Abstract: This paper presents an integrated algorithm for efficiency assessment of wireless communication sectors. It is based on standard indicators as defined by the International Telecommunication Union (ITU), data envelopment analysis (DEA) for analysis and optimisation and principle component analysis for verification and validation. The DEA model is verified and validated by principal component analysis (PCA) and Spearman correlation technique. Eight standard indicators pertaining to wireless communication sector were identified from the ITU database. To present the usability of the algorithm, data for 42 countries with respect to three inputs and five outputs were collected through ITU. The results show weak and strong points of each country identifying, inputs or outputs having major impact on performance. This is the first study to present an integrated algorithm for efficiency analysis and assessment of wireless communication sectors.

Keywords: data envelopment analysis; DEA; wireless communications; efficiency assessment; principal component analysis; PCA.
