BOYCOM Cablevision, a rural Missouri internet provider, raised its average revenue per user (ARPU) by more than 20% using the Calix One platform, Calix, Inc. announced on October 29, 2026.

With more time for subscribers, the company raised its Net Promoter Score by 20 points in less than two years. BOYCOM has served its communities for more than 30 years.

Calix launches GigaPro managed switches to expand business and multi-dwelling unit services

Calix (NYSE: CALX) has launched three GigaPro managed switches, the GPS8P, GPS24P, and GPS10TP, on its Calix One platform. The company announced them on October 20, 2026, at its annual customer conference in San Jose, California. The switches let service providers match port density, Power over Ethernet capacity, and multi-gig performance to sites ranging from small businesses to large apartment communities. Providers can manage them alongside Calix Wi-Fi appliances and SmartLife experiences in one cloud-based system. Calix says providers are already growing with its SmartBiz and SmartMDU services. Alaska Communications raised SmartBiz adoption 193% after bundling managed Wi-Fi into small business plans. "Entering a new market should not require a service provider to build a new technology stack or operating model," said Shane Eleniak, chief product officer at Calix.

Launch of Calix GigaPro managed switches enables seamless business, MDU, and residential deployments to drive service provider growth.

Launch of Calix GigaPro managed switches enables seamless business, MDU, and residential deployments to drive service provider growth. Stock score locked: want to see it? Benzinga Rankings give you vital metrics on any stock - anytime. The new GigaPro managed switch portfolio gives providers more ways to pair managed switches with Calix appliances and SmartLife experiences, expanding the types of business, multifamily, and residential environments they can deploy in and manage through the Calix One platform Today, at its annual innovation and customer success conference, Calix, Inc. (NYSE:CALX) launched the GigaPro(R) GPS8P, GPS24P, and GPS10TP managed switches on the Calix One(TM) platform to support more SmartBiz(TM) and SmartMDU(TM) managed service deployments. By bringing Calix Wi-Fi appliances, managed switches, SmartLife(TM) experiences, and cloud management into one operating environment with Calix One, service providers can more easily scale across business, multifamily, and residential markets. The new GigaPro managed switch portfolio gives service providers the flexibility to match the port density, Power over Ethernet (PoE) capacity, and multi-gig performance to environments ranging from small businesses to multi-tenant offices and large apartment communities. Providers can manage each deployment through the Calix One platform. Service providers are already using SmartBiz and SmartMDU to grow into adjacent markets. Alaska Communications increased SmartBiz adoption 193 percent after bundling managed Wi-Fi into their small business plans, while Blue Stream Fiber recently activated hundreds of units in just 30 days and achieved a 4.99 out of 5 resident satisfaction score during their SmartMDU deployment. The new GigaPro switches build on that momentum by expanding the types of environments they can serve. GigaPro managed switches on Calix One help service providers: * Deploy the right managed infrastructure for the right environment. Pair the appropriate Calix appliances and managed switches based on port density, PoE capacity, and multi-gig performance to support diverse property needs and connected devices, from phones to security cameras and IoT devices. * Expand SmartBiz and SmartMDU into more properties. Leverage the expanded GigaPro managed switch portfolio to support new business, multifamily, and residential opportunities with faster, simpler deployments that reduce installation effort and configuration errors. * Manage everything through one platform. Provision, monitor, and manage Calix indoor and outdoor Wi-Fi appliances, switches, and SmartLife experiences in a single, carrier-grade, cloud-based environment without adding separate management systems for switches.

Calix customers receive tailored guidance to accelerate time to revenue, 24/7 support, and industry-leading training and certification. Ian Carmichael, product development and customer operations manager at NextLight, said: "As we expand our SmartBiz and SmartMDU offerings, we need infrastructure options that fit each deployment without changing how our teams operate. Having more networking options through Calix One helps us serve a wider range of properties while delivering the level of service our subscribers expect." Shane Eleniak, chief product officer at Calix, said: "Entering a new market should not require a service provider to build a new technology stack or operating model. By expanding the managed infrastructure providers can deploy with the Calix One platform, we are helping them support more businesses, multifamily properties, and homes while keeping operations simple and consistent as they grow."

Calix advances trusted, secure, and predictable AI at ConneXions 2026 with Agent Workforce innovations to enhance subscriber experiences and drive market expansion.

