AMIT Wireless and D-Link both sit inside the Taiwan Steel Group, which means one corporate group covers two complementary connectivity portfolios: AMIT’s industrial and OEM cellular hardware, and D-Link’s networking, cellular and industrial switching. This guide maps the complete IoT and M2M product range across both brands, summarises each family, and shows which hardware suits which application.
AMIT and D-Link: one group, two connectivity portfolios
The two brands are sister companies rather than a merger. AMIT stays focused on industrial and OEM cellular connectivity: routers, gateways, remote terminal units and embedded modems built for years of unattended field service. D-Link brings a global networking brand with its own M2M and 5G cellular line plus a deep industrial Ethernet switching range. Between them the group can supply the cellular uplink, the local wired network and the management platform for a complete industrial or infrastructure deployment.
| AMIT focus | Industrial and OEM cellular: 4G/5G modems, M2M routers, IIoT gateways, RTUs, embedded modems, transit gateways, private-network (CBRS) units |
|---|---|
| D-Link focus | Cellular M2M routers and modems, industrial Ethernet switching, enterprise and SMB networking, cloud management |
| Group ownership | Taiwan Steel Group |
| Management platforms | AMIT A-NMS; D-Link D-ECS (Edge Cloud Solution), D-View, Nuclias |
| Typical buyers | System integrators, OEMs, infrastructure and industrial projects |
What this guide covers
How AMIT and D-Link fit together
AMIT is frequently mistaken for a D-Link sub-brand, but the relationship is one of shared group ownership, not acquisition. Both companies operate within the Taiwan Steel Group portfolio and function as sister companies, each keeping its own identity, product lines and market.
The division of labour is clean. AMIT was founded in 1998 and reports more than 50 million gateways shipped through partners and over 50 operator design-wins, built around industrial and OEM cellular engineering. D-Link, founded in 1987, is a global networking brand operating across dozens of countries, and now fields its own M2M and 5G cellular line alongside an extensive industrial switching range. For an IoT or M2M project the useful way to read it is one group offering two doors: AMIT for deep industrial and embedded cellular, D-Link for cellular plus the wired network, switching and cloud management around it.
The AMIT product range
AMIT organises its portfolio into six lines spanning the connectivity stack, from complete routers down to embedded modules. All are built for field-grade reliability: metal housings, wide-range power input, multi-network resilience and remote management through the A-NMS platform.

The D-Link IoT and industrial range
D-Link’s contribution to the group’s IoT story runs on two tracks: a cellular M2M line under the DWM name, and an extensive industrial Ethernet switching range under the DIS name, both managed through D-Link’s cloud and network-management platforms.
Cellular M2M routers and modems (DWM series and G530)
| Model | Type | Summary |
|---|---|---|
| DWM-311 | 4G LTE Cat.4 modem / bridge | Compact 4G-to-Gigabit-Ethernet modem and bridge for M2M, carrier certified. |

The whole DIS family is certified against vibration, shock and free-fall and ships with a 5-year D-Link warranty. In a group deployment, DIS switches provide the rugged wired backbone behind an AMIT or D-Link cellular router.
D-Link also fields the DBR business-router series for small business and branch connectivity, and the Nuclias cloud-managed networking platform, which sit alongside the IoT range for sites that need general business networking as well as M2M links.
Applications: matching hardware to the job
Because the two brands overlap and complement each other, most deployments draw from both. The table below maps common professional IoT applications to the group hardware that fits.
| Application | Group hardware that fits |
|---|---|
| EV charging and kiosks | DWM-311-G, AMIT IDG450, IOG gateways |
| CCTV, surveillance and smart city | AMIT IDG780, DWM-315, DIS-300G, DIS-200G (PoE) |
| Digital signage and vending | DWM-311-G, IDG450, IDG500 |
| Transport, rail and fleet | AMIT VHG760, VHG87B, DWM-315 |
| Utilities, energy and telemetry | IOG400, IOG700, IDG780, DWM-315 |
| Industrial automation and OT | AMIT IOG gateways, DIS-300G / DIS-700G managed switches |
| Retail and branch failover | DWM-312, IDG500, any dual-SIM router |
| Private 5G and CBRS | IDG500-C, IOG700-C, IDG450 (Private 5G) |
| OEM and embedded designs | AMIT MDG100, MDG200, MDG230 |
How to choose across the two brands
A quick way to narrow the range:
- Need cellular uplink for a single device over Ethernet: a modem or compact gateway (AMIT IDG450, D-Link DWM-311-G).
- Routing a whole site with SIM failover: an M2M router (AMIT IDG500 or IDG780, D-Link DWM-312 or DWM-315).
- Bridging industrial equipment, protocols or telemetry to the cloud: an IIoT gateway or RTU (AMIT IOG series).
- Building connectivity into your own product: an embedded modem (AMIT MDG series).
- In-vehicle or fleet: a transit gateway (AMIT VHG series).
- A rugged wired backbone behind the router: D-Link DIS industrial switches.
- Private LTE or 5G: the CBRS and private-network variants (AMIT IDG-C and IOG-C, IDG450 Private 5G).
Because both brands share group ownership, mixing AMIT cellular with D-Link switching in one project is a natural fit rather than a compromise.
