14. • A8 will be used for primary outdoor coverage. (horizontal beamwidth : 70-degrees and vertical
beamwidth : 12-degrees)
– NLOS coverage radius of 350 to 500 m across the sub-urban areas where the buildings are
relatively low-raised
– Dense-urban areas with high-raised buildings, the coverage is highly dependable on the
building and street structure, a 250 m NLOS coverage radius along a street.
– Outdoor open areas such as park, A8 can provide a near LOS radius of up to 1 km or more
Environment Coverage Radius (r) Coverage Area (2r2) No. of A8/ km2
Open area (near LOS) 1000 m 2 km2 0.5
Rural (NLOS) 500 m 0.5 km2 2

16. • A8-Ei can be used for outdoor coverage instead of A8 in the following circumstances:
– The maximum target coverage radius exceeds that of the A8 or the coverage areas are in long sector
shape, e.g. along a street, airbase coverage, long range wireless DSL.
– Coverage to a remote discrete area separated by highway or sea at distant away exceed that of A8, e.g.
island, offshore oil refining telemetry, coverage for tourist boats at middle of a lake
– Higher link budget is desired where higher received signal strength is necessary, e.g. indoor penetration,
support VoIP
– Larger site coverage area at the same user capacity than that of A8 is desired, e.g. rural residential area
with large footprint and low population density

23. • Backhaul Throughput (throughput requirement under each A8 in the interested area)
– Throughput per user = 1 Mbps (assumption)
– No. of concurrent users per A8 in dense-urban areas = 100 concurrent users (assumption)
– Share ratio = 25 (assumption)
– Backhaul throughput per A8 in dense-urban areas
= No. of concurrent users per A8 x Throughput per user / Share ratio
= 100 concurrent users x 1 Mbps / 25
= 4 Mbps

24. • Antlab SSG will functions as the target Radius server for all the 802.1x wireless access points,
including EAP-SIM.
24 | © 2010 3D Networks. All rights reserved.

25. • The typical authentication process:
– Mobile client tries to associate to the Wi-Fi access point (AP), sends an EAP authentication request that
is picked up by the AP.
– The AP then translates the EAP request into a Radius Access-Request packet (with EAP-SIM based
extensions) and sends it to the SSG (which acts as a Radius Proxy).
– The SSG proxies this Access Request to Tru’Auth which interprets the request as an EAP-SIM request
and initiates its own authentication request to the HLR via the MAPS gateway, using the IMSI that is
found in the Radius Access-Request packet.
– The MAPS gateway queries the appropriate HLR and retrieves the triplets associated with that IMSI
and passes the information back to Tru’Auth.
– Tru’Auth then generates a MAC (message authentication code) challenge based on the triplets
received and this is sent all the way back to the mobile device.
– The mobile device reviews the challenge and if valid, returns its own MAC based on its own SIM card to
Tru’Auth.
– Tru’Auth will verify the returned MAC and if valid, return a Radius Access Accept packet back to the AP
and the AP will then allow association to the mobile device.

– User provisioned routed IP.
– Upload bandwidth rate limit.
– Download bandwidth rate limit.
– Firewall rules.

and the amount of traffic (input / output octets and packets)
• Advanced integrated traffic management capabilities
– Volume Prepaid and Fair Use
– Multi-tier QoS with bandwidth guarantee
– Application-based traffic prioritization
