DECT vs. Wi-Fi Death Match…Who Will Be Victorious?

Today I am talking about DECT and Wi-Fi Technologies, and who I think will win out in the end in an endless battle for supremacy. This idea came about after reading a article (SNOM Brings m3 DECT Phone to U.S.). The article shows that DECT is a technology that has worked well in the European market, and that it is just now starting to hit the U.S.

DECT (Digital Enhanced Cordless Telecommunications) uses base stations and SIP (Session Initiated Protocol) to connect to your VoIP PBX. Think of it this way; your cordless phone at home has a similar base station to charge and receive signals to talk to your old analog phone lines. The technology works pretty much the same way, but instead of an analog signal it’s using digital to talk to a VoIP phone system. Pretty easy to understand that way. Now, expand on that thought and think about multiple phones on one base station. That is what this technology is giving the digital world.

Then there is Wi-Fi. Good ol’ Wi-Fi. What isn’t there to love about wireless signals that can be used to talk to computers, phones, and other goodies?  With Wireless VoIP technology you have an access point, or a “Hot Spot” (like Starbucks) and access to the World Wide Web. That too is pretty easy to understand.

Now that you have a very basic understanding of the concepts that run both DECT and Wi-Fi you should also understand the cons of such technology.

DECT runs on 1880 MHz-1900 MHz to where as Wi-Fi runs on 2.4 GHz. What does that mean you ask? Well because DECT runs on a different frequency than traditional Wi-Fi, you will get no interference on your cell phone, computer or anything else that needs the Wi-Fi frequency for broadcasting. Also, if you have too many applications on a Wi-Fi network you may start to see a decline in QoS (Quality of Service) on some or all of the products on your Wi-Fi network. (WINNER = DECT)

And there is also battery life to consider. DECT, because of its lower frequency and better batteries has an amazing life. To where as Wi-Fi Phones do not. For example, Spectralink Kirk DECT phones have a 20-hour talk time and a 200-hour standby time. That’s right; there is no typo in what I just wrote. Or you can go with Wi-Fi and have (if you’re lucky) a three-hour talk time and a 50-hour standby time. And that is with the Linksys WIP 330 to which is one of the better phones on the market. (WINNER = DECT)

To wrap this up we need to look at access points and the base stations. These are the backbone of any network, and these are how the units get the information needed to communicate to an IP PBX. Wi-Fi has an easy to set up wireless access point, such as the Linksys Wireless routers. They are cheap, and very easy to setup. Then there is the base station for the DECT phones. Not as easy to setup, but still pretty simple; I would estimate about double the amount of time taken with Wi-Fi access point will be taken on the base station, and also they are not as cheap.

A typical Wi-Fi station setup will cost $69.95 to $165 for a Linksys Wireless router and another $210 for the WIP 330 unit, Total being in the range of $270 to $350.

For a Polycom DECT, setup will cost $344.99 for the Base station (Called Server 500) then another $414.99 for the KIRK 5020 Phone.

Snom has a bundle package available called M3 for $244.99 that comes with one phone and the base station. This can hold up to eight phones on the same base station.

So, if price is your biggest concern then I would call Wi-Fi the winner, if it’s not, and you want a nice system that is reliable, and doesn’t interfere with your current wireless network, then I would say DECT wins. (WINNER= DRAW).

Spitting is a Dirty Habit

May 21, 2008 by Garrett Smith

Spit = Spam over Internet protocol.

Who knew?

I’ve heard everything from Spam to Phishing to Vishing to Chicken Scratch.  Next up in the hacker field could be VoIP technology, or so Mr. William Jackson says from Government Computer News.

I recently came across this article from a Twitter follower; “Careful with that call: It’s only a matter of time until IP telephony is hit by spam and malware.” It was an interesting look at the possible vulnerabilities in VoIP technology, but also an excellent look at the cautionary steps already in place to protect VoIP users from spam, spit and other annoyances.

VoIPshield Systems, founded in 2005, works on researching these technicalities and developing patches and solutions before they reach the marketplace.  IBM Internet Security Systems (IBM ISS) also does similar work, and doesn’t want to alarm the public, but like with any invention or business model, they just want to be prepared for the ‘what if.’

No method of technology or telecoms is perfect, whether it be PSTN, mobile, VoIP, the iPod, HDTV, hybrid cars, etc.  Technology continues to grow and change and improve over the years.  Look at how many years the automobile has been around.  Frankly, there are still MANY ways to improve there.  Only in the past five years or so has the general public grown to accept broadband Internet into their homes.  And how many people complain that the iPhone is just too slow for Internet browsing?  Sure enough, a new model will be coming out in the next year.

