You are a wireless communication specialist working with an
ambitious exploratory firm named PROJECT-SPACE. The firm is
embarking on a huge project to build a human habitat in planet
Mars. In 25 years, PROJECT-SPACE projected that the human habitat
will gradually evolved into a small space city with the population
of 1000 occupants. The initial habitat should be able to
accommodate 15 Martians with consistent, stable and reliable
communication from Mars to the planet Earth command center back in
the capital of the country.

1) How Internet, data rate, noise and bandwidth be sufficient to
achieve stable and reliable communication from Mars to S.I. for 10
people and able to scale up to 1000 people in the future?

2) How Martian atmospheric effect reacts to wireless signals?

3) How do you panned to power up your wireless access-points and
communication device?

4) What would be the time difference, latency (delay) in
communication based on your proposed data rate and bandwidth?
