What do the terms GSM, GRPS, UMTS, HSDPA, LTE, etc. mean?

In the GSM technology glossar the most important terms are explaint. Feal free to follow the links to Wikipedia for detailed information about the specifi data transmission technology!

Mobile Technology (SMS, VOICE, 2G,3G,4G):

GSM = Global System for Mobile Communications

Mobile Data Technology (2G):

2G = the second generation of mobile phone standards (GPRS, EDGE)
GPRS = General Packet Radio Service
EDGE = Enhanced Data Rates for GSM Evolution

Mobile Broadband Technology (3G, 4G):

3G = the third generation of mobile phone standards (UMTS, HSDPA, CDMA)
UMTS = Universal Mobile Telecommunications System (UMTS, HSDPA, HSDPA+, HSUPA)
HSDPA = High Speed Downlink Packet Access (HSDPA, 3.5G, 3G+ oder UMTS-Broadband)
CDMA = Code Division Multiple Access (CDMA, CDMA2000, CDMA2000 EV-DO)

4G = the fourth generation of mobile phone standards (LTE, WiMAX)
LTE = Long Term Evolution (LTE, LTE-Advanced)
WiMAX = Worldwide Interoperability for Microwave Access

What does the middleware do?

The middleware collects measurement data via wireless measuring devices, stores the data on a central server and visualises it via myDataweb. Additionally the settings and the configurations can be changed with myDataweb and transmitted directly to the device via GPRS.

What is PAWN?

PAWN, formally known as SMALL, is a scripting language similar to C which runs on embedded systems.
Additional detailed information is provided on the website of the developers:

What about the measurement intervals?

There are recording intervals (data is stored) and measuring intervals (data is not stored). The recording interval amounts to max. 1 minute, the measuring interval amounts to max. 1 second. This ensures a quick reaction time. The intervals can be configured individually. Caution! Each measurement consumes energy and affects the lifetime of the accumulator. It is therefore important to choose resource-efficient intervals.

How much measurement data can be stored on accumulator devices?

he field devices are equipped with a ring buffer with up to 440.000 measurements (can vary from device to device). They can cache measurements taken in 1 minute intervals for up to 10 months.

How is the data transmitted?

The data is transmitted via GPRS to the server using a special protocol. With Managed Service Microtronics offers global connectivity at internationally standardized service rates.

What is important for a cost-optimal transmission?

The data volume is calculated by using the measurement and transmission intervals. The intervals are thereby adapted to your requirements. As it works with a very slim protocol, the Middleware basically gets along with a very minimal data volume.

Do I need a SIM card for the international data transmission?

No. The field devices from Microtronics are already equipped with an on-board SIM chip and are therefore globally applicable. Microtronics offers multi roaming GSM data transmission technology, that is to say: wherever you may use a device by Microtronics, the best available GSM network is automatically chosen to guarantee a reliable transmission of your data. Details see Footprint

What is the advantage compared to a radio-solution?

The radio network evaluation for the middleware can be done easily with your own mobile phone. The whole infrastructure (GPRS) already exists worldwide. There are no further costs incurred for complicated antenna technology, radio network establishment and radio network operation.

How long is the lifetime of the accumulator?

The accumulator or battery lifetime can last up to 5 years. It is, however, strongly depending on the measurement and transmission interval and the sensor's power consumption. Various battery sizes for ATEX and non-ATEX devices are offered: The exact lifetimes are calculated according to your special requirements.

Where is the data stored?

The data is at first buffered in the devices and automatically transmitted to your middleware via GSM/GPRS/UMTS/HSDPA/LTE on occasion of the next transmission interval.

How do I get access to my data?

The measurement data and the status of the measurement point are accessible via mobile phone or Internet from any location. The admission data is provided by the middleware provider.

Do I have to run the platform myself?

Not necessarily. On the one hand you can use the demo cloud platform from Microtronics as your infrastructure provider. On the other hand you can also buy your own license for the cloud platform. In this case the software can be installed individually (e.g. at Microtronics, at a hosting provider's data centre or at your own data centre).

How much data can be stored on the middleware database?

The database can store up to 232 data sets per device (this equals to 136 years when recorded every second).

