IoT(Internet of things) is a concept where everyday objects are connected using Internet. There are wide ranges of objects or devices connected to the internet everyday and it’s growing exponentially. Here objects can be anything such as phone, refrigerator, car, headphones, lamps, wearable devices, house-holding items (Home automation devices) and anything else you can think of (even a human being!). The relationship or communication will be between people-people, people-things (objects) & things (objects)-things (objects). The devices connect to the internet using different modes of communication like WiFi, Bluetooth, iBeacon, Zigbee Wireless, NFC. Generally mobile phones are used as a medium through which the devices communicate to the internet. Hence, the data collected by these devices can be accessed from anywhere and the devices can be controlled from anywhere using web browser and/or mobile phones. Thanks to powerful hardware and software platforms available on the mobile phones.
At Cumulations an IoT apps development company in Bangalore, India, we clearly understand the role mobile apps play in connecting the devices to internet. You might be building the next generation fitness band or you are the largest weigh bridge manufacturer or might be an expert in designing home automation gateways, our mobility services will help you to connect your devices to internet. Hence transform your 'Devices' to ‘Smart Devices’.
We have gained expertise in building Android and iOS apps for IoT using different channels like WiFi, WiFi direct, Bluetooth Low Energy, Bluetooth 2.0, iBeacon, Zigbee and NFC.
Wi-Fi is a wireless networking technology to communicate between sender & receiver using radio frequency technology. Wi-Fi is intended to provide high speed internet without physical connections. Wi-Fi defined as wireless local area network by Wi-Fi Alliance. Wi-Fi can be used by personal computers, cameras, phones, tablets & etc to transfer. These Wi-Fi enabled devices can be connected to internet through wireless network access point.
Benefits of using Wi-Fi for enterprise IoT applications over other wireless networking technologies
Infrastructure already exists: Most of the organizations/companies embraced Wi-Fi as their basic necessity. As told that IoT apps involve less frequent data transmission and limited data, it will not demand for additional settings. IoT applications are simple applications run on mobile phones and they will receive data from similar thing which are embedded with electronics, software, sensors etc.
Security: When compared with other wireless networks, Wi-Fi provides the robust security and also transparent implementations.
It costs less, low power consumption, easy to implement, maximum capacity & high throughput .
Wi-Fi direct is also called as Wi-Fi P2P, which connects devices with each other without help of a wireless access point. Wi-Fi direct can be used for internet browsing, file transfer, and communication between devices at typical Wi-Fi speed. Wi-Fi direct connects devices from different manufacturer as well.
Basically bluetooth paved a way to exchange data between unwired entities in a revolutionary fashion when compared to lets say IR( where we had to literally keep entities very close to each other).
Bluetooth Low Energy/Bluetooth Smart
Bluetooth smart uses 2.4GHz radio frequencies as classic Bluetooth & a single radio antenna can be shared by dual-mode devices. According to applications range of the radio can be optimized. Manufacturer can optimize range to 200 feet and beyond with Bluetooth smart, especially in home automation applications where longer range is required.
It’s an industry- standard wireless protocol which supports multi vendor interoperability. The ability to create a dedicated data channel for IPv6 communication has removed the process of assigning IP addresses for Bluetooth devices.
Bluetooth Smart features:
Zigbee also called as high-level communication protocol , which creates personal area networks using low-power digital radios. Compared to WPANs, Zigbee is intended to be less expensive and easy to implement. The applications range from wireless switches to traffic management system.
Since it consumes less power, it limits data transmission from 10 to 100 meters depending on environmental anomalies. Zigbee uses mesh(star & tree) networking technology to reach more distance. Since it uses mesh networking style, consumes low power and low-cost, it intended to use in development of long battery life devices. Zigbee focuses on wireless and sensor networks in IoT & M2M.
NFC is one of wireless communication technologies out here in the tech world. This set of communication protocols communicate with electronic devices, in which one device would be a movable device such as smart phone to achieve near field communication by bringing them within 10cm each other. NFC is successor of RFID. Compare to Bluetooth, NFC takes less set-up time.
NFC is more secured than Bluetooth due to it’s shorter range.
There are 3 modes in which NFC operates:
iBeacon is Apple’s technology standard, which allows mobile apps(both iOS & Android) to listen & react for signals from beacons in the real physical world. Beacons are small wireless devices which send radio signals uninterruptedly. The mobile apps (smart apps) will receive and react to these signals via BLE technology. It tracks indoor behavior and helps in indoor positioning (even GPS cannot provide). Applications areas are retail, marketing, connected homes & etc.
We have been successful in connecting our customer’s hardware devices to the internet using these channels. Also at Cumulations, we understand the best practices in device-to-app communication and the best practices of the IoT and Wearable industry.
