Die weißen Flecken auf der Landkarte
Zu Beginn des Powerline-Rollouts liegt das eigene Netzgebiet als eine unerschlossene Landkarte voller weißer Flecken vor. Bisherige PLC-Systeme mussten an diesem Punkt bereits unterschiedliche Extremanforderungen stemmen und zusammenführen – meist mit nur wenig Erfolg. Schmalbandsysteme mit wenigen kHz Bandbreite waren gut geeignet darin, den Weg aus dem Zählerschrank im Keller bis zur Ortsnetzstation zu überwinden – die Datenübertragungsrate ist allerdings sehr gering und moderne TLS-Verschlüsselung so unmöglich.
Der entgegengesetzte Ansatz, sich im „Gigabit PLC“ zu bewegen, wirkt auf den ersten Blick interessant, stellt Netzbetreiber im Feld allerdings ebenso schnell vor Probleme. Denn die Übertragung solcher Datenmengen benötigt einen enormen Frequenzbereich, oft bis 50 MHz, auf geschirmten Kabeln mitunter bis 100 MHz. Die Schwierigkeit dabei? Höhere Frequenzbereiche werden im praktischen Umfeld des Tiefpassfilters „Kabel“ als erstes ausgedämpft – und damit ist am Ende oft gar keine Verbindung zwischen zwei Kabelverteilern möglich. Es erreichen schlicht nicht genug Subcarrier den gewünschten Empfänger.
Ein erfolgreicher, schneller und kosteneffizienter BPL-Ausbau muss sich beiden Herausforderungen stellen können – schnellstmöglich auch größere Entfernungen in der Anbindung überbrücken zu können und trotzdem Datenraten im MBit/s-Bereich für moderne Verschlüsselung ermöglichen.
PPC’s BPL Generation 6 (Nessum): Bandpläne, so flexibel wie es der Rollout benötigt
Genau hier spielt die Nessum Technologie ihre Stärke aus – und hebt Breitband-Powerline-Netzen (BPL) auf eine ganz neue Stufe an Flexibilität.
Der entscheidende Vorteil: Netzbetreiber müssen sich nicht mehr zu Beginn des Projekts fest auf einen Frequenzbereich festlegen. Stattdessen ermöglicht Nessum den dynamischen Wechsel zwischen Long-Range- und High-Speed-Bandplänen – je nach Phase des Netzaufbaus. Das Umschalten erfolgt dabei komfortabel aus dem PPC Netzwerkmanagement-System (NMS), ohne neue Anfahrten oder manuelles Nachfassen.
Für Netzbetreiber bedeutet das: Kein Risiko durch frühzeitiges Festlegen, weniger Aufwand im Rollout und maximale Zukunftssicherheit. Mit PPC’s BPL-Geräten der 6. Generation, lässt sich so zunächst ein robustes Netz errichten, bei dem die schnelle Anbindung im Vordergrund bleibt. Steht die BPL Infrastrukur erstmal, kann per Knopfdruck auf hohe Datenrate umgestellt werden – denn jedes eingebaute BPL-SMGW funktioniert gleichzeitig als vollautomatischer Repeater.
Somit gewährleistet Nessum stets genau die Flexibilität, die moderne Energienetze brauchen. Ob heute oder in der Zukunft.

The blank spots on the map
At the start of the powerline rollout, your own network area is like an unexplored map full of blank spots. Previous PLC systems had to cope with and combine different extreme requirements at this point – usually with little success. Narrowband systems with a bandwidth of a few kHz were well suited to covering the distance from the meter cabinet in the basement to the local network station – however, the data transfer rate is very low, making modern TLS encryption impossible.
The opposite approach, moving to ‘gigabit PLC’, seems interesting at first glance, but quickly presents network operators in the field with problems. This is because the transmission of such large amounts of data requires an enormous frequency range, often up to 50 MHz, on shielded cables, sometimes up to 100 MHz. The difficulty here? Higher frequency ranges are the first to be attenuated in the practical environment of the low-pass filter ‘cable’ – and this often means that no connection between two cable distributors is possible in the end. Simply not enough subcarriers reach the desired recipient.
A successful, fast and cost-efficient BPL expansion must be able to meet both challenges – bridging even greater distances in the connection as quickly as possible while still enabling data rates in the Mbit/s range for modern encryption.
PPC’s BPL Generation 6 (Nessum): Band plans as flexible as the rollout requires
This is precisely where Nessum technology comes into its own – taking broadband powerline networks (BPL) to a whole new level of flexibility.
The decisive advantage: network operators no longer have to commit to a specific frequency range at the start of the project. Instead, Nessum enables dynamic switching between long-range and high-speed band plans – depending on the phase of network construction. Switching is conveniently carried out from the PPC Network Management System (NMS), without the need for new trips or manual follow-up.
For network operators, this means no risk from early commitments, less effort in rollout and maximum future security. With PPC’s 6th generation BPL devices, a robust network can be established initially, with the focus on fast connectivity. Once the BPL infrastructure is in place, you can switch to high data rates at the touch of a button – because every built-in BPL-SMGW also functions as a fully automatic repeater.
Nessum thus always guarantees exactly the flexibility that modern energy networks need. Whether today or in the future.
