doc.: IEEE 802.15-<doc#> <month year> doc.: IEEE 802.15-<doc#> January 2016 Background Scope of the project: “This amendment defines a PHY layer enabling the use of the 865-867 MHz band in India. The supported data rate should be at least 40 kbits per second and the typical Line of Sight (LOS) range should be on the order of 5 km using omni directional antennae. Included are any channel access and/or timing changes in the MAC necessary to support this PHY layer.” Kunal Shah (SSN) <author>, <company>
