ブルネイの通信エリア

ブルネイ の数値が意味すること

重要な数値は2つあり、どの会社も引用するのはそのうち1つだけです。一般的な速度は58 Mbps。調子のいいときがどれくらいかを示す数字です。

読む価値があるのは10パーセンタイル、15 Mbpsのほうです。駅の上の基地局が混み合い、周りの全員が同じ電波につながっている、その日の下位1割のときの速度です。中央値が高くて下限が低い国は、本当に必要になるその瞬間まではみごとに動く国だということです。

ビデオ通話やテザリングが欠かせない旅なら、一般的な速度ではなく混雑時の数値を基準に計画してください。

ブルネイで回線が混んだときに起きること

混雑は故障ではなく、火曜の夜です。問題は、そのときeSIMに何ができるかで、たいていの旅行用eSIMの答えは「何もできない」です。国ごとに卸契約が1つ、ネットワークが1つ、路上に立ったまま他社のeSIMをもう1枚買う以外に逃げ道がありません。

ここではOrbisloの通信はDST、Imagineを通ります。いま乗っているネットワークが劣化したら、旅行の途中でも、お客様が頼まなくても別の回線へ移します。そのときに邪魔をするのではなく、あとからお知らせします。

ブルネイの携帯キャリア

• Unified National Networks (UNN): From 1 September 2019 the networks of TelBru, DST, Progresif and the international gateway operator BIG were merged into Unified National Networks, a company wholly owned by the Brunei government, which now runs the country's single mobile radio network.
• DST, imagine and Progresif: Brunei's three retail providers, DST, imagine and Progresif, sell mobile plans on top of UNN's wholesale network. Changing provider changes the plan and the customer service, not the towers a phone connects to.
• UNN, network size: UNN runs more than 600 mobile base stations carrying 3G, 4G and 5G, which it says reach 94 percent of populated areas and connecting roads, alongside over 5,000 km of fibre.
• DST, VoLTE: DST offers VoLTE at no charge to its 4G and 5G postpaid customers and its 4G prepaid customers. A VoLTE call that leaves 4G coverage continues on the 3G network, possibly at lower quality, rather than dropping.

• UNN phased out 2G GSM and completed the shutdown by 1 June 2021, reusing the spectrum for 3G and 4G and later 5G. A phone that only supports 2G cannot connect to any network in Brunei.
• Mobile service in Brunei began in 1989 with analogue AMPS; DST introduced GSM in 1995, 3G arrived in 2005 and 4G in 2014.

ブルネイの5G

• 5G went live nationwide on 22 June 2023, announced jointly by the regulator AITI with UNN, DST, imagine and Progresif. At launch, 90 percent of populated areas had 5G ready mobile coverage, and a 5G capable phone is needed to use it.
• By the end of 2022, 92 percent of the country could receive service from 5G ready base stations, the result of a radio network modernisation UNN began in 2020 that added base stations in both populous and rural areas.

• The regulator's quality code requires 3G voice coverage over at least 80 percent of populated urban areas and 60 percent of populated areas classed as island locations, measured from a moving vehicle, and limits dropped calls to 2 percent per urban cell site and 3 percent in island locations.
• UNN co-owns three submarine cables, SEA-ME-WE 3, Asia-America Gateway and the South-East Asia Japan Cable, and reroutes traffic between them when one is damaged. Planned maintenance on a cable can last one to two weeks, and repairs longer.
• AITI's temporary limits on new mobile entrants ended on 1 January 2025, when the telecom market was fully liberalised. The regulator still expects few infrastructure licences because of the size of the market.
