Saatnya berpindah ke 802.11n

802.11n for Midmarket BYOD: Why now?
⁠

We're in the midst of an incredible megatrend. We know it and we're living it. We all love our mobile devices; whether it's our laptop (yes, I'm sitting at my kids swim class typing away for work), our mobile phone (I'm getting texts on what's for dinner), or our tablet (where Draw Something awaits me). Apple recently stated that they have sold more than 67 million iPads in the recent 18 months. That is more than all the Mac sales in the past 27 years. There's no denying it:  we are in the midst of an incredible megatrend—a mobile megatrend.

But what does this mean to businesses?From the IT perspective, the role of the mobile devices has transformed from a luxury item used for personal communication and entertainment to an integral tool for employee productivity. Mobile devices are now the main platform for work (laptop or tablet) and the primary medium for corporate contact (mobile phone). With employees bringing an average of two mobile devices each (laptop/tablet + mobile phone), companies can reap the benefits of new business opportunities and more productive employees.

Sound good? There's a caveat. In order to harness all that potential, you have to overcome the Bring-Your-Own-Device (BYOD) challenge: you need reliable, pervasive wireless coverage to ensure the wireless bandwidth and link-reliability required to support the increased number of mobile devices in the workplace.

So you're the IT administrator for a mid-sized company and you're thinking, "But I already have wireless coverage. I'm covered, aren't I?"

Consider a medium sized business with a legacy 802.11a/b/g wireless infrastructure and an average of two mobile devices per employee. In this scenario, each device is sharing 802.11a/g's 54Mbps bandwidth per access point. What's worse, 802.11b access points only supports 11Mbps. How are you going to provide the necessary connectivity required to support the proliferation of mobile devices in your workplace when you're limited by bandwidth?

It's time for Mid-market to move to 802.11n. From a pure numbers perspective, an entry-level 802.11n 2x2:2 access point supports 300 Mbps. That's a 6X boost in network performance with 802.11n. The best part is that 802.11n can support a mixed client environment; supporting a mix of 802.11a/b/g/n clients.

Let's take a quick look on the impact of 802.11n on different market segments:

Education: Take a classroom or lecture hall full of students with one mobile device each, sharing 802.11a/g's 54Mbps bandwidth per access point. Even if students are only using 2Mbps each, the bandwidth for classroom collaboration applications is limited to supporting fewer than 30 students. An 802.11n access point would support increased bandwidth and more students with its 300Mbps.

Healthcare: Imagine a mid-size medical group's key medical personnel trying to keep critical communication over a shared 802.11a/g's 54Mbps bandwidth per access point. Slow or unreliable connections are not acceptable. With 802.11n, link reliability and bandwidth availability would be more assured. Additionally, the additional increase in available bandwidth would provide patients with wireless guest-access as a service and encourage deployment of additional applications, such as digital records in patient or diagnosing rooms.

Corporate Businesses: Imagine a medium-size real estate, technology, financial services, or other medium business with each employee using a laptop and a smartphone on the wireless network, sharing 802.11a/g's 54Mbps bandwidth per access point. This worked fine when employees were tied to their desks, leveraging their wired port. 802.11n, with increased bandwidth and stronger link reliability, would enable employees to stay connected on-the-go, increasing productivity and collaboration in hallways, conference rooms, break rooms, and offices.

Retail: Think Apple store with their employees walking around with their mobile point-of-sale devices. There's no question that leveraging these point-of-sale devices is feasible over 802.11a/g's 54Mbps bandwidth per access point. 802.11n would enable new and flexible ways to do business. Furthermore, mid-market businesses could take advantage of the additional bandwidth to encourage more users on the network to benefit from rich applications, such as location-based services to push specials to the end customer.

In addition to providing the necessary bandwidth to leverage the BYOD trend, 802.11n provides the additional upside of reliability. With the introduction of 802.11n a few years ago, came the insertion of MIMO (multiple-in-multiple-out). MIMO ensures a greater SNR (signal to noise ratio), enabling a more reliable transmission and a stronger transmission signal. On one end of the spectrum, the same data stream is transmitted over multiple antennas. This data stream takes multiple paths to the multiple receivers. The receivers now mathematically combine these multipath signals to result in a single optimal receive signal overcoming interfering noise and ensuring link reliability. On the other end, we have each transmit antenna transmitting a different stream of data, optimizing the full bandwidth potential. Leveraging the combination of these spectrum ends, 802.11n provides increased reliability along with increased bandwidth.

