Wifi, Bluetooth, RF, IR

Wifi, Bluetooth, RF (Radio Frequency), IR (Infra Red) based development.

If you have any requirement regarding design and development based on Wifi, Bluetooth, RF, IR etc, get in touch with us and we will be glad to offer our superior service to you.

What is Wifi communication?

Wi-Fi is technology for radio wireless local area networking of devices like include desktops, laptops, video games, smartphones, TVs, audio players, printers etc. These devices can connect to the Internet via a WLAN (wireless Local Area Network) and a wireless access point normally called a Wireless Router. Wifi is positioned to be the backbone of IOT (Internet of Things) where small devices with Wi-Fi capability are able to connect to the Internet and add to a layer of smartness to themselves. 

What are the challenges with Wifi based product development?

Many popular devices are available in the market to make a product Wifi enabled such  as Esp8266, NodeMcu etc that gives a commonly used AT command set to give Wifi capability to the product. These devices can also be programmed directly using C, micro Python etc to give us the desired functionality.

Wifi based product development entails good knowledge of network protocols like TCP, HTTP, DHCP etc. Further knowledge of network security is a must. Wifi based products also need to be resilient to network outages, server downtime.

On the hardware front, Wifi based devices have a high power requirement and power management is often a challenge. Voltage difference between various devices is also a common challenge.

Our experience with Wifi based project development

We have very good experience of handling microcontroller based Wifi product development. The most common scenarios and challenges we have encountered in some project or the other. So our time to take the product to production is greatly reduced because the hard to visualize scenarios are already available to us.

What is Bluetooth communication?

Bluetooth is a wireless technology for exchanging data over short distances using radio waves. It is similar to Wifi, in that the hardware medium is radio frequency. Bluetooth devices normally connects to one more device, but it can connect to as many as seven devices.

Comparing to Wifi, Bluetooth is shorter in range, designed more for peer-to-peer communication and does not have straight forward Internet access capability.

Common uses of Bluetooth are communication between a mobile phone and a handsfree headset, car audio, speakers etc. It is also being used as a replacement to wires from GPS devices, barcode scanners, medical equipment etc.

Our experience with Bluetooth based project development

We have done projects involving Bluetooth. Do get in touch with us regarding any Bluetooth or Bluetooth Low Energy (BLE) based development work.

What is RF (Radio Frequency) communication?

RF or Radio Frequency is used refer to that form of wireless communication that use radio waves as the medium of communication. RF is infact the base communication system of Wifi and Bluetooth. But standalone RF is void of any protocol stack, fault tolerance etc. and is a bare bones form of communication between any two devices.

RF can penetrate walls and other obstacles. So devices that may not be in the same room can communicate with each other using RF. Commonly used RF frequencies are 315 MHz and 433 MHz

What are the challenges with RF communication based product development?

One of the biggest challenge with RF communication is that it is a system without any software protocol, feedback, collision detection etc. So all of these things have to be built in the product by the engineer. Of course the very low cost of the system and very low battery for continuous use requirements on the transmission side make it very attractive for low cost and low communication type systems.

RF receiver battery considerations are very important. And noise and collision detection is difficult to handle. Another very important challenge it being able to overcome transmitter and receiver oscillator timing differences.

Our experience with RF communication based project development

We have very extensive experience with bare-bone digital RF communication. We have very reliable and stable communication protocols that have been developed exclusively for small data exchanges. Our time to take the product to market is very small.

What is IR communication?

IR (Infrared radiation) is electromagnetic radiation with wavelengths longer than visible light. It is invisible to the human eye. IR communication is line-of-sight communication in which the transmitter and receiver need to be facing each other to be able to communicate. Contrary to RF, IR cannot penetrate walls etc and thus works only within the confines of a room. Common applications include remote controls, 

What are the challenges with IR communication based product development?

Like RF, IR based devices that are available in the market do not have any protocol etc. and thus is typically used for small data exchanges. IR suffers from getting weaker due to sunlight and thus systems that exposed to sunlight do not perform very well.

IR receivers that are available in the market are of type modulate and unmodulated each with its own benefits.

Our experience with IR communication based project development

We have designed applications like remote controls, visitor presence, production counter etc using IR.
