Scalable digital signage solutions

Cell modem and router is the cellular device with USB/RS232 port or RJ45 ports. With cell modem and cell router, users and system intergrators can build network via cellular wireless network without cable lines.

Now here is a solution with the cell modem and cell router for short information.

Many industries benefit by delivering messages to their customers through digital signage including retail, leisure, hotels, finance and transport. It conveys data such as road traffic congestion, parking directions and passenger information for bus, rail and taxis to ease the decision-making process. Furthermore, digital signage technologies such as video, TFT, LCD, LED and VFD provide ideal mediums for advertising and promotional activities for generating new revenue opportunities.

Business Challenge
Lack of accurate and up-to-date information often compounds problems and increases frustration. Examples include traffic congestion and road incidents where early warnings help to direct traffic away from problem areas. In many cases, "content" needs to be delivered in response to real-time events such as parking availability, bus arrival times and excessive vehicle speeds. Delivering strategic messages to digital signage enables passengers, customers, staff and the public at large to make better decisions. Advertising and promotional opportunities exist for retailers and brand owners. These are especially powerful where there is a captive audience e.g. public transport and retail queues, taxis and public conveniences. Key issues lie with fast updates to remote and mobile locations, especially where they are not easily accessible or in dangerous locations such as track & roadside. 

Scalable digital signage solutions
Video, graphic and text signs support proprietary protocols at TCP/IP, serial or Ethernet level. Communication can be added to digital signage using a modem which offers simple remote access or perhaps a router for an Ethernet networked device.
An Internet enabled modem provides access to FTP download sites and a content delivery system offers a complete solution. Intelligent Internet enabled modems enable legacy equipment to be monitored, which can be scaled to a remote monitoring system solution, where information can be delivered in response to real-time events.

Simply words, the remote device connects the cell modem by USB/RS232 port and the cell router by RJ45 ports. Get a sim card for the cell modem and router, it dialup to the internet network to create the wireless networks.

GPRS/CDMA modem is with RS232 ports. And HSPDA / HSPA modem is with USB port.

Wireless M2M Solution for Energy with GPRS Router

GPRS Router is a good cellular device suitable for different wireless M2M solutions. With GPRS Router, users just get a sim card to build the network connection without cables.

Remote Management of a Natural Gas Pipeline
A natural gas company wanted to remotely control compressor stations that are located alongside a pipeline. Wiring costs can be high and wires get accidentally cutted, thus the solution had to be wireless. A major natural gas transportation and distribution company in Thailand wanted to have better control over their operations. The offshore and onshore transmission lines in their vast natural gas pipeline network are several thousands of kilometers in length. In addition, the distribution lines branch out from the transmission lines to serve various industrial users.

What is a compressor station?
An onshore gas pipeline is divided into smaller sections by so called compressor stations. It is natural to have small pressure differences along the pipeline. Compressor stations are instruments used for monitoring and compensating these inevitable but small pressure differences. A compressor station can also detect whether a leakage in the pipeline has occured. For billing purposes, a compressor station has gauges that measure how much a particular industrial customer has consumed gas.

Wireless beats wireline
A Remote Terminal Unit (RTU) interfaces with the electronics at a compressor  station. An RTU, in turn, can be connected to a centralized SCADA control center via its serial data interface. The natural gas company was looking for a reliable wireless connectivity solution as wiring costs can be high and wires can get accidentally cut. Not to mention high monthly communication costs.

Actually more cell router can do such jobs, such as hsdpa router, hsupa router and evdo router which is based on 3g technologies, and other Industrial Ethernet Router.

Cellular Router Solution for Electricity

The mobile cellular technology is affecting people in the life. Various kinds of cellular devices are used. Such as mobile phones, data card modem, cellular routers.

For industrial application, cellular modem and router can make wireless solution much easier. Here is a example for electricity applications.

The GPRS Router and HSDPA router are widely used for the solution providing the RJ45 Ethernet port for connections.

With rising energy costs there is an increased need to identify utility usage and waste. Take steps in reducing consumption through a remote management Automatic Meter Reading (AMR) solution.

Automatic Meter Reading Background
The traditional utility meter displays energy usage as an accumulation of counts presented to a display, which is used to calculate the monthly bill. It has applications within the electricity, gas and water utility industries for domestic, commercial and industrial applications. Sub metering is often used within a building, retail or industrial facility where it is desirable to measure power consumption for specific equipment, locations or sub-level accounts.

Business challenge
With rising energy costs and environmental pressures through the Climate Change Levy, there is a growing need to reduce power consumption. Reducing losses and waste, and adopting power efficient products and technology can achieve this utilising remote management.

However, since power losses are not easy to identify, it is difficult to determine the key culprits whether they are human users or power-hungry devices. In many cases it is difficult to store energy e.g. electricity, which must be generated to fulfill immediate demand. Predicting usage remains a key issue in an industry where downtime is unacceptable, which is made difficult by slow access to the remote meter readings.

Actually the mobile wireless router and modem are applied for many more applications, which build up wireless solution for costless, convenience.

Mobile wireless router has another version for non-industrial class, with no module inside. Users need get an external usb modem to work, which is called 3g usb router also.

GPRS Router and GPRS Modem

What is GPRS?

GPRS is a cellular network stands for General Packet Radio Service, and it is a protocol for passing data over a mobile phone network. Here is more info knowing about GPRS,

1. GPRS replaced dial-up cellular modem and cellular router Internet access, offering faster browsing of Internet content and email. It's an "always on" service".
2. GPRS on a cellular modem and cellular router doesn't use a phone number to connect; it uses something called an APN (Access Point Name).
3. GPRS has now been largely superseded by faster data network services known as 3G

Mostly the GPRS Router and GPRS Modem are the used to meet users’ internet connection at the beginning. And now the 3G modem and router are more and more popular for high data interconnections.

GPRS and 3G APN settings info.

Normally it requires the four parameters.

1.      Service code (dialing number)

2.      Username

3.      Password

4.      APN code

For example GPRS APN info in China,

Network Provider	Service code	Username	Password	APN code
China Mobile	*99***1#			cmnet
China Union	#777	card	card

And 3G APN info

Network Provider	Service code	Username	Password	APN code
China Mobile	*99#			3gnet
China Union	*99#			uninet

In a word, different network provider can use the same service code, username and password, but owns different APN code.

Normally, the 3G Router support WiFi feature, which is more convenient for users to share the internet via WiFi connections. Simply we call it as 3G WiFi Router.
For local wired connection, you can get a LAN switch if the LAN port of the 3G Router is not enough for use.

The 3G WCDMA speed arrives up to 14.4mbps or even higher, which is quite enough for normal internet browsing and data transmission.

The use of 3G mobile Broadband has increased with the availability of 3G USB Dongles that enabled a single user to connect to the internet without using standard wired broadband technology. The widespread availability of 3G networks and the reduced cost of mobile broadband have led to a revolution in the way that businesses and consumers connect to the internet for browsing and e-mail.
A 3G Router enables mobile broadband users to take the next step in providing high speed mobile broadband internet access for multiple users in the same way that a standard ADSL Broadband service can be shared between multiple PC’s and Laptop’s. The 3G Router uses a single 3G mobile Phone SIM card and provides wired and wireless WiFi connectivity as well as providing additional services such as VPN and Firewall.

Right now most common use 3G Router is HSUPA Router with 7.2Mbps download and 5.76Mbps. The test speed can arrive up to 6.2Mbps depends on networks because the speed will be affected by network crowd and users quantity. Local WiFi speed can get 108mbps or 300mbps which enough for multi-users to share the connections.
