[1]: When the MC509 Mini PCIe module works in the range of –30°C to –20°C or +60°C to

+70°C, NOT all its RF performances comply with 3GPP2 specifications.
The thermal design must be implemented according to the chapter 6.8 . If not, the overheat

protection mechanism will be triggered due to overheated Mini PCIe and the network
connection will be terminated.
