MQTT based Push to talk application for Retail Stores

Having seamless communication on the showroom floor is always the key for smooth running Retail Store. This becomes even more critical for large square feet Retailers which are spread over thousands of sq ft. Many Retailers still rely on hardware-based Walkie Talkies. In addition to the walkie talkies being an expensive solution to deploy, it requires store associates to carry multiple devices to do their job, one device for scanning, item lookup and one device for walkie talkie. This paper proposes a software based digital walkie talkie app which uses the power of MQ Telemetry Transport (MQTT) for faster performance. This app can reside on company allocated device removing the need for an extra walkie talkie device carry. MQTT is a protocol for Internet of Things devices to communicate between themselves. This paper proposes using MQTT to cut down on client to server round trip costs and achieve faster and reliable communication. In the end paper shows results from a proof-of-concept built on MQTT protocol.
