Welcome to 2014 - a year of technology virtual possibilities. Last year, we witnessed a lot in terms of IT & Telecom development. This year, a lot will also happen. In Nigeria, we hardly utilize 15% of the total development.

With android phone everywhere and prices coming down, BBM, whatsapp and 2GO on android, communication by online chatting will increase this year. This means broadband penetration into every part of the country is more needed.

Also, as engineers distribute internet from GSM using 3G/4G routers in states and towns where WiMax is not available and no ISP is available, efforts must be concentrated on the use of 3G/4G routers on Visafone and other CDMAs that have their presence in states and towns with low broadband penetration. Using CDMAs 3G modems on 3G routers have been a major challenge with only very few of those modems working and those working modems are not always available.

Whoever has any configuration file of these CDMA modems can send them to manufacturers of 3G/4G routers like TPlink, Dlink, etc for update on thier 3G database. You can also inform us on this forum.

Thanks and welcome to 2014.

I am sorry for not coming up with write-ups on VPN routers as promised the last time. This is due to end of the year tasks that are keeping me busy. Meanwhile, I wish Mr. Seun, Nairaland Team and readers of my postings on different fora a Merry Xmas in advance. This year has witnessed a lot of development in the IT & Telecom sector. Gradually, things are changing for better in Nigeria in terms of IT development.

I remember in the late 90s and before 2001, IT , particularly telecom was in a mess in this country. As a young telecom engineer and head of IT in a dynamic organization, internet and telephone lines were the major headaches of organizations. To make a trunk call between Lagos and PortHarcourt was very difficult. PortHarcourt and Tema (Ghana) are our operational base, 'all trunk lines are busy' was the dominant response we often get from NITEL despite spending a fortune on NITEL Bill. We hardly get our other offices in states across Nigeria and our International Offices despite IDD facility. With this frustration, we got Inmarsat - Satellite Phone system to make calls between Lagos and PortHarcourt and also Tema in Ghana (we paid in dollar for every second of call).

Internet was a Mirage. I never knew internet connection could be so easy this way. You can spend two days trying to upload 20kilobit of data. We were using dial-up, having a successful connection to the few ISPs using digital Nitel lines (most lines are analogue in some states and in Lagos) was a game of chance. Once a successful connection is established, you may loose the connection and never have the luck of another connection before the close of work. VSAT was not allowed by then. Browsing was very difficult and frustrating. You may wait for up to 5 minutes or more to open a page.

Also, getting a telephone line (Nitel, Intercellular, Multilink, EMIS, etc) was very difficult and expensive. There was a time only CDMA lines were available in Lagos area, except NITEL retrieves an unused or abandoned line from another customer. I remember between 1999, 2000 and early 2001, I have paid =N=115,000 for one CDMA desktop line, during the same period, I have paid =N=145,000 for one CDMA mobile phone. The mobile CDMA, though with less features when compared to the present CDMA mobile phones was more expensive than the desktop cdma phone because mobile phone was considered a class status by then. The analogue Nitel Mobile line (090) was also very expensive and difficult to get. You will have to pass through some accredited NItel Mobile line dealers. I got some Nitel mobile (analogue) lines for My MD and other management staff at a cost of over =N=200,000 each.

I have written this memoir for the younger generation, the new IT and telecom engineers and other users of technologies to have a background of where we are coming from, and where we are today. This will enable us to appreciate those who have contributed to this development. I remember late Engr Charles Joseph (RIP), Engr Ernest Ndukwe, Dr Emmanuel Ekuwem, Engr. Titi Omo-Ettu, Mr. Jim Ovia, Mr. Chris Uwaje, Prof Pat Utomi and a lot of other personalities that have contributed immensely to the IT development in Nigeria.

Among the names mentioned above, Mr. Jim Ovia will be remembered for his contributions to the IT & telecom community in Nigeria and particularly, the banking sector by giving Zenith Bank the power of information technology which has indirectly affected the entire banking sector, laying the foundation for the cashless society.

I will be talking about VPN routers later today

LOAD BALANCE ROUTERS. Few days ago, some people have been asking a lot of questions on Load Balance Routers. Basically, a load balance router shares load across multiple internet connections. For techies, it can also be used in a multi gateway situation. In its simplest term, it enables you to use your swift, spectranet,MTN MiFi, IPNX, etc simultaneously in the same home or office at the same time. When one network is down, the active network continues to give connection to all the systems until the failed network becomes active again. They are rated in terms of the number of WAN port supported. The common one is the Dual WAN load balance router supporting two modems together. You can use MTN MiFi and Swift, or Spectranet and IPNX modems together to increase internet availability for your home or office.

