APPLICATIONS

E-band fronthaul driven by MIMO & small-cells

The E-band (71-76, 81-86 GHz) has been chosen by industry and regulators for mmW 5G infrastructure/outdoor connectivity, enabling:

 • Throughputs of 100 Gbps +

 • Latencies < 10 us

 • Massive IoT (1M / sq.km).

To make this possible MIMO arrays will form key building blocks of the next-gen. E-band fronthaul infrastructure: fibre in the air.

Enabling MIMO small-cells

fronthaul_v2_mid.png

Although E-band antenna sizes have decreased considerably (see: Mti WE E-band flat antenna), front-ends have not - as they still use waveguide diplexers (e.g. Eravant). Furthermore, costs have remained high (due to GaAs bare dies + waveguides) - a no go for small-cells and MIMO.

Our E-TRX-HP SoC front-end (1 x 1 cm) solves this problem - by replacing the waveguide diplexer with a planar one, as part of the IC package - enabling small-cells.

Our E-TRX-LP SoC front-end further reduces costs by replacing the GaAs dies with CMOS - for the first time enabling low-cost, high-volume MIMO.

Last-mile & fixed-wireless access

Last-mile & FWA links offer the benefits of fibre, without the need for laying cables in the ground - and are the first step to denser fronthaul and eventually small-cells.

To date, last-mile E-band deployment has been slow - hampered by the high front-end costs. Our E-TRX-HP SoC front-end will reduce link costs significantly.

Backhaul

For long-range & high-capacity links, Multifractal's E-TRX-HP provides the lowest TCO!


In fact, E-TRX-HP is so versatile it can be used for back-haul, mid-haul or fronthaul applications.
