New Ways to Solve Your Cell Phone Dead Spots

Ready to abandon your landline, but stymied by poor indoor cell reception? Two new technologies, one that lets you make calls over your home wireless network through your cell phone and another that uses tiny, inhome cell towers called femtocells are emerging to fill gaps in cell coverage. Both services make use of your broadband connection to route in-home cell phone calls over the Internet using VoIP, but they let you make and receive calls directly from your mobile handset, with your regular cell number. You can start a call indoors over broadband and continue it outside over cellular, and vice versa. According to early adopters, both systems are transparent to use and both function well.

Your Own Cell Tower
Sprint’s Airave system places a miniature cell tower, called a femtocell, in your house. The service is being tested in Denver, Indianapolis, and Nashville, and is set to roll out to the rest of the country in 2008. The Airave hooks up directly to your broadband router. When in range of the Airave, any Sprint handset will connect automatically to the device, which will then transmit calls over the Internet. As many as three handsets, from a pool of up to 50 registered or authorised phones, can make or receive calls simultaneously on a single femtocell. Additional callers are routed to the nearest cell tower.

Early adopted users report that hand offs between tower and femtocell work well and that call quality is excellent. Sprint charges US$15 per month per line for unlimited calling (US$30 for a family plan), in addition to US$50 for the Airave hardware.

The Home Hotspot
T-Mobile’s HotSpot@Home went nationwide this summer. It uses hybrid handsets that switch from a cellular network to Wi-Fi when you move into range of a hotspot. But built-in Wi-Fi isn’t enough, as special circuitry must perform the hand offs between the Wi-Fi and cellular networks. Only a few handsets work with the service: Nokia’s 6086, Samsung’s t409, and RIM’s newest BlackBerry Curve. And though any Wi-Fi router will work with the service, T-Mobile sells optimized models from D-Link and Linksys that promise to provide better voice quality and to extend your handset’s battery life. (Wi-Fi is a big power eater.)

How To Find Wireless Hotspots

People find hotspots in many different ways:

  • Online directories
  • Software directories
  • Display signs
  • Wi-Fi finders
  • Laptops/PDAs

People who want Internet access while traveling can find hotspots in particular areas by searching online directories. They can view pertinent details of the hotspots, such as the service set identifier (SSID), also referred to as the hotspot’s network name, and whether the network is free or fee-based. The following are a few websites offering online directories that people can use to find hotspots:

  • www.jiwire.com
  • www.wi-fihotspotlist.com
  • www.wifinder.com
  • www.hotspot-locations.com

Many of the major hotspot networks and online directories also offer a free software program that people can download and install on their computers. This allows travelers who are on the go even in the car or airport to quickly find hotspots without an Internet connection. Following are a few websites that offer offline or downloadable software directories

  • www.jiwire.com
  • www.boingo.com
  • hotspot.t-mobile.com

Many businesses and organizations display signs throughout their facility indicating that they host a public hotspot. The display of door, counter, and street signs helps notify people passing by or through the location of the Wi-Fi hotspot.

Wi-Fi finder such as Kensington WiFi Finder Plus, which provides a way for gadget lovers to find hotspots. This immediately lets someone know if a wireless network is nearby, without the hassle of the user taking out and booting up his laptop. The features and functionality of these devices differ greatly, depending on the manufacturer. Some finders notify the user of Wi-Fi networks just by illuminating a certain light. More advanced finders might have a small screen that displays important information about the detected network, such as the SSID, security level, and signal strength.

Wi-Fi finders are convenient; however, they might notify you of every wireless network nearby, not just the public hotspots. Wireless networks that are intended for private use can be secured so that the public cannot connect. Nevertheless, a good percentage of businesses and consumers do not fully understand the security risks and do not properly secure their network. If a private wireless network is not properly secured, anybody can potentially connect and access the Internet and files on the network. Thus, some people think that just because they can connect to a network, it is a hotspot and it is open to the public. Instead, some of these Wi-Fi networks belong to private citizens and businesses. They might not be intended for public use and might even be unlawful to use.

Many people find Wi-Fi hotspots simply by booting up their laptop or PDA and viewing the available wireless networks in the area. This also brings up the issue that some networks might not be intended for public use. Users should look for networks that are clearly identified for public use.

Wi-Fi Hot Zones

Wi-Fi hot zones, also known as Wi-Fi clouds, provide public Internet access, just like hotspots, but they cover a larger area and they are typically for use outdoors. These hot zones might cover anywhere from a city block to an entire city, commonly referred to as a muni or municipal network, or even a whole county.

