A lot of telco just waste so much money in their internal dept with so called development or research which after so many years bring no good result or wrongly plan in investment.  End up the extra cost need to pass out to consumer. Just my 2 cent.

Your view where if it doesn't directly affect the end user, it does not mean it's a waste of money. The market will dictate at what price the Operator can sell your the service. If one Operator has a high cost base, it only means that the margins will be lower compared to it's competitor.

For vendor, yes R&D is very important. But for telco vostro78 is right. It is not very important, but still have the importance.. for example researching and testing new technologies (e.g. LTE/LTE-Advanced), market trend, devices/usage trend, spectrum trend, etc... developing and applying them to the network where/when applicable, to enhance user experience & reduce Capex/Opex. For example, it didn't take days or weeks to deploy 4G/LTE, it tooks months/years before the telcos feel comfortable to launch it as commercial service to paying-customers

Generally there are a few different technical teams in Operator:

R&D
Not all Operator has this team; Operator that have R&D team would be major players (NTTDocomo, Vodafone, China Mobile, etc).

This team will heavily participate in standardization (3GPP, NGNM, FTTH Forum, IEEE, etc) to ensure that the ecosystem is growing according to the needs of the Operator and it's end user.

Examples:
SON (Self Organizing Networks) where it helps in deployment and optimization of the network.
LTE Carrier Aggregation pairings

Strategy
This team decides the 5-10 year strategy of the company; which includes spectrum strategy, network architecture, product offering, etc.

Proof-of-Concept or Trial will be generally done by this team.

Engineering
This team designs the actual deployment; how many sites, where are they, etc etc.

Operations
Manages the network; including bug fix, outages and etc



My view is R&D team is important to drive the whole ecosystem but it's not crucial in every operator.

You mentioned that mobile operator is never serious in offering fixed broadband. It's kind of an oxymoron isn't it? Mobile to provide Fixed.

One of the most expensive and finite resource that a wireless operator have is spectrum. To provide the experience that of fixed broadband thru wireless will require multiple fold increase of CAPEX (more spectrum and sites) to achieve which will then break the business model (ie. you would have to sell the service at a higher price than the fixed counterpart).

I can safely say that most operator understand what you are saying and this idea will be killed even during conceptual phase based on what I've mentioned above.


An analogy that I can provide is like saying why can't we have all taxis to be supercars so that we can provide similar speed to an airplane.

It is not entirely true to say fixed broadband should not be associated with wireless models.

4-5years back both Time Broadband and Jaring had reached a certain level of success by offering the Webbit and SOMA Networks CDMA solutions that offered UNLIMITED fixed wireless broadband packages to users in cities upto 2mbps. It was until faster TM Streamyx and UniFi packages were introduced which caused their decline of use in urban areas.

This also further strengthen the case where it's futile to use mobile to compete in the segment that fixed is dominating.

I'll share some important information to you about wireless resources base on rigorous studies made recently by telco vendor labs(vendor name witheld). Those who eager to know why Digi's 3G network and the other mobile telcos seem to have very frequent drop calls here's the answer:

It was discovered that data utilization which shared the same resources as fixed networks were not the cause of congestion in mobile telco networks but it was the high consumption of consistent L3 signalling(RRC signalling) that bogged their networks down

But rest assured the LTE specs beyond Rel. 8 has already made great improvements to improvise on this since it'll be optimized to handle pure data-play services including IP based VoLTE.

UMTS 3G networks used to have 5 RRC signalling states but with LTE onwards now they've simplified it to ONLY 2 for much greater efficiency - RRC_idle and RRC_Connected.
You've mixed air interface resources with baseband capabilities. Signaling only takes up relatively small portion of air interface. What the report is trying to point out is that the CNBAP capability of the Node B can't cope with the increase of signaling due to smartphone.

Remember, the limited resource is the air interface. Solving the signaling problem won't give you much help in terms of giving more throughput.

QUOTE
But this is no excuse for pure data WiMAX networks that was actually meant to provide fixed broadband services from the very start. Why did they end up getting confused and mixed up with package plans similar to UMTS/HSPA+ players?

Because they (WiMAX) are competing with other mobile broadband products, not fixed broadband.


One more point that I would like to point out is that mobile networks will always have longer latency compared to fixed. This will always be another limiting factor for mobile networks.
