What Has Redline Changed In COTS To Meet The Utility Market Needs? 1.A Smart Grid network is fundamentally different than a Service Provider access network in that the bulk of traffic flows primarily from the edge of the network to the core of the network.  Service provider networks are built with a “downlink bias” where the majority of traffic flows from the core to the edge.  In a Smart Grid, the traffic is ‘uplink biased’ with a large number of distributed Smart Meters, IEDs, Video Cameras etc delivering information from the sensors and machines at the edge of the network up to data centers in the core of the network.  Redline’s design engineers have modified the core signal processing in both the base station and CPE to allow the uplink / downlink ratio bias desired by each utility’s network design architect. 2.Power Engineers have a requirement for sub-cycle latency in the two-way communications network.  Typical multipoint wireless broadband systems whether RF/WiFi mesh or cellular based have one way latency in the 35 – 150 millisecond range.  Redline’s engineers have modified the core signal processing within the base station and CPE terminals to reduce the one-way latency to under 20 milliseconds as required by the utility. 3.Long range connections are required for both smart meter collection and Teleprotection.  RedMAX 4C can be used effectively for backhauling rural smart meter and sub-station connections, enabling a more cost-effective deployment.  Redline’s products have the ability to support a longer range of up to 25 km versus the 9 – 10 km supported by the WiMAX Forum profile enabled by modifications to the e-2005 MAC in the BTS & CPE. 4.Smart Grid networks use IEC based protocols that are not necessarily IP based, layer 2 Ethernet transport is required.  Capability of forwarding the traffic at layer 2 rather than sending information to a centralized ASN-GW may also contribute to the reduction in end-to-end latency. 5.RedMAX 4C Remote Radio Head (RRH) implements Digital Pre-Distortion (DPD).  Advanced RF capability allows higher output power with reduced power consumption with the added benefit of reducing both adjacent and alternate channel interference enabling better spectrum utilization and tighter frequency reuse.
