The ZTE Wantong ISG IR series is a family of industrial IoT cellular routers that connect remote equipment over public 3G/4G or 5G networks. All six models use an industrial 32-bit communication processor, an industrial wireless module and an embedded real-time OS, in a metal IP30 housing rated -35 to +75°C with DC 5–36 V input. Each has a serial port for transparent data transfer from RS232/RS485 devices, plus Ethernet routing with NAT, firewall, DHCP, DDNS, APN/VPDN and, on the VPN version, PPTP/L2TP/IPsec. Optional dual-link failover backs up a wired WAN with cellular. The IR110 and IR120 pairs are 4G LTE routers with one WAN and four LAN ports; the IR520 and IR530 are compact 5G NR units. All specifications below are quoted from the manufacturer's documents — where a field was not published, we leave it out.

The IR520 (93×89×24 mm, 250 g) is a field data gateway with built-in Modbus, BACnet, DNP3.0, IEC 101/104, DL/T 645 and major PLC protocols, and an optional dual SIM. The IR530 (157×97×25 mm, 440 g) adds a GPS module for positioning and timing.

Is this the right router series for you?

Plain-language guide — based only on what these routers actually do.

Remote CCTV and solar sitesWhere there is no fibre or DSL: a camera, NVR or small PoE switch plugs into the LAN ports and the router carries the video over 4G or 5G. DC 5–36 V input lets it run from a 12 V or 24 V battery bank; the IR110/IR120 draw under 500 mA at 12 V.
Utility, IoT and PLC telemetryMeters, PLCs and RTUs on RS232/RS485 send data transparently to the control centre; the IR120 adds digital inputs and a relay for alarms and remote switching, and the IR520 speaks Modbus RTU/TCP, DNP3.0, IEC 101/104 and DL/T 645 itself.
Kiosks, vending and vehiclesA self-service terminal, vending machine or POS point gets its own cellular link with VPN back to head office; the IR530 adds GPS positioning for vehicles and mobile assets, and the wide DC input covers 12 V and 24 V systems.
Not the right pick if you need…
  • A branch-office router with more wired ports and throughput — that's the ZTE Wantong ISG access routers (ISG 1800-2S / 2800-4 / 3800-8)
  • PoE to power cameras directly — these routers have no PoE; add a small PoE switch such as the ZTE Wantong S1000 SMB series behind the LAN port
  • Next-generation firewall functions such as IPS and antivirus at a site edge — the ZTE Wantong ISG F-series firewalls cover that

Who uses it, where it goes and how to plan a cellular site

Written for the ZTE Wantong ISG IR series from its own specifications: 6 industrial routers, 4G LTE on all and 5G NR on two, a serial port on every model, DC 5–36 V input, -35 to +75°C, metal IP30 housing, no PoE.

Who it is for

  • CCTV installers with remote sites — Farms, construction sites, warehouses, roadside poles and solar-powered camera points with no fixed line: the router carries the NVR or camera streams over 4G/5G, with VPN or DDNS for remote viewing.
  • Utility and IoT integrators — Smart grid, water, environmental and weather monitoring: RS232/RS485 meters and RTUs, IR120 digital inputs and relay, and the IR520's built-in Modbus, DNP3.0, IEC 101/104 and DL/T 645 protocols.
  • Kiosk, vending and POS operators — Self-service terminals, vending machines, kiosks and mobile POS points that need their own link with VPN back to head office, independent of the shop's network.
  • Fleet, oil & gas and agriculture projects — Vehicles and mobile assets that need position and data (IR530 GPS), wellheads and pipeline stations on DC power, and irrigation or greenhouse controllers reached over the serial port.

