Overview

 * On the BT Shop
 * GPL Code for the Home Hub 5 (and other Home Hub models)

The Home Hub 5 is a simultaneous dual-band wireless-AC CPE with an
 * integrated VDSL2 modem, a GbE WAN port, and four GbE LAN ports.

"RTV7505W-D18 (ROHS) REV:4.10" is silkscreened on the board in the images.
 * HannStar seems to be the PCB manufacturer.

Plusnet started shipping an (internally) identical unit in a white case branded
 * as the "Plusnet Hub One" to fibre customers in November 2015.

BT Home Hub
 * BT Home Hub 5 (Type A) - CPU: Lantiq PSB 80910 (XWAY VRX268)
 * BT Home Hub 5 (Type B) - CPU: Broadcom BCM63268 @400MHz

Power consumption
Model		BT Home Hub 5A	BT Home Hub 5B In operation		9.2W		14.0W Idle			6.3W		7.2W Standby mode		0.2W		0.1W

SoC
Per the VRX268 product brief, the VRX268 SoC has an internal GbE switch
 * SoC: Lantiq XWAY VRX268 (PSB 80910 EL V1.2) MIPS 34Kc
 * w/ two internal Ethernet PHYs (each functioning as either a single GbE PHY
 * or dual FE PHY) and support for three external PHYs via MII/RMII/RGMII.
 * This unit is using three external GbE PHYs (PEF7071V)
 * and the two internal GbE PHYs with the in-SoC switch.

The CPU/SoC and both wireless chips are all supported by OpenWrt.

Wireless
The wireless radios used are the following...
 * Atheros AR9227 - 2T2R 2.4GHz, 802.11bgn (300Mbps)
 * w/ 2x Microchip SST12LP15A - High Power 2.4GHz Power Amplifiers
 * 2x internal antnenae, inline Hirose switching coaxial RF test connectors


 * Qualcomm Atheros QCA9880 - 3T3R 5GHz, 802.11ac (1.3Gbps)/n (450Mbps)
 * w/ 3x Skyworks SE5003L1 - High Power 5GHz Power Amplifiers
 * 3x internal antnenae, inline Hirose switching coaxial RF test connectors.

The device has surprisingly long range at 5GHz thanks to the SE5003L1
 * high-power amplifiers/front-ends.
