Wi-Fi service symbolizes the technology that allows information to travel in the air. WiFi service is part of the ever expanding and interrelated community. The idea of staying ‘connected’ without glitches throughout the day has been realized through Wi-Fi connection. Walk into public places like café, multiplex or even business convention centers and hotels, online surfing has become hassle free due to Wi-Fi network. Besides being unobtrusive, Wi-Fi internet is also inexpensive and easier to set up. Wi-Fi router allows laptops, smartphones, Tablets et al to access within the Wi-Fi internet connection premises. Besides, new users can join the network at zero incremental cost.
Wi-Fi networking use radio waves to transmit the data. The Wi-Fi connection adapter in the laptop or computer transmits data via radio signal. The signal from the Wi-Fi service provider is received and decoded and send forward to the Internet using the Ethernet. The entire procedure also works on the reverse mode too. The router also receives information from the Internet and translates it into a radio signal. The radio wave is sent to the wireless adapter. Basically, these networks are made up of cells that provide coverage across the network.
The technique is similar to the one in walkie-talkies used for security purposes, mobile phones et al. In the present scenario, the 802.11 standards mainly focus on specific applications of wireless networks, like wide area networks (WANs) inside vehicles or technology which allows the user to move from one wireless network to another. Transmitting takes place at the frequencies of 2.4 GHz or more which is generally higher than the one used for the mobile phones, TVs or even walkie-talkies. Higher frequencies allow more data transmission. Usually the 802.11a transmits at 5 GHz and uses orthogonal frequency-division multiplexing (OFDM) as coding technique. The radio wave splits into sub-signals and hence, reduces interference. As compared to 802.11a, 802.11b is more pocket friendly and popular among users. Comparatively, the latter one transmits in 2.4 GHz. It uses the complementary code keying (CCK) modulation for efficiency.
Thumbs Up for Wi-Fi
Four components of high speed access, network gateway, wireless local area network and wireless customers have worked towards WiFi internet’s demand in the global market. Wire free and hence, hassle free is the top notch advantage of Wi-Fi LAN services. In the present situation of ‘staying connected’ hoopla, Wireless internet connection has emerged out as a popular choice in the corporate houses, hospitals, convention centers, universities, hotels, bistro et al. All one needs is a laptop and the right spot. These days, laptops come up with in-built Wi-Fi card. Instead of getting wired at home or office with Local area network, users enjoy the ‘no-restriction’ approach. For the professionals who travel throughout the year, Wi-Fi connection is a boon. Wi-Fi broadband allows the users to enjoy the Internet in the public. Users can access the Wi-Fi service while on roaming too. There are numerous Wi-Fi access points and network interfaces which supports various degrees of encryption to protect traffic from interception.
Another major advantage is the ability for 802.11b and 802.g to frequency hop. It allows both cards to transmit themselves on three bands. Wi-Fi alliance allows uninterrupted service by testing the interoperability of WLAN products. The idea is to keep the working procedure strictly on the IEE 802.11 specifications.
D2V ISP is launching citywide Wi-Fi access. Keeping in mind the city-centric problem, where concrete walls diminish Wi-Fi signals, here Wi-Fi modem from consumer wireless equipment are designed to connect with Access Points within the radius. Laptop or cell phone users will be using a D2V wireless adapter which will convert the request into a radio signal and broadcasts it in the air. D2V Wi-Fi device/Omni Access Point picks up the signal and translates it back into its original form. The access point passes on the request to the base station. The D2V Wi-Fi base station which is connected through internet returns the requested information to the access point of D2V Wi-Fi OMNI tower across the same connection. Later, the OMNI tower converts the information into a radio signal and broadcasts it into the air. D2V’s USB dongle receives the information.
D2V Wi-Fi internet service assures to provide cost-effective coverage and the capacity to meet the quality required by mobile data users in the state. D2V’s Wi-Fi network service focus mainly on intelligent access points for wider coverage. After sweeping the major cities like Vadodara, Ahmedabad with high-quality internet service, D2V Wi-Fi will provide a platform for delivering new services like citywide WiFi.
• Value and convenience for D2V ISP users.
• D2V Wi-Fi provides connectivity without disturbing the regular functions.
• Downloading, sending emails, online radio et al at sky-scraping speed.
• Users can access the laptops while on the move within the radius of nodes.
