3G

3G is the fourth generation of mobile phone standards and technology, superseding 2.5G, and preceding 4G. It is based on the International Telecommunication Union (ITU) family of standards under the International Mobile Telecommunications-2000, IMT-2000.

3G networks enable network operators to offer users a wider range of more advanced services while achieving greater network capacity through improved spectral efficiency. Services include wide-area wireless voice telephony, video calls, and broadband wireless data, all in a mobile environment. Additional features also include HSPA(High Speed Packet Access) data transmission capabilities able to deliver speeds up to 14.4Mbit/s on the downlink and 5.8Mbit/s on the uplink.

Unlike IEEE 802.11 (common names Wi-Fi or WLAN) networks, 3G networks are wide area cellular telephone networks which evolved to incorporate high-speed internet access and video telephony. IEEE 802.11 networks are short range, high-bandwidth networks primarily developed for data.

NCC vows to protect telecom infrastructure from vandalism

The Nigerian Communications Commission has vowed to protect telecommunication infrastructure in the country from vandalism, a promise made by NCC Vice Chairman Ernest Ndukwe at a stakeholder’s forum last week.

Addressing an audience comprised of telecommunication service providers, Ndukwe emphasized that operators also hold a great deal of responsibility in the protection of their infrastructure, noting that vandalism sets back development in the sector. “This means that they must take the security of their data and network seriously,” he declared of service providers.

Ndukwe advised operators to establish corporate security plans and look for ways to work together on critical infrastructure protection for the benefit of customers.
“NCC cannot do everything,” Ndukwe said. “It would only regulate and ensure that the system is moving. When you come together to fight the same cause, it will help to solve substantial problems.”

The federal government considers telecommunication infrastructure to be public property of strategic importance; hence, it is criminal to vandalize it, Ndukwe noted. The NCC will seek the support of the police and security agencies in training those who can assist in safeguarding the infrastructure, he said.

“We will revisit the law of willful damage and enforce the law of compensation, so that when you are billed for willful damage, it may not occur again,” he added. Some participants at the forum suggested that the commission direct operators on how best to construct cables in the future to avoid damaging competitors’ cables.

“Operators should submit their drawings to the commission to help identify the defaulter when one damages each other’s cable,” suggested Val Amadi of Etisalat.

Martins Oluwale of Globacom, on the other hand, suggested the NCC collaborate with the Ministry of Works and state and local governments to help ensure that telecommunication infrastructure is not damaged while constructing roads. He further recommended a harmonized policy for cable installation and laws that would make operators live up to their responsibilities.

Mobile operators get fewer customers


Customer acquisition by the six mobile phone operators dropped 45 percent to 0.6 million in August from 1.1 million in July. Bangladesh Telecommunication Regulatory Commission (BTRC) data showed that not a single customer was added to Grameenphone’s network in August. The mobile company’s customer base remained unchanged at 20.84 million during the month.

The company officials said it happened as GP strictly complied with BTRC’s re-registration process. As per the company’s customer acquisition process, GP considers a customer ‘active’ when he or she remains with the company’s network for three months after getting connected.

So the new customers who signed up for Grameenphone connection will be added to the existing customer base at the end of September.

“The unchanged customer base is due to a general market slowdown, strict compliance with proper registration and a bar on non-registered customers after the end of BTRC deadline,” said Anders Jensen, chief executive officer of Grameenphone.

BTRC data showed that the number of mobile phone subscribers reached 45.4 million in August, which was 44.8 million and 43.7 million in July and June, respectively. Earlier, in August last year BTRC issued an order to Grameenphone, AKTEL, Banglalink, Citycell and TeleTalk to re-register customers who bought connections before February 28, 2006. BTRC extended the deadline four times, which finally ended on May 31.

According to BTRC data, the top three operators are still dominating the market.

Banglalink, the market’s second largest operator, has a customer base of 10.17 million with an addition of 0.27 million in August, followed by AKTEL’S 8.14 million, adding 0.16 million in August. In terms of subscriber base, top three companies Grameenphone, Banglalink and AKTEL dominates more than 90 percent of the market, according to the BTRC.

The other three other operators — the country’s oldest mobile operators Citycell, state-owned Teletalk and UAE-based Warid — hold the rest of the market shares.
The top three operators hold 39.154 million until August 2008, while the rest three hold only 6.25 million. According to BTRC, Teletalk lost 0.04 million customers in August. The company’s customer base was 0.93 million in July.

Citycell’s subscribers increased 0.01 million to 1.68 million in August from 1.67 million in July 2008. Warid subscribers reached 3.68 million at the end of August, while the company’s subscriber base was 3.48 million by the end of July 2008.
