Draft - Subject to Change

Hydra is a totally novel UHF Passive RFID Reader solution designed to lower RFID implementation

and running costs while enabling the realization quality read zones. Hydra readers combine a full-

power 30dBm UHF reader, 8dBic antenna and a patent pending “Hydra” power and data router

technology.

• 30dBm EPC Gen 2 Class 1 UHF Passive RFID

Reader

• 8dBic Slimline Antenna

• Built-in Mulitple-PoE Switch to Network Readers

Together

• “Hydra” Power and Data Routing

• Low-Cost Reader Installation and Management

• Works seamlessly with the ALR-F800-X with

Emissary

ALR-F3700 “Hydra” Series

Interconnected Reader/Antenna Combination

with self-healing power and data networking

Feature Enabled By Beneﬁ t

Lowers Implementation

and Running Costs

• Low-cost read point with integrated antenna

• Simply connect PoE for data and power

• Just connect each reader to it’s nearest neighbor

minimizing long cable runs.

• Less up-font cost for capital equipment

• Smaller cable runs (less cable to purchase)

• Less cable means less installation costs

Extensible Solution -

grows or shrinks with

your RFID needs

• Each reader inputs and outputs both power and data via

Power-over-Ethernet (PoE) to the next reader.

• Low cost per read point

• Each reader contains an antenna

• A poor read zone is addresses by adding another

low cost read point and connecting it to its nearest

neighbor for both power and data.

• Allows all desired tags to be irradiated and

made visible to at least one read point.

• Bad read zones can be ﬁ xed by “daisy-

chaining” another low-cost read point

without breaking the Return-on-

Investment (ROI) model

• No long cable runs for added read points

Massively Simpliﬁ es

Network Connectivity

• PoE (power and data) in and out

• ALR-3720 supports two PoE ports for daisy chaining

• ALR-3733di supports 3 PoE ports for adding more

complex topologies for data/power robustness

• Simple, low cost installation

• Lowers infrastructure and cable costs

• Less to maintain

Designed to Work

Seamlessly with the ALR-

F800-X with Emissary

• Like all Alien readers, Hydra’s send a self-discovery

heart-beat over the network

• F800-X with Emissary manages a subnet of Hydra

readers directly

• License free Emissary manages the network

and describes the work-ﬂ ow of any alien reader

combination

• No need for a server to control a reader

network

• ALR-F800-X manages the Hydra network

conﬁ guration and work ﬂ ows...no

programming required.

Robustness

• Self healing network re-conﬁ guration on a cable failure

• ALR-3733di enables more complex network topologies

• Solution can be conﬁ gured to tolerate

certain network failures and automatically

reconﬁ gure both power and data (no

human intervention required)

• Warehouse

• Dock doors

• Work in Progress
