Secure home internet connectivity is now critical for a growing share of households. According to a survey by Calix Market Insights, 37 percent of subscribers use their residential internet service for work, and more than 1 in 3 subscribers who have switched providers chose security services. This reinforces the expectation that connectivity must be secure to protect sensitive applications and critical workflows. For service providers, these needs represent an opportunity to drive average revenue per user (ARPU), as 35 percent of subscribers surveyed report receiving partial or full reimbursement for internet service from their employer.

New HomeOfficeIQ capabilities and enhancements for SmartHome enable providers to deliver:

-- Safe, secure connections during unavoidable network outages. HomeOfficeIQ quickly restores connectivity to critical and prioritized devices during outages, while keeping ProtectIQ active and applying the content controls of ExperienceIQ. Together, these ensure a safe, secure experience-helping safeguard video meetings, cloud-based applications, and other time-sensitive activities. HomeOfficeIQ is fully compatible with the award-winning Calix GigaSpire(R) portfolio.

-- Personalized network controls over SSIDs or IoT devices for subscribers. When a cellular hotspot is activated leveraging HomeOfficeIQ, households can easily select and prioritize either multiple SSIDs or multiple devices. This helps ensure essential activities like work, school, or telehealth stay connected-giving households meaningful control over their network for the moments that matter most.

-- Built-in CommandIQ promotions that boost engagement and drive adoption. Integrated directly into CommandIQ, promo and announcement tiles help providers promote new offers, share service updates, and educate users, increasing engagement and accelerating SmartHome adoption. CommandIQ recently earned the TMC 2025 Cybersecurity Excellence Award for advanced subscriber protection.