Where and how to install

  • Inside a cabinet, not in the open — The housing is metal but rated IP30, so outdoors it must go inside a weatherproof enclosure or pole box. Operating range is -35 to +75°C with 95% non-condensing humidity; shade the enclosure in strong sun and avoid condensation.
  • Mounting — The IR520 and IR530 are listed for DIN-rail or wall mounting. The IR110 (206×135×28 mm, 790 g) and IR120 (134.8×115.7×45 mm, 520 g) mounting method is not stated in the documents; confirm the bracket with us for your cabinet.
  • Power wiring — All models accept DC 5–36 V (standard adapter 12 V/1.5 A), so they can run from a 12 V or 24 V battery or solar controller output. Connectors differ: 3-pin locking DC socket on the IR110 and IR530, 2-pin terminal on the IR120, 3.5 mm terminal on the IR520. Observe polarity even though reverse protection is built in.
  • Antennas and signal — Cellular antennas connect on SMA female (2 on the IR110/IR120, 1 listed on the IR520), Wi-Fi on SMA male and GPS on SMA (male on the IR120, female on the IR530). In a metal cabinet, bring the antennas outside on a short low-loss cable and point them toward the tower; antenna lightning protection is an option.
  • Serial and I/O wiring — Match the serial mode (RS232 or RS485/RS422) and the data bits, parity, stop bits and baud rate (2400–115200 bit/s) of the field device. On the IR120 I/O terminal, digital inputs read high at 5–30 VDC and low at 0–3 VDC; switch larger loads through the relay (1 A 250 VAC/30 VDC), not the output (<50 mA @ 30 VDC).

ISG IR series planning: which of the 6 models

All six are industrial cellular routers with a serial port, NAT/firewall routing, optional VPN version, DC 5–36 V input and no PoE; they differ in cellular generation, wired ports, Wi-Fi, I/O and GPS. Power at 12 V is arithmetic from the published working current (W = A × 12 V).

  • Pick the IR111 or IR112 for a remote CCTV point with an NVR or a small PoE switch on the LAN side; four 10/100M LAN ports are plenty when the cellular uplink (50 Mbps theoretical) is the real limit.
  • Pick the IR121 or IR122 when the site also needs a door contact, alarm input or a relay to reset equipment, or when a local gigabit LAN matters.
  • Pick the IR520 for small solar or battery telemetry boxes: about 2.0–2.6 W at 12 V (165–220 mA), which is roughly 48–63 Wh per day running 24 hours.

— = not listed / not applicable. Rates are the theoretical maximums in the documents (IR520 also lists LTE Cat-12/Cat-6/Cat-4 figures). Power is arithmetic: <500 mA × 12 V = <6 W; 165–220 mA × 12 V = 1.98–2.64 W; the IR530 current is not published. Daily energy = W × 24 h, before battery and controller losses.

Engineer's note: Cellular bands, module version (standard, all-network or VPN), Wi-Fi and antennas differ across the six models. Tell us the country, carrier and site, and we will put together the configuration list free of charge: model and module version, SIM and APN settings, cellular/Wi-Fi/GPS antennas and cable lengths, power wiring (adapter or DC battery feed) and the PoE switch for the cameras. We can pre-configure APN, VPN, DDNS and port mapping before delivery.

