<p><u>This survey</u> <sup>1 </sup>fills in an important gap in the literature on CubeSat
communication systems’ designs and architectures. The paper <sup>2 </sup>comprehensively reviews the design details in-depth and
<sup>3 </sup>critically evaluates the performance and
reliability of the reviewed systems by analyzing the demonstration and
testing results and illustrating implicit assumptions in the reviewed works.
Furthermore, the paper <sup>4 </sup>proposes an original
CubeSat communication system categorization based on the design approach
and <sup>5 </sup>analyzes the features and limitations
of each category. Consequently, this leads to <b>identifying the
limitations</b> of current CubeSat communication systems and the <b>promising
future developments</b> that can boost CubeSat communications capabilities. </p>
