Platform communicates through Z-Wave technology based on MiOS. They provided Motion sensor, door/window sensor and smoke detecting sensor with system manufacturing company Fibar group and they are planning to launch IP-based equipment as Philips(lightening), Netatmo weather station(automatic temperature control), health care, wearable and etc.
NTT Docomo, Japan Company launched ‘Docomo Smart Home’ service in Mar., 2013. They provided the service that people can enjoy content focused on home entertainment connecting to smart phone, tablet, TV and various home appliances so that they can use at anywhere and anytime at home, unlike AT&T, Orange Company which focused on home security and automation [12] .
- 2.2 Study of Smart Home Automatic Control
According to the use of smart terminal became popular recently, the intention to use smart equipment about ‘security, home appliances, heath care and etc.’ tends to increase which can interlock with smart terminal [13] .
Zigbee is the representative technology of short-distance sensor network for the low power, low price, and easy use. In ‘smart phone-based home automatic control system design and realization’ [8] , requested message typed by user and remote-controlled equipment translate the order through request analysis device and give back the result to user or create the packet for sensor control and deliver to sink node. Zigbee Communication controls each equipment by sending signal to each control module of intrusion detection, gas sensing, gas valve, TV, lamp, air conditioner, lightening, automatic curtain, door lock, ventilation and etc.
M2M(Machine to Machine) or IoT(Internet of Things) will use in earnest through popularization of smart sensor, expansion of wireless network, price decline of communication module and spread of supply on smart equipment in hyper-connectivity era which everything is connected to human by network for smart home automatic control.
Instead of both sensor and smart equipment exchange information through internet, it is able to communicate through network interface equipped in smart equipment and sensor. This technology is highly important for IoT service [7]
In Fig 4 , those technologies which are wire mode USB as a direct communication way, Bluetooth as wireless way, IEEE 802.15.4 (Zigbee), RFID/ NFC, WiFi could be applied. It has an advantage to be built independent and personalized safe network by avoiding the internet access for communication and at the same time, it is strengthened in security and free from other network state.
