I tend to agree! The Cell Networks are eating up all the spectrum leaving no spectrum for smaller players to use.

I think any company should have a limit to how much spectrum they are allowed to hold at any given time......

Methinks she requires educating regarding what certain frequencies can/cannot be used for...

But they serve millions of people with that spectrum, where a smaller player may just connect a handful of corporate clients with their spectrum. Surely the people who make the most of their spectrum would be the ones to get more?

Really?? Maybe substantiate your statement with some data:

What spectrum allocations do the various cell networks have? What are they doing with it and how many customers are they serving with it?

Then; how much spectrum is left for the 'smaller players'?

RPM that info used is not great,but probably good to get the point across along with the coverage maps. There are many other ways to improve coverage and capacity, many clever ways. This is perhaps what ICASA is getting at.

But look at it this way, MTN and VC refarmed spectrum with almost no loss in quality and capacity on GSM 1800, Cell c is using one of its WCDMA 2100 channels to push LTE, also without a loss of quality or capacity. This very easily illustrates ICASA's point, operators need to wake up and really start looking into better ways of maintaining quality. Yes there is a limit at which capacity will need to come from new sites and more spectrum,but the introduction of LTE by the big 3 in SA clearly shows where these operators are trying to take the easy way out. In my opinion this is what ICASA is trying to get across.

That said ICASA is also at fault, 800 Mhz spectrum needs to be released and some sort of multi-operator network needs to be put in place in order to provide rural broadband services. Analogue TV also needs to be turned off, there is a lot that is happening in the sub 900Mhz area and having the analogue TV switch off delayed is further stopping development in SA

The different blocks show the coverage for a singe tower at different frequencies. Basically showing that, the lower the frequency, the better the coverage. That's why freeing up 800MHz is so critical.

Jannie this is limited for capacity, 800 is not going to help us in urban areas where capacity is key.

after the interview, marcia socikwa went to wikipedia to find out what "spectrum" is.

I'd love to hear about them. What are they?

I know quite a few people who would disagree with you over on the Cell C forum in particular, but also some VC and MTN subscribers who say they've noticed a steady degradation in network quality.

There is (almost) always a trade-off to be made when optimising. You just try to make the negative impact as minimal as possible.

The problem here is the same one I sit with every day: People placed in positions of power that knows sweet blue f-all of the business/technology and then making decisions based on their own guesswork rather than trusting the facts/data/opinions given by engineers/specialists. When you don't play along (and burry your head in the sand) you are branded as negative and obstructive ... a relic from the past. But when the consequences come knocking ... guess who gets to explain to auditors what happened ... and who's head is on the block.

This is all so familiar.

there is actually sufficient spectrum for both incumbents and new entrants - probably around 1 000MHz which could be licensed now...this will not always however be optimal for its intended use but it is also probably fair to say that SA does not need another mobile network, it needs more competition in the provision of mobile services

but you get the feeling that spectrum is now in the hands of politicians, not engineers, and we are all suffering as a result


...and remember folks that a closed mouth gathers no feet

Yeah, the principal of 'use it or lose it' should also apply to gov depts. Let DTI take a crack at it ... heck I think even Marthinus would have done more with it by now.

There are a few, mostly involving clever tricks in terms of looking at traffic peaks and dips and user behaviour. Then each vendor will have capacity enhancements which can be called upon instead of adding in sites or "antennas", these can be software and/or hardware. Optimisation is a bit of an art in this regard, every cluster will have a different combination and this is what needs to be found in order to achieve results.

Yeah I agree there are some cases where its very bad, but to say its due to the refarm is probably a shot in the dark, perhaps a few cases are caused by the refarm but I would expect that VC and MTN did a good job in the refarm regions. Cell C is a special case, go back 2 years when everyone was loving the 5mbps+ speeds, I said it wouldnt last. After that taste of course their subscribers are going to complain now that they are stuck on <1mbps. User experience and expectation is very different from poor network performance.

No amount of clever tricks or re-farming will be sufficient to cater for the explosion in mobile data. Within the very foreseeable future the volume of mobile data will outstrip fixed line data.

DoC/ICASA needs get their asses in gear regarding the sub-2600MHz spectrum, and especially the 800-900MHz range, or else we will be left behind (still!).

They cannot allocate it at the last minute as network operators need time to plan and source funding as, believe it or not, they do have medium/long term network roll out plans! New sites are not rolled out overnight...
