Fuente: Wipo "IOT" The utility model discloses a based on NB the signal testing appearance of IOT network for to NB the detection parameter of the signal of IOT network is tested, include the shell and set up in the inside test module of shell, is does test template include the main control board, used for to be responsible for NB does the IOT signal carry out receiving and sending's NB IOT communication unit, be used for connect to mobile and NB do you IOT communication unit's bluetooth unit, be used for inserting NB the NB of IOT dedicated network IOTUSIM card and be used for receiving special NB IOT is segment signal's antenna frequently, NB IOT communication unit, bluetooth unit, NB the equal electricity of IOTUSIM card and antenna is connected on the main control board. Should be based on NB the signaltesting appearance of IOT network can be tested the property value on access network way. Adopt based on NB does the signal testing appearance of IOT network still include one kind based on NB the signal testing system of IOT network.
