We know that 2G and 3G terminal uses discontinuous reception in idle mode. In LTE the tradition has continued and we have similar DRX in idle mode but in addition to that we also have DRX in RRC mode. In LTE, when there is no data to receive or transmit in RRC connected mode, UE would switch off its transceiver for a very short interval. Jul 11, 2017 · eDRX for Better Device Battery Life. Also of note is the fact that the 02B version of the SARA-R410M module allows for eDRX (extended discontinuous reception). DRX is a mode which improves LTE by allowing devices to "sleep" between paging cycles, reducing energy consumption. lte edrx Shows the power profile of an LTE-M1 UE in eDRX Mode A normal LTE paging cycle is 1.28s, during which the device can be contacted by the network if traffic is queued for that UE (User Equipment - LTE lingo for the “thing” connected to the network). Extended Discontinuous Reception (eDRX) is a mode that improves power efficiency for cellular devices by reducing the chattiness between the device and the network. A normal LTE device is required to be active for a paging cycle every 1.28 seconds. An LTE device that leverages eDRX is only required to be active for a paging cycle every 10.24 ... eMTC or LTE-M? It is important to distinguish that eMTC is a sub-type of LTE-M network, often the two terms are used interchangeably. An eMTC Cat-M1 network is limited to 1.08 MHz channel width, and thus has a maximum data rate of 1 Mbps, whereas an LTE-M device may have a data rate up to 10 Mbps by using any existing LTE channel width.
