"WiMAX "下一代無線寬頻傳輸技術主流
"Zigbee"網路效能提昇與評估
您絕對不容錯過的技術饗宴

QualNet令人期待已久的新模組Sensor Network支援IEEE802.15.4標準，也就是大家熟悉的Zigbee。Zigbee networks為無線個人區域網路（WPANs）定義較低的資料傳輸率、較長的電池壽命、與網路安全。Zigbee網路亦支援自動操作與遠端控制。QualNet中的Zigbee模組包含PHY與MAC兩層，以及下列幾點特點：

• Generating network beacons if the device is a coordinator.
• Synchronizing to the beacons
• Personal Area Network (PAN) association and disassociation.
• Carrier Sense Multiple Access with Collision avoidance (CSMA-CA) for channel access.
• Energy detection (ED) within the current channel.
• Battery model and RF energy consumption model.
• Link Quality Indication (LQI) for received packets.
• Modulation schemes:
  - O-QPSK with DSSS @ 2.4 GHZ, 868/915 MHZ.
  - BPSK with DSSS @ 868/915 MHZ.
  - PSSS with BPSK and ASK @ 868/915 MHZ.
