Kerlink Wirnet™ iFemtoCell-evolution | Indoor LoRaWAN Gateway with Cellular Communication

The Kerlink Wirnet iFemtoCell-evolution is an elite indoor LoRaWAN® gateway with internal 3G/4G cellular plus Ethernet backhaul, engineered for smart cities, smart buildings, and large-scale metering. It delivers superior coverage in the most demanding environments — basements, underground car parks, elevator shafts — making it ideal for connecting energy meters, parking sensors, and equipment actuators.

Built on the proven Wirnet i-Series platform with built-in high-rejection filters and a hardware-secured Trustzone architecture, it pairs reliable RF performance with operational excellence. Zero-touch provisioning, an embedded ChirpStack server, and the Kerlink Wanesy™ Management Center make it quick to deploy and easy to operate at scale.

Core Capabilities

Superior LoRa Radio Built on Semtech Reference Design v1.5, with 8-channel RX (125 kHz, multi-SF) plus 250/500 kHz, FSK, and TX channels — 10 RX + 1 TX. Rx sensitivity down to −140 dBm (SF12), Tx 5–24 dBm, 27 dBm EIRP, with built-in high-rejection filters and LBT. Internal 4G + Ethernet Backhaul A worldwide 4G module with 3G/2G fallback (mini-SIM) and 10/100 Ethernet (RJ45), with an integrated LTE antenna. The Ethernet/Wi-Fi/4G variant (IFE07) adds Wi-Fi backhaul. Hardware-Grade Security A Trustzone-based secure core with SecureBoot (signed firmware), SecureStorage via ProvenCore™, and OpenVPN/IPsec backhaul protection, plus watchdog recovery to a known-good configuration. Easy to Deploy & Manage Zero-touch provisioning and maintenance (ZTP/ZTM), an embedded ChirpStack network server, and the Wanesy™ Management Center with Web GUI. Powered from AC/DC or 5 V USB-C, with optional UPS autonomy.

Typical Applications

• Smart Buildings & Facilities: Deep-indoor coverage for basements, car parks, and elevator shafts — connecting meters, sensors, and actuators. • Smart Energy & Metering: Reliably back-haul energy, water, and sub-metering data over cellular or Ethernet. • Smart Cities & Public Operators: Densify public or private networks indoors where outdoor gateways can't reach. • Smart Agriculture & Industry: Indoor connectivity for farm buildings, warehouses, and industrial facilities.

Choosing Your Variant

Model	Backhaul	Best For
PDTIOT-IFE03 (EU868)	Ethernet + 4G	Most indoor sites — wired plus cellular backhaul.
PDTIOT-IFE07 (EU868)	Ethernet + Wi-Fi + 4G	Sites that also need Wi-Fi backhaul flexibility.

Both variants are EU868 (covering EU863-870, IN865-867, RU864-870). All units include the internal 3G/4G module with 2G fallback.

Frequently Asked Questions

How is it powered?

By the included AC/DC supply (90–264 VAC / 12 VDC, 5.5×2.5 mm jack) or 5 V DC via USB-C. Optional UPS accessories provide 5 h or 24 h of backup autonomy.

What's the difference between IFE03 and IFE07?

Both have internal 4G (3G/2G fallback) plus Ethernet. The IFE07 additionally offers Wi-Fi backhaul for extra flexibility.

Can it run a network server on-device?

Yes. It includes an embedded ChirpStack LNS and is compatible with the Wanesy Small Private Network solution for standalone, self-operating LoRaWAN networks.

Is it suitable for deep-indoor sites?

Yes — it's designed for demanding indoor environments like basements, car parks, and elevator shafts, with internal cellular backhaul where wired internet isn't available.

Which band does this model use?

This is the EU868 model, covering the EU863-870, IN865-867, and RU864-870 LoRaWAN regional parameters.
