
[1]: When the ME909s Mini PCIe module works in the range from –40°C to –20°C or +60°C
to +85°C , NOT all their RF performances comply with 3GPP specifications.

The thermal design must be implemented according to the chapter 6.6 . If not, the overheat
protection mechanism will be triggered due to overheated Mini PCIe module and the
network connection will be terminated.
