HCIP-IoT case studies
HCIP-IoT · Put your knowledge to work in context.
HCIP-IoT is Huawei's professional-level certification for engineers who design, deploy, and operate Internet of Things solutions built around Huawei products and standards. It sits above the entry HCIA level and suits network engineers moving into IoT, solution architects scoping connected-device projects, and integrators who work with Huawei gateways, modules, and cloud services. The HCIP-IoT case studies are 5 cases and about 4,576 words.
1Choosing One Gateway SKU for Four Plants with Mixed Fieldbuses and an Unreliable 4G Backhaul
A discrete-parts plant in Suzhou needs to connect 180 CNC machines to a cloud platform. Of these, 140 expose only Modbus RTU over RS-485 at 9600 bps, 8 data bits, no parity, 1 stop bit, with a 1 s response timeout; 25 speak Modbus TCP on a flat 192.168.10.0/24 plant VLAN; the remaining 15 are older machines with pulse outputs that maintenance currently reads by hand.

A 900-bed hospital wants to track 1,200 movable assets across a nine-floor tower: 600 infusion pumps, 300 wheelchairs and 300 high-value surgical instrument trays. Nursing managers must locate a pump within two minutes and only need room-level accuracy.

A municipal utility is deploying 6,000 smart water meters and wants one radio technology for the whole city. Area A is the dense old town: meters sit in concrete pits roughly 2 m below grade, field measurements show RSRP around -128 dBm and SINR of -6 dB at pit level, and there is no mains power at the pits.

An appliance maker has 8,000 connected washing machines in customers' homes and plans to reach 200,000 within two years. Today each machine publishes to a self-managed MQTT broker on topic device/{imei}/data with a 400-byte ad-hoc JSON payload every 30 seconds; nothing is modelled, so every dashboard is a hand-written parser.

A cold-chain logistics company operates 20,000 trailer tracking units built by a contract manufacturer. Every unit leaves the factory with the same pre-shared key compiled into firmware, an unlocked UART console protected by a documented password, and an MQTT client that connects to the cloud broker on port 1883 with no transport encryption; the integrator argued that TLS would not fit in the 256 KB flash budget.
