Dropping of SMS per person during Spring Festival

Dropping of SMS per person during Spring Festival During the Spring Festival, the volume of mobile short message service reached a record high, with a total of 31.17 billion mobile SMS messages sent, an increase of 8.3% year-on-year. Among them, on the New Year's Eve, 12.01 billion mobile phone text messages were sent to the peak, which was nearly 4 times faster than the daily average.

However, due to the increase in mobile phone users, the per capita volume is decreasing. As of the end of 2012, the number of mobile phone users nationwide reached 1.112 billion, which means that the number of text messages per person during the Spring Festival is about 28, slightly lower than the 29 per capita of last year. In Beijing, this decline is even more pronounced. From the data of New Year's Eve, Beijing mobile phone users issued a total of 1.16 billion New Year's greeting messages, and the average number of messages sent was 37, a year-on-year drop of nearly 10%.

The Ministry of Industry and Information Technology also pointed out that with the popularity of New Year of the Lunar New Year greetings such as WeChat and Weibo, voice services have been greatly affected, and the substitution effect of data services has appeared. During the Spring Festival period, the total time spent on cell phone calls was 42.01 billion minutes, which was only 80% of the daily call volume. In contrast, the mobile Internet access traffic reached a new peak - 19.715 million G, and per capita access traffic reached 26.4 M, 33.6% higher than the daily traffic.

The three major operators all felt this change during the Spring Festival. According to statistics from China Mobile, the number of text messages for the seven days of the Spring Festival (New Year's Eve to the sixth day) reached 24.3 billion, an increase of 2.5% year-on-year; but the most striking figure was another figure - data traffic increased by 105% year-on-year. Among which, Guangdong Mobile's data shows that its total GPRS traffic increased by 63.84% over the previous year, total WLAN traffic increased by 227.55% over last year, and total 3G traffic increased by 212.68% over last year.

After years of golden growth, mobile phone text messaging has finally slowed down. The money-saving, trouble-saving, and more interesting ways to pay for the Internet are eroding the market. According to the analysis of Ai Media, for consumers, the biggest problem with the New Year's greetings such as Weibo and WeChat is the uncertainty of information delivery. Although the cost of SMS is slightly higher, formal, direct, and reliable features still make it the majority. The consumer's first choice.

D-sub Connector Contacts
A D-sub connector is a form of connector commonly found in electronic and computer systems. It consists of a D shaped metal band and two or more parallel rows of either pin contacts (male) or socket contacts (female). D-sub connector contacts can vary in size, material, current rating, length and resistance.

The most common type of connector is the crimp contact. These are assembled by inserting a stripped wire end into the cavity at the rear of the contact. The cavity is then crushed using a crimp tool, gripping the contact to the wire.

What are D-sub connector contacts used for?
The D-sub connector contacts carry the signal from the source to the destination across the D–sub connection.

Types of D-sub connector contacts
Most D-sub connectors are supplied with contacts ready in place. Contacts can be replaced if damaged or if the application of the D-sub connector is to be changed from the original design specification.

High-current, high-voltage, or co-axial inserts require larger contacts. The material of the D-sub connector contact can be changed if the robustness or quality of the connection needs to be improved.
