Do you want to speed up to a “Long Term Evolution”? With Quectel modules it´s already possible…

Company Quectel brings to a market its first high-speed module EC20 which you can try yourself. More than fifty developers worked for over ten months on this module.

We´d like to share with you its parameters, as well as hints, which can make your work with this module easier – this is our biggest bonus to sale of modules from company Quectel.

Are you interested in compatibility with previous modules?

Module EC20 arises from the M10 GPRS module and the UC20 UMTS module. These modules can be designed to a PCB in a way that you have ensured variability and a possible replacement in case, that you wish to have one board for several solutions …

From theory to the praxis…

Discussions about LTE already last for some time. One LTE transmitter (800MHz) manages up to six times bigger area than one UMTS transmitter (2100MHz). LTE protocol is already from the beginning (in contrast to UMTS) written as a high-capacity with a fast response. The first phase of area coverage is usually equal to speed of UMTS uplink/downlink. After reaching almost a 100% coverage, then usually starts the second phase, which actually speeds up to current theoretical speeds of 172,8Mbps (downlink) and 57,6Mbps (uplink).

Let´s have look at frequencies

In presence, 4 bands are functional – on frequencies 800/900/1800/2100MHz and the 2600MHz band is not used so far. EC20 manages all these bands. EC20 will be produced in 2 versions, as EC20-E (for Europe) and EC20-A (for USA). Do you know that in USA also the 1559 to 1610 MHz band was approved, which however should interfere GPS signal in 1525 – 1559 MHz band, according to measurements?

And at last – advantages of EC20
  • No doubt and after experience with developers – the LCC package offering a possibility to assemble by hand or by machine.
  • Module is not the smallest LTE module in the world, but belongs to the smallest LTE ones. EC 20 also incorporates implemented GPS/GLONASS receiver.
  • Supports MIMO technology – multiple-input multiple-output, i.e. – multi antenna systems.
  • The EC20 module is able to communicate via USB port in Windows, LINUX, as well as in Android.
Frequently discussed eCall

The EC20 module also supports „emergency call“. In the time of creation of this article it was decided that eCall will be compulsory in vehicles from April 2018. In every way, company Quectel is already prepared and supports this system in almost all its modules.

The eCall function also related to another advantages and functions in the module, for example:

  • Low power consumption
  • High RF power and high sensitivity <-108.5dBm
  • Fimware can be updated remotely – DFOTA (firmware over the air)
