NB-IoT and LTE Cat-1 are both licensed cellular uplinks for IoT products, but they are built for different jobs. NB-IoT trades throughput and mobility for link budget and battery life, while Cat-1 keeps full LTE speeds, voice support and handover. This guide compares the two, lists the parameters that break installations, and sets out the checks to run before a module is ordered.

Sub TextCommon-mode interference pushes both conductors of an RS485 pair in the same direction relative to earth, while differential-mode noise appears between the pair itself. RS485 receivers reject common-mode voltage inside a limited window, so ground potential differences, drive switching and shield grounding mistakes produce intermittent CRC errors. This guide separates the two disturbances, traces how each couples in, and gives the wiring and isolation choices that keep a plant bus running.
Zigbee and BLE Mesh both build low-power wireless networks for buildings and industrial sensing, but they solve routing differently. Zigbee, built on IEEE 802.15.4, maintains on-demand route tables and per-node roles; BLE Mesh relays at the advertising layer with managed flooding and no full route table. This guide compares both, covers provisioning, power and security, and ends with checks for choosing one.
Signal attenuation is every loss a real RF path imposes, from cable and connectors to mismatch and material in the way. Free space path loss is one calculated component of it: the loss caused by the wave spreading geometrically. This guide separates the measured total from the calculated term, shows how both are expressed in dB inside a link budget, and explains how to find which element is eating the range on an installed link.
