More and more operators are deploying HSPA+ netqorks, even though 4G LTE is becoming the mainstream of network upgrade. Based on dual-cell technology, DC-HSPA+ network is the upgraded 3G, or more accurately 3.5G network, which can make the data rate transmission reach up to 42Mbps. This speed is double to the link speed of HSPA+ network. Following the network upgrade, there must be new devices, such as USB Modem, wireless router, to support these networks.
As we can see, there are already many wireless modems or routers available in the market, but more and more wireless terminals are available with upgrade technology for data connection and stable performance. Huawei is the dominated vendor of wireless equipment and today, we would like to introduce a new Dual cell 42Mbps USB Modem - HUAWEI E3251.
HUAWEI E3251 was released long time ago, but recently it is available. Like its predecessor, Huawei E3251 is also in compact design, the body cover is in plastic, but it feels good. If you have touched the iPhone 5C, the feel is the same. The mancraftship of HUAWEI is now very mature. On the face, there is HUAWEI logo and LED indicator.And the back shows the Hilink logo. The design looks like Huawei E3131, but there are difference. The end of the E3251 is ascending， which makes users easier to remove the USB cap or from PC.
The demo we get is HUAWEI E3251s-6, no external antenna connector is available in this model. HUAWEI E372 has the external antenna connector (TS-9 socket). The main difference between the two models is that the E3251 is driverless, no installation and setup is needed. It's a real plug & play USB stick.
Unlike the HUAWEI E372, E3251 is managed by web UI, not HUAWEI mobile partner. That's the key features and improvement of E3251. Per the information of HUAWEI, E3251 has variant models, such as E3251s-1, E3251s-2 and E3251s-6. The 3G UMTS/HSPA+ bands they support is as below:
* HUAWEI E3251s-1
-- DC-HSPA+/HSPA+/UMTS 2100 MHz
-- EDGE/GPRS/GSM 850/900/1800/1900 MHz
* HUAWEI E3251s-2
-- DC-HSPA+/HSPA+/UMTS 2100/900MHz
-- EDGE/GPRS/GSM 850/900/1800/1900 MHz
* HUAWEI E3251s-6
-- DC-HSPA+/HSPA+/UMTS 2100/1900/850MHz
-- EDGE/GPRS/GSM 850/900/1800/1900 MHz