802.11n inherently offers a better mobile experience than the legacy infrastructure with:

Increased 300 Mbps per access point bandwidth to support an increased number of devices

Greater availabggility of bandwidth to connect more users to the network

Improved link reliability to ensure optimized connectivity

New opportunities for increased service features and new revenue streams

We're in the midst of the BYOD megatrend, and a strong wireless network is required to tap into new revenue opportunities and increase productivity. There is no better tool for this than 802.11n wireless technologies to ensure performance, reliability, and scalability. Mid-market businesses can leverage 802.11n network performance simply, affordably and securely with Cisco's Mid-market BYOD Solution. Check it out.

ManageEngine ServiceDesk Plus Launches Project Management Beta

New Module Debuts at LEADit 2012 in Australia;
Unifies Service Desk and the Project Management Office

New ServiceDesk Plus features: project milestones and tasks integration, task planning management, effort estimation, Gantt view, and cost calculations

Meet ManageEngine at LEADit 2012 in booth #S5

LEADit 2012

PLEASANTON, Calif.--(BUSINESS WIRE)--ManageEngine, the real-time IT management company, today announced the beta version of its Project Management module for the company's ITIL-ready help desk software, ServiceDesk Plus. Available immediately, the Project Management beta module is designed for different teams and experts to collaborate in managing help desk projects of any size. With the ability to split a project into different milestones — and milestones into numerous tasks — ITSM team members can manage and track tasks from start to finish.

e today's announcement at LEADit 2012, the 15th Annual National Conference of itSMF Australia, running August 20-22 at the Gold Coast Convention Centre in Queensland. A silver sponsor of the show, ManageEngine will be demonstrating ServiceDesk Plus and the Project Management beta module in booth number S5.

"The Project Management module in ServiceDesk Plus breaks down the project and service silos. Now, ServiceDesk Plus provides IT organizations with an integrated solution that gives them provisioning access to resources, which fosters the frictionless delivery of IT services."

.

Making Large Projects in IT Departments Manageable

IT companies today face significant challenges in supporting operational processes and service management as individual, isolated activities. As an IT department scales up, it needs an integrated tool to manage large projects and implementations. Otherwise, individual projects may become silos of activity that inadvertently change configuration items and adversely impact related, critical applications or services.

"The need of the hour is the convergence of service desk and project management for large projects in IT organizations," said Uma Shankar, director of product management at ManageEngine. "The Project Management module in ServiceDesk Plus breaks down the project and service silos. Now, ServiceDesk Plus provides IT organizations with an integrated solution that gives them provisioning access to resources, which fosters the frictionless delivery of IT services."

The Project Management module in ServiceDesk Plus serves as the implementation tool to carry out IT changes identified in the application's Change Management module. The Project Management module helps administrators and project managers create milestones and tasks on new projects and assign resources based on the requirements and availability.

The Project Management module can perform feasibility checks by cost estimation and resource management. In addition, the module tracks all the changes made and tasks completed through the help of a Gantt chart and Calendar View, and it documents the projects implemented in IT.

The advantages of service desk and project management fusion are highlighted in the recent webinar, "The Convergence of the Service Desk and the Project Management Office." Featuring Charles Betz, research director of IT Portfolio Management at Enterprise Management Associates, and hosted by ManageEngine, the webinar shares insights, use cases and best practices for combining these two functions. A replay of the webinar is available at http://ow.ly/d2Gmg.

Pricing and Availability

The beta version of the ServiceDesk Plus Project Management module is available immediately, free of charge, for customers of ServiceDesk Plus Enterprise Edition. The production version of the Project Management module will be generally available later this year and will also be free for ServiceDesk Plus Enterprise Edition customers.

IT service management and automation

IT Service Management AND Automation: Now That's A Double Whammy Of Business-Enabling Goodness

By Stephen Mann

Blog post body

A recent Forrester report [2] helps IT infrastructure and operations (I&O) leaders understand the business and IT impact of service management and automation (SMA). While both IT service management (ITSM) and automation can be used effectively in isolation, I&O organizations should be seeking to use them in tandem for an "amplified" business impact.

The General Benefits Of Service Management And Automation

The general benefits of SMA can be divided between the I&O organization and the business, though these benefits often overlap:

While SMA is much more than the adoption of IT infrastructure library (ITIL), the ITSM best practice framework, thinking and processes — ITIL's benefits are quite reflective of the general benefits of broader SMA. In a survey of 491 members of the USA chapter of the IT Service Management Forum (itSMF), Forrester found that organizations which adopted ITIL experience the following benefits:

• Improved staff productivity that allows the business to become more competitive (85%).
• Heightened quality of service that improves business uptime and customer experience (83%).
• Reduced operational costs to reinvest in new and innovative initiatives (41%).
• Improved reputation with the business (65%).

