As we can see our mobile service today has equipped with the latest technology embodied. Application like MMS, email , mobile web browser (firefox), video call, Fixed mobile convergence (FMC), mobile extension, could deliver easily via 3G. Everybody could run all of these application as long as they are within 3G coverage. Limited coverage right?…. Well after the GPRS (40kbps) evolve to egde (300kps) , then to 3G (2MBps) , and then HSDPA (36Mbps), the next generation (4G) of mobile network would run at least 300Mbps. Using what ?…They call it as Worldwide Interoperability for Microwave Access (WiMax).
Since the first idea, WiMAX has the potential to replace a number of existing telecommunications infrastructures. In a fixed wireless configuration it can replace the telephone company’s copper wire networks, the cable TV’s coaxial cable infrastructure while offering Internet Service Provider (ISP) services. In its mobile variant, WiMAX has the potential to replace cellular networks. But in Telco, we would call it as mobile WiMax. Mobile WiMAX takes the fixed wireless application a step further and enables cell phone-like applications on a much larger scale. For example, mobile WiMAX enables streaming video to be broadcast from a speeding police or other emergency vehicle at over 70 MPH. It potentially replaces cell phones and mobile data offerings from cell phone operators such as EvDo, EvDv and HSDPA. In addition to being the final leg in a quadruple play, it offers superior building penetration and improved security measures over fixed WiMAX. Mobile WiMAX will be very valuable for emerging services such as mobile TV and gaming.
The technologies used to build this huge trunk highway are Orthogonal Frequency-Division Multiplexing (OFDM) and multiple input & Mulitple output (MIMO). OFDM & MIMO have emerged as the technologies of choice to satisfy this growth, not only for WiMAX (802.16e & 802.16m), but also for 3GPP’s future LTE standard as well as Wi-Fi (802.11n). The combination of OFDM and MIMO is highly scalable and systems based upon it are best positioned to satisfy the headroom requirements for mobile broadband data over the next decade.
Then, how will it give benefit to IIUM environment ? Well.. the fast growth of MIMO technology will enable IIUM to become fully wireless campus territory. With the existing aruba Network environemt , and additional deployment of out-door antennas, which decrease in quantity , but will increase about more than 50% coverage by using MIMO technology, this dream would become true. The existing coverage, which cover only for kulliyyah and admin building, would be expendable to Mahallah area, and also all other coverage with lesser amount of budget.
The other application like video conference, In-house video streaming, or in-house IIUM TV program , which require great bandwidth, will be easily adopted with the existence of great warrior of IIUM mobile WiMax. As for the mobile application, the mobile VoIP (SIP enabled mobile phone) could be used as to greatly lower down the call billing among the IIUM Community. Integration with call routing will also decrease the charge from local to adjacent call and other nation wide call billing. Is it really a great ROI? In fact, yes for long term benefit. The continuous educational program will last forever as the infrastructure has tremendously being develop in advanced for better future people development.
