rCell 100 Series notes

My working notes on the MultiTech MultiConnect rCell 100 — an industrial LTE cellular router I run as a backup uplink and for a couple of remote sites. Setup steps, LED meanings, config snippets and the things that bit me.

The MultiConnect rCell 100, in plain terms

What it is

The MultiConnect rCell 100 Series is a compact, DIN-rail mountable industrial cellular router. In practice it's a small ruggedised box that takes a SIM card, connects to an LTE network, and hands that connection to your wired LAN over a single Ethernet port. It's aimed at machine-to-machine / IoT deployments — remote pumping stations, digital signage, ATMs, backup WAN for a small site — anywhere you need an IP path but can't (or don't want to) run fixed-line.

Compared to a consumer 4G router, the things you actually pay for are the wide DC input range, the −30 to +70 °C operating range, the dual SIM for carrier failover, and a management UI that's built for set-and-forget remote operation rather than a phone app. It's not fast — the units I run are LTE Cat 1 / Cat 4 — but it is dependable, which is the whole point.

My one-line summary: it's a boring, reliable industrial LTE gateway. Boring is a compliment here.

Key specs at a glance

These are the figures I care about day to day. They line up with the 100-series units I've deployed; your radio variant and region SKU will differ, especially on bands.

ItemValue (typical, my units)
CellularLTE Cat 1 / Cat 4, with 3G (HSPA+) and 2G fallback on some SKUs
Peak throughputCat 4: up to ~150 Mbps down / 50 Mbps up (Cat 1: ~10 / 5 Mbps)
LTE bands (NA SKU)B2, B4, B5, B12, B13, B14, B66, B71 (varies by region variant)
SIMDual SIM, 2FF, software-selectable, carrier failover
Antennas2 × SMA (Main + Aux / RX-diversity)
Ethernet1 × 10/100 RJ45 (LAN)
SerialRS-232 (DB9) console / passthrough
Input power9–32 V DC (terminal block), ~4 W idle / ~8 W peak TX
Operating temp−30 °C to +70 °C
MountingDIN-rail clip or panel/wall bracket
ManagementLocal web UI (HTTPS), SSH/CLI, SNMP, RS-232 console
Default LAN address192.168.2.1 (DHCP server on by default)

Numbers above are for orientation only, gathered from my own devices — they are not a substitute for the manufacturer's datasheet.

Where I use it

Two roles in my setup. First, as an automatic failover WAN at home: when the fibre drops, the rCell brings up LTE and the firewall reroutes egress to it until the primary comes back. Second, as the only uplink at a small remote cabinet that has power but no wired internet — a handful of IoT sensors and a little NVR sit behind it on a cheap unmanaged switch.

Topology: Internet to cell tower to rCell modem to LAN switch to devices
Typical placement: the rCell is the edge device between the carrier's LTE network and a wired LAN segment.
