  M2M Gateways can be deployed in the cloud or the on-premises. Each deployment type has its own benefits. For instance, cloud-deployed gateways offer a scalable and flexible options for businesses, while on-premises gateways provide more control and may be best for applications requiring low-latency processing.

• Functional Capabilities

  M2M gateways can be differentiated based on their functional capabilities, which may include protocol conversion, data processing, device management, network connectivity, security, and data management.

Functions and features

Despite the different types of M2M gateways, they have some core features and functions that enable communication between machines and organizations. The following table summarizes the main features and functions of M2M.

• Data Transmission

  A highlighted function of M2M is sending information from the machine to the M2M gateway for processing. This helps in the working of various applications which include sending alerts, monitoring environmental conditions and energy management among others. Different technologies like GSM, GPRS, GPS, RF, Bluetooth, and satellite are used for data transmission depending on the location, distance, and cost.

• Data Processing & Protocol Translation

  After the machine or device collects data, it must be processed and sent to a central location for analysis and interpretation. The data received at the M2M gateway is processed then translated and sent to a predetermined destination. Protocol translation ensures seamless communication between devices that use different communication standards.

• Security

  An M2M communication system connects different devices and applications over a network. It's susceptible to different types of attacks, such as data tampering and eavesdropping. M2M gateways provide messages between endpoint devices. They implement robust security measures to protect sensitive data transmitted between machines.

• Application Integration

  M2M technology enables developers to integrate various business applications into the system. Examples of applications include messaging, cloud computing, mobile apps, network management tools, and CRM. For instance, Energy companies can integrate their customer relationship management system with M2M gateway devices to monitor assets and respond accordingly.

• Device Management

  M2M gateway features make it possible to remotely manage, configure, and monitor devices connected to the network. They enable operators to add, update, remove, and activate or deactivate devices on the platform. Device management enhances the user experience by allowing them to troubleshoot issues before they adversely affect their operations.

  Every M2M device is unique. That's why effective management depends on custom configuration. Pay-as-you-go M2M platforms are flexible and scalable. They adapt to the specific needs of various users.

• Scalability

  Businesses and organizations that leverage M2M technology to enhance their operations often start small. They progressively add more devices to their network over time. Thus, they need an M2M gateway that grows with time.Easy addition of devices, maintain consistent performance, and adapt to evolving business goals.
