I have some questions regarding 3Mbps.. (for the future)

Is it possible for you to remove the 512Kbps "cap" -even temporarily-to test whether this has any effect on ping times.

Do you think Sentech will introduce more packages ie. 1024Kbps or rather 128/256/512/ uncapped(3Mbps)

Assuming you can test 3Mbps, how well does the modem work at that speed? I mean, does it get anywhere near the full 3Mbps and does this depend on signal strength?

Stupid question here, will the current modems be able to be upgraded at low cost to something like 5Mbps within the same technology (what are the fundamental limits of the current technology used.. 3Mbps or more?)

Thanks for any replies..would be interesting to know this stuff for the future and maybe to settle the annoying ping issue. Those 5% of all people (gamers) sure make a lot of noise [:p]
 
If you want better pings on a wireless system, W-CDMA is definitely not the way go to. Not even CDMA EV-DO is the way to go. Look into flash OFDM.

Nextel is deploying it in South Carolina right now: http://www.corante.com/bwia/archives/002412.html

Latency is under 20ms to the first hop compared to almost 40 to 50ms on my cellphone at 600 Kbps.
 
The higher the speed, the harder it is for Sentech to gurantee it, especialy for people with low signal.

Hmmmm ... Your questions are a little more complicated than may seem at first glance. I’m going to take the easy way out and just give you the simple answers :) It is technically possible to remove the 512k throttle. However there are many many more implications in that idea which affect everything from backhaul to the supply of both RF and IP capacity. So even though it’s technically possible it’s very unlikely to happen.

More packages may be introduced at a later stage but the capacity you are mentioning is way beyond the target market for MyWireless. Fixed wireless products are in development (similar technology, just not portable) and these will later cater for higher bandwidth requirements for business.

The throughput will depend on many factors including distance from the high site and signal strength. At 3Mb the coverage area of a single high-site will shrink considerably.

If you purchase 5Mb of Internet capacity I’ll give you a modem for free so you won’t need to upgrade :) As with most technology I’m sure improvements will come at a rapid rate and someone who buys a modem tomorrow may have a higher theoretical speed limit than the modem you bought yesterday. But how many consumers do you know that can purchase that kind of capacity?
 
The question of 3Mb Bandwitdh. Accroding to the specification yes it can be done, however, lets say the node(b) can take a 30mb throughput with a Microwave link to Sentech of 30mb you would then be using a considerable amount of infrastructure for this, and as you can imagine the cost of the Node(b) radio and the MicroWave links, I think that the price would be much higher and more comparable with diginet. Also, the sharing solution or contention ratio would have to be setup up specificaly for that package, so yest it can be done, the price I am not sure. DW would be the best person to ask about this.

greedyflyza, in reply to your one question:

Currently the 128k, 256k and 512k restriction "cap" is only at the so called final outlet.
In other words as things stand atm, from your modem to the server and back, the data flows at maximum speed, depending on what bandwidth is available.
Although the NodeB's have the facility to do the "capping" at that point, this is not the case atm, so maybe if it was, there might be a ping improvement, which is the opposite to what you are thinking [:)]

You are missing his point, he wants to test this re: possible lower ping times.

dw, I know of someone who wants to buy 5mbps...

guess who [8D]

Why do you have to "put your two cents in"... but it's only a "penny for your thoughts"? Where's that extra penny going to?
 
Will ppl give up on ping times already?
Rodent has clearly and very adroitly indicated (http://www.myadsl.co.za/forum/topic.asp?TOPIC_ID=2452) that the poor ping times on the IPWireless system are inherent to the system architecture, equipment and signals, and are not affected by bandwidth. So whether you have 128K or 5MB in the same location, your pings will probably not change.

....yea, and telkom is providing the best service ever....


I've learnt not to accept what I read or get told (as opinions) from other people.

Never give up, never surrender (unless she's a hot chick with big titties!)

Look.. I'm not a gamer so I dont care about ping times. I'm just interested to know what happens when the modem works unrestricted and what the effects of that would be. I'm very happy with my pings and my connection as a whole - I just want to learn more about it and the future it holds (24 month contract..)

Perhaps you dont understand. Do you think that I think 3Mbps means more speed and better pings? Please.. try to understand why I was asking what I did instead of just shooting it down as a ping question.

Back to the topic..
So then what happens to the "left overs" when only the 128k out of the maximum speed of 3Mbps passes through? Is it dropped/buffered etc and thus, doesnt this introduce large overheads (please excuse me here..ping question) thus increasing RTT.

Uhm .... Ok ... ppl correct me here then ;-) If I was to talk to another modem on my local tower would I still be routing via the external server ? If not will I not be running at a far better speed modem to modem... ? OR does all traffic HAVE to route via main server ? If so then it would certainly be ideal if every major center had it's own server... maybe even eventually every tower ? This may reduce overall network latency.

I know this is related to another forum re: direct connect -- but I'm just trying to get my head around what ProASM is saying.

Does any of my rambling make sense ? hehehe

Yes currently everything is routed through the main server.
