Alphabet Looks to Wirelessly Connect Homes to Internet

Google parent says [fixed wireless] technology is less expensive

than laying cables

“ “June 8, 2016

5G Now Means Fixed WirelessConnecting 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

¡ 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

Impacts to Cell Size

High immunity to lower powered nearby indoor Wi-Fi and planned self-interference
