What type of antenna and connectors?

To get the best possible performance depending on the location of your Helium miner installation, it is recommended to use an antenna installed outside, as high and clear as possible on 360°.

The use of an antenna, correctly tuned to the frequency band used by the Helium network is also recommended, such as the 868 MHz tuned antenna OPA Design. This antenna is with a female N connector.

The Rock Pi hotspot is equipped with an RP-SMA female connector, not to be confused with an SMA connector. A male RP-SMA connector must be chosen to be compatible with this helium hotspot.

To connect the recommended antenna directly to the miner, the cable must have an RP-SMA male connector on one side (to go to the HS) and an N male connector on the other (to go to the antenna).

We recommend using a low-loss KSR400 (LMR400 equivalent) coaxial cable, of the shortest length possible for your configuration, such as this one: https://www.passion-radio.com/ksr400/rallonge-rpsmam-nm-1507.html

The guarantee does not cover breakdowns or defects resulting from

• Misuse or non-compliance with the rules of use of the equipment
• Projection or immersion of the equipment in water
• Incorrect adjustment, configuration or installation of the equipment or firmware
• Use of unofficial firmware
• Exposure of the equipment to an electrostatic field, e.g. thunderstorm, lightning
• Short circuit, reverse polarity, electric shock
• Use of the equipment outside the specifications and/or frequencies indicated by the manufacturer
• Damage to receivers caused by the emission of a signal in their vicinity
• Damage to the LoRA transmitter or power amplifier (PA) due to improper antenna adjustment (VSWR) or use outside the manufacturer's specified band or use without an antenna connected to the miner
• Total decrease or loss of returns and rewards (rewards, withness, crypto HNT)
• Use outdoors, in a non-ventilated, non-temperate, non-depressurised enclosure
• A failure of the Helium network and/or the blockchain

No 14-day return of a hotspot already declared on the Helium network will be possible, as the equipment will be considered as personalised by the user and impossible to resell as is.

FAQ about indoor ROCK Pi hotspots

What is the antenna connector on the hotspot?

The indoor unit is equipped with an RP-SMA female connector.

Is the 2GB memory sufficient for mining?

A hotspot in full activity consumes less than 1GB of RAM memory. With 2GB of memory the RockPi miner has enough RAM to operate.

A 4GB or 8GB hotspot will not perform any better than a 2GB hotspot with the same installation configuration.

The key point is the antenna, its tuning and line of sight.

What version of the RockPi hotspot do you have?

We only offer V2 with the correction applied.

Can I add 4G connectivity to my indoor hotspot?

No, the indoor unit does not allow the addition of a 4G modem. You can use a solution like a MiFi or a 4G to Ethernet module to achieve the same result.

How much internet data does the Hotspot use per month?

Currently, we estimate 30-50 GB per month.

Actual usage may be slightly lower or higher and will be updated as we start measuring more units.

As all hotspots become "hotspot light", data usage will decrease.

What antenna is included with the hotspot?

A 3dBi omni-directional antenna is included with the Nebra Indoor Hotspot, the specifications can be found in this manual.

Upgraded antennas can be purchased as an option below.

Can I use PoE power with this Indoor Hotspot?

If you wish to use PoE with the Indoor Hotspot, you will need an active PoE splitter that supplies 12V to the unit. You can also use passive PoE adapters as long as the power supply to the unit is between 9 and 16 volts and can deliver 15W of power.

How long does it take for my hotspot to synchronise with the network?

This time may vary depending on the speed of your Internet connection. However, in our tests, it takes approximately 24-48 hours for the initial sync to complete.

I have a problem with my device
