RT4 vs. RT3

[ RT4 Home ]

The Carlson RT4 is an enhanced version of the Carlson RT3.

These devices are based on the Juniper Systems Mesa 2 and Mesa 3 field computers:

RT3 = Mesa 2
RT4 = Mesa 3

In a nutshell, the RT4 has twice the memory, the memory is twice as fast, the disk is twice as big, the processor is twice as fast and the RT4 has better Bluetooth and Wi-Fi.

This results in a much faster field computer. Where the RT3 was slow to boot and update, the RT4 is a whole new experience and is ready for demanding field use.

The price of the RT4 Basic is approximately $350 less than the RT3 GEO (roughly comparable devices.)

The RT4 is compatible with Version 6.06 and higher only. Earlier versions of SurvPC will not work with the RT4.

Memory

Twice the memory (this is a big deal)!

RT4: 8 GB LPDDR4      RT3: 4 GB LPDDR3

DDR4 has 35% better power efficiency than DDR3.
DDR4 is about twice as fast.

Storage

Twice the storage (disk drive) space

RT4: 128 GB Flash Storage RT3: 64 GB Flash Storage

In addition to the built in storage (C:\) there is a microSDXC card slot that is optimized for 32 GB to 2 TB UHS-I, II, III, Express cards. (Samsung memory is recommended, however other brands also work.)

Processor

Essentially twice as fast, across the board.

Graphics speed is also greatly enhanced:

RT4: 18 execution units, Gen 9
RT3: 4 execution units, Gen 7

Communication

The RT4 adds 2x2 MIMO 5-GHz Wi-Fi.

Bluetooth is upped to 5.0 from 4.0 which offers: twice the speed, four times the range, lower power, larger message size and better IoT support.

The Cell Data Modem is 4G LTE, and designed for worldwide coverage. It has passed ATT and Verizon approval. It should work with other carriers that accept PTCRB approval (Rogers, Vodafone, O2, T-Mobile/T-Com, Sprint, Movistar, Telstra).

The Geo Cell model uses the Ublox M8N GNSS receiver, and does not have an external antenna port.

The base RT3 model is not available in the RT4 series. The RT4 Basic model is closest to the RT3 GEO model.
