196 | Uplink Configuration Dell PowerConnect W-Series Instant Access Point 6.2.0.0-3.2.0.0 | User GuideFigure 141 - Uplink Status3G/4G UplinkW-Instant supports the use of 3G/4G USB modems to provide Internet backhaul to an W-Instantnetwork. The 3G/4G USB modems extend client connectivity to places where an Ethernet uplinkis not feasible. This enables the IAP3WN to choose the available network in an area automatically.NOTE: The 3G and 4G LTE USB modems can be provisioned on IAP3WN and W-IAP108/109.Types of ModemsW-Instant supports the following three types of 3G modems:l True Auto Detect— Modems of this type can be used only in one country and for a specificISP. The parameters are configured automatically and hence no configuration is necessary(Plug and Play).l Auto-detect + ISP/country— Modems of this type require the user to specify the Countryand ISP. The same modem is used for different ISPs with different parameters configured foreach of them.l No Auto-detect—Modems of this type are used where the modems share the same Device-ID,Country, and ISP, but need to configure different parameters for each of them. These modemswork with W-Instant provided the correct parameters are configured. All the new auto-detected modems falls under this category as the parameter necessary to automaticallyconfigure them are unknown.The following table lists the types of supported 3G modems:Modem Type Supported 3G ModemsTrue Auto Detectl USBConnect 881 (Sierra 881U)l Quicksilver (Globetrotter ICON 322)l UM100C (UTstarcom)l Icon 452l Aircard 250U (Sierra)l USB 598 (Sierra)Table 35 - List of Supported 3G Modems
