From search engine, Google entered into manufacturing of devices and is now foraying into thewireless network business. Reports said that Google will fund and help run wireless networks in emerging markets, specifically SubSaharan Africa and Southeast Asia.
The aim is to improve Internet speed in areas outside major cities where wired Internet connections are not available, The Wall Street Journal reports, citing people familiar with the Google strategy.
An indicator of Google's move is the tech giant recently applied for a license to create an experimental radio service from its Mountain View headquarters.
由搜索引擎起步的谷歌在跻身设备制造业务后,现正在尝试进入无线网络业务。有报道称谷歌将会筹资并协助在一些新兴市场开设无线网络,特别是在撒哈拉以南的非洲和东南亚地区。
《华尔街日报》援引熟悉谷歌商业策略的人士发言称,谷歌的目的在于为那些没有有线宽带连接的大城市周边地区增强网络连接速度。
谷歌近日申请许可,以从其位于美国山景城的总部开设一个用以试验的无线电通讯服务。这也许正表明了谷歌打算跻身无线网络服务。

无线局域网是无线电波作为数据传送的媒介,传送距离一般只有几十米。接下来小编为大家整理了无线局域网的新标准,希望对你有帮助哦!
With portable computers and wireless LANs, users can enjoy greater productivity while away from their desks, whether they are in conference rooms, public areas or remote offices.
Until recently, however, wireless LANs were too slow for most enterprise applications.based on the IEEE 802.11 standdrd, they ran at 1M to 2M bit/sec.
Now a new high-rate extension to the standard, 802.11b, lets wireless networks support data rates to 11M bit/sec.
Ratified in 1997, the original 802.11 standardunited the wireless industury by defining a low-level protocol architecture that worked with conventional upper-layer enterprise protocol stacks. Also, 802.11 maintained compatibility with the three mostpopular radio transmission types: direct sequence spread spectrum, frequency-hopping spread spectrum, and infrared.
Essentially, this new architecture added intelligence at the medium access control(MAC)layer 2 and at the physical(PHY)layer 1, fosteing cooperation between the two layers in performing the critical tasks involved with initiating and maintaining wireless communi-cations.
For instance, to ensure reliability of the wireless link, MAC and PHY work together to determine if a clear path exists before they start a transmission.
During transmission, they employ special collision-avoidance and arrival-acknowledgment techniques that are not required in wired ethernet LANs.
In september 1999, the IEEE approved a new designation, known as 802.11.intended to retain the error-correction,security, powermanagement and other advantages of the original, a key ingredient-a thchnique for increasing bandwidth to 11M bit/sec.
Called complementary code keying(CCK)the technique works only in conjunction with the DSSS technology sprcified in the original standard . it does net work with frequency-hopping or infrared transmissions.
What CCK does is apply sophisticated mathematical formulas to the DSSS codes, apermitting the code to represent a greater volume of informitter is now able to send multiple bits of information with each DSSS code, enough to make possible the 11M bit /sec in the original standard .
The 802.11b standard benefits users by delivering wireless ethernet speeds of 11M bit/sec that can reliably support everyday business applications, e-mail, internet and server network access.
With support from the new wireless ethernet from the new wireless ethernet compatibility alliance, founded by 3com, lucent, nokia and several other companies in the wireless LAN business, the new standard will also promise certified interoperability across multivendor platforms.
Finally, the 802.11b standard serves as a clamoring for a simplified wireless LAN landscpape.
Vendors can now focus on a single, high-speed standard, and users can cut through the clutter of wireless options by fovusing on a standard that delivers multibvendor interoperability and the performance to meet their application needs.
