7. 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

8. 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
