Heterogeneous Networks – How complex can they get?

It’s no secret that mobile networks are under tremendous stress, and data capacity is at an all-time high. Consumers want and require constant connectivity and the standards have become very high, making operators play catch-up with the higher set of expectations from customers.

Take airport Wi-Fi as an example…just a few years ago it did not even exist, and today, customers are outraged when it is not available or it is of poor quality. The feeling has become that Wi-Fi, cellular connectivity and the ability to connect is no longer a service, but a common human right.

Are you ready for the switch to 4G LTE?

This post is by Eyal Amit, Product Marketing Manager, Amdocs

Plenty of service providers (and their end-customers) have jumped on the 4G LTE bandwagon. As a result, two of the most immediate and noticeable changes we are seeing are the speed at which data services are running and high-definition voice quality.

And that’s great…assuming that everything works as it should, and customers receive the quality of experience they were promised. But sadly, many 4G LTE implementations do not live up to expectations due to the challenges that lie within the core elements of these networks.

At the heart of SpiderCloud’s scalable 3G/4G small cell system is the Services Node (SCSN), a “local” control point for the small cell network deployed inside the enterprise over existing Ethernet. It’s also where the enterprise edge meets the mobile operators edge network. The small-cell system can provide cellular capacity and coverage to over 1.5 million sq.ft. of space and support for 10,000 voice and data subscribers.

Beyond coverage and capacity, after credibility has been established with the IT department, the Services Node is a strategic point of entry into the enterprise IT environment for mobile operators and business partners to service IT, and a potential great revenue opportunity.

Hadi Hariyanto, senior researcher for Telkom, Indonesia is taking part in a panel discussion on integrating carrier Wi-Fi into telco networks on Day Two of the LTE Asia conference, taking place on the 18th-19th September 2013 at the Suntec, Singapore. Ahead of the show we find out more about the complex spectrum issues that are holding back the deployment of LTE in Indonesia.

A year ago you had completed LTE trials in Indonesia. How has your LTE network progressed since then?

We are monitoring the progress of the LTE ecosystem including device maturity, VoLTE, and new business opportunities. Since it is most likely that we will be using re-farmed spectrum, we have conducted an intensive study of heterogeneous networks. This technology will enable us to anticipate the possible challenges and opportunities of delivering seamless mobility between 3G, LTE and Wi-Fi networks.  We also actively contribute to a European ICT Project, related to LTE small cells and mobile cloud computing, which is called Tropic.  We believe mobile cloud computing will be a great source of new revenues on top of the LTE network.

Fumio Watanabe, executive adviser, KDDI & corporate officer CTO, UQ Communications, Japan is delivering the opening keynote on Day One of the LTE Asia conference, taking place on the 18th-19th September 2013 at the Suntec, Singapore. Ahead of the show we get an insight into what makes KDDI special compared to its rivals.

How has your LTE network developed over the past year?

Unlike the usual approach of launching services with limited coverage, KDDI adopted a far more aggressive strategy when it launched LTE services in September 2012. KDDI aimed to solicit the advantages of LTE by starting with a wide nationwide coverage on Day One and by rolling out the network at a faster pace than had ever been achieved elsewhere. Eight months after the service launched, the population coverage using the 800MHz band reached 97 per cent as of May 2013 and will be further expanded to 99 per cent by the end of FY2013 (Total 3G/LTE subscriptions: 38.6 million as of July 2013 ).

KDDI’s approach to deploying LTE is not a mere implementation of LTE, but is truly unique and ambitious. By introducing LTE in multiple bands (800MHz, 1.5GHz and 2.1GHz) at the initial launch, we have secured the capacity and coverage as well as compatibility with global handsets, while saving the cost associated with network deployment.

Managing the interaction between 2G, 3G and LTE within Heterogeneous Networks

This post is by Neil Coleman, director global marketing, Actix.

As networks become increasingly complex and demands from subscribers soar, mobile operators face common issues when they lack a reliable, consistent and accurate view of the network. 

Mobile data services are undergoing tremendous growth. As a result operators are busily knitting together a Heterogeneous Network (HetNet) of access technologies from cellular towers, rooftop antennas, metrocells, femtocells, and Wi-Fi to Distributed Antenna Systems. This development is being driven by subscriber demand for consistent wireless broadband coverage and capacity, with the result that the mobile network is moving increasingly ‘closer’ to the consumer.

