The Model 4520 Zoom We3G integrates a wireless router and 3G HSPA modem into a highly-portable product small enough to fit into a pocket, purse, briefcase, car console, or almost anywhere. Measuring only 3.75" X 2" X .6" and weighing less than 3 ounces, the 4520 is smaller and lighter than most mobile phones. The 4520 connects and shares the embedded 3G modem connection with up to five WiFi-compatible computers, phones, iPads, iPod touch, cameras, game stations or other devices. The wireless router provides 802.11 b/g connections at a range of 30 feet with WPS/WEP/WPA/WPA2 security. The embedded HSPA cellular modem operates at speeds up to 7.2 Mbps. The modem is unlocked and activated by inserting a standard SIM card for data service from AT&T or most other GSM-based cellular carriers worldwide. The Lithium-polymer battery provides up to four hours of active operation with a full charge and is rechargeable from either the AC adapter included or a powered USB port. A Micro SD slot accommodates up to 32 GB of memory and allows the 4520 to double as portable storage. The 4520 pocket gateway's modem supports GSM/GPRS/EDGE at 850/900/1800/1900 MHz and UMTS/HSPA at 850/1900/2100MHz.
