INTERNET OF THINGS (IoT) Modules and Systems 

September 25, 2016     

Dear ,

We are already developing and manufacturing some of (to our design or your design) the next generation Internet of Things devices in anticipation of current and future 5G applications.

We are already developing the next generation, high volume, LTE microbase stations, based on a multi-function MMIC, for lowest cost, highest integration level and smallest footprint, for example.

We are open to your requests (for proposal and quote) and suggestions for any volume potential module(s) to complete sub-systems with sensors, Including biometric, pressure and temperature etc.

With the changing scope of applications of internet shifting towards making physical world smarter there is no doubt that people will witness a shift in the number of connected devices soon. Within 5 years it is estimated that 50 billion devices will be online. What's more interesting is of these devices the mostly will be conventional physical objects. PCs, laptops and smart devices which dominate the internet at present will be dwarfed by these physical objects. The prerequisites of Internet of Things are many. Still the main components can be categorized into three categories i.e. intelligence, sensing and communication.

Internet of Things is going to sustain a $14 trillion market which means scope of this tech is now very large.

There is no limit to applications provided that the prerequisites of Internet of Things are met. Healthcare, personal security, home automation, industrial automation, traffic control and environment monitoring all can be done more efficiently using IoT technology.

Intelligence and Sensing

Wireless networks are utmost important for the success of the IoT infrastructure. Sensors should be able to communicate without constraints of physical wiring. It makes them more independent as well as increases their domain use. Sensing of capabilities of the IoT nodes should not only be efficient but also exhibit power use efficiency. The smart connected devices will be lying down dormant for most of the period. They will activate only when there is need to read or send data or to make a decision. In other words, 90% of their time sensors will not need power for relaying data or carry out any high power-consuming function. This requires the intelligent hardware to have ultra-low energy consuming sleep mode capability.

Smart Communication

To lower the power consumption by an IoT node only hardware changes is not the way. Smart communication protocols like ZigBee help in making exchange of data between devices less power consuming.


A low power consuming IEEE 802.15.4(2003) standard based specification, ZigBee is a brain child of 16 automation companies. What makes it novel is the use of mesh networking which makes utilization of communication resources much more efficient. ZigBee based IoT nodes can connect to central controller making use of in-between nodes for propagating the data. It makes transmission and handling of data robust.  
Bluetooth Low Energy (BLE)

Nokia originally introduced this protocol as Wibree in 2006. Also known as Bluetooth Smart this protocol provides the same range coverage with much reduced power consumption as the original Bluetooth. It has similar bandwidth with narrow spacing as used by ZigBee. Low power latency and lower complexity makes BLE more suitable to incorporate into low cost microcontrollers.

As far as application is concerned BLE is in healthcare sector. As wearable health monitors are becoming prevalent the sensors of these devices can easily communicate with a smart phone or any medical instrument regularly using BLE protocol.  

Counted as the most mature wireless radio technology, Wi-Fi is predominant communication technology chosen for IoT applications. Already existing protocols like WPS make the integration of internet of things devices easier with the existing network. If we talk about transmission then Wi-Fi offers the best power-per-bit efficiency. However power consumption when devices are dormant is much higher with conventional Wi-Fi designs. The solution is provided by protocols like BLE and ZigBee that reduce power consumption by sensors when devices are dormant.
Most important use of Wi-Fi is in the applications where IP stack compliance is needed and there is high data transmission. For instance in applications sharing audio, video or remote device controlling.

We can provide high quality, high volume manufacturing in the US, Malaysia and India as needed:

Once the module has been designed and tested, it is then moved into production, All assembly and testing from prototype to volume production are performed in a modern automated ISO Clean environment facility. All assemblers are fully trained in every assembly process, and committed to providing defect-free products and services on schedule every time. Components and work-in-process are stored in grounded, nitrogen dry boxes
