Netgear Expands Orbi Wi-Fi System Family with AC2200 Kits

Netgear introduced their first product in the Wi-Fi system / mesh category, the Orbi, in August 2016. Its dedicated wireless backhaul (4×4 802.11ac / 1733 Mbps) and 2×2 radios with MU-MIMO support for the clients (on both the router and the satellite) made it one of the best performing Wi-Fi system kits in the market. Since the introduction of the Orbi RBK50 (AC3000), various vendors in the Wi-Fi market have come with their own variants. The increasing competition has turned out to be good for consumers, resulting in kits getting introduced at very competitive price points.

Many mesh systems come in packs of three, but, Orbi stood out with its claim of being able to blanket a 4000 sq. ft house with just a router and a satellite. Despite the high price (mainly due to additional hardware, compared to a regular router), mesh / Wi-Fi systems have been enjoying very good market reception. In order to tackle the increased competition (often coming in at a lower price point compared to the Netgear Orbi RBK50 kit), Netgear is introducing two additional members in the Orbi family – the RBK30 and RBK40. Like the RBK50, the main unit and the satellite in the RBK40 are similar in appearance and available interfaces. However, the physical dimensions of the RBK40’s components are smaller than that of the RBK50. The RBK40 and the RBK30 share the same router, but, the satellite in the latter is of the wall-plug variety and has no wired ports. The other differences between the three are summarized in the table below.

Netgear is able to reach these lower price points due to the following changes compared to the RBK50:

• Replacement of the 4×4 backhaul radio with a 2×2 one (AC3000-class to AC2200-class) in both the RBK30 and RBK40
• Updates to the power amplifiers to meet the lowered range requirements in the RBK30 and RBK40
• Removal of the 4-port wired switch in the RBK30’s satellite

During the press briefing, Netgear emphasized that they support both PC-based and mobile app-based setup for the Orbi. Particular stress was also made on the ability of the Orbi kits to operate effectively without any reliance on the cloud (unlike products such as the Google OnHub that have encountered various issues due to over-reliance on the cloud for day-to-day operation).

Netgear is also making the satellites available for purchase separately. The price points for these extenders range from $150 for the wall-plug variety to $250 for the one with the 4×4 backhaul link.

The new Orbi products also use the same Qualcomm Atheros IPQ4019 network processor SoC, along with the Wi-Fi SON features. While retaining the same feature set, the RBK30 and RBK40 expand the target market for Wi-Fi systems. The lower price points will also help Netgear in tackling the increasing competition.

Qualcomm Announces 802.11ax Access Point and Client Solutions

Wi-Fi platforms have traditionally focused on peak speeds. However, evolving usage scenarios (such as stadium and campus environments and even households with multiple Wi-Fi devices) have led to the appearance of standards aimed at solving the ‘capacity’ problem. We saw 802.11ac Wave 2 devices come to the market over the last couple of years. MU-MIMO on the downlink side was one of the first features to address this capacity issue.

802.11ax is set to become the next major leap in Wi-Fi technology. The last major introduction (802.11ac) has since been complemented by 802.11ad in the 60 GHz band, but, 802.11ax is the technology that will provide performance benefits in the 2.4 GHz and 5 GHz bands. Quantenna was the first to announce a draft-802.11ax-compliant access point radio solution back in October 2016. It was a 12-stream solution with 8×8 in the 5 GHz band and 4×4 in the 2.4 GHz band. They followed it up with a CES 2017 announcement for their mid-range solution (8-stream with 4×4 in the 5 GHz and 4×4 in the 2.4 GHz bands) targeting the same market. Today, Qualcomm has become the second vendor to announce a 802.11ax solution. Unlike Quantenna’s focus on the access point side, Qualcomm is announcing products for both the AP and client device markets.

IPQ8074

Similar to the Quantenna QSR10G-AX, the IPQ8074 is also a 12-stream solution (8×8 5GHz + 4×4 2.4GHz). However, in addition to the baseband, it also integrates a network processor. On the baseband side, the IPQ8074 supports 80 MHz channel width and has MU-MIMO for both uplink and downlink. In addition to the baseband radios, the IPQ8074 also integrates a quad-core Cortex-A53 (running at up to 2 GHz) and a dual-core network accelerator for deep packet inspection and other such applications. interfaces similar to the existing IPQ solutions (for USB and PCIe lanes) are supported. On the network side, a network switch with support for up to four Gigabit MACs is also available. The IPQ8074 SoC also supports NBASE-T, with up to two 10G interfaces supported. The SoC is fabricated in a 14nm processor. Qualcomm expects that access points using the IPQ8074 SoC can be powered via PoE.

QCA6290

The QCA6290 client device platform is a 2×2 802.11ax solution with concurrent dual-band operation. IIt is fabricated in a 28nm process. The platform supports the 802.11ax power saving features along with some proprietary Qualcomm extensions for better battery life. Qualcomm expects the QCA6290 to be integrated into computing systems rather than being a part of a USB WLAN adapter. The QCA6920 interfaces with the host system via a PCIe 2.1 x1 link. Qualcomm didn’t provide us with concrete power consumption limits (such as the 15W PoE budget for systems based on the IPQ8074) for cards integrating the platform.

Qualcomm claims that their proven MU-MIMO leadership experience as well as their expertise with OFDMA / LTE (based on their cellular background) gives them a edge when it comes to 802.11ax solutions. Note that existing networks with 802.11ac MU-MIMO devices can also benefit in a 802.11ax network.

Traditionally, Qualcomm’s main competition in the Wi-Fi space has been Broadcom. However, since the acquisition by Avago, things have been relatively quiet and no 802.11ax solutions have been publicly announced by them. Marvell does have 802.11ax solutions in their roadmap, though they weren’t willing to discuss specifics when I talked to them at CES 2017. In any case, Marvell’s focus has been more on the enterprise space. The main competition (based on announcements from other vendors) is Quantenna’s radio-only solutions. Based on the quotes in Quantenna’s launch release, it appears that they are teaming up with Cavium Networks for the network processor component. This works well in the enterprise space and for specific service provider use-cases. However, most market segments prefer the complete platform (radios and network processor) from one vendor. The platform might be either discrete radios and NPUs or a SoC with integrated radios like the IPQ8074 being launched today. The integration of the radios and NPU into a single chip will definitely make it simpler for router / gateway vendors to bring a product into the market. Another aspect to consider is the unified memory space offered to both the baseband and the network processor in the case of the integrated SoC – as the PHY rates from the radio move beyond the gigabit barrier, this becomes important for the performance and energy efficiency of the system.

From an adoption perspective, it is good to see that both AP and client platforms being launched simultaneously. Qualcomm expects routers based on the IPQ8074 SoC to come to the market before the end of the year. Client devices using the QCA6290 are expected in 2018.
