Rethinking non‑access stratum timers for LEO satellite constellations in 5G and beyond
Guest Post: AstroTimer starts from a simple but important question: Can we compute NAS timers directly from LEO‑specific conditions, such as path length, link variability, and NF load, using a closed‑form, low‑cost model?
The economics of SpaceX
SpaceX and Starlink’s valuation, reality, and the limits of connectivity economics.
Mobile Internet prices in PNG: Stability amid infrastructure developments
Guest Post: Mobile Internet prices in PNG remained largely stable in 2025, with some unpredictable fluctuations. As new undersea cables and satellite services emerge, the market may be entering a new phase of competition and change.
The invisible hand: Regaining control of service quality from outsourced satellite networks
Guest Post: MNOs lease LEO satellites from SNOs as a cost-effective way for to expand coverage, but cannot guarantee service quality without control over the satellites. Ripple is a competition-driven framework that directly links SNOs’ revenue to the service quality they deliver.
Direct‑to‑device and the return of LEO ambitions
LEO satellite networks are returning to the mobile market, this time shaped by lower launch costs and changing industry economics, with lessons from Iridium still looming.
CDNs, optical communications, and AI at NZNOG 2026
Geoff Huston attended NZNOG 2026, and shares some of what he found interesting.
Thousands of LEO satellites won’t save us (but good regulation will)
Guest Post: This post explores how different economies approach LEO satellite regulation, why these choices matter, and what a balanced, future-proof framework should look like.
Secure and scalable rerouting in LEO satellite networks
Guest Post: How does the scope of failure awareness affect routing performance and resilience in Low Earth Orbit satellite constellations?
Three of the best: Measurement
Measurement is always a popular topic on the APNIC Blog. This year, authors measured everything from Distributed Denial of Service (DDoS) prevention to Internet Service Provider (ISP) market share. Here are three of the best.
