“…However, as mentioned before, the existing prediction models differ in their applicability over different terrain and environmental conditions [3]. As a result, existing path loss models have been adapted to different regions across the world, based on field measurement data [4]- [7]. Since most existing models have not been designed to suit Indian conditions, they do not provide accurate coverage estimates in an Indian scenario.…”

This paper interprets drive test based signal measurements in both urban and semi-urban Indian scenario using high-end smart phones with open source applications and highend spectrum analyzers integrated with planning and optimization tool provided by Tata Tele Services, a major Indian telecom operator. From the drive test results, we observe that the existing path loss models such as Hata, Okumura, COST-231-Hata and COST-231-Walfisch-Ikegami models are not accurate for Indian terrain conditions and a fresh study is required in this direction.

“…In rural region with thick vegetation of highly raised trees, some sequence of houses built with huts; and some part of the place with concreted buildings. Around 45% of the area filled with more huts, in contrast with suburban, which is combination of both counterparts [21], [26], [27], [30], [31].…”

To establish any mobile network system, the basic task is to foresee the coverage of the proposed system in general. Many such different approaches have been developed, over the past, to predict coverage using what are known as propagation models. In this paper, measurement based path loss example and shadowing parameters are applied on path loss models. Here, the measurements are carried out in urban, rural and suburban areas considering non-line-of-sight terrains with low elevation antennas for the transceiver (Tx) and receiver (Rx)[5]. The impact of multipath are more emphasized in the rural context. This causes higher probability of RF signal errors. On the basis of observation and with the help of clutter, we can present models which give better understanding for urban, rural and suburban regions in Karnataka state at 940 MHz GSM frequency[5],[26][13].

“…Arinda et al [11,12] have done similar works in Spain on digital TV broadcasting. We have carried some preliminary study on field strength with few measuring data in the north [13,14,15] and have studied the variation of the path loss using some models [16]. This paper is the continuation of research works done recently by us since 2005.…”

This paper is a thorough study of a digital television broadcasting system adapted to the small mountainous island of Mauritius. A digital TV LAN was designed with MPEG-2 signals. The compressed signals were transmitted using DVB-T and QAM modulators. QAM-16 and QAM-64 modulators were designed and tested with a simulator under critical conditions of AWGN and phase noises. Results obtained from simulation have shown that Digital video broadcast with a single frequency network (SFN) is possible in Mauritius with QAM-64 and QAM-16 modulators applying COFDM mode of transmission. However, this study has also shown that QAM-16 modulator had a better performance at low AWGN values (less than 12 dB) and can be adopted for Mauritius Island, provided that the number of transmitted channels is not high enough.
