SoMAX China Rail High-speed (CRH)

wireless internet service

National Pride – CRH SoMAX Wireless Solution

• Extending China’s national power – China CRH wireless internet solution, along with culture

presentations and business opportunities which come with this

solution, is a diplomatic tool to market the “Soft Power” of China

and to gain more influence in the world.

– With SoMAX technology, China will be able to demonstrate this

technology thus enhance its influence in the internet community of

the world.

• CRH data service – Utilizing unlicensed band

• SoMAX is an intelligent wireless subscriber relay

communication technology build up in 2.4/5.8GHz spectrums

that uniquely provides truly auto full mesh coverage.

• Eliminating the cost of acquiring licensed band – cost saving

• All of the handheld devices can use Wi-Fi to access the

internet regardless telecom carriers and internet providers.

CRH Security – SoMAX Advantages

• Leading technology – SoMAX advantages – Intelligent auto full mesh

• Design each node to be intelligent so it can co-work with other nodes to form

intelligent full auto mesh, which provide the base for upload and download.

– Best path anytime

• Each node is very smart. They can interact, communicate, and share network

messages to each other consequently maintain /balance the network

efficiency. Dynamically select the best node and best path for relaying data to

its destination.

– Multiple choice of paths to insure best connection

• Each nodes can see a number of nodes. If an active node for data transmission

is malfunctioning , the path will auto-adjusted by shifting to the next best

available node for continuing transmission. The network will not be affected

by the interruption and can certainly maintain its overall performance.

– Multiple layer Securities

• Intelligent path sections at any given moment - no fixed path from source to

destination

• Packets are forwarded with very low power consumption

• Devices cannot join the network without identification and authorization.

CRH Communication Safety – SoMAX Advantage

SoMAX secures CRH safety with steady connectivity • Control center can obtain real-time data in carriages for monitoring.

• Locating the carriages from messages of SoMAX devices on the

CHR track.

• In-cart IP cameras, uploading live video streams to control center

for monitoring, storage and future system optimization.

• Driver can see the carriages in the front and in the back in real-time.

When the distance is less than the safety requirement, it will

automatically alert the drivers and the control centers

SoMAX secures two way communication in CHR • Control & monitoring center can maintain high bandwidth

communication with each carriage.

Cost Advantage – SoMAX Advantage

• Best Cost Effective – A full distributed system

– Maximize the existing resources

• Utilizing unlicensed band for internet service on CRH.

• Deploying SOMAX devices along CRH track and

property – less trouble/hassle comparing to the base

station deployment.

– No base station and data center are needed

• SoMAX device has much better price advantage

compare to base station equipment.

• SoMAX network has no need for data center.

– SoMAX solution costs only 1/3 of the base

station solution.

Applications：Japan JR

• While the train is approaching to the

station, JR driver can access to live

video stream on the station for

assistance under cautionary intention.

• While making turns with blockage area

without direct visual, JR driver can

access the live video stream for

assistance under cautionary purpose.

Application：Shanxi Province coal mine monitoring

For the purpose of capturing the

environmental effect on coal mining,

The Department of Environmental

Control of Shanxi Province established

an environmental monitoring system.

Initial deployment included 50 mining

locations and will further extend to every

mining location within the Province.

Application：Hebei University broadband surveillance

CRH – Within the cart

• Communication at speed up to 400 km/hr

• High speed wireless internet: Any Wi-Fi

equipped device can access to the

internet once is connected.

• Cellular phone : Joined Femtocell to

SoMAX device to provide voice & data

service for operator customers.

Core Technology – SoMAX

• Using unique method to solve Doppler effect, SoMAX can provide internet service while traveling at the speed of 400 km/hr.

• Handover between cart APs and track APs in ms range - Outstanding

• Using unique method to form high speed full auto mesh. Each AP provides both routing and relying decision.

• Cart APs and track APs use multiple routing method, dynamically monitoring connections and choosing the best route for transmission.

• Using packet size transmission method to increase the transmitting speed.

• With multiple routing and packet size protocol, the system efficacy has been improved 200 times better than point to point transmitting protocol.

Conclusion

1、Unlicensed band

2、SoMAX always selects the best route

to insure the best connection

3、Support high speed mobility

4、Cost advantage

5、Less interferences

6、Adaptive power & adaptive routing

7、Can corporate with existing wireless technologies to enhance

SoMAX network system

SoMAX China CRH diplomacy is the best method to market

China’s “Soft Power”

It is everywhere – SoMAX is the best solution.
