What’s the Difference between Sierra 770s and 754s 4G Mobile Hotspot?

At the beginning of 2013, the US vendor Sierra Wireless released a new 4G LTE mobile Hotspot Sierra 770 Wireless Aircard. Actually, we feel puzzled why Sierra Wireless released the 770s. It’s not because there is already AirCard 770s, but there is another similar 4G AirCard from Sierra 754s. The model number is 754s. What makes us more curious is that the AirCard 770s and AirCard 754s are both for the provider AT&T, in our opinion, they are very similar, almost the same functions besides the appearance.  




Let’s have a review of the two 4G LTE Mobile Hotspot Sierra 770s and Sierra 754s. Hope to find something unknown.  




From the official specification, we found Sierra 770s Mobile Hotspot incorporates dual-chipset (Qualcomm MDM 9215 and WTR1605L) while Sierra 754s has only one chipset Qualcomm MDM 9200. In this case, Aircard 770s should have upgraded the chipset to have better performance.  


Network Band


They both work for LTE 700MHz (Band 17) / AWS (Band 4), which is the AT&T 4G LTE network spectrums. But there is some difference on 3G UMTS bands; the Sierra AirCard 770s could support HSPA/HSPA+ 850/1900 MHz while Sierra 754s supports UMTS/WCDMA 850/900/2100 MHz. On 2G network, Sierrra 770s works on GPRS/EDGE 850/1900 MHz while 754s works on Quad-Band GSM/GPRS/EDGE (850/900/1800/1900MHz). This should be the key difference between them. Because the 3G network band decides which model could be used.  




Other same specifications between them:  


* 2 x 2 MIMO antenna connector for LTE

* Wi-Fi 802.11b/g/n

* FDD-LTE Category 3

* Supports up to 10 Wi-Fi devices (configurable)

* 100 Mbps downlink, 50 Mbps uplink)

* MicroSD TM / SDHC support (up to 32 GB)

* Standalone and assisted GPS  


We suppose the Sierra Wireless Aircard 770s is for specific areas in US because the network coverage of AT&T may vary on spectrum of 3G UMTS and 2G GSM/GPRS. However, since no official saying is presented, we can’t make this conclusion.  




Sometimes, we believe the newer, the better, especially for consumer electronics. And from appearance, the Aircard 770s looks really cool in color and design. We believe it would never let the users disappointed. If you want to buy this new mobile hotpsot, welcome to land for more details.
