Nextel Brasil is set to double its 2015 CAPEX to USD1 billion as it extends its mobile network to around 200 new cities next year, on top of the 497 covered at present. In order to facilitate its goals, Alfonso de Orbegoso, vice president of legal and regulatory affairs, confirmed that Nextel has inked a five-year network sharing agreement with fellow mobile operator Vivo – a deal which is expected to be initiated before the end of the year. In addition, Orbegoso told Telesintese that Nextel is still interested in acquiring the vacated 1800MHz frequencies previously held by the now-defunct Unicel in Sao Paulo state.
