UW-CM-08  
high-performance wireless mesh network module 
 
Product description 
 
The UW-CM-08 is a high-performance wireless module 
targeted at driving the communication part of high-end 
mesh networks. The UW-CM-08 has all functionalities inte-
grated in hardware and software to build robust and large 
wireless mesh networks.  
 
The UW-CM-08 is the compact version of Ubiwave’s suc-
cessful UW-CN-06 and comes in two different versions, the 
UW-CM-08-CP, with on-board chip antenna,  and the UW-
CM-08-XT, where an off-module external antenna can be 
used.  
 
The  features of the UW-CM-08 are aimed at performance-
critical applications in terms of reliability and the range of 
the communication. It further includes a variety of input and 
output functionalities. 
 
The UW-CM-08 is designed to be SMD-mounted onto a 
host PCB. SMD-mounting provides the best performance at 
the lowest cost. Additionally the UW-CM-08 was designed 
to occupy minimal board space. The host PCB would typi-
cally include sensor/actuator interfacing circuits as well as 
the power circuit.  
 
The UW-CM-08 communicates in the 2.4 - 2.4835 GHz 
unlicensed ISM band, and conforms with EN 300 440 
(Europe), FCC CFR47 Part 15 (US) and ARIB STD-T66 
(Japan). 
  
 
Applications 
 
•  Security and Safety Systems 
•  Healthcare Applications 
•  Asset Management 
•  Building & Home Automation 
•  Industrial Automation
 
 
Versions 
 
•  UW-CM-08-CP: version with  on-module chip an-
tenna. Ideally suited for all multi purpose wireless 
mesh solutions. Supports ultra-low-power applica-
tions, in combination with long transmission range 
•  UW-CM-08/XT: version where RF signal connects 
to external antenna; ideally suited for all multi pur-
pose 
wireless mesh solutions, requiring a metal 
enclosure.  Supports ultra-low-power applications, 
in combination with long transmission range. 
 
 
 
 
 
 
 
 
 
Radio features 
 
• 
Radio: IEEE 802.15.4 radio component, operating in 
2.4GHz ISM band 
• 
Channels: 16  
• 
Data rate: 250 kbps (PHY layer) 
• 
Antenna:  chip antenna or external. 
• 
Long range: Power amplifier up to 10dBm (ETSI) and 
up to 17dBm (FCC) extends range up to 100m indoors 
and 1km outdoors for a single link. 
 
Communication range (in meters, typical and max) 
measured with on-board ceramic antenna: 
In the presence of metallic objects, a shorter range can 
be observed. 
 
• 
Ultra-Low-Power: Nodes can operate for years without 
replacing batteries.
 
 
Additional hardware features 
 
• 
Designed for low-power: on-board power manage-
ment, including low-frequency clock source, various 
power-down modes. 
• 
Large amount of IO: 32 digital and analogue IOs, in-
cluding 8 channel 10 bit ADC, 2 UARTS, SPI, JTAG. 
• 
Cost-optimized compact surface-mounted module: 
only 35.5 by 16.5 mm, occupies only small board space, 
SMD technology does away with expensive connectors. 
• 
Robust and compact design: The surface-mountable 
module ensures robust, sturdy and compact integration 
on the motherboard. 
• 
Antenna flexibility: available in 2 versions, with choice  
between compact on-board chip antenna or external 
antenna on the mother PCB.
