Design of 270 Mbps 2×2 MIMO-OFDM system for video streaming in internet of things

This paper presents designing of wireless local area network (WLAN) modem for video streaming in internet of things (IoT). Many concepts based on video streaming are introduced recently, and these systems need communication modem supporting high throughput for transmission of high quality of video. In this paper, WLAN modem using 2×2 multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) technique is designed. The proposed WLAN modem can support max 270 Mbps.

I. Introduction

Internet of things (IoT) is regarded recently as the most promising form of future wireless communication environments. Although there is no general definition about the IoT yet, many researchers have been studied to realize this IoT environment [1], [2]. Because each IoT application can need different requirement, for the selection of wireless communication technique in IoT environment, it is needed to specify the target system. Among many applications of IoT we focus on video streaming consideration which needs higher data rates than others [3]. Wireless local area network (WLAN) technique is suited to cover this high data rate and guarantee of quality of service (QoS) [4]. Therefore, in this paper, we design of WLAN modem using multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) technique for supporting max 270 Mbps.