It’s nice to know that the big guys are looking out for VoIP users and not accepting the status quo of the technology.   It displays not a fear for the potential problem, but a concern for the customer, and an investment in their future.

Are you worried about spit? What will this do for the telecom industry?  Think about it. Spam in your email isn’t that scary.  You just have to hit the delete button.

Job Coaching from Tim Berners-Lee

GigaOm mentions an upcoming interactive “round table” discussion being hosted by Rensselaer Polytechnic Institute on June 11th called Tetherless World Research Constellation. The panel is comprised of academic and industry luminaries.

The cool part….rather than sit at your computer and listen to these MENSA members wax philosophical about the world wide web, you can register as a remote attendee, and submit a question of your choosing. User submitted questions then go through a peer voting process, and the top questions will be fielded by the panel. This has probably been done before, but I thought it was cool and worth mentioning.

One of the esteemed panelists is Tim Berners-Lee, whom you probably have heard of if you don’t live in a bomb shelter. Tim is credited as the inventor of the world wide web (Not George Bush, nor Al Gore)….which is pretty hard to trump. Talk about a feather in your cap. In this web-centric world of ours where everyone has instant access to pretty much everything, I imagine Tim can pretty much write his own ticket….I’d love to be a fly on the wall at an interview where Mr. Berners-Lee is applying for a job.

IPCS Word(s) of the Day: Dome Camera

Dome Camera = A type of camera with a dome-like shape. Some come with infrared lighting and some are designed to be tamper-proof. Dome cameras can be analog or IP, fixed, Pan/Tilt or full PTZ. Dome cameras are typically ceiling-mounted or placed under an overhang, but can occasionally be wall mounted depending upon your particular application.

What Do You Know About TBCS?

May 20, 2008 by Garrett Smith

In the telecom industry, new products, ideas, and companies seem to come and go like the wind, but one thing remains constant-Tennessee Business Communication Services. “TBCS” is proud to celebrate its 30th anniversary in 2008. As a proud component (meaning VoIP Supply) of the growing success story behind TBCS, I personally want to put them on a pedestal for the general public.  In hopes of continual growth through the Midwestern states, TBCS has definitely made its mark in a very competitive telecom industry.  Having ties to the local Tennessee community, as a Western Kentucky University graduate, this company has won my interest and dedication fully.  I take pride in their core competency which has roots deeper than most “one hitter quitter” telecom companies.  A proven track record, along with superior telecom knowledge, has set the standard for local telecom installers.

While technology has changed significantly over the years, TBCS’s dedication to customer support has never wavered. Whether it’s a 20-year-old key system (which TBCS still has several under support) or a brand new IP PBX, these daily calls for support are greeted by a friendly live voice and responded to by a courteous local technician. TALK ABOUT CUSTOMER SERVICE!!  As a TBCS customer, you can also expect a direct relationship with a personal account manager who will drop by from time to time and physically inspect how things are going.  The majority of TBCS’s competitors consider this level of service to be “old fashioned,” but TBCS’s customers wouldn’t have it any other way.  VoIP Supply has laid the benchmark throughout the telecom industry for superior customer service; I’m more than honored to see our customer base follow the same “brick road” to success.

TBCS, Inc. is a Nashville, Tenn. based company that began in 1978 and is formerly known as Nashville Telecom.   In 1983, the name was changed to Tennessee Business Communication Services and in recent years has become known simply as “TBCS.” President and Founder Larry Featherstone, along with General Manager Steve Mars, have been on board since day one and continue to stay passionately committed in the day-to-day successes of an ever-growing company.   In addition to these dedicated individuals stands the General Sales Manager, Sean Wilder.  Sean is a “Go Getter” and will be sure to assist, comfort, and inform you on questions that may hold up your transition to a new telephony system.

TBCS has strategic partnerships with some of the most innovative companies in the world, including Vertical Communications/Vodavi, Win Communications, Adtran, Fonality, and TalkSwitch. TBCS also offers support agreements for a variety of other manufacturers, which you’re just a call away from finding out.

Zaptel – Who’s your DAHDI?

Digium announced yesterday that due to trademark issues, they will be renaming “Zaptel” to “DAHDI”, which stands for “Digium Asterisk Hardware Device Interface”.

Zaptel Digium Asterisk DAHDI

Zaptel is an OSS hardware driver API developed by Jim Dixon. Zaptel drivers were initially developed for BSD and Tormenta T1 interface cards. Digium began producing TDM interface cards based upon Jim’s work and made significant improvements to Zaptel on the Linux platform.

For those of you who are unfamiliar with Jim Dixon, here is his bio from the 2005 Astricon conference:

Jim is the inventor of the Zapata telephony cards and a Systems Engineer (consultant) with the main specialites in Telecom. He’s been doing Engineering ever since Junior High school (although professionally since High school) and have been an Internet developer since 1980 (working on the Arpanet for MIT). He never bothered with college.

