WIRELESS CONNECTIVITY SPECIFICATIONS—WIRELESS MODULE
To determine which module the bed is equipped with, see “Wireless Connectivity” on page 88.
Internal Wireless Module is a separate module which has a separate Radio Transmission Equipment
Type Approval Certificate.
General Wireless Recommendations
The following are general best practice recommendations for establishing durable wireless connections
between the Baxter Radio and the customer’s wireless network:
Wireless Connectivity Specifications
The Wireless Connectivity module supports these security protocols:
Standards
• Wired Equivalent Privacy (WEP)
• Wireless Protected Access (WPA)
• IEEE 802.11i (WPA2)
Encryption
The Wireless Connectivity module supports these encryption protocols:
• Wired Equivalent Privacy (WEP, RC4 Algorithm)
• Temporal Key Integrity Protocol (TKIP, RC4 Algorithm)
• Advanced Encryption Standard (AES, Rijndael Algorithm)
• Encryption Key Provisioning Static (40-bit and 128-bit lengths)
•Pre-Shared (PSK)
• Dynamic 802.1X
• Encryption Options
• Off
Received Signal Strength
Indication (RSSI)
Baxter highly recommends a primary RSSI Value of better than or
equal to -67dBm and a secondary wireless signal of -70dBm or better
over the coverage area.
For proper Tx/Rx balance, RSSI readings should apply when APs are
transmitting at 25mW or less. The device radio transmits on average
up to 25mW power, limited by Regulatory Domain restrictions. The AP
signal strength and radio signal strength must be balanced, if not,
dropped packets and loss of connectivity can result.
Signal to Noise Ratio (SNR)
≥15dB. High noise level may cause dropped packets.
Jitter Packet-to-Packet jitter should be
≤400ms.
DTIM Set DTIM value to 1 (Wireless Controller default) for best performance.
SSID/WLAN Settings • Enable Session Timeout = Disabled
• Client Load Balancing = Disabled
• Client Band Select = Disabled
Ports Open • Remote Service Communication Server port 8883
• Remote Service Firmware Upgrade is handled through port 443
