Does a rubber tapping machine need 4G/5G coverage?
Rubber plantations often have weak or no mobile coverage. For tree-mounted machines, the answer is a local radio network on site, with one internet connection at the controller for remote access.
No signal at the plantation — now what?
No 4G/5G signal is needed for a properly configured local LoRa group-control system. Where the plantation has no public 4G/5G coverage, an independent LoRa plantation network still allows normal centralized operation. Remote access from abroad needs one thing: if the on-site controller has internet access and a secure app connection, overseas users can monitor and send authorized commands. Individual machines do not need 4G/5G (product specification).
Local network on site, one internet connection at the controller
| Layer | Role | Needs 4G/5G? |
|---|---|---|
| Tree-mounted machines | Receive scheduled or app-issued tasks over local radio and report status | No |
| Local LoRa group-control network (with relay nodes where needed) | Connects the machines to the controller | No |
| On-site controller / gateway | Collects status; connects to the internet and to the app. One gateway serves up to 500 machines | Needs an internet connection — wired, 4G or other |
| App (remote) | Overseas monitoring and authorized commands via a secure connection | Internet access on the user side |

Has this been tested in a rubber forest?
- A 2026 paper in Agriculture deployed a hybrid mesh-star LoRa network of fixed rubber tapping machines and relay nodes in Baodao Xincun, Danzhou, and reported an average communication failure rate of 0.6% under normal and rainy weather[3].
- The study concerns fixed (tree-mounted) machines; it is not evidence for mobile robots.
And for mobile robots?
A ground-mobile robot carries its own navigation and control (see navigation without GPS). The published LoRa network evidence above concerns fixed machines, so communication arrangements for a mobile robot are specified per model and per project.
A note on maintenance schedules
Twice-yearly adjustment is a proposed maintenance schedule that can be discussed per project; it is not a universal standard for all models.
Frequently asked questions
Do tree-mounted rubber tapping machines work without 4G/5G?
Yes. No 4G/5G signal is needed for a properly configured local LoRa group-control system; individual machines do not need 4G/5G (product specification). A LoRa relay network for fixed machines was tested in a Danzhou rubber forest [3].
Can I monitor and control the machines from another country?
Yes, if the on-site controller has internet access and a secure app connection: overseas users can monitor the machines and send authorized commands (product specification).
Has LoRa been tested in a rubber plantation?
A 2026 study deployed a hybrid mesh-star LoRa network of fixed tapping machines and relay nodes in a Danzhou plantation and reported an average communication failure rate of 0.6% under normal and rainy weather [3].
