Projects
My work with Nscglobal has been focused on one major project with smaller projects for other customers spread over the whole period:| Company: | Mars |
| The project: | I've assisted the company to upgrade its WLAN infrastructure to the latest security standarts - Project Management - Meetings, workshops, training sessions - Design of the new WLAN Infrastructure - Integration with existing user directory (Novell eDirectory) - Pilots (5 sites, 12 Cisco WLAN controllers) - Knowledge handover to give the ability to Mars IS teams to deploy the solution by themselves. - I wrote documentations for the customers, the main objective of these documentations was to give them autonomy, they were willing to be able to do the rollout by themselves. Starting without any Wi-Fi knowledge. |
| Products: | Cisco WLC (4400), Cisco 1240 LWAPP (+ H-REAP), Airwave AMP, Cisco WCS, Freeradius, GNU/Linux (CentOS) ... |
| Length: | 18 Months |
| My opinion: | Mars is a global company with a massive WLAN infrastructure (1200+ standalone APs spread over 200+ sites). During a project of this size, the technical aspect of the project is overpassed by most important topics (such as project management). Training and written documentation is a key matter when more than 60 people are involved in the project. This project challenged and improved my organizational skills and my ability to document designs, procedures and to explain technical aspects to non technical people in an international environment. |
| Company: | Sungard |
| The project: | I've designed and implemented a redundant 802.11n draftv2 WLAN infrastructure and an AirMagnet Enterprise IDS/IPS solution. The main objective of this infrastructure was to provide Guest and private VPN access to visitor and employees. |
| Products: | 2x Aruba 3600 (VRRP), Aruba AP-125, Airwave AMP, AirMagnet Entreprise Server, Sensors and Spectrum. |
| Length: | 2 Months |
| My opinion: | This project with a key customer gave me the aibility to work with AirMagnet Enterprise and with the newly released Aruba pre-802.11n draftv2. |
| Company: | Sony SCEE |
| The project: | I've designed and implemented a partially redundant WLAN infrastructure aimed to be used by PSPs and PS3s and offering guest access service to visitors. |
| Products: | 2x Aruba 3400, Aruba AP 65 spread over 4 sites, Aruba MMS |
| Length: | 2 Months |
| My opinion: | High Availability was not the key aspect of this project, the customer was looking for a secured and centrally managed WLAN infrastructure. Finding the best answer to fit security constraints linked to end-user devices (PSP, PS3 ...) keeping in mind the overall security of the WLAN infrastructure. |
| Company: | Intercontinental Hotel Group (IHG) |
| The project: | I've assisted one of my colleague in the design and deployment of an Aruba 3400 WLAN infrastructure (802.11i, Captive Portal, VoIP). |
| Products: | 1x Aruba 3400, Aruba AP 65, Microsoft IAS, Cisco 7921G |
| Length: | 2 month |
| My opinion: | This simple simple deployment include the most common usages of a WLAN infrastructure. Corporate access using 802.11i + EAP-PEAPv0MS-CHAPv2, Guest Access using a captive portal with a VPN passthrough to for some users not registered within the AD and VoWLAN using Cisco 7921G wireless phones. |

Projects
I've worked on lots of different projects with Bluesafe, please find bellow more details about some of them:| Company: | Major French Aircraft and Defense company |
| The project: | I've assisted the company to build its new Wi-Fi architecture. Working with a network architect from this company my tasks were focusing on different topics: - I conducted VoWLAN-oriented Site Surveys, the objective was to plan a complete coverage of each location of the company to provide Voice over WLAN (VoWLAN) capabilities. The targeted Wi-Fi phone was the Cisco 7921G. - I assisted the company to test a lot of different scenarios and advanced features of the Cisco WLC controllers (such as LOCAL EAP, Mobility Anchors, ...). During the year this project has been extended to the wired part of the network. The objective was to provide the same kind of security than 802.11i. I've done testings on 802.1X, PACL, VLAN MAP, Per User ACL (sent through Cisco ACS), Guest VLAN, ... - I wrote documentations for the customers, the main objective of these documentations was to give them autonomy, they were willing to be able to do every appliance integration by themselves. Starting without any Wi-Fi knowledge. |
| Products: | Cisco ACS, Cisco WLC (3750G), Cisco 7921G Wi-Fi Phones, Cisco 1240 LWAPP, Cisco WCS, Cisco Switches (3560, 3750G, ...), Airmagnet Analyzer, Airmagnet Survey, Freeradius, Apache, LDAP, OpenSSL, GNU/Linux (CentOS), Squid, iptables, ... |
| Length: | Two months spread over one year |
| My opinion: | This project (which took me nearly two months spread over the whole 2007 year) was extremely interesting, it gave me the ability to analyse a deployment from the studying/draft process to the final installation and testing. For my company this project was initially a small Wi-Fi site Survey contract and has moved (by the addition of other projects) during the year into one of our major contract for the 2007 year (service + hardware furniture). The "pilot" of this project has been successfully deployed and the migration process has begun for the whole company. |
| Company: | Direction des Journaux officiels (French government) |
| The project: | I've installed a WLAN and a Workspot within the company, I've then taught the customer how to maintain its new Wi-Fi infrastructure. Finally I've written documentation about this installation and its maintenance. |
| Products: | Bluesocket (BSC 2100), Freeradius (authentication request on the Microsoft AD). |
| Length: | 5 Days |
| My opinion: | This small project (10 Access Points) gave me the opportunity to work for the french government, the company has used this project to test the reactivity and the dynamism of Bluesafe on this kind of project. Bluesafe has then won a contract concerning the installation of a workspot within one of the most important place of the french government, with more than 600 Wi-Fi accounts. |

| Company: | GMF |
| The project: | I've taught the customer how to install and maintain Aruba Wi-Fi appliances according to their needs and constraints and I've written documentation about these topics. |
| Products: | Aruba 200, Aruba 800, Microsoft IAS, ... |
| Length: | 5 days (3 days teaching, 2 days writing documentation). |
| My opinion: | Such projects aimed to give autonomy to customers with their Wi-Fi infrastructure are very interesting. This kind of lessons usually provided to 3-5 people gave me the opportunity to work on my adaptivity to different people with different technical background, and really often no Wi-Fi background at all. The result of these project is quicly measurable by the ability of the customer to install their own Wi-Fi infrastructure by themselves. |

| Company: | Major French technical University (multi-site) |
| The project: | I've taught the customer how to install and maintain Aruba Wi-Fi appliances according to their needs and constraints and I've written documentation about these topics. |
| Products: | Aruba 2400, RAP, GNU/Linux, Freeradius |
| Length: | 9 Days (6 days teaching, 3 days writing documentation). |
| My opinion: | This project, similar to the GMF one, was a lot more interesting because the integration of the solution has a lot more problematics like eduroam (www.eduroam.org), remote Access Points (RAP), ... The three persons I was working with had strong technical background so we've been able to practice advanced configuration capabilities of Aruba controllers. |
| Company: | Disneyland resort Paris |
| The project: | Wi-Fi coverage of the whole resort park |
| Products: | Airmagnet Analyzer, Airmagnet Survey, Wi-Fi Site Survey Kits. |
| Length: | 20 days |
| My opinion: | The main challenge of this project was not the Wi-Fi site survey itself, organisation and methods were extremely important to successfully complete the site survey of nearly 150 different locations during the 12 days period planned within the park. |
