ZigBee

Hardware development services

We have developed 2.4GHz, IEEE 802.15.4 compliant and multi-purpose ZigBee modules based on the following SoC:

• Texas Instrument's CC25XX chips

Key hardware development highlights:

• ZigBee to UART modules
• ZigBee to USB modules
• ZigBee and GPRS based data concentrators
• ZigBee enabled automation control modules / sensor modules
• ZigBee to Wi-Fi modules
• ZigBee to power line communication (PLC) modules

Key design considerations:

• Low power consumption
• Low form factor size
• Multiple antenna options to suit the range requirements

Advantages to you:

• Quick prototyping using IP developed by us – hence less time to market
• Initial development cost reduced by more than half

Embedded application development services

Along with proficiency on hardware, we have in-depth knowledge of network layer, device objects (ZDO), profiles, application framework (AF) and 128-bit AES encryption. Having all the expertise under one roof helps us in delivering quality ZigBee applications.

We have extensively worked on standard application profiles such as:

• Smart Energy Profile (SEP) 2.0
• Home Automation
• Building Automation

We have also worked on various clusters of ZigBee Cluster Library (ZCL) such as:

• Simple metering cluster
• Automation cluster
• Commissioning cluster
• Key establishment cluster

We have implemented Manufacturer Specific Clusters (MSP) for electrical metering solution.

Our application development profile includes development of ZigBee applications for:

• End devices for low power consumption and battery operated devices
• Routers to extend communication at network level
• Coordinators for overall network management communication

Key ZigBee application development includes:

• Development of a meter reading application using SEP 2.0, Manufacturer Specific Clusters (MSP) with end device functionality
• Development of safety and security application using home automation profile and standard / custom automation clusters and end device functionality
• Development of ZigBee routers with SEP 2.0 and home automation profiles
• Development of GPRS based data concentrators with SEP 2.0 and coordinator functionality
• Development of a ZigBee coordinator for hand-held units

Case study

Problem statement

There was a requirement of installing ZigBee enabled electricity meters for wireless meter reading across various locations in India. For most of the conventional meter suppliers, it was a mammoth task to suddenly convert their existing meters to the required ones! With the stringent time frames, building new meters from scratch with the required functionality was nearly impossible and very expensive. One of the meter manufacturers approached us for a technology solution and was lucky!

How Maven helped

Maven studied the existing meters and developed a ZigBee module that could be integrated with those. In a short span of three months we transformed the conventional meters to modern wireless meters. Key development highlights:

• An extremely small form factor to fit in existing enclosure of meters which was cramped for spaced
• Passed 30KV test
• Range
• More than 100 meters in line of sight
• More than 30 meters with obstructions
• Developed embedded application with
• SEP 2.0
• Simple Metering Cluster
• Manufacturer Specific Cluster for metering
• Extremely low power consumption
• Less than 200mA in operational mode
• Less than 5mA in sleep mode
• Designed and developed an automated test jig for production testing of thousands of modules everyday

Result

The tender bid was successful and order of 5 lakhs (0.5 million) meters was bagged.