Calix advances trusted, secure, and predictable AI at ConneXions 2026 with Agent Workforce innovations to enhance subscriber experiences and drive market expansion. Building on the launch of Agent Workforce on the Calix One platform earlier this year, Calix is extending secure, purpose-built AI across the service provider business, from the employees who run it to the subscribers they serve, with greater control to govern and tailor AI to how they operate. Meanwhile, SmartMDU and SmartBiz advancements extend the Calix operating model into business and multifamily markets. SAN JOSE, Calif. - October 19, 2026 - Today, at its annual innovation and customer success conference, Calix, Inc. (NYSE: CALX) unveiled the next evolution of Calix Agent Workforce(TM) on the AI-native Calix One(TM) platform, alongside SmartLife(TM) advancements that expand market opportunities for service providers. Unlike generic AI tools that businesses must adapt and manage themselves, Calix delivers purpose-built knowledge, workflows, and governance through one platform designed around how service providers operate. Together, these innovations demonstrate how Calix is leading the industry to ensure service providers can operationalize AI across their business and subscriber experiences through a secure, trusted, and predictable operating model. As organizations race to deploy AI, service providers face a growing challenge: turning AI into measurable business value without introducing new complexity, or unpredictable costs. Calix has spent the last three years building the platform, workflows, governance, and ecosystem necessary to turn AI into measurable business outcomes for service providers. Today, more than 15 years and $2 billion of platform investment culminate in a new generation of capabilities that help service providers confidently leverage AI to fundamentally reshape how they acquire subscribers, grow value, build loyalty, and compete to win. At ConneXions 2026, Calix demonstrated how the Calix One platform combines communications-industry intelligence, orchestrated workflows, and purpose-built experiences to help service providers transform work, deepen subscriber relationships, and expand into new markets. These innovations bring that vision to life across subscriber experiences, business operations, and new market opportunities: * Subscriber Agent in the refreshed CommandIQ(R) mobile app brings conversational AI to the connected home experience, helping subscribers manage, optimize, and protect their home networks simply by asking for what they need. This personalized, intuitive experience makes everyday tasks easier while helping service providers reduce routine support demands, deepen engagement, strengthen loyalty, and stand apart in competitive markets. * New Control Center for Agent Workforce gives service providers a single, personalized experience for deploying AI across their businesses. Rather than navigating disconnected tools, teams can access the insights, recommendations, and actions most relevant to their roles through one Control Center that adapts within established permissions, governance policies, and business objectives. * Expanded agentic workflows help service providers identify growth opportunities, automate marketing campaigns, engage subscribers across more channels, investigate network health alerts, and identify emerging outages. This enables them to grow revenue, strengthen subscriber loyalty, and improve operational efficiency. * Forthcoming Workflow Studio gives service providers a practical path to move from consuming AI to shaping it. The no code-studio will make it easy for service providers to extend automation to their unique business systems, innovate faster, and create differentiated experiences without building and governing an AI ecosystem themselves. Beyond AI-powered workforce and subscriber experiences, Calix is expanding the reach of its operating model into more business and multifamily environments. Expanded SmartMDU(TM) capabilities help service providers win more multifamily properties by delivering experiences that delight both property operators and residents. Building on customer results that include resident satisfaction ratings as high as 95 percent, Calix delivers new activation experiences, a connected vehicle network, and greater deployment control that help providers streamline operations, simplify property management, and deliver exceptional resident experiences at scale. New managed switches further extend the Calix operating model across SmartMDU and SmartBiz(TM) deployments, enabling providers to support more complex environments, including small businesses and large multifamily properties, while managing appliances, switches, and SmartLife through one platform. Michael Weening, president and chief executive officer at Calix, said: "Read the headlines and AI is either the answer to everything or our biggest downfall. The reality is that the opportunity is enormous, but AI has to be trusted, secure, and predictable. That is why we began making significant investments in 2023 to make the Calix One platform AI native. We delivered that foundation in March of this year, building on more than $2 billion invested in our platform over 15 years, 26 years of workflow expertise, and more than 5 billion workflows running annually. Today, our customers are already putting it to work. Now AI is increasing our capacity to deliver more capabilities faster, so our service provider customers can acquire subscribers, grow revenue, reduce costs, and build loyalty. We are proud to be at the forefront of disruption, enabling every customer to transform by increasing their capacity to compete and win." Calix Success(TM) will help service providers translate these innovations into business results through expert guidance, education, launch resources, and proven best practices that accelerate adoption and operational execution.
