Huawei Technologies Co., Ltd., the largest telecommunications vendor in China, today announced the global launch of the company's customized innovative UMTS Distributed NodeB Solution with enhanced features of reduced TCO (total cost of ownership) at the 3GSM World Congress 2005 in Cannes, France.

Huawei's UMTS Distributed NodeB Solution was developed to address customers' demands to build a quality 3G network quickly and economically. According to Huawei's internal research and analysis, the new UMTS Distributed NodeB Solution is able to effectively reduce TCO by more than 30% as well as speed up the completion of a 3G network construction. The new solution facilitates the deployment and optimization of network construction by minimizing the investment required in electricity, space resource and decreasing the occupation of labor.

Dutch Mobile Operator, Telfort, appointed Huawei to deliver and install a nation wide UMTS network in the Netherlands. Said Mr. Ton aan de Stegge, CEO of Telfort, "We are glad to have Huawei as a strategic partner in our developments of mobile data and UMTS. Huawei stands out in the industry with their innovative and competitive solutions and we are confident that they help us to deliver innovative and cost effective data solutions for our customers."

Huawei's new UMTS Distributed NodeB is a result of our profound understanding and prompt response to our customers. With the continuous capacity expansion in mobile network, site selection has turned into a bottleneck in the construction phase. 80% of a mobile network' s traffic volume comes from densely populated areas, making it increasingly difficult and more expensive regardless of whether operators share 2G sites or select new sites. Huawei's new, innovative UMTS solution aims to reduce difficulties associated with site acquisition and to cut down OPEX (operating expenses), by breaking the NodeB into two function units of RRU(Remote Radio Unit)and BBU (Base Band Unit) while still in accordance with the CPRI (Common Public Radio Interface) standard.

BBUs can be fixed in any standard cabinet due to its miniaturized design of 19 inches in width and 1U in height. With characteristics of a small footprint, easy installation, comprehensive functions and low power consumption, it is convenient for BBUs to coexist with existing sites and support capacity expansion through concatenation.

With similar features to the BBU, the RRU can also be easily and directly installed on the mast or walls near antennas. Compared with the traditional BTS (Base Transceiver Station), the unique structure of Distributed NodeB cuts down power consumption by more than 1/3 of the original usage.

There are various flexible application modes of Huawei's UMTS Distributed NodeB Solution.

Mode 1: Fully outdoor solution
BBUs can be placed in the GSM Macro Base Stations of any brand names or auxiliary equipment. RRUs can be placed on mast near the antenna which can be fixed together with the GSM system. This solution does not need additional rentals or sites, and delivers a fast and economical deployment of the 3G network.

Mode 2: Partially outdoor solution
BBUs can be installed along the aisle, stair way, basement or anywhere available; while RRUs can be installed on the mast or the top of the pole near the antenna. This solution can also be adopted when there is a lack of appropriate equipment rooms. This solution reduces the investment required for TMA (Tower Mounted Amplifier) and cables, and shortens the construction time while enhancing the capacity and the footprint of the 3G network.

Mode 3: Indoor site sharing solution
Macro Base Stations with large capacities can be placed in the central equipment room together with BBUs. BBUs can also be installed at other appropriate locations where there is an abundance of optical fiber resources. BBUs and RRUs are connected to each other through optical fiber which can be extended as far as 40 kilometers. With full use of original optical fiber, this solution cuts down the investment required for equipment rooms and auxiliary equipment and is most suited for mobile network constructions in large cities.
