WiMAX™ - HOME > Features & Concepts
Kyocera's regenerative repeater consists of a donor node and a service node.
The donor node serves as a WiMAX mobile station and the service node serves as a WiMAX base station. WiMAX signals received from the WiMAX BS are converted to base band signals and enhanced at the donor node. The digitized signal is transferred to the service node and re-converted to a WiMAX signal for communication with the WiMAX mobile station.
･ MIMO (Multiple Input and Multiple Output) supported for higher throughput
･ No deterioration of WiMAX performance
･ Stable data communication
･ Suppresses interference between donor node and service node (loop interference) by assigning separate spectrum bands
Kyocera also provides indoor WiMAX base stations, which use a unique technology incorporating repeaters. The driving concepts behind Kyocera's indoor base stations are compact, lightweight design and minimal engineering costs.
WiMAX operators often face difficulties in getting permission from building owners to deploy indoor base stations due to the equipment's size and the construction requirements for installation. Also, base station deployment usually involves high engineering costs, because typical indoor base stations require a GPS antenna on the roof. Such engineering costs greatly impact a WiMAX operator’s capital expenses (CAPEX).
Kyocera’s femto-based indoor solution, the Super Picocell Base Station, is compactly designed at 210(W)x44(H)x34.5(D)mm and weighs less than 800g. This compact, lightweight design is ideal for deployment anywhere indoors.
The Super Picocell Base Station contains a high-sensitivity GPS receiver which allows the GPS antenna to be installed indoors (near a window). Therefore the Super Picocell Base Station basically requires no alteration of existing floors or ceilings nor expensive lower loss cables — thus simplifying installation and easing negotiations with building owners. This feature also minimizes engineering costs during deployment.
WiMAX operators can easily deploy Kyocera's Super Picocell Base Stations to cover weak signal areas indoors.
