When the "Star Map Positioning" of the mobile phone is turned on, a map of the location of the mobile phone holder is displayed on the mobile phone screen or the computer screen, and the "avatar" of the tracked mobile phone is clearly displayed at a certain position on the map. . When the travel team is lost or lost, as long as the mobile phone has power and is in standby, it will be able to find the lost person through the GPS function of this mobile phone.

How can a mobile phone know its location? It turned out that some mobile phone manufacturers installed a small global positioning system (GPS) in their mobile phones.

The Dopod GR232 kit is a combination of a locator and a set of software. This version of the software is only for PPC, you can use 696 for installation trial.
The positioning speed of GR232 is still relatively fast. In relatively empty areas, satellites can be searched in one minute. In more high buildings, GR232 can also capture relatively weak satellite signals. Offset of meters.

Miss Ho said that private cars are now becoming more and more popular. The way of vacation has been improved by trains and planes traveling collectively to groups of small groups. In order to save on the high communication costs during travel, people are now buying walkie-talkies. She also repeatedly recommended to me: "When several cars are lining up, the first car can use the intercom to inform the car of the traffic in a timely manner to ensure the safety of the road; in areas where there is no cell phone signal, the walkie-talkie can prevent members from falling behind or get lost; the intercom is in the ' "Survival in the wild is even more important.

If two or more vehicles travel together, they can be equipped with such equipment, which is convenient for communication at any time, but also saves mobile phone bills, making up for the lack of mobile phone network. If you use a radio, you can also contact local radio enthusiasts in an emergency to seek help.

The latest "armor" warrior Nokia 5140
The latest "armor" warrior Siemens M75
Mr. Li’s footprint may have spread all over the country. Whenever he takes a long vacation, he always has to travel. Therefore, a lot of cell phones are broken, but almost all belong to the same type of death method: "fall" is bad, water strikes, and the ability to resist pollution is extremely low. Document.write("");ad_dst = ad_dst+1; May 1st last year, he and his friends came to Shanxi together, and he could not imagine that he had broken several mobile phones along the way. One of them fell off the mountainside and was "crashed and broken," while others encountered heavy rain due to sudden heavy rain on the mountain. It is estimated that the possibility of re-starting in the near future is minimal. Watching the "beautiful love machines" suffer from torture, it really hate why mobile phone manufacturers have not designed a cell phone that is not afraid of fear. Don't worry, there are really mobile phones that are not afraid of wind and rain and are not afraid to beat. This is the three anti-mobile phone. The definition of the three defenses is shockproof, dustproof, and waterproof. Here are some models that are suitable for field work and field trips.
There is a "R310sc" waterproof mobile phone known as a shark machine. Its waterproofing mystery is to use a waterproof membrane to plug the data line interface that is easy to enter the water at the bottom of the fuselage to prevent water droplets from penetrating under the phone. And there is a waterproof membrane on the battery. After covering the battery cover, it can ensure that dust and water droplets do not penetrate into the cell phone.
The battery cover behind the R310sc is sealed in a special way. It has two upper and lower buckles, which is more compact than the other three mobile phones on the market.
Nokia's 6250 and Sagem MWX1 seem to be more powerful than other rivals. It is because the other three mobile phones are only resistant to water rather than real water resistance. The popular point is that it can be wet, even under the tap, but if it is really immersed in water it may be broken. The Nokia 6250's body is sealed with a shell, the body has a waterproof film inside, the receiver, microphone and buzzer and other parts more waterproof and dustproof protective film, display and keyboard are also embedded in ultrasonic technology On the shell, it is fully waterproof and dustproof. So even if the mobile phone is thrown into the water from a high place, you can still continue talking on the phone. According to evaluation reports by authoritative evaluation agencies and manufacturers in foreign countries, the Nokia 6250 and Sagem MWX1 can support one minute of water under 50 degrees and half a meter deep! ! ! See clearly, it is water for a minute.
However, it is not easy for these two phones to be found right now. Recently, two three-armed “armored†fighters have been listed: Nokia 5140 and Siemens M75.
