3.5. XBee-PRO 900 vs XBee-PRO 900HP
The new XBee 900HP modules support some changes:
•
The new XBee-PRO 900HP uses greater power transmission compared to the old version. Thus, the ranges
achieved by these new modules are larger than before.
•
The XBee-PRO 900HP modules are certified for use in multiple countries: Brazil, Australia, US. Through the
new channel selection it is possible to enable/disable the preferred frequency channels within the 902-928
MHz band.
•
The power consumption has been improved compared to the old modules. Better ranges have been achieved
with almost the same TX power. On the other hand, RX power consumption has been reduced.

3.6. 3G (SIM5215) vs 4G (LE910)
The new 4G module module supports some changes:
•
The new 4G counts with many different models, one specifically designed for each market:
-
LE910-EU (Europe / Brazil): CE, GCF, ANATEL
-
LE910-NAG (US / Canada): FCC, IC, PTCRB, AT&T Approved
-
LE910-AU V2 (Australia): RCM, Telstra Approved
•
The GPS module also makes possible perform geolocation services using NMEA sentences offering information
such as latitude, longitude, altitude and speed what makes it perfect to perform tracking applications.
•
The new 4G module offers the maximum performance of the 4G network as it uses two different antennas
( diversity) for RX (MIMO DL 2x2) choosing the best received signal at any time and getting a maximum
download speed of 100 Mbps.
