Existing mobile phone networks into space
– Overview:
- Company developing technology to expand mobile phone networks into space.
- Plan to launch satellites that can communicate directly with ground-based mobile phones.
– Strengths:
Potential to enable the use of mobile phones anywhere in the world.
Contribution to regions with delayed development of communication infrastructure.
– Future Outlook:
Launch of satellites and commencement of services.
Collaboration with global telecom operators.
Business expansion in emerging markets.
Comparison between AST Space satellite phones and Starlink.
AST Space and SpaceX's Starlink are ambitious projects aiming to provide internet connectivity anywhere on Earth using satellite communications networks. However, there are several important differences between the two.
Differences in satellites and communication methods
– AST Space:
◦ Direct Connection: AST Space aims to achieve direct communication with satellites using existing smartphones without the need for special equipment.
◦ Low Earth Orbit Satellites: The goal is to provide more stable communication by placing satellites in relatively low orbits.
– Starlink:
◦ Relay Stations: In some cases, ground relay stations may be necessary between smartphones and satellites.
◦ Large-scale satellite constellation: Deploying thousands of satellites in low Earth orbit to build a large-scale network covering the entire globe.
◦
Purpose and Target of the Service
– AST Space:
◦ Development of communication infrastructure in underserved regions: Focusing on emergency communications in areas with undeveloped communication infrastructure or during disasters.
◦ Expansion of mobile phone networks: Expanding existing mobile phone networks into space, aiming to make mobile phones usable anywhere on Earth.
– Starlink:
◦ Broadband Internet: We aim to provide high-speed broadband internet services around the world.
◦ Various applications: Not only internet connectivity, but also applications in various fields such as IoT, telemedicine, education, and more are expected.
Current situation and future prospects
– Test phase: AST Space has already launched test satellites and is progressing with technological verification such as successful direct communication with commercially available smart phones.
– Collaboration with Rakuten Mobile: In Japan, Rakuten Mobile is aiming to start services domestically by 2026 utilizing AST Space's technology.
– Potential Markets: There are many regions in the world where the communication infrastructure is underdeveloped or where ground communication networks may fail during disasters. AST Space's technology holds great potential for providing communication services to these areas.
– Challenges:
◦ Building a satellite network: To provide stable global communications services, it is necessary to launch a large number of satellites.
◦ Cost: Due to the high costs involved in developing and launching satellites, the cost of services may become a challenge.
◦ Regulations: It is necessary to comply with regulations regarding communications in each country.
Penetration rate and monetization
– Penetration rate: Since the service has not yet started, there is no data on the penetration rate. However, once technical challenges are overcome and the service can be provided stably, rapid penetration is expected.
– Monetization: At the initial stage, there may be a possibility of high fees to prioritize the penetration of the service. However, with technological advancements and economies of scale, fees are expected to decrease in the future, leading to monetization.
Summary
AST Space's satellite phone service is still in the development stage, with many unknowns regarding penetration rates and monetization. However, the technical potential is high, and it is expected to become an innovative service that contributes to the development of communication infrastructure around the world.
