Microwave and compressed video systems had elements that were comparable from system to system. It was most difficult to estimate costs for fiber systems. There are more cost variables to consider, and these variables are not consistent between applications. If full motion video is necessary, microwave systems are viable alternatives for schools. Microwave systems are cost-effective and easy to install if the transmission distance is less than 10 miles.
Microwave is also the least expensive option for short distances.
Leasing microwave towers can decrease costs for two-hop systems, but leasing still requires a large investment. Microwave transmissions can be affected by weather conditions. Adverse weather can also inflict damage on microwave equipment. Microwave frequencies are not always available, and geographic topography may limit microwave feasibility. Compressed video systems offer the quickest and easiest solution for creating an ITV network between two schools.
