New High-Capacity Gateways Enable Scalable IoT Networks for Large Sensor Fleet Deployments

Salt Lake City—January 8, 2026—Monnit expanded its IoT infrastructure portfolio today with the launch of its ALTA^® Ethernet Gateway 4K and ALTA XL^® Ethernet Gateway 4K. The new gateways are purpose-built to support small to large-scale deployments of sensor fleets without adding network complexity.

Both gateways can support up to 4,000 long-range ALTA Wireless Sensors and can actively communicate with 1,000 sensors simultaneously per 24 hours through our iMonnit^® Software—no PC required. You can simply power and connect the gateways to Ethernet ports to quickly bring large sensor fleets online.

Designed for simplified deployment and administration, the ALTA and ALTA XL Ethernet Gateways 4K are ideal for organizations that need a distributed, high-capacity IoT network and extended wireless range options but require minimal sensor network management.

Streamline Large-Scale IoT Deployment

Our standard ALTA and ALTA XL Ethernet Gateways often require administrators to carefully balance sensor limits (up to 100 per gateway), configure multiple independent networks, or physically manage gateways one by one. The ALTA and ALTA XL Ethernet Gateways 4K eliminate those challenges by allowing multiple gateways to operate together as one logical network, dramatically reducing setup time and ongoing administration.

They were developed in response to customer demand from industries managing thousands of sensors across multiple sites, without wanting to micromanage individual networks and sensors. Organizations can preconfigure gateways and sensors before shipment, then deploy them across multiple locations.

Once powered on and connected to Ethernet, gateways automatically join the network and begin communicating with sensors in range—no PC, local server, or manual pairing required. This approach is particularly valuable for:

• School districts and universities deploying sensors across campuses
• Pharmaceutical and food manufacturers monitoring regulated environments
• Logistics providers managing cold-chain and mobile fleets
• Facility managers overseeing distributed buildings
• System integrators building scalable, repeatable IoT solutions

ALTA Ethernet Gateway 4K: Capacity Meets Simplicity

The ALTA Ethernet Gateway 4K is engineered to deliver reliable wireless performance and enterprise-grade security while remaining easy to deploy and manage.

Key capabilities include:

• Wireless range of 1,200+ feet through 12+ walls¹
• Supports in memory up to 4,000 sensors, with 1,000 active per day
• Frequency-Hopping Spread Spectrum (FHSS) for interference resistance
• Encrypt-RF® Security, including Diffie-Hellman key exchange and AES-128 encryption
• 30,000-message sensor memory² to preserve data during network interruptions
• Over-the-air (OTA) firmware updates for long-term platform support
• Plug-and-play Ethernet connectivity with onboard status LEDs

By removing the need for local computing hardware or specialized networking expertise, the ALTA Ethernet Gateway 4K enables teams to scale IoT monitoring quickly without increasing IT overhead.

ALTA XL^® Ethernet Gateway 4K: Extended Range for Demanding Environments

For organizations requiring greater wireless coverage, the ALTA XL Ethernet Gateway 4K adds a high-power transceiver that delivers up to 1 Watt of transmission power. This enables communication distances of 2,000+ feet through 18+ walls¹, making it well-suited for large warehouses, manufacturing facilities, campuses, and infrastructure-heavy sites.

Additional ALTA XL advantages include:

• Amplified receiver for improved signal reliability
• Enhanced performance in dense or obstructed environments
• Ideal support for mobile or roaming sensor fleets
• The same high-capacity network architecture and security as the ALTA Gateway 4K

Optimized for Modern IoT Network Management

To support this new level of scalability, the 4K gateways are optimized specifically for iMonnit and custom integrations. Local interfaces such as Modbus and SNMP were intentionally removed to maximize processing resources, memory, and performance for high-volume sensor networks.

Sensors dynamically associate with available gateways in range, allowing networks to adapt automatically as devices move, reconnect, or expand without manual intervention. This architecture enables organizations to confidently scale their IoT deployments while maintaining consistent performance and data reliability.

With the ALTA and ALTA XL Ethernet Gateways 4K, Monnit delivers a powerful foundation for organizations deploying IoT at scale—combining capacity, security, and simplicity into a solution designed to grow alongside modern operations.
