Broadband link

Not much today.. but here is a good link from a company thats into 802.16e. It's a white paper.

Rural Internet

Haven't been on here in a while. Just a have little to say today about connectivity

Within an Urban area, there are several technologies available today for providing Internet connectivity. This goes from Dial-up to ADSL and also hot-spots.

Once you get into the rural area, the limits are very obvious with mainly GPRS and EVDO for connectivity in a limited sense.

While there are many small solutions out there to provide wireless connectivity, it seem the best practical one to date is WiMAX (802.16D). This is the fixed version of WiMAX and would allow the level of bandwidth to sustain fairly good connections.

The issue with that is whether it will take off. The hype to get the mobile version of WIMAX (802.16e) will probably slow down the possible growth of 802.16d).

In summary, the main lacking for 802.16d is client support. Currently, you can get a 802.11 card for a few dollars. For 802.16d you need a big installation setup similar to a sattelite dish..

The other potential option would be to use 802.16d for getting into the community, then use 802.11 mesh technology to spread the signal around.

I think this whole topic is very important especially for developing countries. The US and Canada has this issue too so its very important.

re-inventing the living room

Interestingly, the rise of broadband to the home has change ways in which people can now entertain.

for example in the pass you buy a stereo to play music, dvd player or vcr for movies, console for games and no option to look at family pictures. Now with the Internet and personal computer, you can do all of the above in one place with very good quality.

The two competing options are the Xbox and the pc running windows or linux. For PC, microsoft has a media version to fit this purpose, see http://www.xpmce.com/ Linux has several such as freevo and MythTV.

The xbox has many options, like http://www.xboxmediaplayer.de/ and others. you would need to modify an existing xbox with large harddrive and boot rom etc. This can be found at various sites using google.

In respect to cost, $500US could get you a reasonable PC or modified xbox with 160GB hard drive, Tv-out card and remote control. top of the line will run from $1000 to $2000.00 but can be less if you get creative.

The interesting thing is there are numerous online sites that sell membership to get the latest movies and music. when I say latest, I mean before its selling on DVD etc.. most membership run for $50US for over two years at a time.

With this approach, you really do not need movie channels on the cable which means you pay off the above cost in a very short time if you are a movie lover. For music, all you need is a good set of speakers and you jamming. With many option of software, you could run a good party using this setup.

As I am in the process of setting this up, I would love to see if we could server the video over my home wireless network to a notebook or tablet PC. I tried to evaluate whats the best option and it seems the PC with either Linux or windows is best. The xbox would win if I was a gaming person but I am open to getting one for later use by the kids.

I will later show more interesting stuff with integration etc. Maybe add Voip into the mix with WLan phone etc..

Mobile Computing update

I ran into this link about mobile communication which I found to be rather interesting. I am very busy now, later I can give some more insights.

Voice Communication Gadgets

There are some interesting products on the market today. The one that catches my attention was this company www.vocera.com. They provide a communication system for enterprise like applications such as offices and hospital. It combines wireless, voip, voice recognition and text messaging.

It would be nice to transform this type of technology into more wide area usage such as with Cell phones etc.

The concept to investigate is how to make the person a part of the network, this meanings you can reach them by any available means at any time. This means some degree of translation from different medias.


This is a very good area to explore in light of broadband connectivity.

Time to rest

Well tonight is Shabbath. It reminds me that God cares about us by allocating a day of rest from the rigor of everyday toil and stress.

Its good to timeout and look at the picture every so often

Enjoy the rest.

More on Broadband

Looking at technologies today. WLAN provides the best bandwidth in respect to pricing. The main drawback is wide scale deployments of the magnitude seen with cell networks.

One interim solution is the use of Mesh networks, but this in my opinion seem to fit mostly campus type scenarios such as Universities and small cities.

With the coming of WIMAX, maybe the early stage would be an hybrid solution of using WiMAX as the backhaul and WLAn for client access. This will make sense since there is a large install base of WLAN client cards already in the market.

While its good to have options, it may not be easy to support dual or triple mode cards to get the best service where ever. Some service will need to stand out as the main connectivity option eventually

Maybe the next step is looking at practical applications of internet everywhere. I remember a few years ago, bluetooth was pushed as the way to connect everywhere, meaning you go to the gas station and to get gas but there would be connectivity to get directions and basic information using a wireless client.

What prevents this from taking off?

Broadband Wireless

Well, I am getting the hang of this thing now, so I can start to review some cool stuff.

There is a lot of interest in arrival of mobile WiMAX. Why is this? There are several options out there today. EVDO for CDMA, UMTS, HSPA and GPRS for GSM and the good old WLAN.

Two areas driving the need for WiMAX is Low-cost connectivity everywhere and rural broadband.

It therefore means to deliver WiMAX there will be cost pressure upfront for the service provider. Looking at the popular $20/month for dial-up and now $30/month for DSL.

A key element for WiMAX in the outset today is to deliver real Rural Broadband especially for developing countries. Instead of going through various technology stages, they can jump directly to real useful broadband service.

On the developed market side, the main driver I think will be full connectivity services, meaning you purchase a monthly package that includes, DSL, CellPhone and Wireless Broadband.

Now the other side that still out to jury is real applications. You are not going to walk around with a laptop just to prove you have Internet access. Tablets may even be too cumbersome but then PDAs maybe too small. What will make this fly in these markets. One option is Car PCs which have been around for awhile but not extremely popular. The main thing is the man to computer interface that will affect this whole thing.

Thats a good start, there is lots to discuss on this topic. More later

Wireless and Voip

My second blog using a different host.

I am very interested to investigate the trends with Wireless Technology, its mixture with VOIP and voice recognition.

Imagine the ability to be chatting on yahoo with someone driving in a car on their phone. The possibilities are great. You could also send an e-mail using voice only from a mobile phone.

The enablers I think will be mobile WiMAX and currently wifi for in building situations.
