Solar cells work - wireless access point

U.S. venture firms DropZone Networks, Inc. (hereinafter referred to DropZone) in the United States held in San Diego "DEMOmobile 2004", the public through the work of solar cells(pa3534u-1brs, pa3535u-1brs, toshiba satellite a200 battery, toshiba satellite a202 battery, toshiba satellite a203 battery, toshiba satellite a205 battery, toshiba satellite a210 battery, toshiba satellite a215 battery) attached to the server of the wireless access point function "IntelliEdge".

IntelliEdge used in the most embedded in the body 4 of the structure of wireless communication module. Supported by the module, in addition to wireless LAN module IEEE802.11a/b/g also includes wide-area wireless access systems, as well as 2.5G and 3rd generation mobile communication system and other modules. Through this interface, in addition to around the end can be used as the access point work, but also can be formed around the mesh network access point.

These functions can be used in the communications infrastructure or power of the region is still not perfect wireless network. It is said that, DropZone Corporation was considering the use of IntelliEdge for developing countries to build a communications infrastructure. Not only that, but even the communication facilities of the cities also have the possibility to import. For example, for portable terminals, as well as the IP telephone network game server and so on. "IP telephony, and online games are very sensitive to the delay time. If you use this product, it can be in the streets, such as power supply is not easy to find places to form a network, at the same time has the edge because of its servers, so the packet can be avoided in the service provider router Jump among many. This will effectively reduce the delay time "(the company founder, chief technology officer David Spector).

Ready access to electricity for the heavy solar panels of 0.9kg. This voltage can charge 12V batteries of 20Ah. According to Spector, the first charge IntelliEdge work to ensure that 3 to 5 days. In order to reduce the power consumption, "in addition to carefully chosen components, but also carried out wireless transceiver control" (Spector). Aspects of components, such as micro hard drive is used in Hitachi Global Storage Technologies products, Intel introduced the microprocessor's "PXA255". IntelliEdge plans Q4 2005 begun shipping. The current pricing situation is not clear.

Inferior battery problems and more frequent cell phone into a grenade

  In recent years, the "mobile explosion" heard the news, day and night together with our mobile phone has become a time that will not be allowed to "attack" time bomb. It is understood that the fake cell phone battery explosion is the main culprit. Although one false dens were destroyed one after another, but there are still a number of mobile phone batteries(toshiba satellite l203 battery, toshiba satellite l205 battery, toshiba satellite m200 battery, toshiba satellite m205 battery, toshiba satellite m216 battery, toshiba satellite pro a200 battery, toshiba satellite pro a210 battery
) and shoddy flows openly in the market, into our own hands. Who can restore our sense of security? I am afraid this is not available within a short-term answer.

July 12, 2004, Guangxi Nanning, Ms. Wei on his way from work using a mobile phone call, call the end of the phone suddenly exploded. Hospital Diagnosis: Miss Wei phone explosion led to cerebral concussion, left face, left shoulder contusion and soft tissue, skin abrasions on his left shoulder.

This is not the first mobile phone this year, for the protagonist of the explosion.

The sound of explosions one after another phone

In January 2004, Shenzhen phone suddenly exploded, resulting in the bombing of Black pants, his right leg was also severely burned; February 2004, Mr. Xu, Beijing, spontaneous combustion occurred in the mobile phone, mobile phone has become a burnt instant Reactor powder; in April 2004, Hong Kong's first mobile phone battery explosion, resulting in the right eye and nearly blind; in May 2004, after less than a month, with Hong Kong mobile phone explosion occurred, resulting in a number of burned hands and feet ; in July 2004, a 16-year-old California girl clothes, cell phone pocket suddenly exploded in the second degree burn lead.
     Incidents in previous years, the same is startling: In 2003 the evening of March 6, Xian She explosion at home phone, mobile phones are all over the wreckage, one to three meters apart lobes wooden wardrobe breakdown; October 2003 , the Netherlands on a user's mobile phone pocket explosion wounded leg; in November 2003, Norway took place 3 times Nokia spontaneous combustion or explosion, in which an accident, the user first appeared in their Nokia mobile phones to take breathing phenomenon, when mobile phone users will be out after the explosion of mobile phones; Also in November, a Finnish woman, mobile phone battery explosion and sustained minor injuries; and Shenzhen Baoan Miss Fu installed in the pocket of his trousers because of the phone battery in a sudden burst , thighs burned 10 became disabled.

Inferior battery into a time bomb

From Beijing to Shenzhen to Hong Kong from the mainland, from home and abroad, mobile phones can be repeated explosions, so that sensitive people can not go to bed. How we actually had the phone? If the mobile phone explosion of small brands also be forgiven if, some, such as Nokia, Samsung, NEC international brands are also frequently "caught"?

The study found that these explosions are the crux of the phone battery(PA2487UR, PA2487UR-G, Satellite 510 Series, Satellite 4300 Series, Satellite Pro2100 Series amd 182281-001, Evo N100, Evo N1000V, Business Notebook nc8000, Presario2800T) in the phone. According to experts explain the lack of time the battery discharge, high and low temperature performance of non-compliance would adversely affect the normal use of mobile phones. Some unscrupulous manufacturers to reduce costs and the use of battery removed from the waste to the production of the old cell phone batteries batteries, and some leave short-circuit protection is installed, and some did not short-circuit protection equipment, such as batteries not related insurance guns, by the This is not hard to understand why so many mobile phones will "fire" exploded.

These fake mobile phone batteries in our penetration in life, almost to the point where the all-pervasive. The recent situation in Beijing, the technical quality of the supervision of the city's 16 malls 19 kinds of mobile phone battery products (all for domestic brands) for sampling, only nine kinds of products were qualified, a failure rate as high as 53%. Why could these fake mobile phone batteries "in order to drive evil is," to occupy a prominent market position, we have no choice but the consumers.
