Testing the $700 CSL CS203 Integrated RFID Reader

Convergence Systems Limited claims their CS203 integrated UHF reader and antenna is an all-weather reader with IP68 rating for outdoor operations. They even say it’s passed Mil Standard 810 testing. But what’s most surprising is the CS203 has a suggested manufacturer’s retail price of only $700.00, making it the lowest cost UHF reader on the market. In this edition we’re going to put the CS203 to the test and see just how well the lowest cost UHF reader really performs.

The CS203 is an EPCglobal UHF Class 1 Gen 2 and ISO 18000-6C integrated UHF reader and antenna from Convergence Systems Limited. Recently upgraded, this unit is IP68 rated for indoor or outdoor applications and has a Mil Standard 810 rating for shock and vibration. Designed with versatility in mind the CS203 reader can be used in a variety of environment including warehouse, parking lot gate, livestock farm, or any location where asset visibility is essential. At only $700.00 this is the lowest UHF reader on the market.

We put the CS203 through a variety of tests. The first such test involved 25 different takes utilizing a van moving at various speeds with a series of tags in the windshield. The van passed under a CS203 reader mounted 5.2 meters above the ground. The reader read all 5 tags without fail.

The next series of tests involved two different CS203 units and a variety of passive – RFID labels, metal mount, and battery-assisted – tags. Overall, the results were good with the reader showing a very respectable read range, especially given the unit’s low price point.

Features of the CS203 Integrated RFID Reader & Antenna

• ISO 180000-6C Compliant
• IP68 rated for dust and water
• 810 Mil Standard rating for shock and vibration
• Connects via Power over Ethernet (POE)
• Available with either a left or right hand circular polarized antenna
• Read Zone Control

CS203 RFID Integrated Reader/Antenna Benchmark Testing

Our team performed benchmark testing using a variety of commercially available tags affixed to cardboard and metal.

RFID Read Performance Miscellaneous

Using the CS6820-2 CSL on a person and the CS6710 CSL on our van’s windshield as it drove by the reader at various speeds our team found the CS203 does have a fairly comparable read distance to other fixed readers.

RFID Read Performance on Cardboard

For our RFID tag performance benchmarks on cardboard, we used several recently released tags which we have not tested before. We utilized the UPM Raflatac DogBone, AD-826 and the PowerID PowerG tags. As you can see below the PowerID PowerG achieved and amazing 56ft of read distance with the CS203.

RFID Read Performance on Metal

Using our best performing tags as a baseline, the Omni-ID Prox™, Omni-ID Max™, the Omni-ID Max Pro™ and the latest PowerID PowerM, our team found the CS203 could achieve read distances of up to 62ft.
