You may had seen a 4G LTE Modem which support 4G Band 4(1700/2100MHz) or 4G LTE Surfstick which is for 4G FDD Band 7 (2600MHz), but do you know any 4G USB modem that could support them together?
Today, we will recommend a 4G Aircard which could support the 4G LTE FDD Band 4 and Band 7 simultaneously. The model number is Rogers AirCard 330u LTE Rocket Stick. This is the successor of Sierra Wireless AirCard 320u. They are both from Sierra Wireless. The difference between them is that Aircard 330U is capable of LTE FDD Band 7 and Band 4, but AirCard 320U could support band 3 and band 7.
The Rogers LTE AirCard 330u looks cool in red color, but it's unlocked to Rogers network. It means the AirCard 330u could support any operators' SIM card. Just like the brother model AirCard 320u, 330u is in square shape and it's bigger than AirCard 306 or 308. The USB could rotate for 180 degree. On the front, There is logo of Rogers and one the back, there is printer of "4G LTE" on it. Below the "4G LTE", we can see the icon of the manufacturer "Sierra Wireless" logo, and the indicator of data transmission.
Open the back cover, we could see there is a stick indicating the model number "AirCard 330u" and the IMEI number of the 330u. Belie the stick, we can see the SIM card slot and MircroSD card slot. At the side of the SIM card slot, there are two external antenna connectors for MIMO. They are covered by two small cap, user need open the cap and then connect the external antenna.
The connector of the external antenna is TS-9 model, so if you want buy external antenna for AirCard, you could check here: http://www.4gltemall.com/external-antenna-for-huawei-4g-lte-usb-modem.html
the 4G Antenna is also usable for Aircard 320U and 313U.
After plug the two external antennas, the data link speed would improve obviously. The AirCard 330u is apt for North America 4G LTE networks band 13 and band 7, so it could also roam in Europe or Asia. In conclusion, AirCard is a cool USB modem that will be a good gadget for 4G networks.
