Re: WiFi courses/vendors recommendation

If he's wanting to make a "metro/muni/variousterm" "wireless" network though, he's very likely not going to be using "Wi-Fi" at all. Sure, many of the products may have a WiFi PHY layer, but for outdoor PtMP environments you're talking TDMA, not CSMA.

He would be better served by some RF Engineering and vendor specific courses, IMO.

(Just my $0.02 as having spent quite a bit of time in the WISP industry, who has watched these "metro/muni/variousterm" networks die over and over and over again.)

With respect to vendor neutral training I would suggest starting with CWNP
@ www.cwnp.com.

They specialize in providing vendor-neutral Wi-Fi training and
certification.  Instructor led training is available via certified training
partners.   In addition, there are study guides available for purchase.
CWTS (lvl 0) - Intro - terms & lingo
CWNA (lvl 1) - Wi-Fi 101
CWSP (lvl 2) - Wi-Fi Security
CWDP (lvl 2) - Wi-Fi Design
CWAP (lvl2) - Wi-Fi Protocol Analysis
CWNE (lvl3)....

I recommend completing some or all the CWNP training to understand how
Wi-Fi works.  Once you understand how Wi-Fi works, you'll know how to
design and configure a network to meet your design goals.  Next, complement
your vendor neutral training with applicable vendor specific training to
understand their interface and specific nuances.  Moving to another vendor
is just a matter of learning where the nerd knobs are for configuring their
product as you'll already know the fundamentals of Wi-Fi.


Kindest regards,
Troy

Doubt how much PoE you'd use for the MetroWifi stuff, but for the
"small/medium events Wifi coverage":

  Ubiquiti Networks.
Its cheap and it works great. Support sucks though.

Just watch it here if you're expecting to plug UniFi APs into standard
802.3af/at ports and get power.  When I last interacted with them
(customer
equipment; year or two old, I believe) a lot of their WAPs are 24V, not
802.3af/at.

Only their UniFi AP & AP-LR are 24V, all the rest of their product line
(AP-PRO, AP-AC as well as the outdoor units) are 802.3af or 802.3at
compliant.
You can easily overcome this limitation by using their 8-port ToughSwitch
were each POE port can be configured to either 24V or 48V.
IMHO Ubiquity's UniFi is a very decent solution when you want to keep
budget low.
