Beginner Topic 10 of 50 Mobile, Embedded & IoT

Mobile Networking

Handling intermittent connectivity and APIs.

How it works

Mobile apps communicate over cellular and Wi-Fi networks that are slower, higher-latency and less reliable than wired ones, with changing connectivity as users move. Apps typically use HTTPS APIs with JSON or Protocol Buffers, WebSockets for real-time data and background transfer services. Good practice includes caching, request batching, compression, retries with exponential backoff, offline queues, adaptive quality for media, pagination and detecting network state. Platforms impose rules such as App Transport Security and restrictions on background networking.

Where it is used

Social feeds, messaging, streaming, maps and any app with a back end must handle the realities of mobile networks.

Common pitfall

Assuming constant fast connectivity leads to spinners, failures and data loss. Frequent small requests keep the radio awake and drain battery. Large payloads cost users data plans. Handoffs between Wi-Fi and cellular break connections. Certificate pinning errors and captive portals confuse apps. Design for offline-first, sync when connected, show cached data quickly and test with network throttling.