Industrial Cellular Router FAQ — ISG IR Series

Which ISG IR model should I choose?
For a 4G site with several wired devices, take the IR110 pair (1 WAN + 4 LAN at 10/100M) or, for gigabit ports plus 2 digital inputs, 1 output and 1 relay, the IR120 pair; pick the IR112 or IR122 if you also need Wi-Fi. For 5G in a small box with one LAN port, take the IR520 (250 g, industrial PLC protocols, optional dual SIM) or the IR530 when you need GPS positioning. All six share the serial port, DC 5–36 V input and -35 to +75°C rating.
Which cellular bands do these routers support, and will they work with my carrier?
As published: the IR111/IR112 list LTE FDD Band 2/4/5/13/17/25 plus CDMA 800/1900 MHz; the IR121/IR122 and IR520 list FDD LTE Band 1/3 with Band 2/4/5/13/17/25 optional; the IR520 and IR530 add 5G NR n1/n3/n8/n28/n41/n77/n78/n79, and the IR530 lists LTE FDD 2600/2100/1800/900/800 MHz plus 3G and GSM bands. An all-network module is optional on the IR110, IR120 and IR520. Please confirm your carrier's bands with us before ordering: we offer a free remote check — take an Android phone with the local SIM to the installation site and WhatsApp-video-call us, and we guide you to read the bands actually in use there.
Do I need the 5G models, and will I really get 3.4 Gbps?
3.4 Gbps down / 350 Mbps up is the theoretical 5G NR figure for the IR520 and IR530; real speed depends on coverage and the carrier. Their wired WAN and LAN ports are 10/100M, so a single wired device behind them is limited to 100 Mbps. For CCTV the uplink matters most: 5G lists 350 Mbps up against 50 Mbps for LTE on the IR110/IR120, so 5G helps where many cameras upload at once and 5G coverage exists; for a few cameras 4G is usually enough.
Can the router back up a wired internet line, and how do I get VPN?
Yes, dual-link intelligent failover between the wired WAN and the cellular link is listed as an option on all six models; the wired WAN accepts static IP, DHCP or PPPoE, including direct connection to an ADSL modem. PPTP, L2TP and IPsec VPN client and server functions are available on the VPN version only, so tell us if you need VPN and we will supply that version. APN/VPDN is supported for carrier private networks.
Can these routers read meters and PLCs or switch equipment remotely?
Every model has one RS232 port (RS422/RS485 on most, RS485 on the IR520) at 2400–115200 bit/s for transparent transfer to your server. The IR121/IR122 add 2 digital inputs (high 5–30 VDC), 1 output and a relay rated 1 A 250 VAC/30 VDC, controlled over Modbus, for alarms or remote switching. The IR520 goes further as a data gateway: it parses Modbus RTU/TCP, BACnet, DNP3.0, IEC 101/104, DL/T 645 and major PLC protocols locally and pushes the data to cloud or IoT platforms.
Can I order under my own company name and use my own forwarder?
Yes to both. Corporate buyers can have the purchase order submitted to the manufacturer under their own company name, so your company appears on the official order. For small and mid-size orders we also deliver directly to your designated forwarder's warehouse in China on EXW or FOB terms.
How many cameras can I view through one IR router?
The limit is the cellular uplink, not the LAN ports. As arithmetic: if each camera's remote-view substream is 512 kbps, 8 cameras need about 4 Mbps of upload, which a working 4G link usually carries; full-resolution main streams at 2–4 Mbps each add up quickly. Record locally on an NVR at the site and pull only substreams or clips over the cellular link, and check the real upload speed at the site before deciding.
Can I reach the NVR from outside if the SIM has no public IP?
Port mapping (DMZ/NAT) and DDNS only work from outside when the carrier gives the SIM a public IP address. Many mobile carriers use private addresses, so the usual approach is the VPN version of the router acting as a VPN client (PPTP, L2TP or IPsec) toward a VPN server at your office or in the cloud, or a carrier private APN/VPDN. A camera vendor's P2P cloud service also works without a public IP; tell us which method you plan and we will pre-configure it.
Can an IR router run from a solar panel and battery?
Yes, the DC 5–36 V input covers 12 V and 24 V battery systems directly. As arithmetic: the IR110/IR120 draw under 500 mA at 12 V, so under 6 W or about 144 Wh per day; the IR520 draws 165–220 mA, about 2.0–2.6 W or 48–63 Wh per day. Add the cameras and switch to size the panel and battery, and allow for cloudy days. The IR110, IR120 and IR530 also list sleep and scheduled on/off modes on special versions, which can cut consumption further.
What does the IR530 GPS give me for vehicles and mobile assets?
The IR530 has a 50-channel GPS L1 receiver with SBAS (WAAS/EGNOS/MSAS/GAGAN), up to 4 Hz updates, 2.5 m CEP accuracy (2.0 m with SBAS), hot start under 1 s and a configurable time pulse with 30 ns RMS timing accuracy. It needs its own GPS antenna on the SMA female connector with a view of the sky. The documents do not describe which tracking platform or report format the position is sent to, so tell us your fleet platform and we will confirm compatibility before ordering.
Can I install the router in an outdoor pole box with the cameras?
Yes, that is a common position, as long as the box itself is weatherproof: the router is rated IP30, so it must not be exposed to rain or dust directly. It is rated -35 to +75°C, which covers a shaded pole box in most climates. Keep the cellular antenna outside the metal box, use the optional antenna lightning protection on tall poles, and bond the box to earth.
Can I order one unit first, and how does it reach my country?
Yes — a single sample can be ordered and sent by air. For larger orders we deliver EXW or FOB to your freight forwarder's warehouse in China, or arrange air or sea freight to your country on request. Every shipment comes with a commercial invoice and packing list for customs; import duties and VAT in your country are not included unless agreed in writing.
How do I pay?
By bank transfer (T/T) in US dollars against our proforma invoice, which lists the model, quantity, unit price, delivery terms and lead time. You can check our company details on the verification page before you pay.
