The Sierra Wireless Q*4 is the replacement for Wavecom GR*4 and has a host of new features in the same popular, robust form factor as the GR*4, thus facilitating integration into existing product designs. If you appreciated the benefits of the GR*4, you will be able to continue using the form factor while taking advantage of the Open AT® Software Suite and our Intelligent Device Services, without discarding existing design efforts.
