Femtocells: Smart Approach Analysis to Macrocells

Resource Allocation in Cellular Networks with Coexisting Femtocells and Macrocells

Connection Cost Based Handover Decision for Offloading Macrocells by Femtocells

Femtocells can offload macrocells and reduce a cost of transmitted data in wireless networks. If a connection via the femtocell is of a lower cost than via the macrocell, a time spent by users connected to the femtocells should be maximized. This leads to a reduction of the overall cost of user’s connection. Besides, a prolongation of the time spent by users in the femtocells reduces load of th...

Reducing Unnecessary Handovers: Call Admission Control Mechanism for Handover between WiMAX Macrocells and Femtocells

Femtocells are capable of providing services in shadowed areas of the WiMAX macrocell (cell coverage enhancement) and can relieve traffic from the macrocell networks, reduce infrastructure costs for the network operators, allow for network capacity increase, and provide needed service quality in indoor environments. However, conventional handover methods cannot support a good enough performance...

non-corrective approach to pronunciation

the aim of this study has been to find answers for the following questions: 1. what is the effect of immediate correction on students pronunciation errors? 2. what would be the effect of teaching the more rgular patterns of english pronunciation? 3. is there any significant difference between the two methods of dealing with pronuciation errore, i. e., correction and the teaching of the regular ...

Introduction to Femtocells

Mobile phones have been one of the fastest-growing consumer technologies of all time. Digital mobile phones were introduced in the early 1990s, and have now grown to include around 4 billion mobile phone subscriptions worldwide – nearly 60% of the world’s population. The number is continuing to grow quickly, and is expected to reach 5.63 billion by 2013 (1). Mobile phone data traffic is forecas...
