• 150 Mbps - 1SS 2.4GHz 802.11n (40MHz chan.) = N150 class

Overview

• the Qualcomm MDM9615 Gobi baseband (on the iPhone wiki)
• SK hynix Flash/RAM chip (H9DA4GH2GJAM?, CR4EM is visible on the package)
• an Atheros (likely SDIO) 802.11 chip

The device appears to be single-stream and limited to HT20 modes (max rate of 65Mbps).

Per the FCC SAR report under the cellular bands,

• WiFi is not operated when connected to a computer’s USB port.
• WiFi is operated when connected to the USB port of the AC USB adapter.
• This is a USB Dongle. Therefore, there is no voice transmission.

Per the FCC manual, the default SSID pattern is presumed to be C Spire 4G LTE Hotspot XXXX for C Spire branded units (is this device sold by any other carriers?).

Moderate (52 entries as of 03/22/2013) WiGLE data for the SSID, F4:63:49 (Diffon Corporation) OUI, last 4 chars are from the BSSID (upper case hex characters)