有了便携式和无线局域网,用户在离开其办公桌的时候,不管是在会议室、公共区域还是在远处办公室,都能享有更高的生产效率。
然而,时至今日,无线局域网对多数企业应用来说还是太慢。依据IEEE802.11标准,他们运行速度为1兆至2兆位/秒。
现在对此标准的一个新的更高速扩展,能让无线网支持高达11兆位/秒的数据速率。
最初的802.11标准是在1997年提出的,通过定义能与常规的上层企业协议组一起工作的低级协议体系结构,把无线行业团结起来了。802.11也保持了与三种最流行的无线电传输方式(直接顺序扩频、跳频扩频和红外线)的兼容性。
本质上,这种新的体系结构在介质接入控制(MAC)层(第二层)和物理层(第一层)增加了智能,建立这两层之间在执行及开始和保持无线通讯的关键任务时的协作关系。
例如:为确保无线连接的可靠性,MAC层和物理层一起工作,以确定在他们开始传输之前是否有一条清晰的路径。
在传输过程中,他们采用有线以太网不需要的、特殊的避免碰撞和到达应答技术。
1999年9月,IEEE批准了称作802.11B的新名称,作为802.11的高速扩展。此新的802.11B标准在保留原标准的纠错、安全、电源管理和其他优点的情况下,增加了一项关键内容,即把带宽增加到11兆位/秒的技术。
此项技术叫做互补码键控(CCK),他只与原标准中规定的直接顺序扩频(DSSS)技术一起工作,不能用跳频或红外线传输方式工作。
CCK所做的工作是把复杂的数学公式应用于DSSS代码,以允许该代码在每个时钟周期表示更多的信息。现在发射机能在每个DSSS代码中发送多个信息位,足以实现每秒11兆位/秒的数据传输率,而不是原标准的2兆位/秒。
802.11B 标准给出11兆位/秒的无线以太网速度,给用户带来好处,速度能可靠地支持日常的业务应用、电子邮件、因特网和服务器网络的接入。
由3COM、LUCENT、NOKIA和其他几家有无线局域网业务的公司组成的“无线以太网兼容性联盟”支持新的标准,此标准也有望实现跨多厂商与用户团结起来的作用。
现在,厂商能专注在单一的高速标准上,用户也能以通过关注给出厂商互用性和性能。以满足他们应用要求的标准上,解决了从一大堆无线网中作选择的难题。

无线技术又称为“智能天线”(smart antenna),主要用来完成空间滤波和定位的互联网技术。接下来小编为大家整理了无线技术词汇解释,希望对你有帮助哦!
Wardriving:Wardriving is the term for finding and marking the locations and status of wireless networks. Wardrivers typically use software to determine whether the network is open or closed and a Global Position System device to record the location. A wardriver marks the spot either by using a symbol written in chalk on a building near the spot -- known as warchalking -- or mapping the locations and posting it on the Internet.
Warchalking:Warchalking is the name given to the practice of drawing symbols in public places to alert others to the location of a Wi-Fi wireless network. The symbols, typically drawn in chalk on a building, indicate whether the network is open, closed or whether it uses encryption.
WEP:WEP is short for Wired Equivalency Privacy and it is a security protocol for Wi-Fi networks. Many base stations have WEP turned off by default but users can change that setting. WEP, however, has known flaws that skilled hackers can exploit.
Wi-Fi:Wi-Fi is short for "Wireless Fidelity" and is a set of standards for wireless local area networks based on the specifications known as 802.11. It was originally developed for use by wireless devices and local networks but it is now used for Internet access as well. If you access the Internet wirelessly from your computer or personal digital assistant, chances are you are using a flavor of Wi-Fi.
Access point:An access point is the connection that ties wireless communication devices into a network. Also known as a base station, the access point is usually connected to a wired network. Most Wi-Fi networks have a range of up to 150 feet but the access point range can be extended through the use of repeaters, which can amplify the network's radio signal.
Bluejacking:Bluejacking is a practice of sending anonymous text messages to mobile users using Bluetooth. Phones that are Bluetooth-enabled can be tweaked to search for other handsets using it that will accept messages sent to them. However, a user can avoid these messages by setting their device to "invisible" or turn off Bluetooth when not using it. Bluetooth is a protocol that allows devices such as mobile phones and laptops to send data to other devices, without wires, over distances of about 30 feet.
Bluesnarfing:A security flaw in Bluetooth that could allow an attacker to access and copy information stored on a mobile phone without the user's knowledge has been dubbed "bluesnarfing." Any information stored on a phone -- like contact lists or e-mail and text messages -- are at risk in a bluesnarfing attack.
Hot spot:A hot spot is another name for a Wi-Fi access point or an area where there is an open wireless network. Typically, a hot spot has free wireless Internet access but it also applies to areas with paid access, such as coffee shops or airports.
MAC Address:A MAC address, short for Media Access Control address, is a unique code assigned to most forms of networking hardware. The address is permanently assigned to the hardware, so limiting a wireless network's access to hardware -- such as wireless cards -- is a security feature employed by closed wireless networks. But an experienced hacker -- armed with the proper tools -- can still figure out an authorized MAC address, masquerade as a legitimate address and access a closed network.
SSID: SSID is an acronym for Service Set Identifier. The SSID is a sequence of up to 32 letters or numbers that is the ID, or name, of a wireless local area network. The SSID is set by a network administrator and for open wireless networks, the SSID is broadcast to all wireless devices within range of the network access point. A closed wireless network does not broadcast the SSID, requiring users to know the SSID to access the network. Most wireless base stations come with a default SSID that is easily found on the Internet and security experts recommend changing the default SSID to protect your network.
Stumbler:A software program that looks for wireless networks and determines whether the network is open or closed. A well-known example is NetStumbler.
