14.1.14 GPR MRU – Maximum Receive Unit
14.1.14.1 Overview
Configures maximum receive unit for the GPRS interface.
14.1.14.2 Usage
Attribute Type: Read/Write
The maximum receive unit is a part of the configuration that determines largest
data packet that can be sent over the GPRS interface before defragmentation is
required. In certain cases this can be used to optimize communications interface
speeds.
Providing value zero normally works, but some networks might require some
tweaking.
Recommended values for the various communication types are
GPRS over GSM/GMSK: 576
GPRS over GSM/EDGE: 1476
GPRS over UMTS/WCDMA: 1500
Format on getting parameter:
<MRU>
where <MRU> is the maximum receive unit, <MRU> >= 0.