In addition Jim have been helping with the development of Asterisk during its lifetime. He has also created and been working on the app_rpt Asterisk 2 way radio project.

Jim’s Zapata Telephony Project took its name from the historic Mexican revolutionary figure Emiliano Zapata, an homage to symbolize the revolutionary nature of the Zaptel project. The term “Zaptel” is in fact trademarked by this calling card company, prompting Digium to adopt a new name to avoid legal issues surrounding the use of the Zaptel name.

IPCS Word(s) of the Day: Digital Zoom

Digital Zoom = Digital zoom is not really zoom, in the strictest definition of the term.  What digital zoom does is enlarge a portion of the image, thus ‘simulating’ optical zoom.  In other words, the camera crops a portion of the image and then enlarges it back to size.  In so doing, you lose image quality.  If you’ve been regularly using digital zoom and wondered why your images did not look that great, now you know.

Good Ideas Lost

May 19, 2008 by Ben Sayers

As with many of my blog entries, the intended audience is just as much my staff as anyone working elsewhere and is not necessarily focused on the VoIP industry as much as it is general business, entrepreneurship and effective management. Please comment with the intention of improving the idea and providing additional value and insight.

At VoIP Supply, we are not a large company by any means, but large enough to have a layer of management between the executive layer and the departmental team members. While sometimes this layer of management is a bridge for the staff to reach out to the owners with ideas and suggestions, often times it is a dam preventing ideas from reaching the surface for a variety of reasons.

Often times the management layer uses its insight into the big picture to filter out ideas that do not mesh with the business direction and needs while at other times the ideas may not fit well with the agenda of the individual manager that it is presented to. Still other ideas are not presented in a manner compelling enough to make it to the top and therefore never receive their intended audience.

While it is in many ways the responsibility of the management team to push up staff ideas just as it is their responsibility to push down executive decisions and requests, it is also the responsibility of the team member to push their ideas and suggestions until they receive sufficient feedback indicating either that the idea has been pushed up or it was not pushed up for a particular and valid reason.

Make the wheel squeak–the loudest one is usually heard first and either oiled (implemented) or thrown out with valid reasoning and justification.

The take away: do not assume that because you had a good idea and presented it to your manager that it was heard, fully understood and moved up the chain, adequately re-presented to the company executives. As often as it is, it is not. I, though perhaps not like everyone else, enjoy hearing from staff members directly when it comes to their ideas and suggestions. Bringing an idea directly to the executive team is highly encouraged and the squashing of such action by my management is highly discouraged regardless of the intent to not waste my time or shield me from something that does not fit the needs and direction of the business. Even if the idea is not a good fit at the time, the value to me and the increased value of the employee comes by way of simply having an idea and presenting it well.

My door is open to anyone at any time. Your ideas are valuable and I’ll decide if it is a good fit for the business now or in the future. This statement is true for employees, customers, vendors, partners and the like.

Jangl and LiveUniverse a Perfect Fit?

Over the last two weeks, rumors have swirled around the industry as to the fate of the once promising voice start-up Jangl, who looked to be in shambles after running out of cash and seeing the departure of their co-founders and engineering team to JAJAH. For those of you not familiar with Jangl, they are a voice 2.0 company with a variety of web-based calling solutions, most notably their “blind” calling service that allows online dating participants to make calls between one another without revealing their true phone number.

This weekend, it was announced that Jangl had been acquired by LiveUniverse, a video, social networking and music media company headed by MySpace founder Brad Greenspan. LiveUniverse, which touts over 55m visitors a month across all of their properties, already has the following and the brand advertisers that Jangl desperately needs in order to be a profitable stand-alone business.

Fortunately for those left at Jangl and LiveUniverse, it does not appear that Jangl will necessarily be a standalone play. Although it certainly has the potential to be a stand-alone business, Jangl has had most of it’s success as a “white label” provider of voice functionality for online dating sites and social networks. The most logical next step for the LiveUniverse is to integrate Jangl’s technology across their web properties making this acquisition more about purchasing a piece of technology, rather than a business.

Next to integrating the technology across their properties, LiveUniverse would be smart to continue to try and attract more social networks and online dating sites as white label customers of their voice capabilities. The downfall of this, however, is that voice is still not a demand feature for the users of said sites. So is the marriage of LiveUniverse and Jangl a perfect fit? I think so, although I believe that it is a perfect fit because the Jangl technology compliments LiveUniverse’s current offerings and enhances the features that the company can offer to their web “guests.” I doubt, though, that the acquisition will do much for the company by way of direct revenues.
