About the Renaissance Receivers and Responders
42
When students use their Renaissance Responders, they
have multiple Renaissance Receivers to choose from, and
they are all named “Renaissance Receiver.” Why is this
happening?
This means that multiple Renaissance Receivers are within range of the
Renaissance Responders, and the Receivers have not been given unique
names. To change the name of a Receiver, see page 9. Enter a name that is
unique. For example, if the teacher’s name is John Smith, give the network
the name “Smith’s Receiver.”
How many Renaissance Responders or NEO 2 laptops can
be used with one Receiver at the same time?
Up to 300 can be used with one Renaissance Receiver.
What is the range of a Renaissance Receiver (how far away
from the Renaissance Receiver can a student with a
Responder or NEO 2 sit)?
Up to 150 feet.
Will students have to point their Responders or NEO 2
laptops directly at the Renaissance Receiver in order to
get their responses accepted?
No. The 2Know! classroom response system uses Radio Frequency (RF)
technology, which is not blocked by line-of-sight obstructions. The answer is
recorded as long as the device is within the range of the receiver (up to 150
feet).
What radio technology does 2Know! use?
2Know! operates in the public 2.4 GHz band, the frequency used by WiFi,
Bluetooth, and other wireless devices. The system uses standard IEEE
802.15.4 modulation and communication protocols to avoid interference with
other devices operating in the same area.
Will the system hop to an open channel?
Renaissance Receivers and responders include logic to select a clear channel
from the 15 available channels when the Renaissance Receiver is started.
