Mimosa Networks provides wireless networking solutions as an alternative to laying fibre optic cables. Their fixed wireless technology uses directional antennas and advanced signal processing to deliver fibre-like speeds wirelessly over distances of up to 1 km. This allows internet providers to cost-effectively connect more homes and businesses to high-speed networks without having to trench for fibre. Mimosa has deployed commercial networks delivering speeds up to 1 Gbps to thousands of customers. Their solutions use technologies like massive MIMO and adaptive beamforming to maximize capacity and coverage of 5G and emerging WiFi standards.

11. 5G Now Means Fixed Wireless
Connecting consumers and businesses to a fiber
network is expensive, and that it's possible to
reduce that cost by getting a fiber connection
within 1,000 meters of a building and then
connecting that building to the fiber network
wirelessly via a 5G router on the outside of the
building.
“Half of our cost to establish high-speed data, whether that's consumer or business, is
inside the four walls of the business. Once you go wireless, you don't have to run
coax, you don't have to do any of those high-labor-intensive activities. So you light up
service overnight.” - Lowell McAdam, CEO

23. ¡ Wi-Fi radios have very good receive sensitivity
¡ kTB + NF = k * 300 K * 20 MHz + 3 dB = -98 dBm
¡ aka: thermal noise + radio noise = receiver sensitivity
¡ Packet detection based on energy threshold + auto-correlation
¡ Constantly trying to decode packet with faint energy in the air
¡ Dominant source of packet error rate
¡ Short range fixed access Rx signals are very stable, high SNR
¡ Intentionally reduce receive sensitivity (non-intuitive!)
¡ Real-time AGC training algorithm, per packet gain adjustment
¡ Shrinks receive footprint, avoid low power/far away interference
¡ Recover otherwise unusable spectrum, especially in high SNR
