Power Management (PM) States in Single-Radio Technologies 2019/4/6

MAC States & MRPM Power Management or MAC states of single-radio technologies are important for MRPM which is about integrating power management of multi-radio mobile nodes State transition diagrams can be extracted from the standards that define MAC layer in each single-radio technology We also need power consumption values in each state Power consumption values depend on the manufacturer that implements the standards We have now values for various technologies: 802.11, 3GPP (EDGE), 3GPP2 (EV-DO) and WiMAX 2019/4/6

Wi-Fi Info All Ubiquity cards use Atheros chipset, even 900MHz card, rates <=24 have same power numbers. These are relatively efficient cards. http://www.ubnt.com/downloads/xr2datasheet.pdf Rx = 0.3W Mbps dBm W 24 28 1.3 36 26 1.2 48 25 1 54 24 0.9 http://www.ubnt.com/downloads/xr5_datasheet.pdf RX = 0.3W Mbps dBm W 24 28 1.8 36 26 1.5 48 24 1.3 54 23 1.1 http://www.ubnt.com/downloads/sr9_datasheet.pdf RX = 0.3W Mbps dBm W 24 28 1.1 36 26 1 48 25 0.9 54 24 0.8 Old whitepaper from Atheros, note Figure 1.2 and Table 1.1 http://www.atheros.com/pt/whitepapers/atheros_power_whitepaper.pdf MS native 802.11 pm http://msdn.microsoft.com/en-us/library/aa503136.aspx 2019/4/6
