• 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

• A8 base station has both a wired Ethernet port and a 5 GHz wireless backhaul for connection to the backend network.


• 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

• With 250m base station separation, 70% of indoor coverage can be achieved. Outdoor street level WiFi repeaters are installed in blind spot in coverage area to enhance the indoor coverage to 95%.

• A2 will be used for point-to-point (PTP) wireless bridge which connects an A8 to a remote wired Internet outlet.


• Multiple A2-A8 PTP pairs can be grouped together to form an A8 cluster. In the figure below, three dedicated 802.11a paths are formed with total throughput of 3 x 20 Mbps available.


• Distances between various combination of A2 and A8, using different panel or omni antennas are :

• 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


• Antlab SSG will functions as the target Radius server for all the 802.1x wireless access points, including EAP-SIM.


• 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.


• The ANTlabs SSG provide authorization service such as :– User provisioned routed IP. – Upload bandwidth rate limit. – Download bandwidth rate limit.– Firewall rules.

• The accounting services will track usage of the service. Based on the duration user is logged in 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
