634 -The NB series has the feature for Multi Sampling and one uplink. See one of them

637 -
638 -User can use this feature for below purpose:
639 -
640 -1. **Reduce power consumption**. The NB-IoT transmit power is much more higher than the sensor sampling power. To save battery life, we can sampling often and send in one uplink.
641 -1. Give more sampling data points.
642 -1. Increase reliable in transmission. For example. If user set
643 -1*. **AT+TR=1800** ~/~/ The unit is seconds, and the default is to record data once every 1800 seconds (30 minutes, the minimum can be set to 180 seconds)
644 -1*. **AT+NOUD=24** ~/~/  The device uploads 24 sets of recorded data by default. Up to 32 sets of record data can be uploaded.
645 -1*. **AT+TDC=7200**  ~/~/ Uplink every 2 hours.
646 -1*. this will mean each uplink will actually include the 6 uplink data (24 set data which cover 12 hours). So if device doesn;t lost 6 continue data. There will not data lost.

651 -
652 -There are many different providers provide NB-IoT service in the world. They might use different band, different APN & different operator configuration. Which makes connection to NB-IoT network is complicate.
653 -
654 -If end device successfully attached NB-IoT Network, User can normally see the signal strengh as below (between 0~~31)

664 -(% class="lead" %)
665 -When see this issue, below are the checklist:
666 -
667 -* Does your SIM card support NB-IoT network? If SIM card doesn't not specify support NB-IoT clearly, normally it doesn't support. You need to confirm with your operator.
668 -* Do you configure the correct APN? [[Check here for APN settings>>http://wiki.dragino.com/xwiki/bin/view/Main/General%20Configure%20to%20Connect%20to%20IoT%20server%20for%20-NB%20%26%20-NS%20NB-IoT%20models/#H2.1GeneralConfiguretoattachnetwork]].
669 -* Do you lock the frequency band? This is the most case we see. [[Explain and Instruction>>http://wiki.dragino.com/xwiki/bin/view/Main/General%20Configure%20to%20Connect%20to%20IoT%20server%20for%20-NB%20%26%20-NS%20NB-IoT%20models/#H2.2SpeedUpNetworkAttachtime]].
670 -* Check if the device is attached to Carrier network but reject. (need to check with operator).
671 -* Check if the antenna is connected firmly.
672 -
673 -If you have check all above and still fail. please send console log files (as many as possible) to [[support@dragino.com>>mailto:support@dragino.com]] so we can check.
