Dense Network Architecture – Why is it Important Now and Why Should You Care?

Dense Network Architecture – Why is it Important Now and Why Should You Care? 

For the last 15 years iBwave has supported the majority of the carriers in the world through millions of in-building network deployments as they focused on a smooth and secure transition to the next generation of technology e.g. 3G to 4G. For the next 15 years we plan to accompany our carrier and enterprise customers on the same successful path where DNA (Dense Network Architecture) will play a central role.

DNA is the Path to 5G

With the completion of the first 5G new radio 3GPP standard, the wireless industry is in the final dash towards commercialization of 5G technology potentially by 2019. Major wireless carriers are actively conducting trials to prepare for the fast approaching commercialization phase of 5G. As an integral part of the wireless eco-system, iBwave is working closely with its partners to ensure that they are well-prepared for this final step. We have a clear vision today that networks are becoming denser, this is true from a couple of different perspectives. First, we see the fixed architecture is evolving towards richer fiber-based networks for both backhaul and fronthaul. Second, we see that there is a densification of Radio APS from 3G to 4G and also in Wi-Fi with the number of global Wi-Fi hotspots growing exponentially, and forecasted to grow by 454 million by 2020 (Statista). Also, a total of 2.3 million Small Cells were being shipped last year (Source: RCR).

Don’t Forget the 3 80s

Industry trends and numbers shows that data traffic is increasing at a rate of 80% per year, we also know that 80% data traffic originates in-building and that 80% enterprises are ready to switch providers if they get better indoor coverage in an effort to improve customer experience. We can call this the 3-80’s rule and if you look at it you should start thinking of your Dense Network Architecture (DNA), from an in-building standpoint. It is important to take this approach because this is where most of your traffic is happening and this is where most of the enterprises will focus their energies to improve quality of customer experience. Today however we are not seeing this mindset as a majority of the early 5G trials are happening outdoors.

Ensure Your In-Building Networks Are 5G Ready

To address the above, at iBwave we think that 5G trials need to be conducted indoors alongside the existing outdoor trials, to highlight potential deployment issues for your Dense Network Architecture (DNA). Potential issues such as the current structured cabling and whether it supports DNA, or not? We have to move into a fiber-rich architecture inside the building, we need to figure out whether passive optical LAN is going to replace the typical CAT 5 or CAT 6 structure cabling? The 3 80’s rule should make us focus much more on in-building because that’s where the traffic is. This will help us pin point potential issues which might be very critical, for example whether the current cabling CAT 5 and CAT 6 is able to handle 5G or whether this next gen technology requires fiber rich networks inside the building.

Ask the Insiders

iBwave is happy to help our Carrier and Enterprises customers navigate the world of DNA and 5G networks by helping them prepare in advance and choose the best options. If you are an enterprise and you are curious about hearing what DNA and 5G will mean for you then come talk to us.

A New Release of iBwave Design is Here

What’s iBwave Release 10 About?

The newest release of iBwave Design 10 provides teams with everything they need in a software to design for new and emerging wireless technologies and tackle the challenge of designing for dense environments. 

Teams can now use iBwave Design to really leverage new technologies like LTE-Advanced, LAA, and CBRS to optimize the data throughput rates of the network and provide network subscribers with the seamless mobile experience they expect from carriers. 

What are the new features?

The key new features for iBwave Design Release 10 are:

  • Body Loss Modeling
  • LTE LAA with Carrier Aggregation
  • LTE Best Server Map RSRP, RSRQHandOff Matrix
  • Hand Off Matrix
  • Frequency Reuse Architecture

Body Loss Modeling:

This feature allows you to consider the impact of body loss on prediction for high-density venues such as stadiums, convention centers, shopping malls, etc. Especially useful in stadium designs where it is crucial to consider body loss to get prediction accuracy. 

Body loss modeling enables a higher degree of design accuracy in terms of SNIR calculation and also helps you and your team generate an optimal bill of materials for new DAS antennas to support increased data throughput.

LTE LAA with Carrier Aggregation

Leverage the unlicensed 5GHz spectrum as a secondary carrier to boost the speed of your LTE in-building network and achieve true LTE Advanced with downlink speed up to 1 Gbps. 

This also enables you to leverage LAA to improve network capacity by off-loading cellular data traffic on unlicensed spectrum while saving on licensed spectrum cost. 

A design combining LAA with carrier aggregation allows carriers to off-load part of their data traffic on this unlicensed spectrum to offer a better data connection while saving on spectrum cost.

LTE Best Server RSRP, RSRQ

With this new feature you can quickly troubleshoot interfering sectors and easily optimize for higher data throughput rates by probing with the 1st, 2nd, 3rd or 4th best server. 

Network densification often implies an increase in the number of sectors to provide higher capacity in different zones. However, by doing so, it could generate new unwanted interferences between sectors, in turn negatively impacting the overall quality of data connectivity. LTE Nth Best Server RSRP, RSRQ allows to quickly pinpoint interfering sectors so that the design can be easily optimized for higher throughput.

Hand Off Matrix

The hand off matrix is a new output map to quickly spot handoff overlap between sectors. With this new feature, you can now further optimize sector configuration with correct handoffs while saving cost on equipment deployments.

I really like the updated that have been made regarding LTE-LAA and Best Server/Handoff Matrix. This will allow troubleshooting a design to become faster.

Frequency Re-Use Architecture

This new feature allows you to re-use multiple channels with LTE bands to fully leverage all the available LTE licensed spectrums while reducing interference between adjacent sectors to increase overall user data throughout.
