Different Cellular Router Types

Brief

As we know, cellular router is more and more popular in our living world. From normal internet connection for SOHO or personal use, to industrial class application, everywhere.

Cellular router devices can help you to visit internet or build a private connection anytime, anywhere, costless, conveniently.

Cellular router contains the following types:
1. GPRS Router – people also call it 2.5g router, working on GPRS networks, and back compatible to GSM networks.

2. EDGE Router -- people also call it 2.75g router, working on EDGE networks, and back compatible to GPRS/GSM networks.

3. CDMA Router-- people also call it 2.75g router, working on CDMA1x networks

4. HSDPA Router – people call it 3G mobile router, working on HSDPA networks, and back compatible to EDGE/GPRS/GSM networks, upgrading from 3g umts router.

5. HSUPA Router – upgraded from HSDPA router, working on HSUPA networks, and back compatible to HSDPA/EDGE/GPRS/GSM networks

6. EVDO Router – another 3G router working on EVDO and CDMA1x networks.

Speed comparation

HSUPA Router can reach 14.4Mbps download, and 5.75Mbps upload. And can upgrade to HSPA+ providing higher speed.

HSDPA router can reach 7.2Mbps download and 384kbps upload.

EDGE router provides 384kbps speed, and GPRS Router provides 206kbps speed.

EVDO Router gets 3.1Mbps speed and CDMA1x router gets 153kbps.

So for high data internet connection, HSPA Router, HSPA+ Router, HSUPA Router, and HSDPA Router are the best choice. EDGE/GPRS/CDMA1x Router are for Industrial Ethernet Router for small data size transmission applications.

Weather Monitoring

Nowadays wireless M2M is with high requirement and in fast growing. The wired solution is a traditional solution with cables, which bring the construction and operation difficulty. The wireless M2M solution make it easier with wireless cellular connections.

The 3G UMTS Router is one of the cellular device. 3G UMTS Router is a wireless cellular router working under 3G UMTS networks upon HSDPA/HSUPA.

The 3G UMTS Router is also called mobile wireless router as it is working in mobile networks. Cellular network is a mobile networks.

Details of solution of weather monitoring

1.    Summary

The development of mobile communication and Internet technology is bringing profound changes in the society, and the mature wireless data transmission technology is applied in many industries. The wireless terminal of Shenzhen E-Lins Technologies also provides a new means for the data transmission of the measurement and control system. Multi-factor automatic weather stations are based on this purpose. It has stable performance, flexible networking means, low requirement of operating environment, and good guarantee of power supply; it is mainly used for automatic monitoring of mesoscale synoptic systems, and can automatically collect, process and store all kinds of weather factors on the ground, and automatically send data observed. It is the indispensable advanced device of meso- and micro-scale systems for encrypted monitoring, forecast, scientific research and anti-disaster information system.

2.     Basic Functions and Application

3.1.1 Multiple Communication Means and Flexible Networking Methods
Communication means supported include GPRS, GSM (SMS), CDMA, RS232, RS485, etc. The remote stations can select the appropriate communication means according to the actual situation, so the networking is flexible.

When the communication means of combining GPRS/CDMA and GSM (SMS) is used, DTU (communication module) of E-Lins has the function of automaticly switching between two channels to ensure real-time communication.

3.1.2 Collector and Communication Module Monitoring Each Other
The collector and the communication module can monitor each other’s operation, and both can enable the processing program in case of abnormity.

3.1.3 Automatic Warning
When the observed data exceeds the threshold, the warning report of observed data is automatically generated and the HMI is informed.

3.1.4 Self-diagnosis of Operation Status
The operation of the collector, the status of the sensor and the condition of power supply, etc. can be monitored, and reports are periodically generated and transmitted to the HMI for monitoring the remote and automatic station.

3.1.5 Remote Processing
The collector provides the remote processing function, and allows the HMI to remotely operate the automatic station through all kinds of communication means, such as requesting for observed data, requesting for operation data, maintaining the collector remotely, etc.; provides commands of collector terminal, and can enter the collector terminal to search and collect all kinds of operation parameters.

3.1.6 Big Storage Capacity
With the internal storage of 1.7M and external extended storage greater than 160M. Observed data can be stored for more than 1.5 months continuously.

3.1.7 Good Power Supply Guarantee
Master and backup power supplies are used. The solar cell is used with the big capacity, high performance storage cell to supply 12V DC master power for the system, which ensures above 30 days of endurance of the storage cell in continuous overcast and rainy days. When the master power supply is cut or the voltage drops below the setting, the system will automatically switch to the backup cell; when the capacity of the backup cell drops below the setting, the power supply of the communication units that consume much electricity will be cut automatically to ensure that the collector can still work normally for a long time and ensure the completeness of the data collected.

The power supply has the function of monitoring the voltage of cell, with over voltage and over current protection.

3.1.8 Extensible Factors
HYA-M type automatic weather station has many input channels. In addition to collecting temperature, precipitation rain fall, wind direction, wind speed, etc., other factors such as air pressure, humidity, visibility, solar radiation, ground temperature, soil moisture, etc. can be extended according to the need. The processing program inside the collector has the function of extending a number of factors. Additional setup is not needed, and you simply need to connect the sensor.

Application

HYA-M type automatic weather station has good functions, so it is very convenient to use and maintain. Figure 3 describes the application of HYA-M type automatic weather station.