Is the middleware also offered as an OEM solution?

Yes. The middleware was designed as an OEM solution and can be adapted to your corporate identity. A complete branding including devices is available on request. For further details please contact the Microtronics support team.

How often is on-site maintenance of the battery- and accumulator-powered devices necessary?

The necessity of accumulator or battery changes can be indicated via an alarm. No special tool is required for the battery change. The battery block of ATEX-devices can be changed in the ATEX zone without any problems. For devices with sensors you have to stick to the calibration intervals. The complete device can be replaced as the configuration settings are automatically passed on from the server to the new device.

How can the instrument be updated?

The firmware updates are automatically imported from the server. It is not necessary to see the devices on-site or re-programme it or to stop operations.

How long is the life cycle of the field device?

The average life cycle depends on the field of operation and application. When used appropriately the mobile field device will have an average life cycle of approximately 8 years. The batteries, accumulators and sensors are not taken into consideration in this calculation. When used inappropriately the field device's life cycle will be shortened significantly.

How long is the life cycle of a GSM module?

According to MIL-HDBK-217 MTBF the life cycle of a GSM module amounts to 45.1 years when used at 40 degrees operation temperature and is operated 1584 hours /year.

Who has access to my data?

Data access is limited to the provider and the respective customer and is secured by password.

Can hackers get access to my data?

No. The device is only communicating with your provider's server. The communication between device and server is encrypted. Access to the server is secured via a login and password as well as a fire wall.

How does the data encryption work?

The data encryption is subject to a 3-leveled encryption concept which is based on the BSI guideline TR-02102.

Can I backup my measurement data?

The measurement data is stored on hard disks on Raid network and can be integrated into the company's internal data back-up.

Can I also connect measuring points abroad?

Yes. The middleware was designed for the international usage. Languages, time zones and figure formats for the server and the measuring points as well as the accesses for providers and customers can be configured.

For which applications/environments are the instruments suitable?

The instruments are partly ATEX certified and IP66, IP67 and IP68 tested. For devices with an integrated sensor the IP protection rating is to be considered. The devices are exceptionally robust, resistant and surrounded by a protective shell. For further details please have a look at our fact sheets or contact the Microtronics support team.

How is data displayed?

There is a standard setting but also user specific views can be created. Data can be viewed in any way you desire: Graphs with several sets and different types of measurement data, special gradient calculations, calendar, visualisations, tables, lists, maps, current measurement data, downloads. Get a test account and experience the advantages yourself.

How do I receive an alert?

The alerting is configured upon the set-up of the measuring point and can be forwarded to you via SMS, e-mail, XML or FTP. The values for lower deviation, exeedance and hysteresis can be configured.

What is to do when the telephone number that was deposited for alert messages changes?

The middleware does not require complicated configuration of the telephone number on the device. The alert is easily changed online by the customer or the provider at any time.

Can I adjust the settings of M2M devices individually to the needs of my customers?

Yes. Microtronics offers M2M devices (e.g. myDatalogMUC) that are equipped with a PAWN script engine (programming language similar to C). This enables the creation of scripts that solve customer-specific tasks. You are provided with an editor with syntax highlighting for the direct programming of your M2M devices. Additionally you can use the editing tool on the cloud platform.Download  the software for the toolset for free.

Which settings can be changed via the user interface?

myDataweb offers several user levels and levels of access rights (administrator, provider administrator, provider operator, customer administrator, customer operator, default view administrator, default view operator).

How much time is required for the installation and start up of an additional measuring point?

Approximately 15 min. including the online configuration.

How does the administration of customers and measuring points work?

By simply clicking buttons online customers and measuring points can be added, configured, changed or deleted.

How many measuring points can be connected to a system?

The amount of measuring points is not limited.

How time-consuming is an update?

The complete middleware system is designed for full automatic updates. For customers with software service contracts the updates are automatically distributed from the maintenance and license server to the provider server. From there the firmware updates are automatically redistributed to the device.

Is it compulsory to use a server software or another service provided by Microtronics?

Yes. To ensure security it is required to use a server-side software. The software can be purchased as a service via a telecommunications provider or you can buy your own license from Microtronics.
