Samsung IoT access point supports Wifi, Zigbee and Bluetooth LE
November 24, 2015
Samsung Electronics is launching IoT access points (AP) that support multiple interfaces, including Wifi, Zigbee and Bluetooth Low Energy (BLE), as well as the industry’s smallest outdoor mesh AP.
South Korea-based Samsung has launched two types of wireless LAN product. The first is an IoT AP that supports Zigbee and BLE. The second is claimed to be an industry-first product that supports Wifi, Zigbee and BLE technology.
“The product was developed with the most careful consideration of the implementation of the highest level of technology so that problems such as interference did not take place when supporting Wifi, Zigbee and BLE technology,” said Deahyun Lee, principle engineer at Samsung’s networks business. “These three technologies use the same frequency range so problems such as data loss could occur when users use the three technologies simultaneously. To prevent such problems, interference control technology among Wifi, Zigbee and Bluetooth 2.4G communication technologies were developed and applied.”
Developing such technology meant success in intelligent control of the Zigbee device using local information received via BLE signals. For instance, the building management system detects the number of people on a certain floor by a BLE signal, which is widely adopted for smartphones, and controls the temperature of the floor by signalling the air conditioning system using a Zigbee signal. With Samsung IoT AP, there is no need to install an extra BLE beacon or Zigbee equipment.
“The IoT AP was originally planned with shopping malls, department stores and hospitals as the primary target market, where the BLE-based location services are required,” said Julee Lee, product planner at Samsung’s networks business. “To do this, after the product development was complete, a detailed analysis on the effect of the product was carried out on-site, by visiting large shopping malls nearby. As the first product in the industry to implement such technology, Samsung will be able to enter the smart building market with other illumination and air ventilation system industries that require energy saving.”
The IoT AP product integrates all Wifi technology required in an enterprise environment, in addition to integrating convenience, service optimisation and strong security. A wireless LAN product optimised for the IoT environment has been created.
Outdoor mesh access points allow the wireless connection of numerous APs, instead of using wired network cables. The advantages of an outdoor mesh system include eliminating physical restrictions and reducing the deployment costs.
The outdoor mesh AP launched by Samsung is said to be the smallest in the industry, but is still technologically advanced. With an environmental protection rating of IP67, the AP is safe from dust and debris and can be submerged in water up to one meter. At 2.8kg and 58mm thick, the product can be easily transported and installed.
“The outdoor mesh AP is used in diverse locations in corporations and urban environments,” explained Edric Kim, product planner. “This product can be deployed both indoors and outdoors so multiple environmental elements must be considered. For this reason, Samsung concentrated on implementing technology allowing easy deployment through a small design and easy notification of Wifi status through LED lamp. Moreover, to protect the product against bad weather conditions, Samsung outdoor mesh AP guarantees the IP67 certification, a rating higher than IP65, with its own waterproof and dustproof technology.”
Principal engineer Young-Cheol Ham addressed the test process in real environment. “This is a product developed after tests conducted in several locations within Korea, from boat race courses to embankments, to conduct various investigations on outdoor environment installations,” he said. “Such experiences helped us check the competence of the product, working more accurately under any environmental conditions. The strengths of this product are optimisation and recovery functionality among air time (own development) based on mesh-protocol based nodes (AP), provision of mesh service regardless of network topology (controller-based or local switching service mode) and utilisation of optimal wireless resources when transmitting data between accessing terminal.”
Samsung’s outdoor mesh APs are already installed in a lake park in Korea, and allow people to enjoy the speed of 1G wireless internet service, even outdoors.
