MB5G — *the network beneath the phone*.

Most of the writing about mobile networks reads like a press release or a spec sheet. There is a different conversation worth having: about the towers, the spectrum auctions, the protocol decisions, and the people who quietly make decades-long bets on the infrastructure we take for granted.

This is a small, considered publication for that conversation. Long sentences when they earn it; short ones when they don't. Always one writer behind the words.

Operating policy — Every frequency is logged with band, RSSI, latency, and jitter on the day it was tested. Carrier and antenna are reported as measured.

A WEEKLY TRACE

New allocations, RSSI snapshots, and the bands worth re-tuning.

Sent every Friday after the spectrum sweep. Peak signals across Sub-6 / Mid-band / mmWave, latency and jitter notes, and the carriers locking the band.

One trace a week. Drop the band any time.
