Earthlink is dropping its citywide Wi-Fi
Earthlink is dropping its citywide Wi-Fi project in Philadelphia. The network had many glitches and few subscribers. No one agreed to buy the network, so Earthlink will dismantle it. It is discontinuing its municipal Wi-Fi projects across U.S.A.

Roam seamlessly between WiMAX and Wi-Fi network
Green Packet Berhad, developer of next-generation mobile broadband and networking solutions and GCT Semiconductor, a supplier of mobile WiMAX solutions to the global market, have announced collaboration to bring the world’s first intelligent connection management solution. This solution is expected to provide connectivity and handover between WiMAX and Wi-Fi.
Malaysia’s first and largest WiMAX operator, Packet One Networks Sdn Bhd, has already been signed by Green Packet, which has its headquarters in Kuala Lumpur. Green Packet will look to roll out this new and innovative technology in Malaysia.
GCT’s GDM7215 single-chip WiMAX plus Wi-Fi integrated circuit offers benefits such as a physically smaller solution, lower power consumption and reduced bill-of-materials. Users can roam seamlessly between WiMAX and WiFi networks and create a robust and highly-desirable wireless broadband experience.

Data transfer speed of WiMAX technology for end users
Users can expect to have broadband access speeds ranging from 1-5 Mbps depending on the service provider offering.
When the WiMAX Forum refers to 40 Mbps, it is referring to a single channel in wireless frequency (as part of the network) that is likely shared among multiple users. Individual users will have access to that amount of capacity, but the likelihood is they will have the ability to achieve downlink speeds of 1-5 Mbps, which is similar to the cable experience. There is the potential to burst to higher speeds, but that would depend on the operator's plans and business model, frequency being used, distance of the user from the base station or node, whether there is line of site or NLoS to the base station, and the number of users on the network.
A single WiMAX base station or node should be able to serve thousands of subscribers. The actual number of users will depend on the guaranteed bandwidth to each users and the actual spectrum used by the operator.

What is Wi-Fi?
Wi-Fi, Wireless Fidelity, is way to get Internet access and used to define any of the wireless technology in the IEEE 802.11 specification - including (but not necessarily limited to) the wireless protocols 802.11a, 802.11b, and 802.11g.
The Wi-Fi Alliance is the body responsible for promoting the term and its association with various wireless technology standards. is meant to be used generically when referring of any type of 802.11 network.
Any products tested and approved as "Wi-Fi Certified" (a registered trademark) by the Wi-Fi Alliance are certified as interoperable with each other, even if they are from different manufacturers.
The Wi-Fi Alliance began as a community aiming to address the needs of consumers by ensuring products from different vendors working well together. The Alliance created the branding "Wi-Fi Certified" to reassure consumers that products will interoperate with other products displaying the same branding.
However, any Wi-Fi product using the same radio frequency (for example, 2.4GHz for 802.11b, 802.11g, 5GHz for 802.11a) will work with any other, even if not "Wi-Fi Certified."
A Wi-Fi enabled device can connect to the Internet when within range of a wireless network connected to the Internet. The coverage of one or more interconnected access points — called a hotspot — can comprise an area as small as a single room with wireless-opaque walls or as large as many square miles covered by overlapping access points.
Wi-Fi also allows connectivity in peer-to-peer (wireless ad-hoc network) mode, which enables devices to connect directly with each other. This connectivity mode can prove useful in consumer electronics and gaming applications.
Wi-Fi technology boasts fast data transfer speeds and range, making it a good replacement for Ethernet (802.3) systems.
