In parallel to the telecommunications revolution, yet based on the same techniques, new observation technologies are being developed, be it observation from space, the air or the ground. The three cordless applications originally intended were broadly (1) residential service, (2) PSTN access in highpopulation-density locations, and (3) wireless PABX for PSTN access in the office or business environment.

Unfortunately, the higher levels of modulation require higher values of carrier-to-noise ratio (C/N) to achieve a given BER. Figure 3.16 is a comparison of the error rates for several PSK and QAM systems. For a required BER, the C/N must be increased significantly as the level of modulation increases. The probability of error is Signal Processing for Digital Communications Q 16-QAM 101 N=4 155 Mb/s 4-LEVEL PAM 4-LEVEL S P MOD 16-QAM 64-QAM N=6 155 Mb/s 8-LEVEL PAM 8-LEVEL S P MOD 64-QAM N=8 155 Mb/s 16-LEVEL PAM 16-LEVEL 256-QAM S P MOD 256-QAM 155 Mb/s N = 10 S P PAM 32-LEVEL MOD 32-LEVEL 1024-QAM CONSTELLATION DIAGRAM 155 Mb/s N=n S P PAM 2 n/2 -LEVEL MOD 2n/2 -LEVEL 2n-QAM Figure 3.13 Higher-level QAM system configurations , cited: Carrier Grade Voice Over IP (Professional Telecom) Subsequently it was realized that domestic satellite systems could also be an attractive option at the national level. Indonesia, a country composed of thousands of islands, springs to mind as an example of cost-effective interconnection by satellite. There are now more than 50 countries using satellites for domestic (national) telecommunications. 271 Terms of Use 272 Chapter Six The broadcast nature of satellite communications is a unique feature that will probably prolong its survival even in the presence of intense competition from optical fiber networks ref.: Ss7 Basics read online
