The InHand Networks IR315-FF39-G is the North American LTE Cat 6 build of the IR315 industrial router. It adds GNSS positioning and 4 configurable digital I/O channels to a DIN-rail, fanless metal unit. It has five 10/100 Ethernet ports, dual Nano-SIM failover, 9-36 VDC input and a -35 °C to 70 °C standard operating range, which suits unattended IoT and remote sites managed from InHand Device Manager.
The IR315-FF39-G is an industrial cellular router for sites that need reliable connectivity without a technician on hand. Typical sites include cabinets, kiosks, pump stations, substations and vehicles. This part number is the North American (FF39) LTE Cat 6 model, with LTE Band 66 and Band 71 support. It pairs GNSS with the IR315's default I/O block of 4 digital channels, each configurable as input or output.
Five 10/100 Mbps RJ45 ports can each act as WAN, LAN or VLAN, and each port has 1.5 kV isolation protection. A drawer-type slot holds two Nano-SIMs. The router can switch SIMs based on signal threshold, packet loss or dial failures. Cellular and wired WAN can back each other up in hot backup, cold backup or load-balancing mode, and VRRP and an embedded watchdog add further redundancy. The GNSS receiver supports GPS, GLONASS, BeiDou, Galileo and QZSS with ±2.5 m accuracy, and it can also serve as a time source for the router's NTP server.
Security is built into the firmware. It includes an SPI firewall, DoS protection, ACLs, 802.1x and IP-MAC binding. VPN options are IPsec (up to 10 tunnels, AES256-SHA512), OpenVPN, WireGuard, ZeroTier, L2TP, GRE, DMVPN and PPTP. Firmware images carry signature verification. For fleet work, the router connects to InHand Device Manager for batch configuration and remote firmware upgrades, and it also supports SNMP v1/v2c/v3, an HTTP/HTTPS API, SSH and SMS status queries.
The enclosure is IP30-rated metal with fanless cooling, measuring 127 × 108.2 × 35 mm and weighing 454 g. It accepts 9-36 VDC through a 2-pin industrial terminal with overcurrent and reverse-polarity protection. The IR315 Datasheet V1.3 and a DIN-rail 2D drawing are available for this model.
FF39 is the North American LTE Cat 6 radio. The -G suffix adds GNSS, and because there is no -S suffix, the unit has the default 4 × configurable digital I/O rather than serial ports. There is no -WLAN suffix, so Wi-Fi is not fitted.
The IR315 GNSS option supports GPS, GLONASS, BeiDou, Galileo and QZSS with ±2.5 m accuracy. It can also provide GPS time synchronization for the router's NTP server.
Install the antennas, insert the SIM with the router powered off, then connect power. Connect a computer to a LAN port, set it to DHCP or a 192.168.2.x static address, and browse to http://192.168.2.1. Log in with the credentials printed on the device label.
Usually not. The IR315 auto-detects the carrier and applies the matching APN in most cases, including built-in profiles for AT&T, Verizon and T-Mobile. If the link does not come up, set the APN under Network > Cellular.
Yes. Under Network > Link Backup, set WAN as the main link and cellular as the backup, then choose hot backup or cold backup and set an ICMP detection server. Load balancing across links is also supported.
