Website www.icra.in The Indian telecom industry has witnessed significant growth in subscriber base over the last decade, with increasing network coverage and a competition-induced decline in tariffs playing facilitators. The growth story and the potential have also served to attract newer players in the industry, with the result that the intensity of competition has kept increasing, forcing th...
In current market scenarios, telecom companies are quite competitive and look forward to have lion’s share in the market by winning new and withholding existing customers. Customers who are lost to competitor are known as Churned customers and can be retain by adopting Churn prevention model. For a given dataset, this model predicts the list of customers to be churned in future enabling the res...
High-bit-rate nanocavity-based single photon sources in the 1,550-nm telecom band are challenges facing the development of fibre-based long-haul quantum communication networks. Here we report a very fast single photon source in the 1,550-nm telecom band, which is achieved by a large Purcell enhancement that results from the coupling of a single InAs quantum dot and an InP photonic crystal nanoc...
1. THE PHENOMENON Our work on adding the “missing user” to the telecommunication (telecom) policy discourse reaches back to the early 1990s.(1) Much like today, policy debates at the time raged over issues such as the upgrading of telecom networks and the need for new services, the (re)definition of universal service, the emergence of “information age” inequalities (e.g., the rural-urban divide...
Can airline Yield Management strategies be used to generate additional revenue from spare capacity in telecom networks? Pundits believe “yes”, based on several analogies between the industries such as, for instance, perishable inventory and negligible marginal cost of usage. However, no one has yet described how, one of the chief difficulties being the vastly different nature of airlines produc...
This report shows the technical realisation of the 7 Telecom I+D in Barcelona. Telecom I+D is the main Spanish conference on telecommunications. This year, the Telecom I+D conference took place simultaneously in the Telecommunications Engineering Schools of six Spanish cities: Madrid, Barcelona, Valencia, Bilbao, Sevilla and Pamplona. Tutorials and presentations were given from Madrid and Barce...
In order to promote the core competitive power for telecom operating enterprises to face market fine operation, this article compares the ECTA mode (Extension Case Transmission Mode) and the LCA mode (Loosen Couple Mode), both of which are promoted by WfMC. By comparing these two modes, the suitable situations for these two modes are determined. We also carry out empirical analysis based on the...
We define an inversion statistic on standard Young tableaux. We prove that this statistic has the same distribution over SY T (λ) as the major index statistic by exhibiting a bijection on SY T (λ) in the spirit of the Foata map on permutations.
