Abstract

The invention provides a communication terminal device and a communication system, capable of improving the robustness of communication when a plurality of communication terminal devices are concurrently connected. The communication terminal device (1) is a glasses-type communication terminal device (1) having an optically transmissive display mounted thereon. The communication terminal device includes two RF modules (2a, 2b) that perform high-frequency signal processing; and a baseband module (3) that is connected to the two RF modules (2a, 2b) via communication lines so as to be communicable and that performs baseband signal processing. The two RF modules (2a, 2b) are selectively switched by the baseband module (3) to perform a reception operation. When one of the two RF modules (2a, 2b) performs the reception operation, a reception signal received by the RF module is retransmitted from the other RF module.

Description

Technical field [0001] The present invention relates to a communication terminal device and a communication system. Background technique [0002] The utilization of enhanced reality (Ar: Augment Reality) feature enhanced reality (Ar: Augment Reality) function is expanded to enhance the realistic perceptual experience. As a communication terminal device (hereinafter also referred to,,,,,,,,,, [0003] In order to implement the AR function, it is necessary to frequently collect vast information such as dynamic image information between the terminals. Therefore, millimeter wave communications such as WiGIG (registered trademark) capable of performing high speed and large capacity, such as WiGig (registered trademark). [0004] Patent Document 1: Japan Special Table 2013-507604 [0005] In recent years, a broadcast distribution service that is considered as follows: For example, in the area of ​​the concert hall, the game and other arena, the multi-AR terminal broadcast (Broadcast) t...
