Setup of iFemtoCell-evolution Hotspot

Ethernet* The maximum Ethernet cable length is 100m

Install the Hotspot

For best mining performance, place the hotspot on the roof or high up. It is very important to maintain the antenna vertically and without any obstacle at 20 cm around.
Avoid placing the hotspot in places where it cannot see the outside world: in basements, in cabinets, behind TVs, metal screens.
You can manage, plan and optimize your hotspot locations using Hotspotty


The Wirnet iFemtoCell-evolution may be mounted on a wall using the two oblong holes.
Only two screws (not included) are needed, all mounting information is mentioned on the following drawing: /!\ Never use hooks!


Once the Wirnet iFemtoCell-evolution is installed, you can select up to 2 technologies to access to Internet for the data backhaul:

Note that both configurations can be used in parallel. For example, RJ45 Ethernet with a 4G/3G link as a backup.


Once the LoRa RF antenna, the Ethernet cable (if used) or the 4G/3G (with USIM card inserted) and the power supply jack connector are plugged, the Wirnet iFemtoCellevolution can be powered ON by connecting the power supply.

Power On the Hotspot & LED status

Once the LoRa RF antenna, the Ethernet cable (if used) or the 4G/3G (with USIM card inserted) and the power supply jack connector are plugged, the Wirnet iFemtoCellevolution can be powered ON by connecting the power supply.
The button available on the right of the hotspot and accessible thanks to a tool with a 1mm diameter allows to reset the hotspot as follow:

Connection to the Hotspot

Connect to Web interface

DO NOT CLICK on RESET FACTORY button as it will remove the Helium miner software from your Hotspot.
The feature is reserved to technical Support Team

The easiest way to connect to your hotspot is to address it by name.

Using local connection through USB-C.

Network setup

The network can be easily configured thanks to the web interface.

Ethernet (default)

Cellular

The Full Miner communicates over a peer-to-peer (P2P) network and needs to connect to the remote port 44158.
The Light Hotspot → Validator connection is a standard gRPC connection. The default port Validators listen on is 8080 so Hotspots should be able to connect Outbound to that port.
Hence, other miners must have this port forwarded to their miner IP address, and so should you. Indeed, other miners will want to connect to your miner too.
More info on port forwarding can be found on Helium documentation:

Do not expose/port forward the TCP port 80 from the outside.

Firmware and Miner updates

Firmware and miner updates are managed by KERLINK.

Factory reset

It will delete Helium on your Hotspot. DO NOT USE except if your reseller asked you to factory reset your Hotspot!

LoRaWAN protocol

Kerlink is a member of LoRa Alliance and the Kerlink hotspot is compatible with LoRaWAN protocol. If you need information about LoRaWAN network protocol please contact the LoRa Alliance and request LoRaWAN specification : https://lora-alliance.org/lorawan-for-developers
