cost effective site engineering
TRANSCRIPT
Is this Kibera from the top of a telco Tower?
Is it from a telco tower with rental costs of $700/month?
Looks like we can cover lots of customers from here
And we’ve got LoS to anywhere from here too!
No! It is not a tower. This is part of the “Cost Effective Plan”
Costs add up fast!These two don’t mix
Let the CEO run a:‘What if’ scenario on his master spreadsheet.
Provide coverage fast and on the cheap
Minimizing OPEX• Minimize CAPEX
• No stub tower costs• No civil works
High OPEX
Towercos look great (well at $700/month they should) Until you need to upgradeNeed to stop our servicesSpending 2 days using 6 men to mount 2 microwave links.
Rental costs $500 to $700We work hard to hand cashover to towercos
Too litte space
Look this height! No Obstruction.Between tower monthly costs of $500 to $700 rentI choose “Cost Effective Plan”
We can use the space as we wantNo lock-in on long term high OPEX Contracts
Oh! That sweet smell of money
“Cost Effective Plan”:
• It will save tower costs, aka handing over our profits to Towercos• Simpler and Fast Distribution Points (DPs) deployment = Fast time
to market• It enables cost effective DP deployments
• Today’s gear weighs very little• A 12-sector distribution point using 30 degrees Horn antennas
has a total weigh 12Kg• A 5GHz rado weighs 500g• A 3x30 degree sector Unit weighs 13Kg.
• A DP using 4xsector Unit weighs 52 Kg
Coverage from Water ReservoirThe Kibera slum, shown on Slide 1, is on the right
We need a site acquisition with the proper assets
Want water pressure?You need to put tank high!
Developing countries have erratic water supplyCommunities build their own water reservoirsThese huge reservoirs can be used to place distribution points.
• It will save tower costs, aka handing over our profits to Towercos
• Simpler and Fast Distribution Points (DPs) deployment = Fast time to market
• It enables cost effective DP deployments
Cities that have water crisis have big tanks there too.

We will install sectors on individual poles around the water tankMetallic tank provide RF insulation between sectors.

Upgrade of a microwave link? Plenty space around.Put a couple of poles. Mount. Align. Test.Hot cutover.Remove old link and their poles.Minimum down time

Water tower is always higher than the top floor
Tank top: Free space for Solar panels never in shade
Water tower is always close to buildings they supplyAC Power is available
No hassle to accessBut safe
Cost Effective Plan:• No stub tower costs• No civil works costs• Only poles U-Clamped to the Tower rails• Antennas isloated from interference by tower tank• Scalable: Can use the whole tank’s perimeter
Once day we can even go PoF: Power over Fiber
costsPoF: Power over FiberBring fiber and power from central location
Cost Effective Plan:• How much does it cost to get a water reservoir?• The same that takes to get a building to deploy of
we serve the community the water tank serves
Towering above everything.
PoF: Bring FiberAnd power from central location
PoF: Bring FiberAnd power from central location
What if we don’t do it?
We cannot compete in the rural and under served
We will spend time and money building roof tops sites
We can continue being robbed by Tower companiesOr we can exploit going Cost Effective
