FRITZ!Box 6860 5G — Weatherproof 5G Router with Wi-Fi 6 for Window or Outdoor Mounting
5G SA/NSA + 4GIP54 housingWi-Fi 6 up to 3 Gbit/sPoE+ single cable
The FRITZ!Box 6860 5G is a compact 5G router in an IP54 housing that can be mounted indoors, at a window or in protected outdoor areas where the mobile signal is strongest, for homes, holiday properties and small businesses that rely on mobile broadband. It reaches up to 1.3 Gbit/s download over 5G with four internal antennas in 4x4 MIMO, and shares the connection over Wi-Fi 6 at up to 3 Gbit/s with FRITZ! Mesh.
A single PoE+ cable carries both power and data from the supplied PoE+ adapter, which provides one Gigabit LAN port indoors. It also acts as a DECT base for six handsets and DECT ULE smart-home devices, with VoLTE/VoNR, IP telephony, five answering machines and fax.
Before you order: It takes a nano-SIM. The PoE+ adapter has one Gigabit LAN port; for more wired devices add a switch. FRITZ! does not publish the plug type for this item number — ask us before ordering.

What It Means in Practice
- Mount it on a window or a sheltered outside wall facing the mast and run one slim cable indoors — signal improves without extra antennas.
- Wi-Fi 6 up to 2400 Mbit/s on 5 GHz covers the area around the unit; add FRITZ! Mesh repeaters indoors for full coverage.
- Plug a switch into the PoE+ adapter's LAN port to wire several devices.
- Operating range -10 to 40 °C suits sheltered outdoor locations in most climates.
What Will Not Work
- It is rated for protected outdoor areas, not exposed rooftops with direct rain and full sun all year.
- It does not take a mini-SIM directly — nano-SIM only.
- There is only one wired LAN port (on the PoE+ adapter), no USB port is listed, and no analogue phone port.
- It has no DSL or cable modem.

Singular Expert Insight · Buyer's Guide
The 6860 5G solves the classic mobile-broadband problem — the best signal is outside, the devices are inside — with one PoE+ cable and a weatherproof case. For indoor coverage, add repeaters from our
range boosters section.
✓ Buy it if reception indoors is weak and you can mount the router at a window or sheltered outside wall.
✕ Skip it if you need several LAN ports, USB or an analogue phone port on the router itself — the 6850 5G has them.
→ Also consider the FRITZ!Box 6850 5G for a classic indoor desktop router with 4 LAN ports.
Tell us your location, operator and where you want to mount it, and we will check signal and cabling before you order.
