What is a High-performance 4G LTE Cat M1 Antenna?

The High-performance 3dBi SMA Antenna Cat M1 Antenna rubber duck antenna style CTRF-ANTENNA-AP-8221-13158-SMA antenna item is an LTE Cat M1 Antenna manufactured by C&T RF Antennas Inc. The 13x158mm plastic housing omnidirectional portable antenna Cat M1 antenna is designed for IoT and M2M applications.

What is Cat M1?

As a founder of LTE, the 3GPP organization has always used the Internet of Things as an important evolution direction of LTE.

As early as 2008, the first version of R8 (Release 8) of the LTE, in addition to the terminal level of Cat.3, Cat.4, and Cat.5, which satisfy broadband multimedia applications, there is only 5Mbit/s. The terminal level CAT.1, can be used for “low rate” applications such as foundations.

Notice! The CAT here is not the meaning of the cat, which is the meaning of Category, “type, classification”. Cat. x is that UE-CATEGORY and the UE is a user equipment. Cat.x This value is used to measure the wireless performance of user terminal devices, which is used to divide the terminal rate (level).
Different CATs, different rates

At the beginning of the development of LTE, Cat.1 did not be concern by the industry. As wearable equipment is gradually popular, Cat.1 is gradually attached to the industry.

However, Cat.1 terminals need to use 2 antennas, which still “require too high” for wearable equipment with extremely high volume sensitivity (generally equipped with one antenna).

Therefore, in R12 / R13, 3GPP has been optimized for the Internet of Things.

The first is to increase the new terminal grade Cat.0 in R12, and give up support for MIMO (multi-antenna), simplifying half-duplex, peak rate is reduced to 1 Mbit / s, and the complexity of the terminal is reduced to 40% of the ordinary LTE terminal. . In this way, the cost requirements of the Internet of Things were initially reached.

However, although the channel bandwidth of the Cat.0 terminal drops to 1.4 MHz, the radio frequency reception bandwidth is still 20 MHz (too large).

Thus, 3GPP adds a Cat.M1 level in R13, the channel bandwidth and the radio frequency receiving bandwidth is 1.4 MHz, and the complexity of the terminal is further reduced.

Cat.m1 is eMTC. This is the source of eMTC.
