Mobile Networking
- Cellular Technologies
- Mobile communication can use cellular towers which have a range of over 17 miles.
- Cellular WAN has developed several standards to handle data traffic.
- Mobile protocols include:
- HSPA–3G,
- HSPA+–4G,
- and LTE.
- WiMax–extension of Wi-Fi networks; uses the 802.16 standard for more range than the 802.11 standard.
- HSPA (High Speed Packet Access)–single Mbps range 3G technology.
- HSPA+–multiple Mbps range; considered a 4g technology.
- LTE–ten’s of Mbps range; 4G technology.
- Tethering–using the cell phones signal to get other devices online.
- Can be wired or wireless (hotspot).
- Mobile Connectivity
- ANT/ANT+ are used for health applicances (e.g.-monitoring; workout equipment; heart-rate monitors; watches), run in 2.4GHz band, range is 20-30 meters, & speed 20kbps.
- NFC allows for very close-range data transfer range (4cm) with a transfer speed of 424 kbps; 13.56MHz.
- IR is a technology that uses infrared light, 1+ meter range, transfer speed of 1 Gbps, requires line-of-sight.
- Infrared uses light; not radio.
- 1+ meters; 1 Gbps; Line-of-sight.
- Home Automation–Z-wave & Zig Bee;
- Z-Wave 900MHz; 30 meters; 9600bps.
- ZigBee 2.4GHz; 10 meters; 250 Kbps.
- Bluetooth–2.4GHz; 100 meters; 3Mbps.
- RFID (Radio-Frequency Identification)–passive device uses radio power to turn it on.
- packaging, luggage, tracking, etc.
- 20KHz-10GHz
- 10cm-200meters
- Speed is not important because it does very little data transfer!
- Deploying Mobile Devices
- Mobile devices are prolific & very useful in both personal & corporate environments.
- Be familiar with the deployment models discussed and what the pros & cons are of each.
- Consider mobile device management for privacy & productivity.
- Mobile device management tools vs. mobile application management.
- COBO–(Corporate Owned, Business Only)
- COPE–(Corporate Owned, Personally Enabled)
- CYOD–(Choose Your Own Device)
- BYOD–(Bring Your Own Device)
- Mobile Access Control
- Mobile access management must consider how to allow BYOD devices to access a network.
- Mobile on-boarding is the process of making a network available to BYOD mobile devices, one standard is a captive portal sign-in page.
- In a SOHO router, access control can be decided using white-listed or black-listed MAC addresses.
- NAC (Network Access Control)
- Mobile NAC
- for Enterprise routers–On-boarding (captive portal) anti-malware; Geo-fencing
- for SOHO routers–Allow access via MAC addresses (MAC filtering , whitelisting & blacklisting)
- Note: 2-Factor authentication is NOT a component of Mobile NACs. 2-Factor is generic and can apply to a standalone system as well as a network.
