The Basics of Wi-Fi

Have you noticed some routers have 2 signals?

They are called SSID and each signal serves a purpose. One is for speed, and the other, for coverage. Not all devices can see both signals because the 5 Ghz signal is a newer technology, but all of them use the 2.4 Ghz signal.

The 2.4 Ghz technology has been used for years. Before its use for wireless internet it has been used for cordless phones, microphones, CB radios, microwaves, and Bluetooth devices, among others, which makes it the most used frequency. 2.4 Ghz reaches a long range, but it receives lots of inference.

 

The 5 Ghz frequency is better because it has not been used as much and is currently dedicated mostly for Wi-Fi internet, though its caveat is a limited range. 

A new technology called Wi-Fi 6 is set to launch this year (2019). Wi-Fi 6 uses both bands, 2.4ghz and 5ghz, and cramps more channels in each band, which allows for faster speed and an expanded range.

Wi-Fi 6 is supposed to be up to three times faster than what we are used to, which will allow us to get the most out of our internet connection. Wi-Fi 6 also comes with new security protocols, resulting in a more secure connection for users.

Publisher's Note

There is an idea that most Latino immigrants who come here lack education, and thus are bound to perform jobs that require more physical abilities than intellectual ones.

The laborers usually receive a negative stigma, even though the United States society requires these types of jobs to function properly. It is important to us to remember there is dignity in any job. 

In our Líders section, we feature Mari Alejos-Puente, an entrepreneur who is succeeding in the cosmetics’ industry. She graduated from Tulane University and Xavier University and she told me how her mother and her grandmother  were part of the cleaning crews at these institutions, respectively, and how proud they were to see her obtain her undergrad and master degrees.

It is a beautiful thing when you know ladies like this mother and grandmother work hard to give a better life to their children. I wanted to mention this as a side note, because it is important to highlight their efforts, just as much as the effort of the highly skilled professionals we are featuring in our cover story.

In our cover we feature three Latin American physicians who are giving individuals a second chance in life with through their commitment and work at the Ochsner Transplant Institute.

Let his note be a reminder that Latinos, in every field, are providing their skills, talent, and sacrifices every day to make the United States a culturally and economically stronger society.
