CableLabs Spec Enable Advanced IP Service

CableLabs issued a series of new PacketCable specifications covering areas such as existing standards-based SIP (Session Initiation Protocol), security, quality of service, network address translation (NAT) & firewall traversal, and device provisioning. The specifications will enable cable operators to deliver IP-based communication and entertainment services to customers' televisions, personal computers, and fixed-line and mobile phones.

The specifications were developed in alignment with the Internet Protocol Multimedia Subsystem (IMS) architecture developed by the 3GPP - 3rd Generation Partnership Project, a collaboration of a number of key telecommunications standards bodies. Using widely accepted standards-based protocols such as the Internet Engineering Task Force's (IETF) SIP, these specifications will offer operators a flexible way to deploy network capabilities as required by their specific service offerings, while maintaining interoperability across a variety of devices from multiple suppliers.

These documents extend the industry's PacketCable architecture, originally defined in 1999 and now widely deployed over cable broadband networks. According to recently published market data, nearly 3 million cable customers receive digital voice service from PacketCable-based networks with that number expected to grow to 6.5 million by year-end.

Global Satellite Broadband Revenue Forecast

The satellite communications industry is experiencing a transformative moment. What was once the exclusive domain of government agencies and deep-pocketed corporations is rapidly becoming accessible to everyone. This democratization of space-based connectivity represents a significant technological achievement and a fundamental shift in our understanding of global communications infrastructure. The dramatic acceleration in satellite system deployment tells a compelling story. Satellite Broadband Market Development With over 160 launches recorded by August 2025 alone, we're witnessing an unprecedented build-out of orbital infrastructure. This surge is driven by three converging factors:  Plummeting launch costs through reusable rocket technology, the miniaturization of satellites enabling bulk launches, and intensifying commercial competition among private companies and nations alike. The result is a space ecosystem that looks radically different from even a decade ago, with approxi...
