PiTalk 4G HAT - wireless communication module - shield for Raspberry Pi - SB Components 25985.
The module is based on the Quectel EG25-G 4G LTE system.
Main features of the Quectel EG25-G system
- Possibility to connect to a 4G LTE network with a maximum speed of up to 150 Mbps download and 50 Mbps data upload
- Additional support for 3G UMTS/HSPA+ and 2G GSM/GPRS/EDGE networks
- 2G backwards compatibility to keep you connected even without 4G or 3G coverage
- Support for MIMO technology, which increases the throughput of the wireless connection without expanding its bandwidth
- Support for DTMF and DFOTA technologies
- LGA package used in integrated circuits
- Designed for use in M2M and IoT technologies
- Very wide range of module operating temperature
Communication overlay for Raspberry Pi
This accessory is an additional module for the Raspberry Pi microcomputer that extends its basic communication functions with other devices or systems. A single-board Raspberry Pi computer does not always have sufficient ports and interfaces to support all types of devices and communications required by the user, so the use of such an overlay will significantly expand its capabilities. Installing the PiTalk 4G HAT overlay is relatively simple and involves connecting the GPIO pins of the microcomputer with the overlay and attaching the elements together using stabilizing holes. The compatibility of the systems allows the user to independently build a device with the features he requires.
The overlay is compatible with Raspberry Pi minicomputers.
The device enables the use of the 4G LTE wireless cellular network.
Support for 4G LTE mobile network
Support for 4G LTE networks by this device means fast and efficient Internet access . This allows you to quickly browse websites or watch movies in high quality. The speed of downloading and sending data (150 Mbps / 50 Mbps) allows the user to comfortably use his device in a wide range of communications.
Backward compatibility of 2G networks
The module has a wireless backward compatibility function that allows the use of older 2G cellular networks in places where the availability of 3G or 4G networks may be limited . This allows users to continue to benefit from a wide range of telephony and communication features, even in areas with poor coverage of newer mobile networks.
