approach ensures that each network operates with the desired performance, it results in a complex and decentralized web of networks.
This article highlights how mission-critical (MC) LTE networks enable utilities to deploy a single network that supports broadband and narrowband connectivity, addressing all use cases regardless of latency, throughput or coverage needs.
Why mission-critical LTE matters for utilities
Public communication service provider (CSP) networks often lack backup systems and prioritize 5G. Utilities prefer private networks because they allow control over communications during power outages and flexibility for network upgrades. Additionally, the device ecosystem for utilities is robust in established technologies like LTE. Thus, utilities are building LTE networks while they wait for the 5G device ecosystem to mature. As utilities transform their power grids to address major challenges, mobile communication networks are playing a key role in these areas:
• OpEx reductions: A single, multipurpose 3rd Generation Partnership Project (3GPP) standardsbased network with a well-established, diverse ecosystem of devices enables utilities to streamline operations.
• Grid security: As cyber and physical threats grow, mobile networks offer secure, reliable communication channels, ensuring grid stability and providing backup options during disruptions.
• Workforce challenges: With a shortage of skilled workers, utilities are exploring augmented and virtual reality, digital twins and AI. Mobile communications enable these technologies, enhancing support for field staff and improving operational efficiency.
• Digitalization and decentralization: Mobile networks can support grid optimization, reduce outages and enhance performance by enabling new digital services that improve grid resilience, stability and cost-efficiency.
• Sustainability: Utilities are shifting to decentralized grid architectures to integrate more renewable energy sources, which require robust mobile communications like MC LTE and 5G for real-time monitoring, control and management of distributed power generation.
Private MC LTE networks offer greater communication resilience than standard LTE, which is crucial for critical
infrastructure providers. Since public LTE networks already cover most areas, including remote regions, they are integrated with private MC LTE networks to provide a critical fallback option for ensuring continuous coverage.
MC LTE networks enable the creation of secure networks that meet business and mission-critical application requirements. This standardized, scalable technology is becoming the mainstream solution for IoT, especially when it is enhanced with support for Narrow Band-Internet of Things (NB-IoT) and Long Term Evolution for Machines (LTE-M). Security measures such as encryption, access control and user and device authentication are integral to the LTE standard, with 5G offering even greater security improvements over LTE.
What utilities need from their networks
High reliability and strong communication security are essential for all utility use cases. Most require “four-nines” availability, allowing less than five minutes of downtime a month.
Devices like sensors and actuators, which support grid automation, are spread
Utilities’ key drivers supported by mission-critical networks
across large areas, sometimes up to 100 square kilometers. The density of these devices in power networks varies depending on the specific use case and deployment architecture. In most utility use cases, distribution networks use more devices than transmission networks.
Private LTE networks are well-suited for use cases with medium- to highlatency tolerance. In contrast, low-latency applications will require advancements in LTE, 5G or alternative technologies such as microwave transport. In most data-oriented use cases, the volume of transmitted data is relatively small, typically measured in kilobits per second (kbps), with measurement data accounting for several hundred bits of the overall message. As these use cases evolve, the need to collect larger volumes of data at shorter intervals is expected to drive real-time enhancements in power grid performance.
As 3GPP cellular networks are deployed to achieve the utilities’ goal of wireless grid modernization, a growing set of application-driven considerations, such as device positioning and power consumption for device and application lifecycle management, will emerge.
Looking ahead
MC LTE networks offer a cost-effective foundation for today’s power grid communication needs while supporting evolving use cases with increasingly strict performance demands. While 5G networks address some current challenges in power grids, as the 5G ecosystem develops, it will support use cases such as instant-response protection systems, video surveillance and drone-based maintenance. The transition from LTE to 5G, guided by 3GPP standards and mobile network providers, is already in motion.
Integrating mobile networks into utility power grids is a long process. Private mobile networks offer the critical capabilities demanded by utilities: complete control over security and management. Private LTE networks are already deployed in some parts of the world, while in others, they are in progress or the planning stage. The experience gained through close collaboration between communication vendors and utilities during these projects has resulted in the creation of optimal solutions for the sector.

Connecting communities in crisis
Ericsson Response is Ericsson’s global humanitarian volunteer initiative, created to support communities in times of crisis through the power of connectivity. Since its inception in 2000, the program has grown into a dedicated network of over 150 skilled volunteers across more than 30 countries.
Ericsson Response has supported more than 60 humanitarian missions in 40 countries, providing critical communication services in some of the world’s toughest crisis zones. From natural disasters to complex emergencies and refugee crises, the program helps restore connectivity and enable an effective on-the-ground relief response.
In emergencies, every second counts. By working closely with government agencies and other international partners, Ericsson Response ensures a swift, organized and impactful deployment. This collaboration helps save lives, supports frontline teams and underscores the essential role of connectivity in humanitarian efforts.
The core mission of Ericsson Response is to provide information and communication technology (ICT) solutions in emergency situations. Committed volunteers deploy rapidly to crisis-affected areas, setting up and maintaining temporary mobile networks
Response in real time
In July 2024, Hurricane Beryl descended on the Caribbean islands as a Category 5 storm, causing widespread damage to several countries.
In Jamaica, our efforts focused on Black River, St. Elizabeth parish, where the municipal building complex became the focal point for coordinating disaster response. While the building infrastructure remained intact, the ISP fiber link was destroyed, leaving responders without reliable internet access. We implemented a creative approach to restore communication by utilizing high-speed satellite terminals, Ericsson Cradlepoint 4G/5G routers and Ericsson WiFi equipment. We also deployed our costeffective solar power solution to ensure continuous operation. Our setup enabled remote management of user traffic and equipment through Cradlepoint routers, providing essential communication services for a staff of 60 across multiple buildings. Ericsson Response continued to support communities and aid relief efforts for more than four months after Beryl struck.
and internet services. These critical communication systems enable humanitarian aid organizations to coordinate relief efforts more effectively and support the affected population until local infrastructure can be restored.
While emergency response remains a key focus, Ericsson Response increasingly emphasizes preparedness and resilience. Recognizing the growing need for communities to become more self-sufficient in the face of disasters, the program works proactively with partners to build robust systems that help mitigate the impact of future emergencies and improve overall response times.
With more than two decades of experience, Ericsson Response is a vital force in global humanitarian operations. Through ongoing training, global readiness and close cooperation with partners, the program acts quickly and effectively—bringing connectivity, hope and support to those who need it most.
