LTE Modules

ML311X Series Multi-mode LTE Cat4 modules with HSPA+ and/or 2G fallback


ML3110/ML3111 series is a multi-band LTE-FDD and LTE-TDD, alone with DC-HSPA+ in a LCC package. With 3GPP Rel.11 and LTE Cat4, which provides data transfer up to 150kbps for downlink and 50kbps for uplink. ML3120/ML3121 series is the perfect choice for areas that do not yet have LTE coverage where backwards compatibility with 3G and 2G newwork is desired.

ML3110/ML3111 is able to utilize concurrent reception up to five GNSSS systems(GPS/GLONASS/BeiDou/Galileo/QZSS). It greatly improves accurate and reliable positioning information while simplifying the product design.

With abundant network protocols, ML3110/ML3111 integrates insustry-standard interfaces and suports extended operating temperature which can be widely used in telematics, security monitoring, industrial router, CPE, data cards, tablet etc.
