I dumped adsl this week for the Vsat product from Sentech. WOW!!

The difference between this product and other "satellite" based connections is the up stream that goes directly from your dish to the sat, not via modem. Didn't think I'd live to see such speeds. Normal bussiness hours I manage to pull between 300kbs and 600kbs. On Wednesday (Pubic Holiday) I downloaded at more then 2000 kbs. That is broadband. Although much more expensive then adsl, I will never look back. A shame though that this kind of bandwith is not available from servers in South Africa (Telkom!!!!) The fastest local site that I could get was Mweb's tucows portal which yielded a noch over 1000 kbs at times.

The huge bandwith is quite usefull for foreign sites, but South African sites are not able to let you make use of this bandwith. An Interesting fact is that I am at least 6 hops (traceroute) from any South African server where adsl was only 3 hops away.

Their is the 600 ms delay for coms with the sat, which you do notice with normal browsing Having said that, pages load much quicker then I am used to, especially so for sites with high graphic content.

I was issued with 5 Ip's (one for the dish gateway) that leave me with 4 usable Ip's. Hosting seem to be quite fast as well, although I'm having some problems with in-address reverse lookups for the Ip's but it will be sorted out in the near future.

The service agreement guarentees 256k in although I'm getting much more. This will propably change in the near future with more subscriptions. The product is mainly marketed towards bussinesses which will probably leave plenty bandwith during night time (I hope)

To summarise, A GREAT connection. At a stage I was paying almost 8OOO for a 64kb diginet line . I'm currently paying R3500 for a line 512kb line that can not be stolen buy affirmative shoppers. You do the maths.
 
Hi Bacchus

Thanks for the info. I am certain many of our members were wondering about this service. It is great news that there is a trustworthy option available to users.

Do you use it for gaming? Ping times?

Regards,

Don't do much gaming but I will gladly help with a few pings. Just send me the Ip's and ports and I will get back to you.
 
Could you please trace the following benchmarks for me:

<b>york.boston.sierra.com</b> (USA-based Sierra server, US backbone)

<b>pitchfork.saix.net</b> Server on the SAIX backbone - down at the time of writing this

<b>clarity.jolt.co.uk</b> UK backbone

Tx very much.

Please note that I have other users on this line with bandwith in excess of 300 kbs while pinging. Might have an influence on what you see.

It's good to see that 256kbps is guaranteed!
I wouldn't get it because of the high pings, as I am a gamer.
Also, most ADSL users could buy many ADSL accounts for the same price.[;)]
 
Pings seem a bit high, but their is not that much to read in a ping! one ip packet traveling to another server may seem slow, but 100 packets send in succession will give you "ping" values less that 100ms. Remember that a ping is a round trip, but data is "streamed" from one server to another in various numbers of packets.

I'm not a techie but I know that a ping does not tell you much when sending or receiving large qty data.
 
Satellite is great for downloading and such but due to the nature of a the route satellite takes ie computer - beam up to satellite - beam down from satellite - server on the ground - target. It has a rather large lag making it all but useless for anything that requires realtime sending and recieving of information. IE gaming, large video confrencing and such things. Although it seems adsl is suffering major lag anyway. For gaming Diginet and isdn are proberly the way to go as sentech wireless service will go over satellite bandwidth as well. So you are looking at very similer lag on that as well.
 
The Vsat service is probably not ideal for gamers. Fantastic for my use with great bandwith, but the nicest part: No part of my signal goes through Telkom. (Sentech -&gt; Carier of cariers license)

The only shaky part of the deal with Sentech is that I'm dealing with yet another state owned Service Provider.[:(] Hope that they will take take notice of the dissapointing road that Telkom followed.

Anyway, although I'm not a ADSL user anymore, I still have a burning urge to actively take part in your cause. I read a white paper by some prof in the USA stating that South Africa is one of the coutries with the most potential to be a world leader in Internet technolgies and E-Commerce. This was based on technologies developed in South Africa (Read Web Security and Credit Card fraud control), the realitively low cost (in world standards) of operating a high tech company, the availability of tech skill and our time zone location. The obsticles pointed out was the availability of bandwith and the regolatory setup.

I hope that with enough voices and common sense from our government, that we will be able to stand up to all this potential.
 
