In recent years, both wireless data broadcast (WDB) and hierarchical cell structure (HCS) have attracted the attention of the scientific community, yet they have been treated as entirely separate research topics. This paper presents one of the first attempts to bring the two subjects together. In particular, the paper deals with the issue of optimized data broadcast in systems of hierarchical cellular organization. We see the following as the main contributions of the paper: 1) considerably superior performance of HCS- over single-layerWDB systems is proven; 2) an algorithm for fast identification of the optimal broadcast schedule in HCS-WDB systems is proposed. As we are moving in the era of pervasive computing, where millions of devices - many of them of mobile and nomadic nature - will be requesting network support for retrieval of information, development of efficient wireless based transfer systems becomes immensely important.
