7.7.8. Write RXML that enables your AACR to learn the locations and incremental costs of SHF hot-spot nodes in the user s environment. Write a PERL script or Java program that uses this RXML to shape traf c for lowest cost or most timely delivery of large les. Explain how to enable the AACR to learn the best location for a palmtop video teleconference at, say, 128 kbps via CBR. Describe the training of the CBR. Implement this in Java, C, or PERL instead. Measure the costs of CBR fraining versus coding. 7.7.9. Write RXML for a Doppler-expert AACR. Implement the equations for estimating Doppler shift in C or Java. Write RXML for a Doppler(s, f, W) function. Explain how <Self/> with vision could identify objects in a <Scene/> that will affect Doppler shift. Implement RXML and inference to identify a large track producing Doppler-shifted multipath. 7.7.10. Write RXML for an AACR to know the Rayleigh distribution of signal strength. Explain how it uses that RXML to predict fade depth and duration statistics. Write Java or PERL that uses the RXML to adjust an adaptive equalizer to deal with 90% of the fades predicted for a 5.5 GHz ISM band. 7.7.11. Find a rule-based expert system shell or an authoring facility to interpret RXML to explain historical and current applications of HDR microwave radio to nonexperts. Write RXML for AACR to explain the low and middle levels of the SDH to nonexperts using the expert system shell. 7.7.12. Write RXML that enables the <Self/> to reason about SHF trunking. Write Java, JESS, or C to use this knowledge to con gure its processing, buffering, and interconnect for low capacity microwave trunking. Test the con guration in a simulated environment. 7.7.13. See the companion CD-ROM for exercises with microwave backbones and SHF antenna pointing.

EHF, the millimeter wave band, spans from 30 to 300 GHz. Terahertz frequencies then extend from 300 GHz to 3 THz. The terahertz bands are of use in medical diagnosis but not telecommunications. Free space optics (FSO) frequencies of 300 THz correspond to wavelengths of 1000 nanometers. Communications applications of FSO include the ubiquitous infrared data access (IRDA) port and the TV remote control. 7.8.1 EHF Physics-Related Knowledge Frequency band: 30,000 300,000 MHz Wavelengths: 0.01 m to 1 mm (millimeter wave) EHF propagation modes consist of direct and re ected LoS skywave with nearly complete attenuation from birds, clouds, rain, snow, and ice (except for nonlinear punch-through). Propagation can be very directional with little ionospheric scintillation.

7.8.1.1 EHF Propagation Knowledge Chunk Free space optics (FSO) and millimeter wave RF obey similar physical optics propagation characteristics with pronounced absorption by water and atmospheric gases. EHF is an ideal band for short-haul wideband communications systems via pencil-beams (Figure 7-13). Low data rate FSO re ects in small spaces for short range non-LoS links like TV remote control. Increased data rates require exact pointing with main beam tracking. EHF HDR have pencil beamwidths of fractions of a degree for 1 foot antenna apertures with pointing accuracy of milliradians over distances of kilometers. EHF carrier frequencies enable 100 Mbps to Gbps data rates with relatively low cost components. Using That Knowledge: The EHF-aware AACR knows the link budget equations of EHF/FSO communications. It models low data rate re ection modes and HDR pointing and tracking modes. It applies these models to predict and diagnose EHF/FSO QoI enhancement opportunities. 7.8.2 EHF Spatial Distribution of Energy

The spatial distribution of EHF energy is illustrated in Figure 7-13. 7.8.2.1 EHF Attenuation The atmosphere attenuates electromagnetic radiation through two distinct mechanisms: gaseous attenuation and absorption due to precipitation. 7.8.2.2 EHF Attenuation Knowledge Chunk EHF signals are easily attenuated by clouds, rain, snow, and ice [170]. Anything solid from buildings to birds blocks the radiation. Gaseous attenuation loss is less than 0.01 dB per km to 12 GHz. Water absorption peaks at 0.2 dB per km at 22 GHz, a candidate for low probability of intercept (LPI) data links. For longer ranges, the water hole of minimum absorption of 0.06 dB per km at 34 GHz attracts military multichannel and commercial T1/E1
