Bluwan
LinkFusion is a 42 GHz Millimetre Wave (mmW) Point-to-Multipoint multi-gigabit capacity backhaul system designed for HetNet backhaul.
LinkFusion delivers up to 10 Gbps on a standard 4 sector point to multipoint configuration, using 42 GHz spectrum.
The LinkFusion architecture allows operators to deploy either in Point to Point mode or Point to Multipoint Mode. Bluwan has a 1 GHz wide radio unit operating in 3 sub-bands. Each radio can actually transport up to 20 channels. Each channel delivers up to 125 Mbps, hence it can scale up to 2.5 Gbps on a single ODU. The standard IDU is an 8 channel IDU that can deliver 1 Gbps. Each IDU is stackable so that operators can provide more capacity without replacing the outdoor kit.
PTP Peak Performance:
In this instance, a single channel is dedicated to the end terminal in the same manner as a traditional PTP 1+0 connections and delivers 125Mbps of capacity. The difference being that LinkFusion can share up to 20 x 40 MHz channels into a single aggregation radio and therefore offers a total capacity of 2.5 Gbps.
PTP Peak Performance should be selected when bandwidth requirements to the site are high, typically for a larger base station.
PMP Shared Performance:
Bluwan also provides another mode called “PMP Shared Performance”: it allows up to 4 LinkFusion remote terminals, or NTEs to share a single channel.
In this method, the single channel can be shared between up to 4 terminals, each receiving a guaranteed capacity of 30Mbps. Therefore, it is possible to serve 80 terminals with a CIR of 30 Mbps of guaranteed capacity using the same 20 x 40MHz channels all terminating on a single sector outdoor unit. A single IDU, with 400 MHz of spectrum, would be able to hit 32 terminals with 30Mbps of guaranteed capacity.
IDU’s can be stacked to increase spectrum usage to consume the entire bandwidth of the radio (1 GHz).
