Implementation and Analysis of A Free Wireless Intercom System
Reference to "Implementation and Analysis of A Free Wireless Intercom System" by Ibrahim
Adabara et aL This study presents the design and implementation of a free intercom system that
operates using Wi-Fi in peer-to-peer (P2P) or WLAN networks. TI1e system utilizes packet
switching for communication between devices such as mobile phones, computer~. :and !P phones
without any physical witing. An Asterisk-based server facilitates real-time comtimnication, with
protocols such as Session Initiation Protocol (SIP) used for voice, video, and text:tnessaging. TI1e
system significantly reduces costs by eliminating the need for hard-wired intercoms or ptivate
branch exchanges (PBX), while also monitoring parameters like jitter, bandwidth, and packet
transmission. This paper serves as the basis for implementing Wi-Fi-based communication in the
proposed Deaf conununication system, ensuring accessibility and afford ability.
Design and Implementation of the DLNA Family Intercom System for ·smart Homes·
Reference to "Design and Implementation of the DLNA Family Intercom System for Smart o
Homes. By "Chin-Fcnf Lein and Hsien chaio Haung. TI1is work proposes an advanced family
