Left over -

Wifi 802.11

Wireless Systems - contactless: RFID, NFC

- Sensor: ZigBee, BLE, 6LoWPAN

!5

Reason: short range


Short Range Technologies! 802.15.4 standard, with 802.15.5 defining mesh networking

➡ ZigBee ➡ WirelessHART - wired HART (highway addressable remote transducer) - automation

and industrial control ➡ ISA100.11a - International Society of Automation (ISA)

‣ industrial control, adds channel hopping, variable time-slot multiplex options, and mesh networking ➡ 6LoWPAN - Internet Engineering Task Force (IETF)

‣ 128-bit addresses IPv6. Header compression and address translation ‣ compressed packets to fit 802.15.4 packet frames

IEEE family of 802 standards! 802.3 wired Ethernet ! 802.11 WLAN (Wi-Fi) ! 802.15 wireless personal area

networks (WPANs), e.g. ➡ 802.15.1 Bluetooth, ➡ 802.15.3 ultra-wideband (UWB)

technologies, ➡ 802.15.4 low-data-rate WPANs ➡ 802.15.6 is for body area networks

(BAN).

! 802.15.4 low-data-rate, extended life, low power ➡ 802.15.4a/b, basic standards definign

‣ radio technology (PHY) ‣ media access control (MAC) control

➡ 802.15.4c China, 802.15.4d Japan, ➡ 802.15.4e focus on industrial

applications, ➡ 802.15.4f for active (battery powered)

radio-frequency identification (RFID) uses,

➡ 802.15.4g for smart utility networks (SUNs), e.g.Smart Grid.

“Internet had the ability to

dismantle the divide.

Internet failed miserably, the

divide is bigger than ever.”

Kate Gilmore, Human Rights, UNO

“internet light for all” May 2018, Josef NollBasicInternet.org Basic Internet @Basic4all

Digital Inclusion of everyone

● Business aspects ➡ OPEX, CAPEX ➡ Income models?

● Traditional business models are too slow ➡ Mobile broadband roll-out dominated by return on

investment ➡ Premier league, Bollywood outranges non-profit

content

• Providing at least one Information Spot in each village ➡ Internet lite for all - free access to information ➡ Paid access to profitable content - sustainable solution

“Providing Internet to the

basic of the pyramid isn't a

question of affordability, but

rather a question of

sustainability”

Internet Governance Forum, Panel,

“Internet light for all” Feb2018, Josef NollBasicInternet.org @Basic4all

Example of costs! Example: Digital Tanzania

➡ Unconnected: 13 Million people in 4.000 villages

GSM + Wifi ➡ 200W ➡ MicroBTS

Cost: 70 kUS$/village1 USD/month for Telecom

Challenges● Radio coverage

➡ how can we reach Izazi? ➡ what is the expected capacity?

● Business model - (A) fixed line vs (B) mobile hot-spot ➡ What needs to be the price for a voucher? ‣ Time, Amount, Validity

➡ Expense model based on OPEX ➡ Goal: Break-even

3 groups: - 20 min work - 5 min presentation/discussion