My friends in USA and Korea uses ADSL to play online games.
ADSL must become ideal for gamers. [;)]

anyways thanks for the great news on Sentech's product.
 
Adsl should be perfect for gaming. Sadly telkom has made the bandwidth pool for adsl way to small so that during peak hours 7am-5pm ping times can go through the roof.
 
Just some interesting inside infor for you from Sentech....Sentech would be able to deliver their product at much the same price,or competitively close to Telkom's ADSL costs, BUT Sentech are reliant to a degree on some fibre optic infrastructure that they have to rent from.....you guessed it, Telkom. And, Telkom have to refused to negotiate their price for this fibreoptic infrastructure preferring to charge Sentech retail pricing instead of negotiating a lease agreement or supplying it at wholesale costs. The price differential between ADSL and VSAT is this extra cost.
Kid you not - go have a look at Financial Mail back issues - there was a whole article on this about 6 months ago.
Nice one huh? Competition in SA going to make a difference? I don't think so, not until Telkom are brought to book.
 
Peapod is right - we need more raw infrastructure providers (i.e. in the ground copper and fibre owners). Competition in the layers above the raw transport medium, although required, will not make a difference alone. We need companies that can compete head to head with Telkom in the provision of carrying electronic signals from A to B.
 
i heard it's risky for telco investors to install new cables under ground.
cuz' cable thieves waiting for it. [V]
 
Definetely the case for copper, but then again, why would any telko install new copper cables with less bandwith capability. The ideal is to install a fixed wireless infrastructure (3rd generation something like the 1XEV-DO standard which have been deployed with great success in the world). This type of infrastructure is cheaper to roll out nation wide, easier to maintain (read theft) and will be able to provide huge bandwith (at least locally with peering with Jinx and Cinx). The only bottleneck will be International bandwith.

This is the route the SNo should take. To establish a cable based network like Telkom's will prove to be a very expensive unproductive excercise. Telkom tells us that the most lucritive bussiness sector is data lines (possibly because they are bound by their license agreement to install telephone lines in low income communities). If I had the oppertunity to run the SNO, then this will be the market on which i will focus. South Africans are hungry for bandwith, and if the service are up to speed, many wouldn't mind paying a couple rand extra for the service. The SNo will also be forced to do some chartiy, like Telkom, but with the maturing broadband wireless technology around, I would definitely focus on the broadband sector including evry person on this forum.

While going through postings on this site, I came to the conclusion that many users here miss an important point. A few facts to try and explain what I'm trying to say.
1. The government is the biggest shareholder in Telkom
2. Telkom generates huge profits, which come in handy when you
are trying to win a few votes by building houses etc.
3. Telkom's supposed opposition ( SNO, Sentech) also have the
Government as Major shareholders.
- The SNO through the 30% shares of Esitel (Eskom) and
Transtel (Transnet). Both have the Government as major
share holders.
- Prior to 1996 Sentech was a division of the SABC. In 1996 the
shares was transfered to the Public company
(Sentech as we know it today) with the Government as the sole
shareholder
4. ICASA (Independant Communications Authoroty of SA) is fully
subsidised by the government (via the Communications departmend
of Ivy) and all revenue is directed to the Department.
5. Telkom was a monopoly by law. The telecoms act forbid any
party (apart from telkom) to do any kind of telecoms. (Government
protecting its assets)

So yes Telkom give us ****ty service and products, but i see them merely as puppets of a government that havent come to grips of the IT potential that this country offers.

I think I read an article that Eskom is currently testing power line based internet access or something.
which you can gain internet access from the power socket on the wall!
dunno how fast and reliable will that be.. but curious stuff.
 
I read something similar being tested in the UK recently.
Telkom will get a "shock" if this gets off the ground. I bet there are more houses that have electricity than phone-lines.
This will be an interresting topic to keep in mind. Hope fully it has some real kick behind it. [:p]
 
Interesting article about internet access through power lines:
http://dsonline.computer.org/0307/f/news.htm

Looks like this technology will be available in the US soon.
 
Last i heard sentech wireless was sheduled for somewhere in 2005/2007 Dont get your hopes up :P

What exactly is the instalation costs and equipment costs for the up/down converter, and sattelite modem?
