Interwrite™ PRS Hardware features
Two hardware types
Interwrite Learning provide two different hardware solutions with Interwrite PRS, so you can choose the solution that best fits your needs.
The small and low cost infra-red handset is ideal for classes
from 10 through to 50 students. The radio based handsets provide
support for larger classes (up to many thousands of students) as well as being well suited for use in smaller classes. The Interwrite PRS RF handset offers further input modes, including "self paced" and the "out of class" homework mode. The Interwrite PRS RF handset is approximately twice the price
of the Interwrite high-speed infra-red handset. The radio based Interwrite Cricket handset, is priced mid-way between the top end Interwrite PRS RF handset and the entry level Interwrite high-speed infra-red handset. Call us to discuss which solution is best suited to your situation
(see contact info at the bottom of the page), or ask
for a quote today on the system of your choice.
The sections below provide details of the radio PRS-RF, PRS-Cricket and infra-red systems.
