Connectivity Segment Dominance in the IoT Node and Gateway Market

Within the IoT Node and Gateway Market, the connectivity segment represents the single largest revenue-generating category, commanding a majority share driven by the diversity and criticality of wireless and wired communication protocols embedded in both nodes and gateways. The segment encompasses Bluetooth, Wi-Fi, Ethernet, Z-Wave, ZigBee, and a range of proprietary and emerging protocols, with each sub-segment serving distinct application environments defined by range, power budget, data throughput, and network topology requirements.

Wi-Fi remains the dominant sub-segment by revenue within the connectivity category, particularly in consumer electronics and enterprise IoT deployments where existing infrastructure lowers integration costs and where throughput requirements are non-trivial. The proliferation of Wi-Fi 6 and Wi-Fi 6E-enabled gateways has meaningfully expanded the addressable market, as these standards support higher device density — a critical specification for smart building and retail IoT deployments where hundreds of nodes must communicate simultaneously within a confined space.

Bluetooth and Bluetooth Low Energy occupy a complementary position, dominating short-range, battery-constrained node applications. Wearables, medical sensors, and asset tracking tags overwhelmingly leverage BLE due to its sub-milliwatt standby power characteristics. The rollout of Bluetooth 5.3 and the emerging Bluetooth Channel Sounding specification for precise indoor positioning are expanding the protocol's footprint into new verticals, including warehouse automation and smart retail.

ZigBee and Z-Wave serve distinct smart home and building automation niches, where mesh networking capability, low power consumption, and interoperability with home automation hubs are paramount. The adoption of the Matter standard — developed under the Connectivity Standards Alliance — has created a certification layer above these protocols, compelling gateway manufacturers to support multi-protocol architectures that can simultaneously handle ZigBee, Z-Wave, Thread, and Wi-Fi traffic. This is driving gateway bill-of-material complexity upward while opening premium pricing opportunities for vendors with robust protocol stacks.

Ethernet-based connectivity retains relevance in industrial IoT environments where deterministic latency and electromagnetic interference resilience are mandatory. Industrial Ethernet variants such as PROFINET, EtherNet/IP, and TSN (Time-Sensitive Networking) are seeing increasing integration into gateway products targeting smart factory and process automation applications.

Key players driving connectivity segment revenue include ARM, whose processor architectures underpin the majority of low-power IoT nodes across all connectivity sub-segments; Qualcomm, whose Wi-Fi and Bluetooth chipsets power a substantial share of consumer and enterprise gateway platforms; and MediaTek, which has aggressively expanded its IoT connectivity portfolio with integrated SoCs combining Wi-Fi 6, Bluetooth 5, and Zigbee in single-chip solutions. STMicroelectronics contributes through its STM32 microcontroller family and wireless connectivity modules widely used in industrial node applications. Cypress (now part of Infineon) provides BLE and Wi-Fi solutions embedded in thousands of IoT node designs across consumer and industrial markets.

The connectivity segment's dominance is not merely a function of its technical centrality — it reflects the commercial reality that connectivity silicon and modules represent the highest-value-added component in most IoT node bill-of-materials, with gross margins for certified wireless module vendors typically ranging from 35% to 55%. As multi-radio architectures become the norm and as cellular IoT (NB-IoT, LTE-M) penetrates previously Wi-Fi and ZigBee-dominated applications, connectivity segment revenue share is expected to consolidate further through 2028.

Key Market Drivers and Constraints Shaping the IoT Node and Gateway Market

The IoT Node and Gateway Market is propelled by a combination of structural technology forces and sector-specific demand patterns, while facing a defined set of constraints that create friction in adoption velocity and margin expansion.

Among the primary growth drivers, the industrial automation wave is quantifiably significant. Global spending on industrial automation technology exceeded $200 billion in 2023, and IoT node and gateway infrastructure constitutes a critical enabling layer for predictive maintenance, real-time process monitoring, and autonomous material handling. Each new automated production line typically requires between 50 and 500 sensor nodes and at least one industrial gateway, creating a multiplier effect on hardware demand.

The expansion of 5G network coverage is a second structural driver. With global 5G subscriptions surpassing 1.5 billion by end-2023, cellular-capable IoT gateways — which leverage 5G's network slicing for guaranteed QoS — are experiencing design-win acceleration across transportation, logistics, and utility metering segments. 5G's sub-6GHz and mmWave bands enable new use cases in real-time video analytics at the edge that were previously infeasible with LTE or Wi-Fi.

Government digital infrastructure mandates represent a third driver. The U.S. Infrastructure Investment and Jobs Act allocated over $65 billion for broadband expansion, portions of which are catalyzing smart grid and rural IoT deployments that require gateway infrastructure. Similarly, the EU's Horizon Europe program allocated €95.5 billion through 2027, with a significant fraction directed at IoT-enabled environmental monitoring and connected mobility.

On the constraints side, cybersecurity vulnerabilities in legacy IoT architectures remain a significant inhibitor of enterprise adoption. High-profile attacks on IoT endpoints have prompted regulatory scrutiny — including the EU Cyber Resilience Act — which increases compliance costs for node and gateway vendors and may delay product launches by 6 to 18 months for smaller players.

Fragmentation of connectivity standards creates interoperability friction, increasing integration costs for end users and slowing procurement decisions, particularly in verticals with heterogeneous legacy systems such as oil and gas and aerospace and defense.

Regulatory & Policy Landscape Shaping the IoT Node and Gateway Market

The regulatory environment governing the IoT Node and Gateway Market has intensified substantially since 2022, with multiple jurisdictions introducing binding security, interoperability, and data governance requirements that directly affect product design, certification timelines, and market access.

The European Union's Cyber Resilience Act, formally adopted in 2024, mandates that all hardware products with digital elements — explicitly including IoT nodes and gateways — meet defined cybersecurity baseline requirements before placement on the EU market. Manufacturers must conduct conformity assessments, maintain software bills of materials, and provide security patches for the entire expected product lifecycle. Non-compliance carries fines of up to €15 million or 2.5% of global annual turnover. This regulation is expected to consolidate the market toward larger vendors with compliance infrastructure, disadvantaging smaller OEMs.

In the United States, the White House National Cybersecurity Strategy (2023) and the subsequent IoT Cybersecurity Improvement Act direct federal agencies to procure only NIST-compliant IoT devices, creating a certification requirement that influences commercial market standards.
