CDMA and EVDO

Even with LTE deployed, many of our clients still use CDMA for Circuit- Switched Fall Back (CSFB). The current generation of LTE handsets uses CSFB, which means they connect to the LTE network for data, but voice calls still use the 2G, 3G or HSPA+ networks.

For commercial Operators, it is important that your RF Engineers understand how to correctly design and optimize your network so that your subscribers’ experience is seamless. 4G Unwired has designed and optimized multitudes of CDMA and EVDO (1x Data Optimized) sites and we have the experience to design and integrate your new LTE network with your existing CDMA system, especially from a spectrum management and system performance perspective.
