Femto

Femto overview

3G era has arrived, all sorts of high-speed wireless applications are continually changing human way of life. As wireless bandwidth rising, mass grab information model happening fundamental change, anywhere, anytime, communication is possible, 3G hand-held terminals dozen causes information intersection of the stage. 3G communication gives information age characteristics of this large data business, it will produce Internet business effective extends to the mobile telecommunication field, according to the Japanese NTTDoCoMo survey results, 70% of 3G business happening in indoor environment. Similarly, aiming at north mobile phone use scene investigation data also showed, as the business development and user's spending habits improving, nearly 30% of the business use occurred in family area, and nearly 35 percent of business use occurred in the company, restaurants etc indoor environment. So indoor wireless coverage of the user's business is critical to use perception, and how to effectively improve 3G networks of indoor coverage, is 3G business success deployment of the key. However 3G network adopted by 2.1 GHz transmission loss and frequency resource, space of buildings wall is larger, the loss of the penetration ability very weak, operators have the biggest problems facing is indoor coverage quality often unsatisfactory. At the same time as large data business bearing area, how to effectively integrate fixed mobile broadband access, and in all the resources are operators in business operations facing tough questions.

Femto advantage

Enhance the network to the user viscosity. Fusion type Femto will move, fixed, broadband business fuses in together, the user through a Femto can achieve all of its telecommunication demand, and enjoy the business in different access mode of fusion roaming, greatly increases the user viscosity, help operators consolidate and develop home users user scale. Saving investment. Femto by fixed broadband access as its return, no hail selection and construction maintenance of the input, and greatly reduce operators in network construction investment. In addition, femto deployment is alleviated macro cellular network business load. Smooth evolution. Due to femto adopts flating architecture, accord with mobile network evolution trends such as LTE/EPS, Flat structure due to reduced node number, also conforms to all the IP network of real-time business to delay the strict request.
