G.hn Wave2 · up to 2 Gb/s PHY

Gigabit broadband over the wire that's already there.

NextAccess designs carrier-grade G.hn access equipment that turns existing coax and telephone copper into fibre-class connections — no riser works, no rewiring, no tenants displaced.

// Product families

One platform. Every legacy medium.

Headends sit in the comms room on your fibre. Network terminations plug into the wall socket already in the apartment. Everything is managed as one system.

// Architecture

Fibre to the building. G.hn the rest of the way.

A fibre-to-the-distribution-point design: bring fibre to the comms room, and let NextAccess handle the last few hundred metres on the cable already running to every unit.

// Under the hood

Carrier features, not consumer powerline.

Every NextAccess headend is a fully managed Layer 2 access switch with G.hn ports — built for ISPs who need to operate thousands of subscribers, not plug in a pair of adapters.

OFDM, 2–200 MHz

G.hn Wave2 baseband with dynamic PSD, power-mask notching and radio-band notching so it plays nicely with broadcast and amateur RF.

Per-subscriber QoS

8 queues per port, SPQ/WRR scheduling, 802.1p and DSCP marking, ingress/egress rate limits and 128 ingress ACLs for individual SLAs.

4K VLANs, 16K MACs

802.1Q, Q-in-Q friendly classification, 802.3ad LACP (8×8), RSTP/MSTP and 9K jumbo frames on the uplink.

IPTV ready

IGMP snooping v1/v2, up to 512 multicast groups and multicast filtering — multi-stream 4K IPTV without flooding the line.

Subscriber security

DHCP Option 82 (circuit-ID per port), DHCP snooping rate-limits, MAC-count limits, broadcast storm control and port isolation.

Zero-touch CPE

NTUs are discovered, configured and firmware-upgraded from the headend. No technician visit to change a plan.

// VectorBoost

Elastic capacity for dense copper bundles.

Telephone cable binders crosstalk. VectorBoost applies Dynamic Spectrum Management across every pair on a headend, shifting capacity to the line that needs it — in real time.

  • No action at idle. Lines run the default ITU-T G.hn profile while demand is below channel capacity.
  • Millisecond reconfiguration. PSD level, frequency band and time-on-wire adjust when a line bursts.
  • Burst to near-gigabit. A single busy subscriber borrows headroom from quiet neighbours.

// Solutions

Built for buildings fibre forgot.

01 / MDU

Apartments & strata

Retrofit gigabit into existing towers via the TV riser. Activate units on move-in without body-corp works approvals.

02 / HOSPITALITY

Hotels & student living

Every room already has a coax outlet. Add a 4-port NTU and a managed VLAN per room for TVs, phones and the room router.

03 / HERITAGE

Heritage & brownfield

Where drilling walls isn't allowed, G.hn over phone pairs delivers fibre-class speeds through cabling installed decades ago.

04 / COMMERCIAL

Offices & mixed-use

Light up tenancies over the copper already in the riser — gigabit per suite without new cable runs or ceiling works.

// NextView NMS

Operate a building like a single switch.

NextView gives your NOC topology, per-subscriber line stats, bulk firmware and alarms across every headend and NTU — alongside the open interfaces your OSS already speaks.

  • SNMP v1/v2c/v3, traps, RMON and Syslog into your existing monitoring.
  • Web GUI, CLI, Telnet and serial console with three admin privilege levels.
  • Remote firmware for headend and CPE; config backup/restore via TFTP.
  • SFP DDMI optical diagnostics on every uplink.
