ZDC Wireless Successfully Deployed Managed WiFi Solution at Aztech Factory

Aztech factory build with modern state of the art facilities with a total investment of about 200 million Hong Kong dollars, with a total area of ​​41,000 square meters, total construction area of ​​42,000 square meters. 1200 workers working in the factory.



Established in 1986, Aztech a leading manufacturer and supplier of multimedia solutions for desktop PCs, with a strong global foothold in sound card and CD-ROM drive products. In the 1990s, Aztech advanced to the broadband and home networking arena, building on its core competencies in the design and manufacture of modems.Today, Aztech is a dynamic international group with key activities in Electronics Design & Manufacturing, LED Lighting, Materials Supply, Marine Logistics and Food Supply. The Group is headquartered in Singapore with support offices in USA, Germany, Malaysia, Hong Kong and China, as well as a vertically integrated manufacturing plant in China.


Aztech aim to provide more convenienceenvironment for all their employees by offering freeInternet access. With a vast area that need to coverage and 1200 employees that need wifi access are the key challenge of this project. 

  • WiFi coverage for 4 buildings (dormitory)

  • WiFi coverage for a dinning hall

  • WiFi coverage for a basketball court

  • Number of employee : 1,200

  • Min. -70dbm signal strength

  • Min. 200kbps of each user

  • Min 200 concurrent users at dinner hall

  • Internet access scheduling

  • Minimize the number of access point

  • Co-existing with current network devices

  • System alert to administrator via email


  • 1 x WS-5000-WS5 Controller 
  • 2 x ZN-1000-BS Outdoor smart WiFi AP 
  • 26 x ZN-7100-2DHO Dual radios dual bands indoor Managed APs




Product Features: 

  • Effective Seamless Wi-Fi Roaming.  Having ultimate control over your wireless access point, the AP controller is able to immediately adjust the wireless connectivity of one user to another Access point in a smooth transition if a user would be shifting his location (e.g. from one building to another).

  • Load Balancing. Instances wherein an access point accommodates too many clients, client connectivity can easily be transferred to other nearby  access  point  to  maximize  the  overall performance  of  each access point.

  • RF Management for Self Healing. In an event wherein an access point encounters a
    failure, AP controller can easily adjust the frequency provided by nearby access
    points to avoid connectivity disruption.

  • Power Over Ethernet. Maximizing the positioning of access points, the ZDC AP
    controller can easily provide both data and power through regular Ethernet
    cables, removing the constant need of providing power outlets near your access


Z-Com Selects Radisys’ TOTALeNodeB LTE-TDD Software for Its Small Cell Portfolio

Radisys’ design win supports LTE-TDD network deployment in China

HILLSBORO, OR, U.S. – September 16, 2013 – Radisys® Corporation (NASDAQ: RSYS), a market leader enabling wireless infrastructure solutions, today announced that Z-Com, a leading global wireless solution provider, has selected Radisys’ TOTALeNodeB™ small cell software solution to enable its small cell LTE-TDD (Time Division Duplex) network deployments in China. Radisys’TOTALeNodeB will enable Z-Com to deliver ultra-low cost and low power, high performance Enterprise domain small cells to its mobile operator customers serving dense urban environments, adding needed bandwidth and coverage.

Mobile operators in China are turning to LTE-TDD small cell technology to alleviate the strain on their networks, driven by the growth in mobile video and the pervasiveness of tablets and smart phones. In the mobile network, LTE-TDD leverages unpaired spectrum allowing downlink (DL) and uplink (UL) traffic to travel in both directions on the same frequency band. As most mobile users download content rather than upload content, Radisys’ LTE-TDD small cell solution provides a cost effective approach for operators to add capacity to congested areas and make more efficient use of their available spectrum.

“We selected Radisys’ TOTALeNodeB small cell software because of its expansive features set and clear roadmap for TDD support,” said Jim Gao, CEO, Nanjing Z-Com. “Radisys’ TDD solution supports integration on next-generation small cell silicon, providing us with a time-to-market advantage.”

Z-Com will roll out LTE-TDD trial deployments in the first half of 2014 for Chinese mobile operator, CMCC. The initial focus will be on the Enterprise small cell market, supporting 32-64 users.

“Radisys was first to market with LTE-TDD software stacks, and this design win is a testament to the industry-leading small cell software solution that Radisys brings to our customers,” said Todd Mersch, general manager, Software and Solutions, Radisys. “TOTALeNodeB provides Z-Com and its operator customers with a comprehensive LTE-TDD and field-proven FDD solution, enabling fast market entry and class-leading performance.”

Radisys will be showcasing its small cell solutions in Booth #P2 at LTE Asia, September 18-19 in Singapore. For more information on Radisys’ TOTALeNodeB small cell software, or to schedule a meeting with Radisys small cell experts, contact
