MIMO Techniques: 802.11n introduces smart radio technology to dramatically increase the quality and data rates by combining multiple antenna strategy with multiple simultaneous data streams. 802.11n systems uses MIMO (multiple input‚ multiple output) Fig. 1‚ techniques which can multiple transmit and multiple receive radio using its own antenna that also combine multiple streams of data of the same channel. 802.11n stations can multiply data rates using this spatial streams.

INTRODUCTION This project implements the concept of wireless technology and LED scrolling display to construct an energy efficient and versatile electronic notice board for institutional purpose. The system uses dot matrix LED panels to construct a horizontal display module in which any kind of messages can be displayed and scrolled. The message to be displayed can be send wirelessly from a remote computer with the help of wireless RF transmitter and receiver. This system is also equipped with
