IEEE P802.15.4T-2017 pdf free.IEEE Standard for Low-Rate Wireless Networks Amendment 4: Higher Rate (2 Mb/s)Physical (PHY) Layer.
Change the second paragraph of 8.2.5 as indicated:The MLME-BEACON-NOTIFY.indication primitive is used to notify the next higher layer when a beacon or enhanced beacon is received during normal operating conditions.
The MLME-COMMSTATUS.indication primitive is used to notify the next higher layer that an error has occurred during the processing of a frame that was instigated by a response primitive. The MLME-PHY DETECT.indication primitive is used to notify the next higher layer that the 250 kb/s O-QPSK PHY has been detected during operation of the 2000 kb/s, 2450 MHz MSK PHY.
Add the following new subclause 8.2.5.4, including Table 8-14a, after 8.2.5.3 as indicated:
MLME-PHY-DETECT indication The MLME-PHY-DETECT indication primitive is used to inform the next higher layer that the 250 kb/s O-QPSK PHY has been detected.
Change the first paragraph of 10.1.2.6, including breaking the paragraph into two separate paragraphs,as indicated:
The MSK PHY 2450 MHz band uses channel page 7 with the channel numbers defined in Table 10-8 and Table 10-8a. A total of 42 frequency channels numbered 15 to 56 on channel page 7 are available in the band from 2400 MHz to 2483.5 MHz for the 250 kb/s data rate. A total of 16 frequency channels numbered 57 to 72 on channel page 7 are available for the 2000 kb/s data rate. Different subsets of these frequency channels are available in different regions of the world.
Compliant receivers operating at 250 kb/s shall implement all channels in Table 10-8, defaulting to channel 47 unless modified by higher layers. The multiple narrow channels for the narrowband MSK 2450 MHz PHY are specified in order to improve coexistence with other 2450 MHz services. Compliant receivers operating at the 2000 kb/s data rate shall implement all channels in Table 10-8a with no default channel.
Change the first paragraph of 18.1 as indicated, and insert the following figures (Figure 18-0a and Figure 18-0b) afier the first paragraph of 18.1:
The MSK PHY shall use the PPDU formats described in 12.1, except that the Preamble field is 32 symbols (4octets) and the bits in each octet shall be“10101010. In addition. when implementing the 2000 kb/s data rate. the PHR field is formatted either as ilustrated in Figure 18-0a or Figure 18-0b. depending on the value of the Extended PHR field defined in 18.1.2.IEEE P802.15.4T pdf free download.
