Embracing the LTE Network Era: Future-Proof IoT Solutions before the 2G/3G Network Shutdown
As countries worldwide plan to decommission their 2G and 3G networks, electronic engineers face the challenge of migrating their IoT applications to LTE networks. This blog post aims to guide engineers through this migration process, exploring various LTE options and introducing SIMCom's solutions to ensure a seamless transition.
Navigating through Alternatives: Identifying the Right LTE Standard
Venturing away from 2G/3G networks, a spectrum of LTE standards comes into the picture. Let's explore the following options:
LTE Category 1 (Cat.1)
Introduced in 2008, LTE Cat.1 is a wireless communication standard specifically crafted for IoT applications requiring moderate data transmission. Its favourable latency, enhanced power efficiency, and global roaming capability make it a fitting choice for a broad spectrum of IoT applications.
LTE Category 1 Bis (Cat.1 Bis)
The single antenna variant, LTE Cat.1 Bis, introduced in 2016, offers similar performance levels as LTE Cat.1, but with reduced size and cost due to antenna removal. It is well-suited for IoT applications with size restrictions such as wearables and healthcare monitoring devices.
Narrowband IoT (NB-IoT)
Designed for low-power IoT applications, NB-IoT offers extensive network coverage, power efficiency, and is perfect for devices requiring long battery life and operating in remote locations.
LTE Category-M (Cat-M)
Also known as LTE-M, Cat-M is a low-power, wide-area network solution offering higher data rates than NB-IoT. It is appropriate for IoT applications needing real-time data transmission.
Harnessing SIMCom's Solutions for Seamless Migration
SIMCom, a reliable partner during this migration phase, offers a collection of modules catering to the different LTE alternatives.
