1. A REVIEW ON SMART CITY DEVELOPMENT & IMPLEMENTATION USING WIRELESS GSM MODEM

As cities continue to grow, numerous initiatives for Smart Cities are being conducted. The concept of Smart City includes a few ideas being administration, economy, the board, foundation, innovation and individuals. This implies that a Smart City can have different correspondence needs. Remote advancements like WiFi, ZigBee, Bluetooth, WiMax, 4 Gor LTE (Long Term Evolution) have introduced themselves as need might arise of Smart City drives. Notwithstanding, as the greater part of them employ unlicensed groups, obstruction and concurrence issues are expanding. In this paper, the remote advancements accessible these days for IoT (Internet of Things) in Smart Cities are presented. Our commitment is a review of wireless technologies, their comparison and the problems that difficult coexistence among them. In order to do so, the characteristics and adequacy of wireless technologies to each dom ain are considered. The problems derived of over-crowded unlicensed spectrum and coexistence difficulties among each technology are discussed as well. Finally, power consumption concerns are addressed .