Powerline Adapters. In concluding the brief write-up on wireless range, I would like to remind us (techies) of an active device that can be helpful in indoor situation but are long forgotten or never used by most of us, this is the powerline adapters. In Nigeria, power situation and poor wiring might be an obstacle, in most corporate environment, these obstacles are non existence. Powerline adapters can be used to extend range without any cabling or drilling. It uses the domestic electrical wiring of the building. Just plug an adapter as you would for normal electrical appliance, connect it to the router or access point at one point, connect the other at another point, it might be up to 300metres distance (remember, cat 5 has 100metres distance specification, powerline goes further than cat 5), plug a wireless router at that end and connect systems at that environment. There are some other powerline adapters that have wireless facility. Doing this, you have taken the internet connection or network to another location without cabling or usage of multiple indoor repeaters.

I will be talking on wireless range today. The speed often mentioned by the designers of wireless products are just theoretical speeds. The speeds are based on calculations made under ideal situation scenarios. Ideal situation does not exist anywhere. The range of wireless routers and access points are limited by the resistance it encounters. The wave is either reflected, or deflected or absorbed. Therefore, from experience, we noticed that the lower speed or data transfer per second, the longer the range. For example, from radio installation, a 22mbps installation will go further than 54mbps or 108mbps for the same type and model of radio. This is even evident in copper and fiber installation, for a poor cable with packet loss at 1gbps or 100mbps at some long distance, downgrading the speed from network card to 10mbps always solve this problem. Also, while some media converter operating at 10/100mbps to fibre interface can support up to 2kilometer on multimode fibre cable , a gigabit media converter with 1gbps copper interface to gigabit fibre interface can only support about 550metres on multimode fibre cable.

Back to wireless range, range can be extended by increasing the power output. This is the reason why high power ouput rating, the gain of the antenna are key to range. In some countries, there is a limit to transmitting power rating because of health hazards. some people tend to increase the power with the installation of power amplifiers. With indoor radio, separate power amplifier are not always possible. Because of this limitation, people try to buy high speed routers or access points that can go far by design.

Personally, I noticed that people often make mistake by buying the wrong routers or access points by paying for the facility they may never use. Makers of wireless LAN products will state the combine frequency as the capability of the router. Example, a router operating on dual frequencies with 500mbps on 2.4GHz and 500mbps on 5 GHz will have a combine capacity of 1Gbps speed displayed on the products. In Africa, 99% of people buying this router will only use one of the frequencies at a time. This means that they are only buying a router operating at 500mbps. Obstructions on the path will also absorbed some of the signals, at the end, while the speed is fantastic for those closer to the routers, those far away are still having unstable or no connection at all. Therefore, higher radio has not solved the problem as expected.

Will continue next time

Internet access is improving in Nigeria now. From experience, KU - Band VSAT has poor quality of service when compared to C-band vsat due to environmental (weather) and other factors. Also, the operators are not sincere on contention ratio and technical/financial issues with their Tier 1 provider and problems from their own NOC. NCC should assist with fiber penetration in all the local governments in Nigeria especially with USPF money. Last mile connection of fiber through radio to customers premise is the best. There is no any explanation any user or staff of DOPC can give to cafe operators in 2013 about the performance of DOPC KU-Band VSAT is tenable. In Lagos, DOPC outdoor radio installation is working perfectly. Also, the wimax has improved since their alliance with SWFT.

I will advice anybody in states or local government where there are 3G services or visafone or any other cdma internet services to subscribe to them for now. They can combine two services (operators) together using 3G/4G routers and Load Balance routers.

Wireless world? Let us discuss your problems, issues and solutions here

This is to notify some people that are complaining of difficulty in installing some Visafone modems on 3g or 4g routers. Actually, it has been confirmed that visafone Alcatel modem only works on direct connection to computer. It does not work on any router. I think the solution is to get the bin file. Also, a particular Visafone huawei and ZTE modems will not work with routers as well, while other huawei and zte modems work. The models that work must be identified before procurement.

To avoid these problems, for those that can afford it, the new visafone mobile router and desktop phone/router are available for multiple systems connection. Note: These new routers have no LAN port, they are just wireless connection. If you require LAN connection or wish to expand the wireless range, you can do these through wireless/LAN converter and extend wireless range also.

There are other routers and network devices can aid internet distribution and support internet infrastructure for operators like swift, spectranet,iopnx, mobitel, cobranet, visafone, etc