Even though end users in these hot zones connect using Wi-Fi, these systems typically use a different design approach, called mesh networking, instead of the traditional wireless LAN infrastructure, such as in Wi-Fi hotspots.

Along with giving citizens and visitors convenient Internet access, these wireless networks might provide a concurrent private network and Internet connections over the same system. Companies might be able to purchase a secure Internet connection for their business, and government departments could support communication services such as parking and utility meters and city cameras.

More and more cities are hopping on the muni Wi-Fi bandwagon, trying to keep up with the digital world and wanting to attract people and businesses to their area.

These hot zones are convenient, allowing people to check their e-mail and browse the Internet pretty much anywhere outdoors within the coverage area. In some cases, users can even access the Internet in moving vehicles, where traditional hotspots do not cover.

Hotspot Connectivity Everywhere

Wi-Fi hotspots bridge the Wi-Fi connectivity gap between wireless networks in homes and businesses. People can access e-mail and other online services between home and work or while traveling. This allows them to keep up with customers, associates, and family members.

Wi-Fi hotspots are found in many public places where people might want to pop open their laptop and browse the Internet. Following are some typical places where you might find a Wi-Fi hotspot:

  • Cafés, restaurants, and bars
  • Hotels, conventions centre
  • Bookstores and libraries
  • Office building reception areas
  • Airports, Bus Terminal, Train Stations
  • Clubs and organizations

Cafés and restaurants provide wireless Internet access for customers while they are enjoying their food and beverages. Along with other businesses and organizations, cafés and restaurants will likely benefit with more foot traffic to their location when they provide this convenient Internet service to customers and visitors.

A majority of travelers these days choose only hotels that provide broadband Internet access within the rooms. This lets people keep in touch with their office while they are out of town. Some hotels provide a wired Internet connection usually an Ethernet or data port. Ethernet provides broadband Internet access similar to Wi-Fi, but Ethernet requires a cable to connect the user laptop to the network. This restricts the user to a single location in the room usually a desk. In addition, most hotels provide a data port on the telephone for dialup modem users to plug into. This also requires a restrictive cable connection, and the performance is slow and unusable for some websites and e-mail attachment downloads.

Even though wired Internet connections are widely available, most people prefer Wi-Fi Internet access. This enables guests to move about the hotel and still be connected to the Internet. For example, a business traveler can use the Internet from anywhere within the room, such as from the desk or while relaxing on the bed. In addition, this person can go down to the bar or lobby and still have Internet access. A Wi-Fi network in a hotel also becomes useful when one or more people with laptops are staying in the same room, because wired connections allow only one person at a time to use the Internet.

Students, business people, and others typically use Wi-Fi hotspots at local bookstores and libraries while working on homework or work-related tasks. Bookstores typically did not have Internet access before they began offering Wi-Fi access. For years, libraries have had computer workstations connected to the Internet for public use.

Yet offering Wi-Fi Internet access helps eliminate some costs, enables more people to use the Internet at once, and lets users move about the building while using Internet applications.

Corporations in the past did not have Internet access available for visitors throughout their office buildings because of the difficulties in allocating a wired connection. In most cases, an unused wired Ethernet port is not available or is in a physical location where it is not practical for the visitor to access it. An open port, for example, could be located on the wall within the conference room. Regularly scheduled meetings in the conference room would likely get in the way of the visitor using the room to use the network connection. Visitors such as salespeople, customers, and consultants, though, can definitely benefit from Wi-Fi Internet access while inside the facility, even if the wireless network is made available only from specific places, such as the company lobby, and kept separate from the corporate network.

Wi-Fi Internet access within airports enables travelers to send and receive e-mail and conduct other necessary tasks while traveling. This is useful during long waiting between flights and unscheduled delays or cancellations. Many airports today still have not installed wireless hotspots. Given that airports can be extremely large, this could be an expensive task for the airport authorities. However, even installing a small hotspot within specific restaurants, airline clubs, or concourses of the airport would be useful to travelers.

Wi-Fi access is also available while onboard aircraft during some international airline flights, but limited to some airlines or selected routes. When Internet access on airplanes becomes widely accepted, many people will benefit, especially during longer flights. Business travelers will certainly be more productive if they can correspond via e-mail and use Internet-based applications while they are restricted to an airplane seat.
