Data Service

After the E3372-325 is connected to the PC through the USB interface, the E3372-325 will automatically connect to the network. Users can directly use the APN parameters preset on the page (or configure the APN on the E3372-325 web page) and establish a connection to access the Internet.

SMS

The E3372-325 supports message writing/sending/receiving. The E3372-325's web-based management page provide powerful SMS management functions, including Outbox, Inbox, and Drafts.

Functional Modules

1. Radio frequency module: Sends/receives radio signals and modulates/demodulates radio signals and baseband signals.

2. Baseband signal processing module: Processes LTE/HSPA+/HSPA/UMTS baseband signals, including:

Modulating/demodulating LTE/HSPA+/HSPA/UMTS baseband signals
Encoding/decoding LTE/HSPA+/HSPA/UMTS channels

3. Platform Service Subsystem: It initializes programs, diagnoses the running of the system, downloads data and serves as a watchdog.

4. Bottom layer driver: Drives peripherals, including USB devices, LED and USIM/SIM.

5. Protocol stack system: Processes protocols of LTE/HSPA+/HSPA/UMTS.

6. Application system: Send the laptop's commands to the underlying protocol for processing and return values to the laptop. Existing applications include: call management, SMS management, PS/CS domain service management.

8. Web Server: Provides server programs for Web client programs.

9. Web client application: The configuration management of the E3372-325 and related services are realized through the WebUI.

Explanation of frequency bands

When choosing an antenna, pay attention to which frequency bands the antenna supports. Depending on which operator and where the antenna will be used, the frequency bands vary. Larger cities use 2600MHz while smaller towns use 800/900MHz with some support bands in between such as 1800/2100MHz.

A higher frequency band gives a higher speed but also has a shorter range. The same applies to the antenna, if you have a base station that transmits on 2600MHz, your antenna, antenna cable and the location of the antenna become more important than on a lower frequency band. Explanation of signal loss we will go through soon. Higher frequency bands also mean shorter range from the base station.

450MHz (coverage band) also known as the Net1 band is the frequency band that covers the most area in Sweden. Therefore, Net1 is known to be able to have reception where other operators don´t have a chance, but with low download and upload speeds. The reason why this band is called Net1 is because that the company Net1 has exclusive rights to this frequency band.

800MHz (coverage band) is used by all common operators, excluding Net1. The low frequency band means that 800MHz covers a lot of space. Therefore, the band is used outside big cities or smaller towns. 800MHz is the most used frequency band around Europe.

900MHz (coverage band) is the band that Tele2 and Telenor initially used as coverage band. 900MHz is a more unusual LTE band and in the beginning the band caused some problems when the clients (mobile phones etc.) could not connect to 900MHz. Today, the mobile phone manufacturers have adapted the mobile phones to be able to communicate on 900MHz.

1800MHz (capacity band) is the latest frequency band launched. All operators today use this band in metropolitan centers (apart from Net1).

2600MHz (capacity band) is a very well-used frequency band all over Europe. 2600MHz is the highest frequency band used for LTE, this means that the band also has the shortest range compared to 800/900MHz. Due to the high capacity, the band is used in metropolitan environments where many base stations are required to cover as much surface as possible and have as high a capacity as possible.
