Huawei and Grameenphone will Jointly Show Innovative VillaRadio Solution for Deep Coverage in High-Dense Residential Areas

[Spain, Barcelona, Feb 24, 2017] At MWC 2017, Huawei and Grameenphone, Telenor's subsidiary branch in Bangladesh, will jointly show an in-depth coverage innovative solution for use in high-dense residential areas.

Dubbed "VillaRadio", this solution is a radio network coverage solution that features centralized management and distributed deployment. The solution architecture consists of remote units, master units, and baseband processing units. Using optoelectronic composite cabling, this solution allows for data transmission and power supply over a single cable, simplifying project engineering and installation. VillaRadio supports a broad set of radio access technologies, from GSM to UMTS and LTE, and features high-integration and small-dimension products, making it possible for operators to deploy networks flexibly by using poles and walls in residential areas. Also, VillaRadio enables network devices to seamlessly blend into the surrounding environment. In terms of coverage capability, services can be provisioned for buildings up to 50 m high. Another eye-catching feature is BBU sharing with macro base stations, with which the existing resources can be used for network deployment to lower network construction cost.

GSM traffic in Bangladesh hovers persistently around a high level, making it necessary to innovate on how to improve the network coverage further. Bangladesh is no different than other developing economies, city like Dhaka has experienced enormous growth over the past years In many areas, building spacing is, on average terms, as narrow as two to five meters, making it difficult to rely on macro base stations for coverage improvement. On live networks, the distance between macro base stations is mostly below 300 m, ruling out the possibility of densifying base stations to improve the coverage. Besides, the coverage ratio of the traditional distributed antenna system, or DAS, is less than 1% in this country due to the high cost structure associated with this.

With easy blending with surroundings and support for BBU sharing, VillaRadio can be flexibly deployed in densely populated residential areas for immediate in-depth coverage improvement, helping address the concerns for challenging site acquisition and network coverage in the construction-diversified areas. With the VillaRadio solution successful trial, Grameenphone anticipate to achieve coverage upgrade in a number of residential areas, contributing a lot to improved coverage and throughput. Importantly, subscriber complaints are also likely to reduce and the strength of the operator brand to grow substantially.

VillaRadio supports a listing of flexible capacity technologies to improve spectral efficiency. The technologies include dynamic cell splitting, high-order modulation (256QAM), and carrier aggregation. Using these technologies, capacity expansion on live networks can be achieved through software upgrade, which allows operators to improve user experience while lowering operational costs. At the same time, this solution uses distributed architecture that can best suit network construction in residential areas while enabling smooth evolution to Cloud RAN. Through software upgrade and introduction of new NEs, VillaRadio even enables mid-term and long-term evolution to human-to-things and things-to-things networks, helping protect the investment and increase the competitiveness for operators.

VillaRadio solution also applies in small-depth buildings and building blocks that similar to areas, commonly like apartments, budget hotels, and office buildings. VillaRadio is completely compatible with LampSite, another innovative indoor solution of Huawei, in system architecture and supports BBU sharing with the LampSite, making it an ideal choice for operators to deliver superb user experience under various complicated building scenarios.

Grameenphone Head of Network Planning, Md. Munir Hasan, said that “the VillaRadio solution has been an innovative solution born out of necessity in high population density cities like Dhaka that requires multipronged solution approach. Grameenphone’s strength has been its wide, robust coverage and we have been able to keep our promise to our subscribers in the affected areas.”

"Good connection is a catalyst for economic development and social progress. Huawei stays committed to building a better fully-connected world and enriching life through communication across the entire world," remarked Ritchie Peng, President of Huawei Small Cell Product Line. "Residential areas are the most important to people's daily life. Huawei Small Cell will, as always, offer optimal network solutions for various complicated scenarios and endeavor to help customers succeed and promote the development of the MBB industry."

MWC 2017 will be held between February 27 and March 2 in Barcelona, Spain. Huawei will showcase products and solutions at booth 1J50 in Fira Gran Via Hall 1, booth 3130 in Hall 3, and the Innovation City zone in Hall 4. For more information, please visit
