Why is the 700 MHz hot?


It is hot because the payback period for investment is the primary determinant for 700MHz spectrum hotness. The Wireless Telephone and Broadband Carriers find this spectrum attractive since they are able to recover their investment in less than 12 months. This is awesome, just awesome. This is about four (4) quicker than current bandwidth i.e. 1.9 MHz and 2.4 GHz used for cellular and WIFI respectively. Why the payback period is less than the other frequencies is owing to the fact that the 700MHz propagation can go where no other frequency can go (beside TV). In addition, it is well known and accepted that the 700MHz has a presence in remote household (as channels 52-69) for many years, again, owing to its ability penetrating homes far and wide. Wow!, wherever there is a TV one will be able to access broadband Internet and we all know that TV penetration is high, much higher than Internet. This clearly indicate tremendous business opportunity for the players in this spectrum

Beside the technological financial payback (shown above) the FCC as stipulate that devices and applications operating in this spectrum would be ‘open access’ for a specific spectrum block, “Block C” which they dubbed as the public access spectrum. What is “open access”? This ability allows customers to buy devices they wish, load the software they want, and no restriction by vendors. This is huge for small and startup companies; finally, they will get a shot of competing against the stalwarts such as at&t, Verizon. The downside to the “open access” is the FCC caveat for block C. The FCC will re-auction “block C” without “open access” if their target of $4.6Billion is not attained. I hope that Google’s pledge of dropping $4.6 still stand even if the FCC implements not all the criteria they requested.
Well, we have to wait until January 24, 2008 when the FCC will begin the auctioning of the 700 MHz spectrum.

The 700MHz Frequencies – WiFi, WiMax, and Google


Is this the end of the wireless carriers’ dominance in the mobile market? Well, it sure is shaping up as they struggle to deliver products using WiFi and WiMax to their valued customers.
This is a challenge for them since WiFi has been around in the IP world for a number of years but is gaining momentum with the advent of Apple’s iPhone, the Blackberry Curve and Pearl, and other smart devices. The users of these handheld devices are demanding better, faster, current, and relevant web services such as meaningful content, VOIP, live TV. These demands are the challenges the wireless carriers are facing while the new services providers are au fait with these value added services and the technology. Apparently, they can make the transition into the wireless world by providing sleek, sexy handheld devices that are capable of access current content on the Internet, e.g. Apple with the iPhone.

I hope this is a logical segue to the current situation the top four wireless carriers in the US (AT&T, Verizon, Sprint, T-Mobile) who are experiencing reduction in their ARPU – Average Revenue per User (Subscriber). Is this due to WiFi, WiMax being utilized, and therefore cannibalizing pre-paid minutes? Is has been stated that some of these carriers are also suffering from churn since the introduction of the iPhone. If this is true then there should be a paradigm shift when the take-up of Google’s wireless phone operating system, the gobbling-up of small “new wave” mobile companies; e.g. Android, Zingku, the acquisition of a slice of the 700 MHz Spectrum, and the launch of the Google phone? These questions need an answer during the coming week.

Selecting a WiFi Phone

Selecting a WiFi Phone

We are currently in the processing of setting up our WiFi lab and to complete our configuration we need a physical WiFi phone and an IPA (IP Phone Adapter). Criteria established for comparison were:

The Cisco 7921 was selected as our benchmark product since we currently have the Cisco 7940
List price should be less than $250
IP Phone should be OPEN, i.e. not dependent on VoIP provider
Support 802.11 b/g/n
Support WEP encryption
Support standard VoIP WiFi SIP system

Below is our comparison table for selecting such a beast.

The iPhone Killer is not the BlackBerry 8820


The iPhone Killer is not the BlackBerry 8820


The announcement by RIM that the BlackBerry 8820 will support WiFi 802.11(a, b & g but not n) is great news for the mobile industry. I must say that Apple's iPhone has provided the caffeine in the mobile industry by increasing the adrenalin in its business customers who loves the iPhone but cannot part with their BB....I understand that they get the iPhone for their young ones and pretend to show them how to use it. A businessperson does have an undying love and loyalty to BlackBerry and finally they should have meaningful discussion about the 8820.

With RIM supporting seamless switching on its 8820 from WiFi to EDGE is a major boost to all those WiFi lovers...I am guilty of that love and right up there with T-Mobile and the VOIP guys. I understand that you can load up to 32G on the 8820 but there is only one slot…hmmm where can one find a 32G card? This is a positive step for RIM to develop a competing business product that 'mimics the iPhone...professionally.’

Well, Motorola, Nokia and my good friends at Sony Ericsson should be announcing a nifty product during 4Q.

This is just the beginning and we the users will gain as the market becomes a tad more competitive.

802.11n - Wireless LAN

802.11n - Wireless LAN

 Apple has adopted IEEE approved draft 2 of 802.11n and will be incorporating this technology in their Apple TV and certain Macs.

 Apple is not the first vendor out of the blocks with 802.11n but the beauty of this announcement is that at&t (according to cbsnews http://www.cbsnews.com/stories/2007/07/02/ap/hightech/main3008648.shtml) also announce free WiFi for some of their customers. This is a strong sign that the next generation of the iPhone will be 802.11n enabled and hopefully at&t and Apple will be in a position of implementing a basic roaming between their edge and 802.11 via the iPhone.  

 If not, I am betting on T-Mobile implementing this feature for their iPhone users once they commences deployment in Germany.
