Why is Nokia N73 IR much slower than Bluetooth?

The carrier frequency of Bluetooth is much higher than that of infrared carrier The higher the frequency, the greater the bandwidth, the faster the transmission speed is Shannon's formula cloud in information theory

Bluetooth is faster than infrared, and it is technologically advanced. Yes, yes.

Infrared is definitely slower than Bluetooth....I haven't heard of laptops using infrared Internet access.

The speed of the highway is not the same as that of the national highway! Similarly!

I used to help my friend find it and copy it, but it's very practical.

Mark both of these items as "Completed" at the end, and remember!

Once done, the N73 is fast, no matter what is turned on.

A friend asked if the date format has to be the day, month, and year, and the format I used was according to the year, month, and day, which was still very fast, as long as I understood the principle.

Hello, this kind of question is very simple, is your N73 licensed! If so, you can go to the after-sales service and ask the maintenance staff to upgrade your mobile phone software again!!

If not, just go to a larger maintenance place, spend 40 yuan, and ask the master to give you a software upgrade!!

The fatal flaw of the n73 is its slowness.

It's useless if you change the memory card, are you deleting the wrong place? Don't put anything into the memory of the phone itself, take a look at the grid.

N73 is notoriously slow, and there is no variation! It will be slower to change cards with large capacity, so use it!

Don't change the internal card to a bigger one, the bigger the card, the greater the amount of mobile phone resources consumed.

If you flash the machine again, it should be a problem with the software. n73 has a slow response problem, but not as serious as you say.

By the way, if there is a lot of information, it may be slow. Delete old messages!

If it is not caused by the fact that there are many things that are loaded, it may be the relationship of the signal ! Weak signal may also delay the sending of information!

If the signal is very good, the information is still released, and it is also possible that the information reception on your mobile phone motherboard is broken! It's good to repair it, and it's only 20 yuan.

I'm also using n73. I found that there is an application software in it, and there is a write e life in it. Will store your text messages like backups.

If you've never deleted it ... You can delete them all (but be careful, you can transfer your useful text messages and ** to the computer or something before deleting, because there will be none of them) If you have never deleted them, you need to be patient. Because it will be a long time.

Hahaha. The point is, you need to set it up after you delete it. Let this thing not record anything.

Hope it helps. Ha ha.

It should be useless to change the card, because the slow is the problem of the mobile phone, even if you remove the card, it is slow, and it is recommended to format the machine should have an effect.

Under the re-soft grid, mine is very slow.

N73's most fatal weakness is its low cache, which is manifested in slow response, but the firmware of the mobile phone can't be changed. Usually the phone has the highest cache when it is first turned on, and then the cache will get lower and lower as the program is opened and closed. So restart it every day or two.

It doesn't matter if you have a few frequently used programs, as long as you don't open too many at the same time. Also, you said that it takes a minute or two to send a text message, which seems a bit exaggerated, but it is also related to the signal, if the signal is not good, it will be difficult for any mobile phone to send a text message, or even send it. If the phone has been used for a long time, and you feel that it is a little slow and abnormal, much slower than when you first bought it, then you had better update the system, or the phone.

You can upgrade the system, you can go to customer service, or you can get it yourself; Grid machine is to enter * on the standby page, the original password 12345. Note that after updating the system and the phone, the phone is like when I first bought it, and the contents of the business card holder notepad are gone, so pay attention to making a backup. You can check the detailed method, so I won't say much about it here.

Rest assured, it will turn off on its own, don't move it, and it will turn off automatically after a minute

Yes, there is bluetooth, and there are bluetooth headphones.

90 percent of it works.

It can be used, if you want to buy Nokia, you must buy it in a regular store.

It will definitely work, I've been using Samsung before, and I'm still using it.

Listen to songs in binaural stereo.

Recommend Sony.

The brands are good, don't buy miscellaneous brands.

There are special headphones for Nokia on the market. As the saying goes, you get what you pay for. High, always has its benefits. If you don't want to buy a dedicated one.

The earbuds are fully charged first, and then press and hold the power button, note that you must continue to press and hold for 10 seconds and never let go.

During this period, you will see that the indicator light of the earbuds is blue at first, you don't let go when you see the light flashing, but continue to press and hold.

Until you see the light turn solid blue or the red and blue lights blink alternately.

First of all, make sure that the Bluetooth headset is charged, the first 4 hours, the next 1-2 hours will be fine, secondly, turn on the Bluetooth headset, press and hold for 7-8 seconds, make sure the headset has been turned on before letting go, and then turn on the mobile phone Bluetooth device search.

If it doesn't work again, it is recommended to try a different phone, or a different headset to try.

As long as your headphones are Nokia's, and there are no problems such as faults and no power, they will definitely be able to be linked, I suspect that you have not turned on Bluetooth, press and hold the button in the middle of Bluetooth, first a flash of blue light, and then a long red light, the whole process will take about 10 seconds, don't worry.

Bluetooth mismatch is impossible, it may be a problem with the signal transmitter in Bluetooth, the landlord can go to the maintenance department to check, I hope it helps.

I'm dizzy....It must be that the Bluetooth headset and your phone don't match...How much is your Bluetooth...My friend's mobile phone bluetooth headset and my 6120 can't be connected because the model technology is different.

Take a look at the manual.

Utopia Studio stays.

The speed is actually okay, absolutely bearable.

But importantly, it's almost the slowest of all smartphones, and it's not even as smart as it is not.

With 5700 ah. 6110 Ah. 5320 ah...

Much slower than these ...

is the slowest smartphone... Of course, installing a 2G card will be a little slower than a 1G card.

I only installed a 512m with 5700. I don't want to pretend more. I'm in a hurry. The phone is slow.,If the fire is big, I dropped only n73...

I've been using N73 for a year, so I don't think it's slow.

There is no way to compare with the N-series mobile phones after N73! The speed is not even comparable to the N70,

Anyway, 3-5 seconds slower than other phones is normal.

How can it be so slow.,My classmates used2G memory card,It's not going to be very slow.,Some operations are slower than my 53101 1 to 2 seconds.,But it's faster than me to play the web page.,N73 function is still pretty good.,It's acceptable.,Can you try it when you buy it?。

Nokia's mobile phones are slow, it's good to get used to it, other machines are fast, not as durable as Nokia, if you want to use it, use the brand of Aijian, top Nokia!
