AT&T <strike>Grants</strike> Denies Us Mobile VoIP Freedom

October 12, 2009

The big news last week was how AT&T grants denies us mobile VoIP freedom. Just last week I wrote how AT&T had "granted" us mobile VoIP freedom by finally allowing SIP port 5060 on their 3G data network. I was able to use siphon, a SIP-based application on my jailbroken iPhone to register with TMC's IP-PBX and make/receive phone calls.

Well apparently, AT&T must read my blog or something, because once again SIP port 5060 is blocked. I tried siphon on my iPhone this morning and now it won't register.

Vonage Launches Vonage Mobile for Apple iPhone & Blackberry

October 5, 2009

Today Vonage launched Vonage Mobile for the Apple iPhone and Blackberry. I've already said this will be a killer app and could sway iPhone users to sign up with Vonage. Though, many iPhone users and wireless phone users in general have killed their landline entirely. Nevertheless, there are some cool features with Vonage Mobile, including a single-number identity for both your home and mobile number that could give Vonage an added boost.

Vonage World is not limited to just WiFi - it works over 3G!  Vonage Mobile offers low-cost international calling and Vonage claims that you can save more than 50% on calls to dozens of countries versus the rates charged by wireless carriers.

Rich Takes xMax Wireless for a Test Drive

September 29, 2009

Rich Tehrani took xG Technology's xMax technology, a WiMAX / LTE competitor for a (literal) test drive.

Rich writes:

xG Technology proclaimed in 2005 that they have a revolutionary technology which allows wireless broadband using unlicensed and licensed frequencies. They said they could build the equivalent to a WiMAX network without the need to spend a massive amount on spectrum auctions and moreover, their technology had better range than WiMAX.

It seemed too good to be true and after some years of waiting, the communications industry got impatient. After all, this revolutionary technology had the potential to change the way wireless networks are deployed. If it was real, where was it?





Livestream Livepack Bonds Six 3G/EVDO modems for Ludicrous Wireless Internet Speed!

September 24, 2009

Livestream today is launching the world's first solution for wireless live streaming at HD quality by bonding six load-balanced 3G/EVDO modems over three carriers. Called Livepack, this unique solution enables you to have a roaming live video studio anywhere you can get 3G/EVDO connectivity. Livestream says it can stream HD video at far lower costs than traditional solutions such as broadcast trucks.

 Of course, bonding six 3G/EVDO modems together has some other fringe benefits - like ludicrous wireless Internet speed! Wonder if you can tether the Livepack to your laptop and get super high-speed Internet access while on the road?

FCC Proposes Applying Net Neutrality to Carriers' Wireless Networks

September 21, 2009

Today, FCC Chairman Julius Genachowsk said that wireless carriers shouldn't be allowed to block certain types of Internet traffic flowing over their networks. This has huge implications for the VoIP industry, since as I wrote last week, AT&T blocks port 5060 (SIP) on their 3G data network, thus blocking VoIP applications. If the FCC mandates that the wireless carriers can no longer block applications on their data network, this opens up the entire 3G/4G wireless network to game-changing VoIP applications!

This will no doubt cause a firestorm of protests from the wireless industry which has invested billions in their wireless infrastructure and they see VoIP as something that will cannibalize their revenue stream. According to Yahoo, "FCC Chairman Julius Genachowski said wireless carriers should be subject to the same "open Internet" rules that the agency has begun to apply to home broadband providers."

Genachowski wants to take the same principles the FCC has already been applying to wired Internet trafficand extend them to wireless.



JAJAH@call - Twitter meets the Phone

September 17, 2009

JAJAH, today announced the beta‐launch of its Twitter calling solution, JAJAH@call. JAJAH users with a Twitter account can make phone calls via Twitter free of charge. @calls are made without revealing your number and without needing to know the number of the person you wish to call - all you need is their Twitter username. The key caveat being BOTH users must be JAJAH users (to do the mapping between Twitter and your phone number)

So how does it work?

To make a call you simply send a Twitter message (tweet) with "@call @username" where the 'username' is the Twitter name of the person you wish to call.



Siphon SIP App for iPhone Works over AT&T's 3G network? Holy Toledo!

September 17, 2009

I tested Siphon, a SIP-based VoIP application for the iPhone, in California at ITEXPO. Interestingly, Siphon worked perfectly in California over AT&T's 3G data network. Yes, you read that right - VoIP over 3G! I couldn't contain my giddiness when I realized I could now register my iPhone with TMC's Asterisk-based IP-PBX and make/receive calls.

802.3at-2009 Power over Ethernet (PoE) Plus Standard Ratified

September 14, 2009

The IEEE recently ratified 802.3at, a new Power over Ethernet Plus standard. The IEEE 802.3at-2009 Power over Ethernet (PoE) Plus standard defines the technology for powering a wide range of powered devices at up to 25W over existing CAT5e and above cables.

Mike McCormack, Chair of the IEEE P802.3at Task Force said, "IEEE 802.3at uses the Link Layer Discover Protocol (LLPD) from IEEE Std 802.1AB, which allows dynamic power allocation and negotiation down to 1/10th of a Watt, and associated technology including Type, Length, Values (TLVs) from IEEE 802.3bc, which was also recently approved. This will allow equipment manufactures to manage their power supply costs and efficiencies at levels not possible with previous standards, and to cut their costs in the process."

I contacted Daniel Feldman, Director of Marketing, Telecom, Microsemi and he responded to Mike's quote by saying, "This is a mis-interpretation of what can be actually done. All LLDP allows is for more devices to be powered with a given power supply, it does not increase the power supply efficiency in any way."

Mike McCormack also stated,  "In addition, we have increased available power up to 25W.





D2 Technologies Showcases its mCUE Converged Communications Client with Embedded VoIP for Android at OESF Japan

July 28, 2009

Some interesting news from D2 Technologies about them showcasing their mCUE™ converged communications client with embedded VoIP for Android at OESF Japan. I should point out that D2's mCUE mobile convergence software solution combines a communications user interface with the company's vPort MP VoIP software platform and is targeted towards OEMs and service providers to help deliver integrated Fixed Mobile Convergence (FMC) and Unified Communications (UC) functionality.

At OESF they will demo how mCUE can enable VoIP, video chat and other IP communications capabilities in stationary Android-based embedded equipment and consumer electronics devices. With mCUE, these devices can offer premium multi-service unified communications capabilities and deliver simultaneous interoperability with any communication service provider, Instant Messaging (IM) community or social networking platform. All popular communication modes are converged to a single communications user interface (UI), including circuit switched voice (PSTN or cellular), VoIP, Instant Messaging (IM), SMS and video chat.