The Benefits Of Automation

Cloud computing and DevOps are accelerating the evolution of automated service management, with service management itself evolving to adapt to automation. There is a symbiotic relationship between these movements. Neither cloud computing nor DevOps is truly feasible without extreme automation, and automation needs the economic force of movements like cloud and DevOps to compel the market investment necessary to deliver capable technology solutions. It's becoming increasingly obvious that service management in any form will be impossible without significant improvements in automation and the inherent benefits:

• The acceleration of process execution.
• The reduction in human errors and the unwanted consequences.
• The ability to rapidly adapt as both business and IT needs change.
• Reduction in the cost of IT operations.
• The ability to proactively respond to the shrinking "available resource pool."
• Freeing highly skilled and knowledgeable staff from the repeatable, mundane tasks.

An automation example from the report is shown below:

But remember that for a bad process with a bad business outcome, automation just lets you get to the bad outcome more quickly.

Combining Service Management And Automation Amplifies Benefits

While the SMA report looks in detail at service management and automation used in isolation, the benefits can be extended by using both disciplines in tandem. Self-help password resets is a common but powerful example; FastPass [3] Corporation estimates the fully burdened cost of a password reset is $18 per support call, not factoring in loss of productivity. Other common examples include service catalog workflow, automation for provisioning, or remote support and chat (a chat example is shown below).

Leveraging automation for ITSM brings with it a number of benefit-enhancing advantages: It helps to remove people dependency, people costs, and human error; it speeds the time to enact a given process; and it results in a better IT service delivery experience and hopefully a better customer experience (and greater customer satisfaction).

In Forrester's opinion, automation is the future of IT service delivery (please don't read this as contradictory to my continued push for greater customer-centricity — the two aren't mutually exclusive) and as my esteemed colleague Glenn O'Donnell says:

Lima Level Kepemimpinan

Lima level kepemimpinan

1. Posisi / rights (hak)

Orang mengikuti Anda karena mereka harus melakukan hal tersebut. Catatan: Pengaruh Anda tidak akan melampaui batasan-batasan deskripsi pekerjaan Anda. Semakin lama Anda bertahan di sini, semakin tinggi perputaran karyawan dan semakin rendah semangat juang.

2. Izin / Relationship (hubungan)

Orang mengikuti Anda karena mereka ingin melakukan hal tersebut. 

Catatan: orang akan mengikuti Anda hingga melampaui wewenang yang ditetapkan kepada Anda. Level ini akan memungkinkan pekerjaan menjadi sesuatu yang menyenangkan. Peringatan: bertahan terlalu lama di level ini tanpa peningkatan akan mengakibatkan orang-orang yang bermotivasi tinggi menjadi gelisah .

3. Produksi / Result (hasil)

Orang mengikuti Anda karena yang telah Anda lakukan untuk organisasi tersebut.

Catatan: ini adalah tempa kesuksesan dirasakan oleh sebagian besar orang. Mereka menyukai Anda dan apa yang tengah Anda lakukan. Berbagai permasalahan terselesaikan dengan upaya yang sangat sedikit berkat momentum tersebut.

4. Pengembangan diri / Reproduksi

Orang mengikuti Anda karena apa yang telah Anda lakukan untuk mereka. 

Catatan: ini adalah tempat pertumbuhan jangka panjang terjadi. Komitmen Anda untuk mengembangkan para pemimpin akan menjamin pertumbuhan yang berkelanjutan bagi organisasi dan manusia yang di dalamnya. Lakukan apa pun yang dapat Anda lakukan untuk mencapai dan bertahan di level ini.

5. Kedirian / Respect (rasa hormat)

Orang mengikuti Anda karena siapa Anda dan apa yang telah Anda representasikan.

Catatan: Langkah ini ditujukan bagi para pemimpin yang telah menghabiskan waktu bertahun-tahun untuk mengembangkan orang lain dalam organisasi. Hanya sedikit yang berhasil. Mereka yang berhasil adalah orang-orang yang mengagumkan.

