Mobile networking devices such as 3G/4G dongles and MiFi devices are fast becoming hot commodities as our appetite for data consumption continues to grow. Depending on the device type, here are the two tests we commonly use to gauge their performance: • For devices capable of sending and receiving data packets such as a mobile router with a LAN port, we use our standard 1GB file transfer test at various ranges to see how stable and fast the connection is. • As for devices that rely on a mobile operator’s signal strength such as MiFi devices, we test them around the Klang Valley to provide you with a better picture of the service as a whole. For devices like these, we also rely on the Speedtest. net application or website to discover its Download, Upload and Ping rates.
