Directional RF antenna installations are not always done to carrier RF design specifications for azimuth, mechanical tilt and roll. Some before/after audits have shown that as many as 40% of antennas are installed more than five degrees off target. Using this audit data, simulations are possible with RF network propagation software and any market final design project. These results will prove that even when using conservative misalignment changes that induced network interference can be costly to carriers specifically for newer interference prone LTE technologies. Focusing just on carrier spectrum capital investment this number can easily become surprisingly high when considering large nationwide RF spectrum investments. The cost of ‘wasted’ spectrum due to interference does not, but could consider additional costs of ‘unused’ BTS/RAN infrastructure, unnecessary network performance troubleshooting efforts, less the credible output from RF propagation, ACP and SON tools , and more important, the effects of poor customer data experiences -all caused by misaligned RF antennas.
