This paper is based on an exploitation of a femtocell as small scale network for home and office which utilized white-spaces available in spectrums. It is normally free spaces available when spectrum is not in access mode; since such free spectrum normally may present because of incomplete channel used. Now in case spectrum utilization under femtocell service user is promptly knows to be a primary user which required turning in to secondary user. Since primary user having accessing mode mostly of license frequencies, such user need to scan on Dynamic Spectrum Access technique for unlicensed frequency for communication setup under femtocell secondary network. In a proposed paper Scanning is done through controller section, heart of femtocell architecture so that Scalable and configurable property of it can be possible when data centric server system is operated using Linux base. Hence on TDM base messages and data can be routed under certain priority basis. Design challenge leaning become not to change in existing hardware of primary user; while using services provided by femtocell.

In this paper we present the integration of sensors for ad hoc applications using Wi-Fi connectivity in order to achieve reconfigurability and scalability of a project infrastructure management. Many of the user equipment will be shifted based on varying purpose and reconfiguring projects. Apart from strategic sensors, infrared observation systems, movement estimators, proximity sensors, there are several static sensors which also need to be relocated based on purpose driven reconfiguration. It has been found that several scenarios of reconfiguring the sensors exceeds the ZigBee dimensions and they need to get resorted to the design of Wi-Fi based information exchange. In our design, based on bandwidth utilization of the sensors, we engage a low power Wi-Fi system-on-chip (SoC) based on IEEE 802.11 standard. The chip is used to interface with the low bandwidth sensors and for the case of network surveillance cameras where the video streaming is occupying larger bandwidth, a cognitive radio design approach is engaged.

“…From the above design work still it need to interface with switching unit so that relay unit will give the proper channel to communicate in between SU client. Here Cypress [7] CYWM6935 module it is interfaced with switching unit and GUI interface is created in PC to observe the scanning information. Using the relay all FAP points will be getting access to scanned free white spaces, these scanning is done in Active and Passive mode for initial and dynamic way.…”

In this paper an adaptive white-fi spectrum deployment of a Femtocell as small scale private network for home and office is intended. Its design is underlay to utilized white-spaces available from empty or partial empty channels typically received RSSI > -70dB above strength of the white-fi spectrums. Core key is to establish service in between local to another local user's which works on the available Wi-Fi network. Here the Role of local user to communicate between all other users, likely the others too. Since the local user is using its mobile or cell phone then the network for the local user is of two type's primary and secondary, in which he is one the user who comes under license spectrum range and actually he buys the network from the service provider. The point of study is when frequency is getting jammed or out of coverage due to this the local user will unable to communicate in primary network as fact. On contradictory he has another network which can easily serve him. Looking to this a white-fi network which is design for small private network a Femtocell is designed. This network is temporary replacement of the primary one where the local user is comes in set of big primary network and under it can also falls in secondary network. The white-fi network is working on the dynamic frequency scanning, where a base station is small cognitive network to find free channels out of available for to resist the co-channel interference and the overlapping could be minimized. The detection of the signal in all noise channels is done through the passive and active channel scanning, along with the hybrid scanning technique min-max algorithms and feature detection. The identified channel is deployed only for secondary network node where the same user will communicated where primary network is not serving. Since use of available frequency is part of network and from which only 1,6,11 channel are rigorously being utilized due to normal scanning, all other channel mostly channel which are remains empty like 14 no. can be utilized for such a user who can communicate with its same device. The part of implementation of this work is scanning of ISM band spectrum channel 2.4 to 2.484 GHz where FAP (Femtocell access point) is Linux base station where the active scanning uses as OSA and DSA method. Use of MIMO Signalling scheme for DTE section is implemented.
