This is about 1.5 Gbps/square kilometre. Bluwan can increase this capacity further through increased sectorisation and in the future by using MIMO and next generation chipsets.
Using a PMP architecture allows operators to keep the quantity of equipment low, reduce install, alignment, rental, and maintenance costs, as well as accelerate the time to market for the delivery of services. Only one backhaul system is necessary for 3G, 4G, Wi-Fi, small cells and enterprise access.
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.
LinkFusion also allows operators to allocate a single channel per end point, in effect “dedicating” 125 Mbps TDD bandwidth to the terminal. If the end point capacity requirement is higher, LinkFusion can “bond” 2 channels together to deliver up to 250 Mbps per end point. This mode is called “PTP Peak Performance”.
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 (4G LTE, enterprise access, Multiple Dwelling Units, or triple play services).
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). Operators should use PMP Shared Performance when providing lower bandwidth to each remote terminal, such as for small cells, mass market triple play customers, or small medium businesses. Each channel can independently be configured in ‘Peak’ or ‘Shared’ mode using a software defined network layer, making the solution very flexible to dynamically manage different network usage scenarios.
