Although fiber-optic communication is used by a large number of telecommunication companies, satellite technology has still its important place among communication technologies. This article focuses on mobile antenna InetVu 1800+ Series. Besides detailed description of hardware and software components, functionality testing and troubleshooting of the whole system are included as the important parts of the topic.

In the current environment of burgeoning demand for mobile broadband, Long Term Evolution (LTE) is the most preferred wireless technology for the mobile operators. Considering the legacy multi-technology networks, operators need to strategically work upon maximizing their revenue while minimizing their cost and satisfying the subscriber's requirements as well. Operators have a choice between 2 network strategies- LTE overlay and single radio access network (SRAN). A survey carried out proved SRAN to be the optimum LTE deployment strategy considering the total cost of ownership (TCO). This paper discusses the effect on the system performance due to the up gradation of network from second generation (2G) to third generation (3G) to long term evolution (LTE) systems using Nokia Siemens Network Flexi multi-radio base stations. Measurements of RSRP (Reference Signal Received Power), SINR (Signal to Interference plus Noise Ratio) and throughput were carried out by a drive test within 2Km of the deployed site area which indicated that all the 3 parameters were affected as the user equipment moved away from the site area and towards the cell edges. This problem can be addressed by deployment of low power relay nodes, one of the promising techniques, for increasing the coverage of LTE advanced networks (the future of LTE systems).

Computation process has changed itself from desktop computing to cluster computing and to grid computing and now a days it goes towards cloud computing. In today's trend, Cloud computing is being preferred by majority of the organization because of its major advantages in terms of scalability and multi tenancy. Among all these advantageous features of cloud computing, the only hitch is the security of the data that is stored in the cloud. The security clause rests with the cloud service provider but security can be applied on client side also and it is possible if the user knows how his data is secured. This paper proposes a mechanism which can help the user to ensure the security of his data at the client-side.

In this paper, we have investigated the performance of IEEE 802.15.3a channel model with different modulation scheme. The performance parameter Average Bit Error Rate (ABER) is selected. We find out the BER performance of UWB system over the 802.15.3a indoor channel model for all channels profile CM1, CM2, CM3 and CM4 with different modulation scheme. In this paper, all modulation scheme used in UWB are included in different main categories. The major categories are synchronous and asynchronous. In synchronous mode, we again divided different modulation scheme e.g. BPSK, PPM, PAM etc into antipodal and orthogonal schemes. In the asynchronous category, we have studied about DPSK. All these modulation categories are comparing on the common platform and finally we got antipodal modulation scheme category is good for UWB in term of ABER.
