In this paper presents a survey on RoF for Wireless Broadband Access technology like WiMAX (Fixed and Mobile). RoF is considered to achieve an effective delivery of wireless and baseband signal, and it also reduces the power consumption. In the other hand WiMAX (Worldwide Interoperability for Microwave Access) is recent fast growing broadband access technology through wireless. In this paper survey to possible, the RoF implement into wireless broadband access technologies like WiMAX. And also in this combination will be carried out different technical and keying concept from the different methodology.

A warehouse is a mercantile architecture for entrepot of stuff. Warehouses are used by producers, dealers, traders, wholesalers, distributors, customs, etc. The use of a smart WMS is the cherry on top of all of your smart technology. This warehouse should be screened at regular intervals to reduce storage cost of food grains due to atmospheric conditions and are documented. With the enlargement of business and the continuous requirements of the food product multiplicity, oldstyle granary management prototype will not meet that, due to its heavy capacity and low proficiency. To mitigate the manual labour work and to make the work easier, a smart warehouse is implemented which is enabled with several sensors and technologies. This paper intends to develop an IoT based smart warehouse monitoring system. The network of sensors includes vibration, humidity, temperature, fire sensors. It is done with the help of current technology (IoT). Raspberry pi controller adopts IoT technology to convey the messages. Based on the sensor’s data the appropriate data is captured and manipulated based on the limit given in the software and send timely information to the concern department officials of Central warehouse corporation through SMS for moderation and corrective actions arising due to atmospheric conditions inside the warehouse. The system developed has great advantages compared with the traditional model in terms of cloud storage of the warehouse data.
