39、rameters for the defined PHY 3 operating modes, the defined PHY modes that applied to different regions, appropriate 4 channel plans for each band, and any regionally specific PHY operating details, are defined 5 in this document. 6 Many of the PHY operating parameters are common across multiple pro

40、files, and many PHY 7 modes may operate in a variety of bands world-wide. The profile specifications define PHY 8 requirements for conforming implementations by reference to the PHY mode definitions in 9 this document. 10 11 12 13 14 ANSI/TIA-PN4957-100a 5 5.

47、odulation and Coding 6 The modulation for the FSK PHY is 2-level FSK. This section describes the symbol rate and 7 channel parameters for the PHY operating modes and the set of regional frequency bands 8 which may be supported in the profiles is as shown in Table 3. 9 The applicability of operating

48、modes to frequency bands is given in 2. All FAN devices shall 10 operate on at least one of the frequency bands as shown in Table 3. 11 12 A FAN device shall support Operating Mode #1 (in Table 2) for at least one of the frequency 13 bands specified in Table 3. For each supported band, a FAN device

49、shall also support 14 Operating Mode #3 (in Table 2) if the band supports channel spacing of at least 400 KHz. 15 16 5.6 Symbol rate and Modulation Index 17 This section describes all the operating PHY modes supported and respective modulation 18 index as shown in Table 2. 19 20 Table 2 PHY Operating Modes and Symbol Rates 21 PHY Operating Modes Symbol Rate (ksymbol/s) Modulation Index Operating Mode# 1 50 1.0 Operating Mode# 2a 100 0.5 Operating Mode# 2b 100 1.0 Operating Mode# 3 150 0.5 Operating Mode# 4 200 0.5 Operating Mode# 5 300 0.5 22 23 5.7 Frequ
