World’s First Semi-protected, 1.5+0 Configuration
Until now, system designers had two options for protecting equipment on microwave links. They could either not protect the radio equipment, an approach referred to as 1+0 (primary radio plus no backup radio); or they could fully protect the radio equipment with a second radio, an approach referred to as 1+1 or N+1 (primary radio(s) plus a backup radio).
Although 1+1 links are fully redundant, they come at a price that can be as much as 2x the price of a 1+0 link.
With the introduction of the Exalt's all-indoor EX-i GigE series radio systems, Exalt offers the world’s first semi-protected, 1.5+0 configuration, providing system designers with a protection alternative that balances system cost with redundancy. For a little more than the price of an unprotected 1+0 system, designers can now provide redundancy for the critical RF components.
The secret to this capability? Exalt Transmit and Receive Availability (EXtra™), a unique internally redundant architecture that provides integrated dual receivers for built-in receiver protection and/or built-in space diversity, transmit fail-safe switching and other redundancy features in a single system.
As mobile operators migrate their networks to LTE and as other network owners increasingly shift traffic from TDM to IP, redundancy requirements are changing and cost is paramount. The semi-protected, 1.5+0 option allows network designers to combine the inherently redundant nature of IP with RF component protection to strike an ideal balance between cost and redundancy.
