Communication and data transfer


mY: 218 mM: Gemini Sol:21 Time: 10:45 (Airy crater)


You walk along transportation path. People seem a little tired after next working day…

“This is decompression emergency alert for Sectors A, B and D. All citizens in sectors A, B and D please evacuate to nearest safety room. Airlocks will be closed in 2 minutes.”


Such announcement is a result of very complicated analysis of all technical issues, survival capability of the zone, AI evacuation routes estimation and finally data flow efficiency.


I am continuing my thoughts on technical services and maintenance. Today one of the crucial parts of our civilization – nerve system. Communication and data transfer.


Many engineers may find this article trivial. It is true. There are basic ideas given only. But please remember that among all technical issues the safety and comfort takes the first place. As an example – location of wired intercom consoles may save lives, if spread evenly all over the city.

Due to high electronics built-in – this system is a very expensive on. It will require a lot of ready made equipment or highly processed resource material to be brought from Earth (which makes it really „golden” one). Any mistake in planning will strike back in glitches in maintenance up to lost lives.


Communication and data transfer

I see a few network types that should be combined to provide proper information flow.

First, lets divide them into internal and external communication (div by location)

Second division , I see as diversity of primary functionality: public, technical and police/military.


By the term external communication I understand communication throughout the planet via satellites and communication towers.

In close proximity to the City – it would be required to provide fast data transfer (AI managing robots, sensors, and all the equipment). I see each tower also as a safety point for 2-3 people providing minimum amount of oxygen and power to sustain 1 full Sol. In the diagram I have marked as City activity zone – where all mining, processing facilities, solar panels fields, reactors, food, water production buildings are located.


Outside this zone less data connection will be available – so all the equipment must be independent and self manageable. If there are sites with long-term activities (research , additional mining sites) = there is no need to provide optical cables - the translation may be conducted via air with transfer priority channels for AI access and city management connection.


Loss of signal during sand storm can significantly influence the safety of those outside the city. It is crucial, that signal is to be provided at minimum 2 different spots (this of course increases the cost of the whole installation, so only via statistics of real emergency cases the coverage may be reduced)

Diagram below shows the idea:



Internal communication is the one inside the city premises (including all technical channels, communication routes etc.).

Diagram below shows the idea of communication devices types.



This is a sketch only, but it shows the principle: functional division of the network.

I see that public network may be sub divided into:


  • global announcement speakers,

  • wi-fi communication (as per mobile communication I assume it is less effective inside buildings and premises and it is much more expensive to provide proper quality, although it is suggested to provide devices that can serve both types of connection; wi-fi and LTE, especially in big volume spaces. I think in the future any smartphone

  • built-in wired intercom located in any public location (including transportation routes, airlock doors, every room with more than 3 people for permanent stay or work (more than 4 hours a day))

Technical premises - normally not available by people should be also provided with a good data transmission. I imagine that most of the works will be held by robots. They must be universal, to provide wide range of service with minimal amount of service units.

Therefore (in my imagination) there must be a big data flow to provide control for specific tasks. Of course this can be guaranteed only via AI management.


Also please note that Mars city must be a kind of smart home, but on a vast scale.

Typical smart home requires data flow from many sensors. Can you imagine data flow and storage for the whole city? 20 thousand smart homes? A million o smart homes? Such big data flow can not be even controlled by human beings.


But... we must to provide space for all those issues, we must provide networks and economical substantiation of all design decisions.

Often design focus on things grand and visible, but this one is crucial for people surviving but so tiny and unnoticeable that could be easily omit in overall budget and space planning.
