GL-MiFi Technical Specification

GL-MiFi technical specification
1/11
1Product description
GL-MiFi is a standard wireless MiFi which is apply to IEEE802.11b, IEEE802.11g,
IEEE802.11n and which is up to 150Mbps wireless transmission rate. It is powered by
Atheros 9331 processor. Therefore, the consumption power is lower, the
performance and stability higher than normal MiFi products.
GL-MiFi apply to industrial 3G/4G mini PCI-E interface and 3G/4G module, thus
ensuring its stability and flexibility. And it is equipped with a 5000mAh lithium
polymer battery pack, which can power the MiFi and power the mobile terminal.
Onboard dual power supply, fully guarantee the stability of the product work, but
also can make the product work without the battery.
