Could spectrum refarming solve global LTE roaming issues?

LTE network technology could be deployed across a vast range of spectrum bands in various markets across the world--a situation that could significantly hamper seamless roaming across those markets. However, according to speakers who attended the LTE Forum conference last week in Stockholm, global LTE roaming could be solved by refarming existing spectrum bands and using them for LTE service. One prime candidate that has emerged as a common band for roaming is the 1.8 GHz MHz band, which many GSM carriers use for voice. There are few bands below 1 GHz that are widely used around the world, and 1.8 GHZ could be a compromise between operators looking for propagation and those that want faster data speeds. Article
