Summary
2. DOCSIS 4.0 brings more capacity
1. Coax is a powerful asset
3. 1.8 GHz amplifiers are ready just around the corner
• But when do upgrades make sense?
• Cable lengths, drop cable losses, legacy systems,
in-house networks, etc.
4. In practice
• Trials can start in 2021
• 1.8 GHz amplifiers are waiting DOCSIS 4.0 devices,
not vice versa
5. In coax we trust!
