Localized communication What I have learned... Multiplexing is the prosess by combing multiple signal at trasmitting number of recommend channel From 1G to 4G From GSM to HSPA+ Spectral efficiency focused on higher modulation Problem Localized communication Need of the hour Local to global Wired to wireless QPSK 8-PSK 16-QAM 64-QAM 3GPP - Governed by ITU-R Services Multi services Multi carrier wireless transmission system Duplexing is - way to transmit data - the process of activing two way communication over a communication channel - how to be listen and speak at the same time over communication channel

Summary Complexities in wireless channel Governed by ITU-R: manage the international radio-frequency spectrum ensure the effective use of spectrum defines technology families & allocate spectrum propose requirement for radio technology. Summary Solution • Divide geographical area into cells • Each cells are serve by base station • Frequency reuse • Packet Switch Network • Apply multiple access (FDMA, TDMA, CDMA, W-CDMA) • Multiple access technique • Multi carrier wireless transmission system • Multiple sub carriers of lesser bandwidth Guard bands / guard periode • Provided a set of sub carriers overlapping in frequency domain Complexities in wireless channel Multipath fading Delay spread Frequency selective fading Inter channel interference Scarcity of bandwidth Problems Wireless Communication Environment: • Time-varying transmission channel • Path loss/shadowing • Multipath fading • Doppler effect • Propagation delay • Security issue “Performance” of wireless network can be determined by: • Coverage : radius, mobility • Capacity : data rate • Quality : error rate

Thank you it’s good to know you all. Let’s keep in touch.
