Engineering Guides

We wrote these comprehensive guides to share what we have learned from hundreds of engineering projects. Each one covers the full technology landscape for its domain, with practical insights you can apply to your own projects.

The Complete Guide to IoT Product Development

We walk through the entire IoT product journey, from initial concept and hardware design through firmware development, wireless connectivity, cloud platform setup, and manufacturing at scale. This guide covers every decision point you will face when building a connected product, including component selection, protocol choices, certification requirements, and production planning.

NavIC vs GPS: What IRNSS Means for Tracking in India

We compare NavIC and GPS for tracking devices built for India: the IRNSS constellation, L5 and S-band signals, accuracy, the AIS 140 NavIC mandate, and the NavIC messaging service for fishermen. The guide explains when NavIC matters and when GPS alone is enough.

Choosing a GNSS Module for Your Tracker

GPS, GLONASS, Galileo, NavIC, and BeiDou compared, with the selection criteria that actually matter: TTFF, sensitivity, A-GNSS, dead reckoning, power, and antenna type. We walk through real module families from u-blox and Quectel and the hardware integration that makes or breaks reception.

NB-IoT vs Cat-M1 vs 4G for Asset and Vehicle Tracking

We break down the cellular IoT options for trackers: NB-IoT for deep-coverage stationary assets, LTE-M for mobility, and 4G for real-time and video. The guide covers power and battery-life implications, the 2G sunset, module choices, and a decision framework by use case.

Reducing Power Consumption in Battery-Powered GPS Trackers

Where the energy goes in a GPS tracker and how to cut it: deep sleep, PSM and eDRX, duty cycling, A-GNSS, store-and-forward, battery chemistry, and power-supply efficiency. We include the real math behind multi-year battery life and how to measure it.

Geofencing Explained: Types, Accuracy Limits, and Use Cases

Circular, polygon, and corridor geofences, on-device versus server-side evaluation, and the GNSS accuracy and hysteresis that determine whether your alerts are reliable. We cover dwell time, route deviation, speed-by-zone, and scaling to thousands of fences.

MQTT vs TCP for Telematics Device Communication

How trackers talk to the cloud: raw TCP and custom binary protocols versus MQTT and CoAP. We compare framing, QoS, keepalive, reconnection, store-and-forward, and the TLS and bandwidth cost on cellular, then show when each protocol fits.
