Bangladeshi operator GrameenPhone has awarded a new radio equipment supply contract to NEC Corporation to expand and modernise GrameenPhone’s existing network.
Under this contract, NEC will deploy higher modulation (4096QAM), carrier aggregation (CA), MIMO systems and traffic aggregation functions across various layers and frequency bands (microwave and millimetre bands). These technologies will help GrameenPhone to reduce total cost of ownership (TCO) and to provide more reliable networks with higher transmission capacity.
