我们考虑两种增加开放接入频谱以提高无线服务市场竞争的情形：使新频谱可供无授权使用，或者要求现有许可证持有者与二级供应商共享频谱。我们的主要结论是，共享频谱时的社会福利和消费者福利总是大于无授权接入时的情况。而且当频谱数量足够大时，主要服务提供商通过共享获得的利润比无授权接入时更多。
We consider two scenarios for adding open access spectrum to increase competition in a wireless service market: making new spectrum available for unlicensed use or requiring an incumbent license holder to share it with secondary providers. Our main result is that social welfare and consumer welfare with shared spectrum are always greater than with unlicensed access. Also when the amount of spectrum is large enough, the primary service provider gains more profit with sharing than with unlicensed access.
