Mac & 10Gbps Internet

Background knowledge

  • 1 Byte = 8 bits
  • 1 Byte per second (BPS) = 8 bits per second (bps)
  • 40 Gibabit Ethernet (40GBASE-T)
  • 10 Gigabit Ethernet (10GBASE-T)
  • 1 Gigabit Ethernet (1000BASE-T)
  • Thunderbolt 3 up to 40 Gbps
  • You also need Cat 6 / Cat 6a / Cat 7 / Cat 8 cable 1
  • 2.4GHz — Slower (compare to 5GHz) but better wall penetration. About 1200 Mbps.
  • 5GHz — Faster but weaker wall penetration
  • Mesh — Multiple Wi-Fi routers that make up a network
  • MacBook Pro (as of 2020)’s WiFi is 802.11ac (Wi-Fi 5)
  • Wi-Fi 5 = 802.11ac
  • Wi-Fi 6 = 802.11ax
  • iPhone 11 Pro & 11 Pro Max, SE (2nd Gen): 802.11ax
  • iPhone X, XS, SE: 802.11ac

How you Connect

Internet Provider ----> [  WAN -- LAN  ] ----> Laptop
                          Wi-Fi Router   - - > Laptop

---->: Cat 6, 6a, 7 Cable
- - >: 2.4GHz, 5GHz Wi-Fi signal
Laptop: MacBook Pro

Ethernet Adapter for Mac

They are about $200-$350. They connect this way: 10GBaseT -> Thunderbolt 3.

Sonnet Solo 10G

Akitio T3-10G

Akitio Thunder3 Dock Pro

CalDigit Connect 10G
Also works for Windows.

OWC Thunderbolt 3 10G Ethernet Adpater

QNAP: Thunderbolt 3 to 10GbE Adapter (QNA Series)

Wi-Fi Routers

802.11ax (or Wi-Fi 6) up to 9.6Gbps.

You want a WAN and LAN both supports 10Gbps. Currently this is the only one for me in Japan:

WXR-5950AX12 by Buffalo
5GHz up to 4804 Mbps
2.4GHz up to 1147 Mbps

LAN Cable 101

Less
Flat cable — looks better
Normal (round) cable - better anti noise
Longer distance - Single core
Shorter distance - Twisted core

CAT5  ANSI/TIA/EIA-568-B.1
CAT5e ANSI/TIA/EIA-568-B.2
CAT6  ANSI/TIA/EIA-568-B.2-1
CAT6A ANSI/TIA-568-B.2-10
CAT7  ISO/IEC 11801
CAT7A ISO/IEC 11801
CAT8  ANSI/TIA-568.C-2-1

Speed

Type Speed Frequency
CAT5 100MB 100MHz
CAT5e 1Gbps 100MHz
CAT6 1Gbps 250MHz
CAT6A(6e) 10Gbps 500MHz
CAT7 10Gbps 600MHz
CAT7A 10Gbps 1000MHz
CAT8 40/25Gbps 2000MHz

The Hz means the range of sending data are wider (good).
CAT 8 has better noise
