MechaTracks a Japan based tech inc launched the first CAT4 4G LTE HAT for the Raspberry Pi3.This enables 150Mbps download and 50Mbps upload speed structure.Raspberry pi on remote applications has been a area of interest for huge numbers as the IO pins helps out for various data processing collections.With the previous versions of SIM support for Pi being just about 375kbps which was found on many counter parts. MechaTracks resolved in providing a new support to RPi and naming it as 4GPi.Unfortunately, the cost ofsounds crazy asbut with competitors bugging around will make it ease of access in the coming days.The 4GPi is built around a SIMCOM SIM7600JC-H LTE Cat4 module. This works with LTE groups 1, 3, 8, 18, 19, and 26, which are generally utilized in Europe, South America, and Japan, Korea, Thailand, India, Australia, and New Zealand.The 4GPi incorporates dual external antenna, and seems to coordinate a miniaturized scale USB port. It underpins any Raspberry Pi with a 40-pins connector and incorporates passthrough pins and a jumper change to empower different HATs to be utilized on the same Pi.For instance, the board is intended to cooperate any 3D printer driver or any rasp-camera for recording can be easily mounted over it.But, as an Indian Embedded interest, this product doesn't make me buzz or raring to buy.In India, we already have JIO-Fi which is already a 4G-LTE module for 3G phone that can be used as modem or router in PC's.With this, I could connect my RPi3 tomaking all the above happen in just aboutWith 3G in way-out and 5G in way-in, 4G will change to supporting long-extend remote IoT applications, which commonly utilize 2G, 3G, or LoRa today.
