Today, HPE Aruba announced its Aruba Air Pass cloud service that allows for a hand-off between cellular and Wi-Fi networks. The service is enabled by Passpoint, which is a standard created by the Wi-Fi Alliance. The idea is that a mobile operator customer can go into a building with Wi-Fi coverage and, without having to "log on" to the Wi-Fi, the user's phone will automatically connect. Using Air Pass means that mobile operators won't need to build a cellular infrastructure in these buildings for customers to continue with their phone calls.
For mobile customers to see the benefit of seamless roaming from the Air Pass service, mobile operators will need to engage in a relationship with the property owners of the building. While this seems like a lot of work, connecting to Air Pass will be far easier than it would be for a property owner to install a cellular network inside the building. Examples of in-building cellular that can operate either on licensed, shared or unlicensed spectrum is a Distributed Antenna Systems (DAS) system or licensed small cells. Building owners or operators have to build new, in-building cellular if they want cellular coverage. Managed Service Providers, such as Federated Wireless, have begun selling a service to property owners where they will manage the cellular infrastructure for the owner.
Aruba has some competition for its service to allow Wi-Fi sharing to mobile operator customers. In February 2020, Cisco announced its Unified Domain Center as a means of sharing Wi-Fi coverage with mobile operators, as well, and claimed that it is at the proof of concept stage with operators. Also, Swedish software and services company, Aptilo, has created systems that allow SIM-based device users to roam onto Wi-Fi, as well. We applaud the efforts of Aruba, Cisco, Aptilo and many others who have built systems to allow device users to roam between cellular and Wi-Fi networks.
There has been a lot of excitement by mobile operators and cellular equipment suppliers about the 5G opportunity to expand to enterprises. In November 2019, for instance, Nokia discussed how enterprises are adopting its Private LTE systems to allow cellular coverage at customers such as utilities and shipping ports. We have been cautious on the idea that mobile operators will get lots of new revenue from providing cellular coverage to the enterprise; a year ago, we laid out our thoughts on the 5G Enterprise hype at the MWC19 show.
The implications of the emergence of services like Air Pass and the capabilities of Unified Domain Center is that Enterprise Wi-Fi coverage will be leveraged in the 5G era far more than all the hype about "5G" wiping out the need for Wi-Fi. However, we also feel that cellular systems will see growing popularity in certain enterprise verticals, as was evident at the MWC-Americas 2019 show.
Big themes at the show were WiFi-6, 6 GHz, and 802.11ah. We share some comments about the following organizations: WiFi Alliance, Commscope, Newracomm, Celeno, Cambium, Juniper Networks, On Semiconductor, Extreme Networks, Webb Search, Facebook, UK's Ofcom, Huawei, and 650 Group.
The WiFi Alliance and a handful of other speakers commented that WiFi-6 has lower latency than 5G, but the Alliance conceded that cellular had better mobility. We think the WiFi community is not doing enough to promote WiFi-6’s low latency capabilities
Commscope expects 6 GHz 802.11ax products to be shown at the CES show in January 2020 and that FEM and filters are not available today but will be by year-end or early 2020.
Newracomm is an 802.11ah (900 MHz WiFi) chip company that had won an award at the show. It claims to be an early leader in the market and based on comments made during presentations, we expect by 2H20, we will see systems and IoT services based on these types of chips.
Celeno, a stand-alone WiFi chip company, demonstrated radar on WiFi chip capability - the company won multiple award at the show. The company expects that a year from now, its Doppler on WiFi will emerge in products from SPs such as BT, Orange, and Comcast. The Doppler service only consumes about 3-5% of throughput capability when using Doppler and enables some very interesting capabilities such as fall detection, proximity detection, people counting and arm gestures.
ON Semiconductor's Quantenna group won an award at the show.
Cambium, in a presentation, explained that it is looking at an expansion to CBRS, 5G FWA backhaul, and 60 GHz.
Juniper Networks has been hiring in Europe as it expands its enterprise sales capabilities. It’s recently hired team made a positive impression on the audience. We tweeted about how great and fun the presentation by recent hire Jussi Nivikiemi’s presentation.
Extreme Networks presented its view that Artificial Intelligence won’t replace IT workers - it will just make them better.
A spectrum consultant - Webb Search - said that DFS is not working in the UK in 5 GHz and wastes a lot of bandwidth - most WiFi products don’t bother trying to operate one the spectrum covered by DFS. He advocated for using a database in the sky approach similar to what is being proposed for 6 GHz.
UK's Ofcom representative, Christina Data, explained that it is researching both 5 GHz and 6 GHz as a comprehensive solution. Ms. Data acknowledged that DFS may have some challenges and was diplomatic in response to questions about how 6 GHz will emerge.
Huawei advocated for an unpopular viewpoint (at a WiFi show) that 6 GHz device makers should register for IMT designation. In a panel that included German WiFi equipment vendor Lancom and Commscope, the other two vendors made counterpoints, including that this move to IMT will delay the rollout of 6 GHz by at least four years.
Facebook is advocating a non-AFC approach to low power 6 GHz in the US market. We have learned through multiple sources that it has recently a demonstrated a prototype of an AFC, however.
650 Group. The Chris DePuy presentation hit on three topics: unlicensed and shared spectrum impact on WiFi, WiFi and WiFi-6 shipments, and WiFi semiconductors.
