In developed markets where the foundation of a high-capacity data transmission network exists, WiFi overlays are likely to be very effective. In emerging economies, where the foundation is yet being built, the same solutions may not as effective. But it is worth following the action, described in the NYT article below.
“Google has deployed 380 lamppost-mounted Wi-Fi transceivers in Mountain View to make wireless Internet service available to anyone who has registered for a Google account, which is free. The company has invested a significant amount in promoting the benefits of wireless Internet access. It has held a series of tutorials, one of them drawing 750 residents.
Users will be limited to one-megabit data rates for both uploading and downloading information, somewhat slower than digital subscriber line (D.S.L.) service offered by phone companies. But Google has experimented with data rates above eight megabits, and Mr. Sacca said the company would consider increasing bandwidth after it had more experience with customer demand.
Making use of the service within a home in Mountain View typically requires a device called a Wi-Fi repeater, which costs $30 to $170. The repeater amplifies the wireless signal and relays it to individual computers equipped with a Wi-Fi card or Ethernet connection.
The installation, in a city of 72,000 residents, cost roughly $1 million, an amount that Mr. Sacca said demonstrated the low barriers to deploying such a service.”
