Nera MultiLink lllNera MultiLink III is an advanced point-to-multipoint(PMP) broadband wireless access solution,delivering high-capacity carrier class services.Nera MultiLink III is designed for new andestablished carriers requiring proven last milesolutions for small and medium businesses andmulti-dwelling and multi-tenant unit applications.In addition, Nera MultiLink III is the optimal solutionfor next generation cellular backhauling applications.

Nera MultiLink III provides a Carrier Class IP solutionover the air, including full IP and ATM QoS. Operating in the 10.5, 26 and 28 GHz bands, Nera MultiLink IIIoffers up to 36 Mbps net payload per customer premise equipment (CPE). Nera MultiLink III is fullyintegrated and can be collocated with the Nera MultiLink I system, using several identical outdoor unitcomponents and the same infrastructure, network management and planning tools.

Nera MultiLink III not only operates in the same environment as Nera MultiLink I, but can also reside onthe same cell using the same radio, efficiently providing varying bit ranges to a variety of user profiles.Both systems can be deployed on their own, or in tandem, by carriers operating in the licensedspectrum. The integration of the Nera MultiLink I and III enables new carriers to deliver the most efficientoverall solution to SME and large enterprise markets, facilitating high flexibility in service provision andcreating the ideal business model for the given market.
