Airspan Small Cells and Macrocells Portfolio, including 5G

Back in April, a presentation from Airspan showed that they have shipped nearly 500k small cells. Sprint has nearly 300k MagicBoxes while Jio has around 120k small cells.

As you can see above, Airspan has a range of outdoor small cells and as shown below, a wide range of indoor small cells.

Airspan recently announced that it has partnered with Rakuten, the newest MNO in Japan, to bring comprehensive 4G and 5G solutions to the world’s first fully virtualized cloud-native mobile network. The announcement said:

Airspan’s Air5G OpenRange28 mmWave platform in 28GHz will deliver ultra-high capacity to Rakuten Mobile with record time-to-market, enabling unprecedented monetization opportunities. Airspan’s open RAN platforms will provide Rakuten Mobile the flexibility to disrupt the economics of traditional network operators and lay the foundation for transformational 5G architectures. With over half a million systems deployed globally, Airspan brings its proven disruptive economics to the fully virtualized Rakuten Mobile network.

Airspan’s mmWave virtualized Air5G OpenRange28 platform utilizes Qualcomm’s FSM100xx 5G chipset and supports open RAN architectures, seamlessly connecting to Rakuten Mobile’s virtualized BBU to deliver the world’s most advanced open interface virtualized RAN solution.  The OpenRange28 mmWave platform supports multiple functional splits for the widest possible set of deployment options, ensuring Rakuten Mobile customers benefit from the highest level of efficiency and the best user experience in Japan.

Airspan's 5G products can be viewed here.

With so many innovators working with Rakuten, it would be interesting to see their 4G & 5G network rollout. Looking forward to some big announcements at MWC next year.

Tutorial: An Introduction to Macrocells & Small Cells

I have been meaning to create a video tutorial on Small Cells for a long time. The problem is that its not as easy as most people may think. To explain small cells concepts, its necessary to explain macrocell, C-RAN & DAS. This is what I have attempted to do in this presentation.

The slides are embedded below and can be downloaded from Slideshare. The video is embedded on slideshare presentation but if you prefer, the direct Youtube link is here.

Please note that this video is for guidance only. Many vendors & operators use their own definition which may not agree to mine. In the end, we are all correct 😉

'Inside-out' or 'Outside-in'

Going through my old presentations, I came across this prestigious lecture delivered by Dr. Tim Whitley of BT. The main argument of that lecture was, The future of mobile is fixed and the future of fixed is mobile. During the ending of the presentation there is a discussion on Outside-in v/s Inside-out. Lets look at those slides here:

The Future of Mobile is …Fixed from Zahid Ghadialy

Qualcomm is a big fan on Inside-out as can be seen here. Other small cell manufacturers support the inside-out approach too.

The question is, does inside-out approach matters any more. By next year many operators and devices will support VoWiFi in native client. Which means that even if your coverage is poor or non-existant inside, you will still receive voice calls and text messages. Data will continue over WiFi as normal.

An argument in favour of cellular is better/guaranteed QoS as in VoLTE and maybe new services can be available faster but private WiFi best (or no) effort is not bad generally.

What are your thoughts on this topic?

3GPP Definitions of Small Cells

While the Small Cell Forum defines the different types of Small cells clearly and these Small Cells can be said to contain the complete/partial functionality of the eNodeB, 3GPP definitions of Small Cells can be a bit fuzzy sometimes.

Generally, in the 3GPP documentation, there is a reference to Femtocells and Picocells. Femtocells are Small Cells that are defined as Closed Access (see my old post here) by 3GPP. The open access small cells are referred to as Picocells. Sometimes remote radio heads (RRH's) are also referred to as Small cells, open access type.

Relays, even though not referred to as Small Cells by 3GPP, is also referred to as Small Cells by some people.

'China Mobile' and 'Ericsson' deploy GSM Picocell/Metrocell in Nanning, the capital of China's Guangxi region

While the whole world has been focussing on HSPA+ and LTE small cells, a recent press release from Ericsson told us about GSM based 'City Site' deployed in Nanning. From the press release:

Currently, China’s urban construction is in full swing, and its mobile network coverage is rising. In the increasingly crowded urban environment, however, ensuring the quality of mobile-network coverage has become a problem.

In order to meet this challenge, Ericsson has launched the City Site integrated solution, and successfully applied it to China Mobile’s GSM network in Nanning, Guangxi. The City Site, which has been deployed with the standard RBS6601 base station, has an integrated Omni Antenna, which only covers a small area and is, therefore, easy to deploy. It could also be launched with just access to power and transmission cables.

According to the test of the live network, the City Site has effectively met the capacity and quality needs of network coverage, as well as ensuring excellent user experience.

Small Cells deployment report

Today, I went through the Informa's report on small cells. Some interesting points from the report as follows:

Microcells and picocells are already widely deployed in market but on a lower scale compared with femtocells. Metrocells are expected to enter the market during 2012 through operator trials or pilots and expand significantly during 2014 and 2015 primarily for 3G networks in developed markets and LTE in the US market.
