1. A communication system comprising a communication apparatus and a communication terminal configured to wirelessly communicate with each other,
wherein the communication terminal includes a first wireless communication interface including a plurality of antennas, and
wherein the communication apparatus includes:
an operation panel disposed on a front side of the communication apparatus,
a second wireless communication interface including a single antenna with a shield member for blocking a radio wave, and
one or more controllers configured to function as:
a unit configured to obtain angle information and field intensity information based on a result of reception of a plurality of radio waves, by the single antenna, transmitted from the plurality of antennas; and
a unit configured to transmit an establishment request for wireless communication to the first wireless communication interface via the second wireless communication interface based on the angle information and the field intensity information satisfying a predetermined condition,
wherein a position of the shield member and a parameter of the predetermined condition are prescribed so that, in a case where the communication terminal is positioned in an area on a rear side of the communication apparatus, the establishment request is not to be transmitted, and that, in a case where the communication terminal is positioned in a predetermined area on the front side of the communication apparatus, the establishment request is to be transmitted.
