The Machine to Machine communication challenge

Many businesses critical applications such as Teller Machines (ATMs), Point of Sales (PoS),Vending machines, bar code scanners and check readers, rely on leased line communication services.

Although familiar and reliable, these services suffer from strong limitations in terms of provisioning and

maintenance, scalability, capacity and mobility. Even more, mission-critical services based on leased lines

constrain business expansion to areas with cable coverage.

Benefits of cellular services for Machine to Machine

communications

The global 2G/3G coverage, the cellular network stability and maturity, together with the speeds offered

by recent 3G implementations (HSDPA speeds up to 7.2 Mbps), make Wireless WAN technologies the best

candidate for the implementation of secure and reliable business critical M2M (Machine to Machine

communication) services worldwide in a simple and cost-effective way. With no need of land line cabled

infrastructure, 3G services deliver unrestricted mobility to mission-critical applications.

Teldat 2G & 3G routers for Serial/Dialup M2M communications

Teldat's leading transaction-oriented 2G & 3G cellular routers offer fast, secure and reliable

interconnectivity to business critical applications in temporal events, at remote locations or in permanent

locations where unrestricted ubiquity is a must. The seamless Teldat 2G & 3G router integration

with traditional mission-critical application infrastructure, and specifically for Machine to Machine

communications, has proven its success worldwide.

Teldat cellular 2G & 3G routers can transfer any type of serial or dial-up protocol - X.25, SNA, SDLC, etc -

over the IP cellular network in compliance with standards - XoT, DLSw, Modbus over TCP, etc - and at

speeds which were not possible to achieve with leased line services. The vast protocol and functionality

suite supplied by the business-graded Teldat Internetworking Software (CIT), not only guarantees the

interoperability and a carrier-class manageability, but it also supports VPN's - with hardware accelerated

data encryption -, QoS, advanced routing and many other features needed for an efficient performance of

business critical solutions.

The reliability in the 2G & 3G cellular Machine to Machine communications access is always guaranteed.

The 2G & 3G router's external antenna delivers the best signal performance at any location. Software-driven cellular failure detection techniques, together with the dual SIM support, provide a rapid

responsive failsafe backup over alternative cellular providers. Thanks to the per SIM dual APN

attachment, the router is managed "out-of-band", in analogy to managed land line services.

One Teldat router platform for all types of networks

The modular router device architecture adapts Teldat 2G & 3G cellular compact routers to many

types of WAN accesses - xDSL, Frame Relay, GPRS/EDGE and CDMA2000 - with a simple plug-in card

replacement. This unique feature not only protects the customers investment on Teldat technology, but it

also permits the enterprise to keep a homogeneous platform for heterogenous types of network accesses.

M2M Communication Application scenario I

M2M Teller Machine, retail or lottery machine services over 3G

The Teldat G4+ 2.5G cellular router shares the cellular

service between stand-alone serial / dialup payment

machines and the remote office LAN PC's.

The Teldat cellular router encapsulates and forwards the

native Teller Machine protocol into IP and forwards the IP

stream to the Central Office over 3G using standard

protocols - XoT, DLSw, etc. The privacy in the machine

to machine bank transactions is guaranteed with an

end-to-end VPN based on IPSec.

Since this approach is purely based on standards, the

central serving router does not need to be a Teldat one.

The Teldat G3+ 2.5G cellular router permits the PoS

(Point of Sale) dataphones (up to four at the same time)

and the office LAN PC's to share a single 2G/3G network

access.

The router encapsulates the PoS dial-up transactions into

TCP or UDP and sends them over 2G/3G. As in Scenario

I, the PoS machine to machine transactions are secured

with IPSec.

The central office serving router performs the inverse

translation to forward the PoS dialup payload to the host.

offering.

M2M Communication Application Scenario III

M2M Telemetry communication over 3G

Thanks to the support of the most demanded SCADA

protocols (Modbus, IEC 60870-5-101, IEC 60870-5-102)

in the Teldat G4+ and G3+ celluar router serial ports,

these routers can also deliver 3G services to traditional

telemetry systems.

In this example, the Teldat G4+ celluar router

encapsulates the Remote Telemetry Unit (RTU)

SCADA information into TCP/IP packets and sends them

over the 2G/3G network. As in the two previous

scenarios, the machine to machine data encapsulation is

based on standards, so the central service router does

not need to be a Teldat one.
