STATUS

see diagrams, maps.

Summary:

  • Existing 1G (multi mode) fiber network on campus
  • 20M uplink through ZAMREN, single mode fiber
  • Layer 3: existing network flat on on /24 network
  • Routing: they have 3750 G12s with 12 ports, all used - and they have one spare
  • NSRC offers to send one more 3750

Main Goal

  • Create edge access network
  • 2000 concurrent users expected
  • "Coverage": 5 km Radius
  • Precondition: sane wired network, Core Router, IP plan

Main objective of 4 day workshop/DEA

  • Create first examples of edge access network
  • Start building in-house capacity to continue and complete network

Wireless / License conditions

"2.4GHz (2400-2499MHz) and 5.8GHz (5800-5899MHz) are available as "unregulated" frequency range. my understanding is one do no need license to transmit or get protection from interference. also no spectrum license fees applied." BS

Power

"Generally available but has significant number of short 1-2hours outages (but also dependent on ones locations in town, if not high priority like hospital etal can be long anywhere from 2-8hours). which means it warrants use of battery backup of 4-6hours in any planning" BS

better still: battery and solar panels

Preparation work steps

  • HW: type approval needed? Steve talks to ZICTA about it. Dickson will check with ZICTA.

  • Layer 3: IP architecture, currently one flat 10.10.15.0/24
  • Do they have the resources to build a core router and start subnetting?

Notes from 23 May prep call

Planning call 23 May 08:00 PDT for Copperbelt University DEA

Background ~

The Copperbelt University has a flat network with ~ 600 hosts in a single broadcast domain. An additional 2000 wireless clients are expected. The only router on the campus is for the uplink (core router) and all the ports are fully populated. All fiber on the campus is multi-mode (the uplink to the ISP uses single-mode). IP addresses are currently being statically configured (no DHCP).

For placing access points we'll use exisiting fiber and where there is not, we'll deploy a wireless point2point link with ubiquity radios.

Plan

We will provision a VLAN on the campus network for the wireless segment and use a captive portal for access control and dynamic address assignment (DHCP). Access points (Ubiquiti Unifi Pro) will be using the 2650-PWR POE switch to provide power where possible.

Action items ~

o Hans will ship a Cisco 3750, stacking cables, 2 picostations, and 2 nanostations to Kitwe. SFPs will be brought in Hans' hand carry luggage

o Sebastian and Dickson will work on provisioning the linux server for the captive portal and ubiquiti controller

o Dickson will stack and configure the 3750 from NSRC when it arrives

o Steve will check with ZICTA on whether the ubiquiti gear is allowed to be imported to Zambia for deployment

o Dickson will send a map with target buildings for wireless deployment indicated. We discussed the hostels and the library as potential targets.

o Dickson will provide a spool of cat6 cable, plugs and 2 crimping tools.

o Dickson will put us in contact with someone who can arrange transportation from Lusaka to Kitwe and also find lodging for the team.

Anything else?
