Accès sans fil à large bande
In the Broadband Wireless Access Licence, “Broadband” means high-speed wireless connectivity which allows users to access services at an upload minimum rate of 256kbps with an upload-download ratio of 1:4 (upload rate of 256kbps corresponds to download speed of 1024kbps) The Licensee is required to develop and operate a broadband network to provide nationwide Broadband Wireless Access services.
LTE is one of the primary broadband technologies based on Orthogonal Frequency-Division Multiplexing (OFDM), which has currently been commercialized. In 2005, LTE and System Architecture Evolution (SAE) study items were set up in 3GPP. Both Operators and Manufacturers were keen to push these study items because they were facing competition from other technologies such as WiMAX . Operators were looking for significant improvements compared to UMTS releases that provided an architecture that was better suited to the shift from circuit-switched communications toward packet data and a radio technology that enabled spectrum re-farming. LTE Rel-8 provides high peak data rates of 150 Mbps (2x2 MIMO) on the downlink and 75 Mbps on the uplink for a 20-MHz bandwidth and allows flexible bandwidth operation from 1.4MHz up to 20MHz. LTE Rel-8, which is mainly deployed in a macro micro cell layout, provides improved system capacity and coverage, high peak data rates, low latency, reduced operating costs, multi-antenna support, flexible bandwidth operation, and seamless integration with existing systems. The LTE network architecture is designed to support packet-switched traffic with seamless mobility, QoS, and minimal latency . The first LTE network in Ghana was launched by Surfline Communications Limited in 2014. Download Operator Licence Information