Teologi Kucing dan Anjing

Oleh: Princess E Diary | 06 March 2011 | 01:49 WIB



Anjing berkata, "Kau mengelusku, kau memberiku makan, kau memberiku tempat tinggal, kau mengasihiku, engkau pasti Allah."
Kucing berkata, "Kau mengelusku, kau memberiku makan, kau memberiku tempat, kau mengasihiku, aku pasti Allah."
Berawal dari penggalan dua kalimat diatas di halaman belakang buku "Teologi Kucing dan Anjing" ini membuatku bertanya-tanya, apa ya maksudnya dengan kalimat-kalimat ini?
Mungkin dari para pembaca ada yang sudah bisa menebak apa maksud dari kalimat diatas? Kalau aku sih sama sekali tidak ada gambaran sama sekali waktu itu, hahaha…. ( ngaku nih )
Daripada terlalu lama kita bingung, lebih baik aku bagikan disini apa yang berhasil aku tangkap dari Teologi ini.
Teologi Kucing dan Anjing, menginstropeksi hubungan kita dengan Allah
Teologi Kucing dan Anjing ini adalah Teologi yang didasarkan atas perbedaan sifat kucing dan anjing dianalogikan dengan bagaimana hubungan kita dengan Allah.
Bagi pembaca yang memelihara anjing atau kucing di rumah, yuk kita perhatikan perbedaan sikap mereka terhadap majikannya.
Kalau anjing memiliki sifat "setia dan suka melayani", masih ingat kan dengan cerita "Hachinko" yang mengharukan dimana dia setia menunggu majikannya pulang dengan duduk di bundaran stasiun selama 9 tahun meskipun majikannya sudah meninggal karena serangan jantung. Hal ini tidak lain karena sifat anjing adalah "setia mengabdi".
Lain lagi dengan kucing yang memiliki sifat "angkuh dan mandiri", bagi seekor kucing hal yang harus menjadi pusat perhatian adalah dia, oleh karena itulah kucing lebih memilih dilayani dan dimanjakan oleh majikannya.
Anjing punya majikan, kucing punya pelayan. Itulah yang tepat untuk menggambarkan perbedaan diantara keduanya.
Jika kita tarik kembali kearah memaknai hubungan kita dengan Allah, tanpa sadar kita terjebak menjadi "kucing" dan bukan "anjing" dalam berhubungan dengan Allah.
Lebih jelasnya, mari kita sama-sama mencoba untuk jujur dengan diri kita sendiri.
Benarkah selama ini kita hidup untuk memuliakan nama Allah?
Ataukah kita justru mendikte Allah untuk memanjakan diri kita, menuruti kemauan kita?
Allah, tolong berikanlah aku seseorang yang seperti Leonardo di Carpio ya,  tapi jangan memiliki sifat bad boy seperti itu, tapi biarlah dia memiliki sifat seperti Hachinko yang setia sampai mati.
Nah lho, memangnya Allah bisa diperintah untuk memberikan sesuatu sesuai dengan kemauan kita? Terkadang apa yang kita inginkan itu belum tentu yang terbaik untuk kita kok, siapa tahu pada waktu sudah mendapatkan yang setia malah jadi bosan karena nggak ada tantangannya? hahahaha….
Kalau melihat contoh permohonan doa diatas berarti seolah-olah Allah itu hidup untuk menuruti kita dan bukan kita untuk Allah. Terbalik kan?!
"Karena di dalam Dialah telah diciptakan segala sesuatu, yang ada di surga dan yang ada di bumi, yang kelihatan dan yang tidak kelihatan, baik singasana, maupun kerajaan, baik pemerintah maupun penguasa ; segala sesuatu diciptakan oleh Dia dan untuk Dia." ( Kol 1 : 16 )
Seandainya segala sesuatu diciptakan untuk kita, mengapa Allah menciptakan 3/4 bumi ditutupi air? Coba renungkan. Kita sebagai manusia tidak bisa hidup diatas 3/4 dari permukaan bumi.
Why?
Karena segala sesuatu di dunia diciptakan untuk Dia, bukan untuk kita.
Penciptaan dilakukan untuk Dia dan untuk menyenangkan hati Nya!
Itulah sebabnya kita sebagai salah satu ciptaan Allah, haruslah mengingat hal ini.
Kita hidup untuk Allah, bukan Allah hidup untuk kita!
Semoga perenungan sedikit ini memberikan sedikit sentilan ke kita ( termasuk penulis sendiri ), agar mulai sekarang tidak akan menjadi "kucing" yang hanya berfokus pada diri sendiri tapi menjadi "anjing" yang setia mengabdi untuk kesenangan majikannya.

Kehidupan bukan tentang kita, melainkan tentang Allah !
~Happy Sunday All~
