The telecommunications industry within the sector of information and communication technology is made up all Telecommunications/telephone companies internet service providers plays crucial role in evolution mobile communications society. main objective study to make a comparative among satisfaction level Airtel Jio customers. focuses on identifying different factors influencing major finding th...

Aloha-type random-access protocols have been employed as access-control protocols in wireline and wireless, and stationary and mobile, multiple-access communications networks. They are frequently employed by the control and signaling subsystem of demand-assigned multiple-access protocols for regulating the sharing of a multiaccess communications channel. The correct design and sizing of the ran...

One of the important issues in many of array systems such as Radar, Sonar, Mobile, and satellite telecommunications is the estimation of DOA of narrowband received signal. CRB is very important in evaluation of parameter estimation. CRB is the lower bound estimation error variance for any unbiased estimation. In this paper, the array antenna with equal distance arrays is extended in two separat...

The development of communications and telecommunications infrastructure, followed by the extension of a new generation of smart distribution grids, has brought real-time control of distribution systems to electrical industry professionals’ attention. Also, the increasing use of distributed generation (DG) resources and the need for participation in the system voltage control, which is possible ...

Based on the first comprehensive mapping of telecommunications provisions in regional trade agreements (RTAs), this paper shows that RTAs have evolved and expanded significantly over years. While some focus information communications technologies (ICT) infrastructure, policy investment, other address services as well standards conformity assessment procedures ICT equipment. The most detailed ar...

Through the lens of a outsourced global telecommunications network transformation project we examine how informal and ad-hoc communications led to misinterpretation of project objectives causing confusion, resistance, and a lack of cooperation between the Clients and the Outsourcing Provider producing project delays. We explore how the implementation of a Stakeholder Analysis served to resolve ...

Many security mechanisms for mobile communications have been introduced in the literature. Among these mechanisms, a simple authentication technique for use in the global mobility network (GLOMONET) is proposed. Specifically, the wireless medium introduces new opportunities for eavesdropping of wireless data communications. Anyone with the appropriate wireless receiver can eavesdrop and this ki...

The main aim with this paper is not to present hard results and requirements, but to propose a new area of research for joint efforts in WWRF. Work is ongoing throughout the world in the area of communications between vehicles and between vehicles and the road infrastructure. We strongly believe that a completely self-organized wireless communication network connecting all road-users would have...

Assisting during emergencies is one of the important functions of the telephone system. Emergency communications has three components: summoning help during emergencies, coordinating emergency response and notifying citizens and public officials of local emergencies. As we transition to an Internet-based telecommunications system, these functions need to be provided, but there is also an opport...

Relative to RF, the lower power-consumption and lower mass of high bandwidth optical telecommunications make this technology extremely attractive for returning data from future NASNJPL deep space probes. JPL is building an R&D optical communications telescope laboratory (OCTL) at the Table Mountain facility in Southern California. The telescope, scheduled for delivery in spring 2003, will among...
