For MTSMC LTE models, refer to the MTSMC-Lxx Device Guide for antenna information.
Antenna System for Cellular Devices
Cellular/wireless performance depends completely on implementation and antenna design. Integrating the
antenna system into the product is a critical part of the design process; it is essential to consider it early so your
product design does not compromise performance. If you change the SocketModem's certified antenna system,
specific network carriers, such as Sprint or Verizon, require product recertification. The antenna system is defined
as the UFL connection point from the SocketModem through the specified cable to and including the specified
antenna.
PTCRB Antenna Requirements
There cannot be any alteration to the authorized antenna system. The antenna system must maintain the same
specifications. The antenna must be the same type, with similar in-band and out-of-band radiation patterns.
