Page 17: Redmax Base Station Overview
Each subscriber registers and establishes a bi-directional data link with the base station sector controller. The RedMAX base station is (part of) the 802.16 definition of a base station. A RedMAX base station base station functions as a central hub or concentrator, connected to a WAN network access point, and managing wireless links for remote subscribers.
Page 18: Ieee 802.16 / Wimax Compliance
- ProfP3_7: WirelessMAN-OFDM PHY profile for 7 MHz channelization (Rel. 1.1) Note that the 802.16 standards are subject to amendment, and RedMAX product design compliance applies to a specific revision of the standard. The RedMAX product does not support mesh communication (direct subscriber-to-subscriber).
Page 19: Time Division Duplexing (Tdd)
™ Base Station RedMAX user manual 2.5.2 Time Division Duplexing (TDD) The base station system uses time division duplexing (TDD) to transmit and receive on the same RF channel, or using separate RF channels using half-duplex FDD (HD-FDD). These are both non-contention based methods for providing an efficient and predictable two-way PTP or PMP cell deployment.
Page 20: Time Synchronization
2.6.3 Non Line-of-Sight The RedMAX system supports line-of-sight (LOS), optical line-of-sight (OLOS), and non line-of-sight (NLOS) operation. A clear LOS link has no obstacles within 60% of the first Fresnel zone of the direct path. An OLOS link has obstructions within 60% of the first Fresnel zone, but a visible path exists between the base station and subscriber.
Page 21: Channelization
™ Base Station RedMAX user manual Figure 4: System - Fresnel Zone A wireless link is considered non LOS if natural or man-made structures block the visible path between the base station and the subscriber. In this case, a wireless link can be established only if a reflective path can be established between the base station and subscriber.
Page 22: Service Flows
™ Base Station RedMAX user manual Service Flows Service flows are a key feature of the 802.16 standard. A service flow represents a unidirectional data flow. Transmitting bidirectional traffic requires that two service flows be defined: one for the uplink, and another for the downlink.
Page 23: Scheduling
™ Base Station RedMAX user manual 2.7.4 Scheduling The base station enforces QoS settings for each service flow by controlling all uplink and downlink traffic scheduling. This provides non-contention based traffic model with predictable transmission characteristics. By analyzing the total of requests of all subscribers, the base station ensures that uplink and downlink traffic conforms with the current service level agreements (SLAs).
