3. FAQs | IoT Gateway Development Services
Q1. What are the key features of your IoT gateway device solution?
Ans: Following are the key features of our industrial-grade IoT
gateway solution:
• Portable software code which is compatible with an array of
hardware platforms and OS
• In-built support for Over the Air (OTA) firmware and security
updates.
• Can be connected to a public or a hosted cloud server
• Supports horizontal and vertical scalability for future business
needs
• Secured connectivity via TEE (Trusted Execution Environment) and
TPM (Trusted Platform Module) modules
•Compatibility with Industrial IoT network protocols such as ZigBee,
EnOcean, IR, Modbus, Profinet
• Support for faster and data-efficient communication protocols like
Wi-Fi, Ethernet etc.
Q2. How do you ensure that you deliver a highly secure IoT gateway
solution for businesses?
Ans: At the core of our IoT gateway security mechanism is the Secure
booting process.
A secure boot can protect your IoT gateway device against security
and malware attacks . It ensures that your gateway device is booted
only by authenticated software.

Security of booting process can be ensured by :
• Boot source verification: The boot source is authenticated using
unique Secure Boot keys, everytime an IoT Gateway device is booted.
• Boot content verification: The boot file is verified and tested for the
accuracy of version while ensuring that only the authenticated
software is getting booted.
Other than the secure booting process, we also ensure security at the
following levels-
• Data communication ( from sensors to gateway as well as from
gateway to cloud)
• Network security
• Hardware security
Q3. Please provide more details regarding Data Security mechanism
in your IoT gateway solutions?
Ans: In our IoT gateway solutions, data security is supported by
following the below mentioned best practices:
i. Data Communication between Sensor Nodes and Gateway: We
integrate industry-recognized sensor communication protocols
including ZigBee, Z-Wave, 6LoWPAN, WiFi, LoRaWan– with our IoT
Gateway solutions. These protocols come with in-built security
features for secure and foolproof data communication.
Additionally, each of the data packets exchanged between the sensors
nodes and IoT gateway are also encrypted, based on your application
requirements.

ii. Data Communication with Cloud: Data communication between
IoT gateway devices and the cloud servers are secured through -
cryptographic key management, encryption , and security
certifications such as TLS or SSL.
Additionally, the IoT gateway devices communicate with the cloud
server using a unique MAC ID, assigned while communicating with
the server for the first time.
A MAC ID is used by the cloud server to ensure that connection
request is coming from an authorized IoT gateway device.
Q4. How is hardware security ensured?
Ans: At Embitel, we use Trusted Platform Module / TPM to assure
hardware security of IoT gateway devices. A TPM uses integrated
cryptographic keys to protect against data phishing attacks.
We use TPM to leverage the following benefits:
• Authentication of devices with the help of TPM’s unique RSA keys
• Easy generation, storage, and management of cryptographic keys.
Q5. Do you offer testing support for IoT gateway solutions?
Ans: Yes. Prior to the field deployment, we perform standard testing
of IoT gateway software. The testing process includes: Unit testing,
Integration testing, Functional testing, and System testing.

Additionally, depending on our customer’s application requirements,
we also execute: Vibration tests, Stress tests, Heat Chamber testing.
Get in touch with our IoT Consultants, who will assist you in creating a
suitable test plan for your IoT gateway development project.
Q6. What is the Load balancing strategy implemented in your IoT
Gateway solutions?
Ans: For load balancing, a “mesh network topology” consisting of
numerous interconnected IoT Gateway devices is created.
Such a cluster of IoT Gateway devices is positioned between a source
node /IoT sensor and a destination node /cloud server.
Whenever a failure happens at system/device level, the applications
and device connections are transferred to the nearest active Gateway
unit.
Q7. Do you have a backup mechanism to ensure continuous
availability of the IoT gateway without any downtime?
Ans: Yes. We have a temporary data back-up plan to ensure device
availability in case of a failure in the IoT network connection.
Whenever a network connection is lost, the data is stored temporarily
in a memory. As soon as the connection is re-established, this
available data is sent to the server.

Q8. I wish to integrate my legacy industrial setup systems with your
IoT Gateway solution – Can you help us?
Ans: In the past 11+ years, we have supported our customers, from
different industry domains and geographical locations, in retro-fitting
& integration of their legacy industrial automation systems.
Our innovative digital solutions have helped them save costs &
enhance operational efficiency.
Our team will create a suitable IoT roadmap after understanding your
industrial automation set up, in detail.
Post this, we will design efficient interface cards (between sensor
device to gateway & gateway to cloud) to enable communication with
your industrial assets for collecting relevant industrial data.
Once, communication established, this data is sent to authenticated
cloud servers through gateway devices for further processing.
