Chipset Vendors: Broadcom
Broadcom is the wireless and broadband component manufacturing industry's leader. Its undisputed strength lies in its transceivers and radios, which are even used in conjunction with competing router SoCs.
Broadcom Router SoCs
Introduced in 2013, the StrataGX BCM5862X series is part of Broadcom’s Northstar Plus family, featuring single- or dual-core ARM Cortex-A9 processors at 1.2GHz. They connect to two transceivers via PCIe, and are designed for 5G Wi-Fi in combination with capable transceivers. With two SATA 6Gb/s interfaces, a cryptographic accelerator and fast memory, the BCM5862X series is intended for storage appliances.
The BCM5301x and BCM470X lines brought 802.11ac-specific support to the Broadcom portfolio in 2012. The 5301x is the enterprise/small business version of the 470x series suitable for residential routers and gateways, and both are manufactured on a 40nm processes. The 4709/AO/CO chips succeeded the popular 4708 series; the AO model was released in 2013, followed by a base model in 2014. The newest member of the family, the BCM4709CO, came out in 2015 (and is also listed as the BCM47094).
Broadcom's latest and greatest for "affordable and mid-tier" residential/small-business routers, the BCM47189 and the BCM53573, were introduced in January 2015 at CES. They are (probably) meant to be paired with the BCM4366 5G Wi-Fi 4x4 MU-MIMO transceiver (radio) chip. Broadcom also announced its enterprise- and cloud-oriented SoCs from the same family, the 43465/43525 and the 47452.

An ADSL router SoC, the BCM6318 is designed for integration with entry-level networking devices, providing an all-in-one solution for turnkey router development.
Another integrated modem/router solution with an external wireless NIC, the BCM63268, is one of the most widely used chips for xDSL platforms. It is designed to work in conjunction with the BCM2057 radio. The 63168 provides VoIP support (multi-channel HD voice) and is designed for use with the BCM4360 5G Wi-Fi transceiver.
The BCM4706 sits right at the edge of obsolescence, but a number of popular, low-end routers from 2012 and 2013 use this chipset. Its dual PCIe interfaces are designed to pair with a BCM4331 802.11n 3x3 Wi-Fi transceiver, and it operates both in selectable and simultaneous dual-band configurations.
The BCM4352, BCM4360, BCM43526 and BCM43516 were a family of Gigabit 5G chips introduced in 2012 meant for the consumer market. They differ mostly in nominal speeds; the BCM4360 is the fastest, at 1.3 Gb/s via three streams, the BCM4352 and BCM43526 offer two streams at 867 Mb/s and the BCM43516 comes in last, providing 433 Mb/s. The BCM43526 comes with USB instead of a PCIe interface and targets set-top boxes and televisions. The BCM4360 is widely used in wireless routers like Asus' RT-AC56S and RT-AC56U; D-Link's DIR-860L; Linksys' EA6200, EA6300 and EA6350; and Netgear's D6200, EX6200 and R6200, among others.
The BCM43131 is a Wi-Fi chipset from 2013 with PCIe interface and support for Wi-Fi standards 802.11b, 802.11g and 802.11n. Equipped with a BCM2057 radio chip, it is used in wireless routers from Tenda, namely the D152, W150D v6 and W311E.
An earlier incarnation of this chipset, the BCM43217 (2012) is equipped with the BCM2055 radio, and supports b/g/n. It was used in wireless routers from a number of vendors, including Asus' RT-AC56S and –U; Belkin's F9K1113 and 1118; Linksys' EA6200, EA6300, EA6350 and EA6400; and Netgear's DGN2200, R6200 and R6250.
Introduced in 2014 as a 3x3 MIMO 802.11ac chip for routers, the BCM43602 is equipped with a 320MHz single-core processor and comes with a PCIe interface. Broadcom rates its peak performance at 900 Mb/s. The chip has been used in multiple routers, including Asus' RT-AC3200; the Linksys EA9200; Netgear's D7000 and R8000; and the TP-Link Archer C3200.
Announced in January 2015 as Broadcom's then-fastest 4x4 MU-MIMO chip, the BCM4366 is a 5G radio unit meant to be used in high-end consumer devices. The BCM4366 comes with an 800MHz Cortex-A7 processor. Its Wi-Fi speed is a nominal 5.4 Gb/s (in theory, since, in practice, most consumer devices are unable to saturate it). More important is the MU-MIMO capability, allowing the BCM4366 to handle up to eight clients simultaneously. The radio spans 160MHz, which, unfortunately, also means that only two such networks fit in the 5GHz band without overlap.
