The need for affordable, high speed broadband services to rural areas of un(der)served nations is underlined by the United Nations and the ITU. Satellite service offerings are not yet viable for general consumers: monthly costs of satellite bandwidth and initial installed cost of user equipment are too high; outdoor units are too large ; and total available capacity and capacity density are too low and inflexible to form a significant component (eg 10-20%) of a national broadband infrastructure. Terrestrial technologies are also costly and impractical over very large sparsely populated areas and so isolated homes, businesses and communities are currently left disadvantaged. Methera is planned as a flexible constellation of MEO satellites to help fill the gap for partner nations who will be able to provide these services to small, low cost user terminals, at prices competitive with terrestrial technologies. Methera will be capable of providing 300- 1000Gbps capacity to each of 5-15 partner nations distributed around the globe. This study will allow the team to design and model the system and predict the distribution of capacity, cost and performance which can be delivered to meet the national rural broadband market needs of prospective participants which will hopefully lead to advanced sales.

联合国和国际电联强调，需要向未得到服务的国家的农村地区提供负担得起的高速宽带服务。卫星服务产品对一般消费者来说尚不可行：卫星带宽的月成本和用户设备的初始安装成本太高;室外单元太大;总可用容量和容量密度太低且不灵活，无法形成国家宽带基础设施的重要组成部分（例如10-20%）。地面技术在非常大的人口稀少地区也是昂贵和不切实际的，因此孤立的家庭、企业和社区目前处于不利地位。Methera计划作为一个灵活的中轨道卫星星座，帮助填补伙伴国家的差距，这些国家将能够以与地面技术竞争的价格向小型低成本用户终端提供这些服务。Methera将能够为分布在地球仪的5-15个伙伴国家提供300- 1000 Gbps的容量。这项研究将使该团队能够设计和建模系统，并预测可以提供的容量，成本和性能的分布，以满足潜在参与者的国家农村宽带市场需求，这将有望导致提前销售。
