SK Telecom to launch 802.11.ax Wi-Fi

SK Telecom is preparing to launch a next-gen public Wi-Fi service based on the 802.11.ax, which offers up to 4.8 Gbps per AP. This is about four times faster than the Giga Wi-Fi (802.11ac Wave1, 1.3Gbps) that SK Telecom first commercialized in 2013.

'T Wi-Fi AX' uses four antennas to transmit and receive radio waves, and the available frequency bandwidth is 160MHz, which is twice the conventional Wi-Fi. The 2.4GHz and 5GHz frequency bands are used.

The latest Samsung Galaxy smartphones are equipped with 802.11.ax chips, and SK Telecom anticipates that other models will be as well.

"T Wi-Fi AX" is the first in Korea to utilize commercial APs that have been officially certified by the government. The AP received an electromagnetic compatibility certification from the National Institute of Advanced Industrial Science and Technology (AIST) at the end of August and final equipment approval from the Ministry of Information and Communication.

Broadcom ships 802.11ax Wi-Fi Access Point SoC

Broadcom has begun mass production of its WiFi 802.11ax SoC, the first in the industry to be fully compliant with the IEEE 802.11ax specification and the upcoming 802.11ax certification. 

The BCM43684 Max chip, which is Broadcom’s sixth generation Wi-Fi silicon, is aimed at the residential Wi-Fi market. NETGEAR is using the SoC with its Nighthawk product line.

“A little over one year ago Broadcom announced availability of Max WiFi products and committed to bringing the most advanced Wi-Fi technology ever implemented to consumers,” said Greg Fischer, senior vice president and general manager, Broadband Carrier Access, Broadcom. “Broadcom’s close collaboration with NETGEAR to enable 802.11ax-based Nighthawk routers will provide consumers with best-in-class Wi-Fi performance delivered using the very latest technology.”

SK Telecom picks Samsung, Ericsson and Nokia for 5G

SK Telecom Co. has named three vendors for its 5G network: Samsung Electronics, Ericsson, and Nokia.

Huawei and ZTE were notably excluded.

SK Telecom said it is on track to launch commercial 5G service in early 2019.

Polaris Wireless refines Z-axis wireless location tracking

Polaris Wireless, which supplies software-based wireless location solutions, has demonstrated the ability to locate wireless devices in the vertical dimension, or z-axis, within one floor level.

Polaris Wireless leverages available sensor inputs from devices and wireless networks to determine location. The company said its latest release also improves indoor horizontal accuracy.

“We continue to demonstrate the proven effectiveness and high accuracy of our indoor location technology,” said Manlio Allegra, Polaris Wireless CEO. “In emergency situations where first responders are trying to locate wireless callers in a high-rise building, the ability to identify which floor the call is originating from is essential.”

In early 2018, Polaris Wireless participated in

The company also released the following highlights from its recent participation in the CTIA’s Test Bed LLC Stage Z independent vertical location testing, which evaluated barometric-based solutions.  The FCC's Stage Z testing was conducted in San Francisco, Atlanta, and Chicago.
  • Polaris Wireless was one of two technology vendors selected to participate and was the only solution tested in all buildings in all cities. 
  • Polaris Wireless included the widest variety of device and barometric sensor manufacturers. The other participating technology vendor is a hardware-based solution requiring terrestrial beacons and firmware in devices.
  • The Polaris Wireless solution was tested in 3 cities, 48 buildings, 312 test locations, and 55,592 test calls. 
  • Polaris Wireless achieved a vertical accuracy of 4.8 meters at the 80th percentile, with a minimal one-time compensation of the barometric sensor outside of the test cities. 
  • Using actual test call data to emulate active sensor compensation, the Polaris Wireless solution improved to 2.8 meter accuracy at the 80th percentile, which exceeds the generally-accepted definition of floor level of under 3 meters.
  • Polaris Wireless achieved 25.8 meters of horizontal indoor accuracy at the 80th percentile, an improvement of 38% from CTIA’s Test Bed Stage 2 indoor testing for emerging technologies conducted in 2016.

“The Series B financing will allow Wasabi to expand internationally, continue to invest in our brand, and enable us to compete for the largest storage deals in the world. Our objective is to make Wasabi into one of the world’s most renowned cloud storage vendors,” stated David Friend, Co-founder & CEO of Wasabi.

Datrium raises $60 million for hybrid cloud, including Samsung funding

Datrium, a start-up based in Sunnyvale, California, raised $60 million for its Open Convergence platform for cloud builders.

The funding was led by Samsung Catalyst Fund, with participation from Icon Ventures, and existing investors NEA and Lightspeed Venture Partners. 

“We are thrilled to partner with Samsung and Icon Ventures to expand our technical and geographical momentum,” said Tim Page, CEO of Datrium. “Enterprises globally have the same problems in simplifying compute and data management across on-prem and cloud. Where SANs don’t even have a  path to cloud, traditional HCI has too many tradeoffs for core datacenters – backup requires separate purchasing and administration, and cloud DR automation is seldom guaranteed. Larger enterprises are realizing that Datrium software offers them a simpler path.”
