SparkWave / System Configuration
Non-protected System
The basic system configuration is 1+0 without protection. In this case, a radio link has two single devices. The transmission path must meet the line of sight (LOS) condition. The link is not protected against equipment failure. The exception is when ring configuration or medium diversity systems are applied. Due to the very high MTBF, this configuration can meet almost all the availability requirements for access networks.

Stand-by System
In cases where very high transmission availibility and quality is required, more protection configurations are available. The simplest one is a hot stand-by configuration. In this case, all the parts of devices are doubled. Double antennas can be avoided by a power divider or by using a dual polarization antenna. Space or frequency diversity systems are used when transmission quality could be degraded due to multi-path propagation (fading). In all configurations, switching between the two receivers is without any loss of information (hitless).
