I haven't come to pollute the air for a long time ~~
Today, Shanghai is snowing. Unfortunately, it's not in Pudong.
Recently, I had the honor to cooperate with Huawei to develop software related to 3G. So I have learned a little about it. The ideal 3G device should be a mobile broadband modem. on the contrary, I consulted some business experts and found a fixed-line connection in the TD device. Moreover, Huawei also needs 3G mobile phones, which are said to be an arrow in the revenge of PHS.
Mobile phones are consumer goods, against Huawei's tradition, and upgrades are too fast. RF, IC, screen, software, and appearance are not strengths. Mobile phone replacement is fast, and communication components are relatively stable, so there is no need to work with the mobile phone in the mobile phone.
It is better to honestly turn 3G terminals into modem, there are too many personal terminals now, palm/PPC .. the above software is quite mature. It is better to provide wireless access directly and upgrade existing devices to 3G devices directly. IP-based services are the spring of 3G.
I think there is no mobile phone in the 3G era. The current pda can be used as a mobile phone as long as it can access the Internet. It is free of charge, and it is also cheap to switch to fixed-line phone. The price does not need to be exploited by telecom companies.
As a result, 3G mobile phones are not as good as researching various PDA asshole (my PDA is always dead, and Py is often used. However, here, Py is the communication interface ).
Currently, there are a wide variety of devices. If they can be used for their py, it is not a good thing for old devices to become 3G young. In addition, the 3G standard is not met, and The py standard is also good. Nowadays, all kinds of mobile phones/PDAs are too far away, and Py is too messy. The first time I saw a coin-operated mobile phone charger, I thought I was buying a wire.
Many devices support USB and Bluetooth. It is better to use these existing standards.
The 3G modem can also be used as a mobile wireless hub to provide wireless access for vehicles and subways.
People outside the industry are talking nonsense. Welcome to the discussion.