LTE offers a step change in mobile data performance, setting new expectations for customer experience. LTE will increase interaction with the network, increasing the demand for mobile multimedia services – online television, video streaming, social networking, and interactive gaming.

Considering the huge variations in performance, range and capacity between different access technologies and spectrum bands, operators will need to carefully control the interactions to provide a consistent subscriber experience. Simply put: customer experience in HetNets will be defined by the poorest network performance the subscriber typically receives during normal day to day usage.

If operators get this wrong, subscribers could experience catastrophic drop-offs when handed over from relatively under-utilised LTE networks to congested 3G/2G networks.  Similarly as subscribers leave Wi-Fi or small cell hotspots and re-join macro networks speed bumps will impact the always connected data experience new services rely on.

All of this requires operators to get the initial coverage mix right and ensure handovers and interactions occur at the right places at the right time. Critical to this is an understanding of how subscribers and data traffic flow across the network and the geography. This type of information can be obtained from systems that deliver increased network and subscriber intelligence. Software platforms such as ActixOne are designed to deliver real-time geo-located subscriber insights to drive everything from long term planning through to optimisation and SON.

This intelligence then enables the operator to shape and manage bandwidth to deliver the required quality of service, improving and optimising network efficiency so that the transition across the HetNet is a smooth, invisible and painless experience for the subscriber.

Network CTO, Monaco & Islands Cable & Wireless: “Markets such as the USA are driving HetNets and consequently we keep a close eye at that momentum.”

joffreCyrille Joffre, Network CTO, Monaco & Islands Cable & Wireless,  is taking part in a panel discussion in the Backhaul Summit track on Day Two of the LTE World Summit, taking place on the 24th-26th June 2013, at the Amsterdam RAI, Netherlands. Ahead of the show we quiz him on his views on the challenges that are thrown up by HetNet deployments.  

What’s your vision of a Hetnet enabled future network and how soon will it become a reality?

Hetnets are seen as a key parameter in the high data usage areas and a crucial part of the in-building coverage equation, and promise to alleviate data traffic stress at the macro level. More importantly, the tech will enable better business cases by leveraging specific heterogeneous deployments such as “Licensed Femto”, “Bring Your Own Wi-Fi”, and “SP Carrier Wi-Fi” in different scenarios (both offload and onload) for residential, SMB/SME, metro and hotspot.

Spectrum and mobility are two fundamental characteristics of wireless networks, best defined respectively by ‘scarcity’ and ‘unpredictability’. I therefore envision that HetNets (i.e. a multi-layer, multi-mode, multi-band network architecture by common definition) help bridge these some gaps. As for Wi-Fi, unlicensed radio resources could be blurred with licensed cellular resources at user data session level (already demonstrated in labs). That would prove to be spectrally efficient and also to remove complexity for devices in connecting the network, as well as in QoS management, and as a result delivering a better user experience. Markets such as the USA are driving HetNets and consequently we keep a close eye at that momentum.

I’ve heard the opinion that the dedicated backhaul required for every small cell installed will destroy the economic benefits that they bring in terms of offload. What’s your view?

The answer to that question depends is very much driven by local market considerations. There are multiple backhaul technology options available at different cost per gigabyte and with different operational issues. The fact that small cells may not require a ‘five nine’ carrier grade mark may also relax some pressure on the business case. Finally, operator capability to monetise some of the business cases listed above will play a role.

Practical difficulties in obtaining planning rights will severely limit the practical use of small in the real world? To what extent do you fear this will be true?

The reality is that small cells only improve mobile experience if you place them in close proximity to subscribers trying to access the network. Whether operators have experience with street-level site acquisition and/or aesthetics is a question. Negotiation, approvals, and fees vary between councils and regions but we have seen some local councils making deals with operators for street furniture. Other interesting street-level issues also emerge such as that power to street lamps is shut off at seven AM in most cities, and no operator would enjoy a small cell blackout every morning. And once the small cell is fixed onto a lamp post, climbing that lamp post every time a fault occurs becomes cumbersome for a technician. Site planning will be key.

Why is the LTE World Summit such an important show for you to attend?

As fixed and mobile service providers for both residential and business segments, LTE plays a key role for our businesses, and not only mobile. This summit is also the place to get a flavour of what your peers are doing, the good and the not so good. Finally, you will probably be exposed to the latest 5G labs testing happening worldwide!
