WiFi Basics Part 1 – Frequencies and Channels

Tuesday, March 10th, 2015

This is news to me. I never realized that wireless frequencies were set aside way back in 1947. In addition to that fun fact, the article also provides a helpful overview of wireless communication in general.

In 1947, the International Telecommunication Union (ITU), a UN agency, designated certain bands of the RF spectrum as ISM. The idea was to have an international standard of frequencies that were reserved for Industrial, Scientific, and Medical equipment. Ironically, telecommunications was not the original purpose.


WiFi Map Pro Passwords Reveals Open Wireless Hotspots

Thursday, January 29th, 2015

This sounds like a pretty useful app … providing that other users in your service area have gone to the trouble of registering a few local wireless hotspots.

You have two core options to connect to the Internet with your smartphone or mobile device: WiFi or using mobile connections. Both systems have their advantages and disadvantages. While you may run into privacy issues while using wireless connections that you don’t have full control over, mobile connections are often limited bandwidth-wise which means that you may increase your mobile bill using them or limit the connectivity options once you hit a certain threshold.


Using a Dual Ethernet Console Server in a Wireless Network Application

Tuesday, August 5th, 2014

In addition to serving as a vital element in network redundancy applications, a Dual Ethernet Console server can also help to provide wireless access to inaccessible network elements in lights out data centers and locked equipment cabinets. This type of implementation is particularly helpful in server rooms and other situations where tech support “crash carts” are used to provide quick access to vital network elements during emergencies and outages.


You May Soon Need to Install a Thermostat or Fridge Adblocker

Wednesday, May 21st, 2014

This article provides a perfect explanation as to why I’ll never buy Google Glasses or a Chromebook …

Ads, they are everywhere on the Internet, on television, radio, on the street and in magazines. One safe haven remains, and that is your home, provided that you are not browsing the Internet, watching TV, listening to radio or reading magazines. That’s about to change though if Google gets its way. In a letter to the Securities and Exchange Commission, sent in December but disclosed yesterday, it confirmed that it had plans to bring advertisement to “refrigerators, car dashboards, thermostats, glasses, watches” and other devices and locations a few years from now.


Types of Wi-Fi Encryption You Can Use

Thursday, September 22nd, 2011

This is a nice, concise, side-by-side comparison of the most popular wi-fi encryption standards …

There are many types of Wi-Fi encryption you can use on modern Internet routers. So which one should you use? Many people don’t even use encryption, and those that do just pick an encryption type at random without knowing what they do. Most encryption types are better than nothing at all, but some are more suitable than others.

Here’s a useful tip for those of us who own wireless routers …

Setting up a wireless network can be a hassle. You need to remember the security key and tediously type it correctly for all devices on your network.

Looking Beyond Coffee, Starbucks Seeks a New Digital Future

Monday, June 14th, 2010

This seems like a great way to draw customers … plus the ability to custom tailor content for their users is a nice marketing trick too.

Starbucks today announced that it will provide free wireless access in all U.S. company-operated locations starting July 1. And this fall it will launch the Starbucks Digital Network, a partnership with Yahoo that will provide customers free unrestricted access to pay sites such as the Wall Street Journal. Additional content providers in the new, in-store network offering include iTunes, The New York Times, Patch, USA TODAY and ZAGAT.


Telcos Begin Monetizing Your Wireless Location Data – Your movement data is the next cash cow

Friday, May 28th, 2010

And some day, they’ll figure out a way to insert advertisements into our dreams …

Slashdot directs our attention to the fact that wireless carriers are just starting to realize they can monetize all matter of data collected from mobile users — specifically data that highlights their movement habits. According to MIT Technology Review, researchers and marketers are finding plenty of new uses for call detail records, or CDRs — which allow them to study a mountain of user behavior data. That data can be used by researchers or city planners to study travel behavior — but it’s likely going to be a gold mine on the marketing behavioral front:


Your ISP And Your Router Want To Hit You With Redirection Ads – Users note that Cisco ‘feature’ still annoys…

Friday, May 21st, 2010

If you’ve been getting redirected to a lot of strange, ad-filled pages lately, this might explain why …

Of course the majority of large ISPs now engage in DNS redirection advertisement, which creates a new revenue stream for ISPs by redirecting users to an ad-laden search portal instead of a 404 when they enter a misspelled or nonexistent URL. Now users in our Linksys forum note that some Linksys-branded routers are hijacking user 404s and redirecting users to a Yahoo ad portal before their ISP even gets the chance. Fortunately it looks like the “feature” can be disabled, only comes in certain models — and of course you can always install third-party custom firmware — which often provides more functionality anyway. Update: Or not. User uid://1458205 writes in annoyed:


FCC Unable/Unwilling To Conclude Wireless Industry Uncompetitive – Despite their own study that supposedly suggests as much…

Friday, May 21st, 2010

It’s always nice to see our tax dollars hard at work …

The FCC has released their fourteenth annual report (pdf) and like most things the FCC has attempted recently, the report tries to carefully walk a center line to avoid upsetting anyone. The report insists that the wireless industry is not “effectively competitive,” then proceeds to insist that the FCC is not making any conclusions on whether the wireless industry is competitive. In a statement (pdf), FCC boss Julius Genachowski said the agency did “not seek to reach an overly simple ‘yes-or-no’ conclusion” about the state of competition. The wireless industry expressed disappointment at the agency’s unwillingness to gush:
