Aether RF radio technology for access control
A whitepaper from Aether RF
Access control messages are small, and every one has to arrive. Aether RF's engineering team explains how the radio in KNECT and the Wiegand Wave 150 gets them through obstructions and competing radio traffic.
What the whitepaper covers
- Why access control asks different things of a radio than streaming or file transfer
- How direct sequence spread spectrum recovers a message when interference disturbs part of it
- Frequency hopping, transmit power up to 1 watt, and the link budget behind usable range
- How the 900 MHz band compares with 2.4 GHz through and around obstructions
- Where the access decision is made in a bridge and in KNECT Core Access, and what that means for response time
- What a headline range figure leaves out about a real site
