Original title: "when you bought a PHS from Gao Qiqiang."

In the "raging" of the recent fire.

The two brothers of the Gao family earned their first bucket of gold through PHS.

So, with PHS, you.

Do you need to buy another 5G mobile phone?

Let's first come to a conclusion: if you have money, buy it all!

The reason is, listen to the editor in detail.

01. Where can you get through to PHS, as an extension of the landline, to access the local fixed telephone network (PSTN) wirelessly, so that the traditional fixed telephone is no longer "fixed", so that we can freely move and use within the coverage area of the wireless network when we communicate.

In a word, only local calls can be made!

5G mobile phone is an independent mobile terminal. When a Beijing (home) user makes a phone call in Nanjing (roaming place), Nanjing will establish the user's temporary file, and the Beijing network will save the user's Nanjing network information, thus realizing roaming intercommunication.

In a word, the whole world can talk on the phone!

02. What kind of sound quality can you hear? the call uses ADPCM coding technology, which is an improvement of traditional PCM coding technology. The sound quality is similar to that of landline phones.

5G mobile phone, through VoNR voice scheme, using EVS codec, has stronger anti-frame loss, anti-delay, anti-jitter and high fidelity capabilities, reaching the sound quality level of high-fidelity headphones.

03. Whether there is any delay between you and TA is limited by the technology at that time. The call delay of PHS will reach about 1 second.

Needless to say about the delay of 5G mobile phones, let's review the low latency knowledge of 5G again-as low as 1ms.

If 5G communication is like sending data packets on an airplane, then PHS is like a postman on foot. In short, it can be delivered to ~

04, do you have no signal PHS uses PHS signal transmission technology, its signal strength is about 10mW, in the process of penetrating thicker buildings will produce higher signal loss, resulting in PHS signal will be some weak indoor.

When it comes to 5G mobile phones, although limited by the 5G frequency band, the penetration of 5G signals is weaker than that of 4G. However, with the blessing of multi-antenna technology and beamforming, and at present, major operators are increasing investment in micro-base stations to ensure indoor coverage, it is believed that our 5G signal will become stronger and stronger in the future.

Can you send a small composition? do you remember when we had to read long text messages in separate sections?

Because the empty port protocol used by PHS stipulates that the maximum length of short message content in UUI is 116bytes, when the length of short message received or sent by the terminal is more than 116byte, the short message center divides the short message into multiple pieces so that the terminal can accept it.

5G messages are constructed based on GSMA RCS UP standard, which can realize the multimedia and lightweight of messages. For individual users, 5G message breaks the length limit of each message by traditional SMS, and the content will also break through the limitation of text, and realize the effective fusion of text, picture, audio, video, location and other information.

06. What games can you play? the games of PHS are really limited. Do you remember the days when we secretly played black and white chess and played gopher?

5G mobile phone, you know, the theoretical peak speed of data transmission reaches 10Gb/s, Masters × ×, Jedi × × all kinds of mobile games have no stutter burden.

07. How much do you have to spend on PHS? Gao Qisheng told his brother, "rent 20 a month and make a phone call for 30 cents per minute." it was really not expensive at that time.

Speaking of our current 5G package, harm! It's because we need a lot!

After this comparison, do you think PHS is a sharp tool for our work?

Save money!

Ensure daily correspondence!

Block all entertainment!

But we work hard.

Just to be like Big Brother.

Use your new cell phone and live in a big house.

The premise is to be a good law-abiding citizen! )
