Exclusive Implementation of ۲.۵G LMRS for theFirst Time in Iran: A Case Study in KhorasanRazavi Electric Power Distribution Company

Having the longest medium voltage overheadlines in the country and an area of ۱۱۷۰۰۰ square kilometers,the electricity distribution company of Khorasan Razaviprovince is a leading communication category company.Maintenance and repair operations on medium and low powerlines are carried out by ۳۱ electricity management offices usingtheir own communication systems between vehicles, groups,and centers. As part of its recent experiences, this company hasmoved from first-generation (analog) land mobile radio system(LMRS) systems to second-generation (digital) systems andinto third-generation (software integration) systems. As aresult, radio coverage has improved by ۳۸%, SAIDI hasreduced by ۴۸%, maintenance cost has decreased by ۲۰%, andmore than ۵۰۰۰ calls that were created in the single month canbe made in only one city. There are several other advantages tothe second generation network created, including thepossibility of the integration of communications with otherorganizations, the creation of various hierarchical groups suchas crisis and managers, as well as instant text messaging.Additionally, a number of additional benefits are provided,including high-quality voice calls, double the amount ofbandwidth available, data security via encryption,compatibility with analog networks (۱G), roaming capabilities,the ability to make private-public-group calls, and the abilityto manage users and equipment via software applications.Also, in this project, speech recognition of calls with artificialintelligence (AI) and therefore automatic ۱۲۱ work orderinsertion are some of the advantages.
