	3.8. LTE MTC (example of a potential candidate)		3.8. Comparison between 6lo Link layer technologies
	LTE category defines the overall performance and capabilities of the
	UE (User Equipment). For example, the maximum down rate of category
	1 UE and category 2 UE are 10.3 Mbit/s and 51.0 Mbit/s respectively.
	There are many categories in LTE standards. 3GPP standards defined
	the category 0 to be used for low rate IoT service in release 12.
	Since category 1 and category 0 could be used for low rate IoT
	service, these categories are called LTE MTC (Machine Type
	Communication) [LTE_MTC]. And 3GPP standards defined the MTC
	Enhancements in release 13.
	LTE MTC offer advantages in comparison to above category 2 and is
	appropriate to be used for low rate IoT services such as low power
	and low cost.
	LTE MTC can be used for tracking services, such as asset tracker,
	bicycle/cat tracker and etc with national wide. LTE MTC can be also
	used for monitoring & control service, such as car mobility record
	and weather observation that require much more traffic than other IoT
	services. Since the traffic collected by other IoT devices such as
	LoRa, Z-wave and BLE is small, LTE MTC can be used as a bachhaul of
	other IoT networks.
