This read-only value reports the GPRS QoS peak rate actually negotiated with the network, the real burst throughput ceiling granted to this connection. An admin monitors this to see whether the carrier granted the requested burst capacity or throttled it, which affects how well the link handles short traffic spikes. For example, if file-transfer bursts over the cellular link are being capped unexpectedly, checking this negotiated peak rate against the requested value can confirm the network is the source of the throttling.
