The Technology Behind Lunar 4G/5G:

To appreciate Lunar 4G/5G, let’s briefly explore the technology underpinning it:

  1. Small Cell Towers: Lunar communication relies on small cell towers placed strategically across the Moon’s surface. These towers form the lunar network’s infrastructure, providing connectivity to assets like landers, rovers, and habitats.
  2. Advanced Antennas: High-gain antennas are used to transmit and receive signals between lunar assets and Earth. These antennas are designed to withstand the harsh lunar environment, including extreme temperatures and cosmic radiation.
  3. Software-Defined Networking (SDN): SDN technology plays a pivotal role in managing lunar network traffic. It allows for dynamic allocation of bandwidth, prioritizing critical data transfers and ensuring efficient network utilization.
  4. Security Protocols: Protecting lunar communication from cyber threats is paramount. Robust security protocols are integrated into the network to safeguard data integrity and confidentiality.


Nokia is set to launch a 4G mobile network on the Moon in 2023, with the goal of enhancing lunar exploration and potentially supporting human presence on the Moon. The network will be launched on a SpaceX rocket and will consist of an antenna-equipped base station stored in a lunar lander and a solar-powered rover. The network infrastructure will land on the Shackleton crater on the Moon’s southern limb and will be used within NASA’s Artemis program. Nokia’s network aims to demonstrate that terrestrial networks can meet the communication needs of future space missions, allowing for real-time communication, remote control of rovers, and high-definition video streaming. This development is seen as a significant step towards supporting lunar exploration and potential future mining operations, as it will provide critical communication capabilities and data transmission capabilities for lunar missions.

By the end of this decade, NASA aims to establish sustainable exploration on the Moon. High bandwidth, reliable connectivity and communications are a crucial component in making this ambition a reality. Future missions that require HD video, robotics, sensing applications, telemetry or biometrics will need the advanced capabilities that cellular networks enable, which is why NASA selected Nokia to deploy the first LTE network in space to test lunar surface communications for future applications. This is a challenge we relish – to deploy a network that will operate under the most extreme conditions imaginable – because when we push boundaries, the benefits of new technological solutions can be leveraged by our CSP customers in the networks that keep us going every day here on Earth.


Before the network can be put to work on the Moon, it needs to get there – undamaged. The launch will subject network hardware to extreme acceleration, shock and vibration forces. The network also needs to tolerate landing on the lunar surface.

As these challenges mainly affect the physical network components, mechanical hardening is needed to combat the effects of vibration, acceleration and shock. The mechanical design needs to be done in conjunction with the thermal design to ensure network equipment can operate on the Moon.

For this mission, the lunar lander’s payload is limited – with priority given to scientific equipment and the rover. Creating balance between the size and weight with the functionality and modularity of lunar network components will be essential.

The lunar network will optimally integrate hardware in one compact enclosure (e.g. an all-in-one network) using lightweight components. Software integration – the evolved packet core and baseband will run on the same board – will also help minimize the number of components, reducing size and weight.

Networks on the Moon will need to cope with extreme temperatures, lunar dust (highly abrasive), radiation and a lack of atmosphere (components need to operate in a vacuum). The choice of component materials will be critical to combat the Moon’s environmental conditions. Conductive and radiative cooling to keep components within their operating ranges. To mitigate radiation effects, components are tested for susceptibility to radiation-induced errors. Equipment will be hardened against environmental stresses and conformal coating can be applied for added protection.

All the operations and functions of the lunar lander and rover, in addition to the network and the device, will be solar and battery powered. The challenge lies in minimizing the network’s energy consumption. The lunar network’s software will be highly integrated into fewer electronic boards that share resources, resulting in overall less power consumption. Intelligent mechanisms like LTE Smart Scheduler will also reduce overall power consumption.

The Moon is 384,400km away from Earth. Sending support to fix issues or configure the network on-site is just not possible. If something breaks, who fixes it? Who deploys and optimizes the network upon arrival? The network must be designed to autonomously handle its own maintenance, deployment, configuration, and failures.

A network on the Moon requires capabilities for full autonomous operations, self-configuration, and self-healing. Operations and Maintenance (O&M) systems will be adapted to increase robustness to improve stability and 1+1 hardware/software redundancy limiting the impact of failure. Fast reboot capability is planned to provide quick recovery in the case of failure.

Reliable network connectivity on the Moon will facilitate various fact-finding missions critical to lunar exploration and NASA’s plan for long-term lunar presence. The challenge is establishing a stable and reliable wireless network, between the lander and the rover (or any other payloads or mobile users), given the lunar terrain characteristics, uncertain exploration areas and the inability to perform traditional site surveys and network planning.

Applications and Impact:

The lunar 4G/5G network will have a number of benefits. First, it will provide astronauts with high-speed internet access, which will allow them to communicate with each other and with Earth more easily.

Beyond the Moon

NASA and its partners are also considering the possibility of extending 4G/5G networks to other celestial bodies, such as Mars and Venus. This would open up new possibilities for scientific and exploration activities on these planets.

For example, scientists could use 4G/5G networks to transmit data from rovers and other robotic vehicles on these planets back to Earth in real time. This would allow scientists to study these planets in more detail and to make new discoveries.

Additionally, 4G/5G networks could be used to support future human missions to these planets. For example, astronauts could use the networks to communicate with each other and with Earth, and to access the internet.
