TCP-based web traffic performs poorly on mesh networks because each wireless hop halves effective bandwidth (bidirectional ACKs share the same half-duplex channel) and introduces highly variable latency and loss; voice traffic is similarly unsuitable due to jitter. Applications leveraging delay-tolerant networking principles or requiring only very low bandwidth are identified as the category of workloads that can function within mesh constraints.

Purpose-built or uncommon radio hardware provides governments a legal pretext for crackdowns, is subject to import restrictions, and aids identification of dissidents via radio direction-finding equipment. The authors conclude that only ubiquitous, innocuous devices—smartphones and standard indoor WiFi access points—can be used in a dissent network without raising suspicion or endangering users.

Gupta and Kumar proved that the per-node capacity of a multihop wireless network approaches zero as the number of nodes increases; Li et al. experimentally validated this result for 802.11-based mesh networks. The authors emphasize this is an architectural constraint derived from fundamental radio physics, holding for arbitrary networks regardless of routing protocol.

§4.1 evaluation

Mesh networks can reach meaningful scale only by adopting centralized management, planned growth, and a static topology—properties that simultaneously create a single point of failure and make nodes easy targets for government radio direction-finding. Decentralized, organic, mobile mesh retains safety properties but at the cost of near-zero effective capacity as network size grows.

§4, §7 defense

Pseudonymity is insufficient for dissent networks: social-network profile information can be correlated with external data to deanonymize users, and fixed-infrastructure networks enable localization attacks even without explicit identity. The authors argue that true anonymity—or at minimum strong deniability where usage is non-incriminating and activity is difficult to trace—is required to protect participants.
