8.8. 4G module
The 4G module enables the connectivity to high speed LTE, HSPA+, WCDMA cellular networks in order to make
possible the creation of the next level of worldwide compatible projects inside the new “Internet of Things” era.
This communication module is specially oriented to work with Internet servers, implementing internally several
application layer protocols, which make easier to send the information to the cloud. We can make HTTP navigation,
downloading and uploading content to a web server. We can also set secure connections using SSL certificates
and setting TCP/IP private sockets. In the same way, the FTP protocol is also available which is really useful when
your application requires handling files.
The module includes a GPS/GLONASS receiver, able to perform geolocation services using NMEA sentences,
offering information such as latitude, longitude, altitude and speed; that makes it perfect to perform tracking
applications.
The 4G module offers the maximum performance of the 4G network as it uses 2 different antennas (
diversity) for reception (MIMO DL 2x2), choosing the best received signal at any time and getting a maximum
download speed of 100 Mbps.
We chose the LE910 chipset family from Telit as it comprises the most complete 4G/LTE set of variants released
up to date. It counts with many different models, each one specifically designed for one market but all of them
with the same footprint:
•
LE910-EU (Europe/Brazil): CE, GCF, ANATEL
•
LE910-NAG (US / Canada): FCC, IC, PTCRB, AT&T approved
•
LE910-AU V2 (Australia): RCM, Telstra approved
