Implementation of a cable access point (CAP) device for ubiquitous network applications

This paper presents the implementation of a low-cost, data access-efficient, sample and easy to deployment, waterproof, and heatproof outdoor cable access point (CAP) device for ubiquitous network applications. The proposed CAP device is consisted of a cable modem (CM) and a wireless local area network (WLAN) access point (AP) to be integrated inside the chassis of an existing outdoor CATV amplifier. The main purpose of the CAP device is to effectively extend the coverage of outdoor wireless access link and to further provide a data access-efficient service for construction of a ubiquitous networking environment in the metropolitan area. Besides, to ensure the safety and validity for data accessing and information exchanging in the wireless broadband network, a security certifying mechanism of authentication, authorization, and accounting (AAA) is also integrated in the CAP device. The experimental results show that the performance and robustness of the CAP devices is suitable for ubiquitous network applications
